ENTASYS Selected For Elementary School Multi-Purpose Room

The ENTASYS system helped to create a versatile performance space within an average multi-purpose space.

One of the busiest places in Ocean Road Elementary School is the multi-purpose room.

Hosting everything from lunch periods to presentations and performances, the “cafetorium” is a non-stop hub of activity from before classes begin until late into the evening.

It’s an open, acoustically live space that’s designed more for versatility and utility than for sonic performance. Crowds of kids and a loud HVAC system contribute to the room’s typically high ambient noise levels.

School officials were unhappy with the performance of their present sound system, and needed a system that would be effective and versatile enough to perform daily for announcements, after school programs, and a range of music and theatrical events.

“We had installed a Community Veris system Nellie Bennett Elementary, another school in the Point Pleasant Borough School District, and when the folks at Ocean Road heard it they asked us to come demo a system for them,” says Joe DiSabatino of Chews Landing, NJ-based JD Sound and Video.

“We set up an ENTASYS as well, and they were just amazed with the quality They wanted us to install it immediately.”

The system is configured as one ENTASYS full-range column and one ENTASYS low frequency column per side. A pair of VERIS 212 subwoofers are mounted on custom brackets above the ENTASYS.

“The ENTASYS systems deliver great spoken word intelligibility, and even with all the microphones open, the kids can walk right by the columns and get no feedback.” Crown XT-series amps power the system.

“Everyone is extremely impressed with the system,” DiSabatino continues. “The kids can stand on choir risers right in front of the columns and not be blasted out, while the parents all the way in the back can hear their sons and daughters loud and clear.”

“And the VERIS subs add a nice, smooth bottom end, which is great during movie days.”

Hartselle Church Congregants Rely On Iconyx

The Hartselle Church of Christ chose Iconyx to combat several unforseen challenges created by the pristine architecture of the church.

Hartselle Church of Christ which boasts beautiful, inspirational architecture featuring high ceilings and ornate brickwork, i’s an impressive looking sanctuary..

However, that same architecture created some unforeseen challenges. As Christopher Bragg, Senior Systems Engineer at Covington, GA-based Messenger Media Systems Inc., explains, the room’s acoustic signature did not lend itself to getting the message across to the congregation.

“It’s a very wide room, and very reflective,” says Bragg.

“As a traditional Church of Christ, their service is very much centered around the spoken word. And while those brick walls look great, they can create problems with intelligibility, making it difficult to clearly discern what’s being said.”

The reflective nature of the space called for a highly focused loudspeaker system that offered powerful beamwidth control, and Renkus-Heinz’s Iconyx digitally steerable array system fit the bill. “When I walked in the room, I knew immediately that Iconyx was the only option,” says Bragg.

A pair of Iconyx IC16/8-R loudspeakers are installed into custom soffits on either side of the proscenium. As Bragg explains, the Iconyx’s low-profile design also addressed the church’s concerns for minimal visibility.

“Aesthetics were of the utmost importance,” says Bragg. “They did not want to see the speakers.”

“We worked with the architect, and had them leave an opening in the brickwork on either side of the proscenium. The Iconyx fit in perfectly, and we put a bit of standard molding around it. It looks terrific.”

A pair of CFX81 compact 8-inch two-way loudspeakers, mounted behind a small façade, provide side fill, and two Sygma-Series SGX41 4-inch two-way boxes are installed at the rear wall for the sound booth.

“We’ve received lots of compliments on the sound quality,” he says. “The sound is clear, natural and articulate to every seat in the house.”

Rechargeable Batteries - Why You’ve Been Burned

If the last rechargeable's you tried were a $10 K-Mart special maybe it's time to give serious batteries a chance.
This article is provided by ChurchTechArts.

One of the most fascinating topics I’ve ever written about has to be rechargeable batteries.

I’ve tweeted about and read countless comment threads on the topic and there seems to be three camps of people in the rechargeable battery debate.

The first group has used them for years, loves them and wouldn’t consider going back to alkaline batteries.

The second group has never used them, though most have heard the horror stories and are leery. The third group has tried them, and had bad experiences.

The phrase, “I’ve been burned too many times, I’ll never trust them,” has been thrown around dozens of times just in the last few weeks. This article is for the second and third groups.

If you’ve been burned, I’m going to explain why, and if you’ve heard the stories, I’ll show you how to avoid them.

By way of introduction, know that I have been using rechargeable batteries in wireless mics (and a lot of other stuff) for almost four years. I’ve tested them, and have gone through hundreds of services using rechargeable batteries without a problem.

Yes, hundreds of services. Far too many people have one bad experience, don’t investigate the cause and swear them off. The fact is, I’ve had just as many ProCells die on me at the wrong time as I have rechargeable cells–and in each case, it was always been my fault—I simply forgot to change them.

There are four things you need to know in order to get the most out of rechargeable batteries. Failing to understand and implement these things will guarantee bad experiences. However, trying to stretch a ProCell for 2 weekends worth of services is a bad idea, too.

Keep in mind that rechargeable batteries behave differently than alkalines. Expecting them to be the same will only frustrate you. However, follow these guidelines and you’ll have great success; and save a ton of money.

Use Good Batteries
This is one of the key factors in getting good results. A lot of people went down to K-Mart 10 years ago, picked up a $10 pack of four NiCd AAs and a charger, tried them in their mics and went down in flames. That explains 50% of the “bad experiences.”

To use rechargeable batteries in wireless mics, you need to use a more modern chemistry, Nickel Metal Hydride, or NiMh. The batteries need to be rated for at least 2000 mAh (I like 2500 and higher). mAh stands for milliamp hours and is provides a guide as to how much energy the battery can store.

If you pull open your junk drawer and find a bunch of 1300 mAh NiMh batteries that are 5+ years old, that may explain the other 50% of the “been burned” statements.

A ProCell is rated for somewhere around 1800 mAh. The modern, high quality batteries from Sanyo, Powerex and Ansmann (with ratings from 2700-2850 mAh) absolutely blow ProCells away; as I’ll show you in an upcoming series of test results.

Even a 4-year old Ansmann 2700 beats a ProCell by almost 4 hours. And these newer batteries are rated for between 500-1000 charge cycles. Figuring one or two cycles a weekend, that could easily mean 5 years or more on one set, provided they are taken care of.

If your experience with rechargeable batteries does not include these newer batteries, you simply don’t have enough experience to make an informed decision.

So good batteries are important, but there is another component.

Proper Charging
The second key component to proper use of NiMh batteries is the proper use of a good charger.

Using a cheap “rapid” charger will not fully charge the cells, will overheat them and shorten their life.

Modern, smart chargers are readily available, easily affordable and will charge the batteries at the correct rate to fully charge them, while avoiding over-heating.

They will then switch to a trickle charge mode to keep them at peak capacity.

So what is a “proper charge rate?” Most battery manufacturers recommend a charge rate that is between 0.5-1.0c. That is to say, the charge rate should be one half to full capacity of the battery.

So, if a battery is rated at 2000 mAh, the recommended charge rate would be 1000 mAh, and max charge rate 2000 mAh. A full charge will take from 1-2 hours at those rates, respectively.

If you have the time and want to extend the life of the cell, charge at .25c. Sanyo recommends a charge rate between 300-500 mAh for their Eneloops (rated at 2000 mAh). Charging at those rates will give you somewhere between 500-1000 cycles, according to Sanyo. The other batteries I tested have similar ratings.

Personally, I like chargers from BTI, Maha or Ansmann; especially the ones that have selectable “soft” charge rates. I buy enough batteries that I can spend 4 hours charging them, so I charge at 500 mAh. Once the batteries are well charged, it’s important to know how to utilize them properly. And that brings us to…

Proper Cycling of Batteries
To ensure good results (“good” defined as the mic not dying mid-service), it’s important to use the batteries properly. Fully charged batteries should always go straight from the charger to the mic. Once the charger is empty, it should be re-filled with another set of batteries.

When the service or event is ended, remove the batteries from the mics, and charge. If you have enough charging bays, you can simply alternate from one set to another. However you do it, you always want to go from charger to mic.

The reason is that NiMh batteries will self-discharge over a period of 30-60 days. So while you may not lose a lot of capacity from Sunday to Saturday, you’ll be down 10-20% or so. Why push it? Go straight from charger to mic, and charge immediately afterward. Keep a set on the charger all week and you’ll always have fully charged batteries to work with.

Some are concerned about the “memory effect,” the loss of capacity that happens when NiCd cells are recharged before being fully depleted. NiMh cells have no significant memory effect, so charge them when you’re done using them. Don’t stretch them farther than needed.

Good chargers include a refresh cycle that will fully discharge each cell, then fully charge it again. It’s a good practice to do this every 3-4 months. This procedure will prolong the battery’s life and ensure top performance.

Understanding Discharge Curves
Another main factor in the “I’ve been burned” phenomena is the different discharge curves between an alkaline and NiMh battery. An alkaline battery drops off in a pretty linear fashion.

A NiMh, on the other hand, quickly drops from full voltage to something less than that and holds there for a long time. When it drops off, it drops of the cliff very quickly.

Most battery meters in wireless mics are calibrated to the discharge curve of an alkaline battery. As the voltage drops off, the meter can predict approximately how long the battery is likely to last.

However, with a NiMh, the voltage holds, then falls off very quickly. This is why it’s not uncommon to see a NiMh battery go from 4 bars to 0 in 5 minutes. The meter has no idea how to know where the battery is.

Some newer mics have battery meters that can be switched between alkaline and NiMh (the Shure UHF-R does for sure), and those can be a help.

Discharge curve of the Eneloop (blue), a Sanyo NiMh (black) and an Alkaline (pink). I grabbed this from Sanyo’s Eneloop website.

However, there’s still no substitute for doing some testing and finding out how long they last in your mics.

Once determined, you know how often you need to change them, regardless of meter reading.

For example, I know that the Powerex and Sanyo 2700 mAh batteries will run a good 12-14 hours in our mics. So, I can feel confident putting them in Saturday afternoon for rehearsal and letting them run through end of service (about 4.5 hours total).

I can then put in a fresh set Sunday morning and be fine through the end (about 5 hours total). I don’t expect to ever have one go down, unless it’s a fluke. But again, that happens with ProCells, too.

Those are some basic principles for the proper care and feeding of NiMh batteries.

If you haven’t tried them lately, you should really give them a chance.

Are you a fan of rechargeable batteries? Have you recently switched? Let me know in the comments below!

Harman Professional Appoints John Goodrich Global Sales Manager For Mass Communications

Goodrich to provide systems integrators and clients in the mass communications vertical market with specialized attention, support and programs.

Harman Professional has announced the appointment of John Goodrich to the newly created position of Global Sales Manager for Mass Communications. 

Goodrich joins Harman Professional from Altel Systems Group, where he was Vice President of Business Development, leading the development of integrated audio/visual and communication systems for the airport, mass transit, and hospitality industries. 

He previously held senior sales and business development roles at Meyer Sound Labs and Innovative Electronic Designs (IED). 

In his new role, he will report to Michael MacDonald, Harman Professional Executive Vice President of Marketing & Sales, and will be responsible for developing Harman Professional’s presence in the mass communications market.

According to Michael MacDonald, John Goodrich’s appointment marks an important strategic step by Harman Professional to grow its business and provide customers in a host of vertical markets with a higher expectation level for audio performance and integration. “In some verticals audio has been commoditized and as a result communication has suffered,” said MacDonald. 

“Harman Professional brings professional-grade systems that are proven at the highest performance level but designed to suit the needs of mass communication and other verticals.  John Goodrich is the person to bring these systems to market; to work with integration partners, end-users and our own product designers to ensure that we enable better sound in more places than ever before imaginable.”

“Harman Professional’s dual strength in systems integration and audio performance presents a compelling opportunity to integrators and their clients in mass communications,” said John Goodrich.

“I look forward to working with Harman’s design teams and with our customers to advancing public address audio for communication, entertainment and life safety in the domestic and international markets.”

Earlier this year at the 2010 InfoComm Expo, Harman Professional launched a partnership with information display and paging specialist Com-Net Software to launch a series of new communication technologies starting with the co-branded IDX Information Delivery Systems.

The IDX System couples Harman’s Crown CTs, BSS London and HiQnet technologies on the back end with Com-Net Software ECLIPSX Flight Information Display System or ECLIPSX Transit Information Display System at the front end.  The combined result is great sounding, highly reliable audio networks with application-engineered interface and control in a versatile, cost-efficient package.

“IDX is remarkable,” Goodrich said.  “I applaud Harman for not seeking to reinvent the wheel on the front-end software and interface but instead integrating a high-performing, back-end audio network with a proven mass communications system and interface from Com-Net.”

“Its is literally and comprehensively the best of both worlds and I am very excited to be involved!”

Tech Tip Of The Day: Recording Vocals

The information you need to have a successful vocal session.
Provided by Sweetwater.

This Tech Tip Of The Day come to you in editorial form because we wanted to tackle one of the more difficult recording issues faced by engineers, whether a seasoned pro or a project studio newbie, recording vocals.

This job requires musical knowledge, technical expertise, possession of (or at least an awareness of) microphones, preamps and mixers, and a solid grounding in the psychology of performance.

However, we’re going to leave most of the equipment-related information for another time. This time out we’re discussing some equally important details.

Before you ever hang a microphone or move a fader, you must know your vocalist! You need to have a handle on his/her musical characteristics (pitch, range and timbre), technological skills (microphone technique, use of processing gear) and psychological needs (does he/she work well under pressure or need special encouragement?).

Even if you are recording your own band, take time to re-think the vocalists’ roles and requirements. This can save you hours of frustration and tons of hard feelings as your recording progresses!

There are a number of steps you can take to attain this knowledge. First, find any opportunity you can to listen to the performer in advance. It’s particularly helpful to hear them doing the songs you plan to record!

If the performer has a previous CD or even a demo tape, borrow and copy it for study. Or go see the group perform live and take notes. Even in an acoustically challenged club you can learn a great deal.

Focus on the lead vocalist: what’s his/her range (lowest practical pitch to highest)? Does he/she strain to reach the song’s high notes? If so you might suggest a key change before recording.

Is he/she “eating” the mic - e.g., using the proximity effect to enhance bass response on low-to-midrange notes? This can be a difficult habit to change and may lead to some careful jockeying of the vocalist and the mic in the studio.

How does the lead vocal “sit” in the mix? Is it out in front of the band (the case with much pop material) or does it blend more like another instrument in the overall sound (often an element of hard rock, metal or post-punk)? Is this intentional or just a reflection of poor live mixing?

Once you’ve made these assessments you can move on to background vocals. Ask similar questions but keep one extra thing in mind: often background vocal recordings sound better when sung by the lead singer, “accompanying” him/herself.

Are the group’s background vocalists strong enough to stand up to repeated listening? If not, you may have to do some treacherous psychological maneuvering in the studio as you persuade members to reduce their roles in the recording for the sake of better sound.

You need a combination of musical and technological knowledge to continue your preparations. Make some preliminary notes to remember important points. For example, although no two people have exactly the same range, average sopranos rarely sing pitches below Middle C. Their harmonics are most prominent at frequency ranges in which many live vocal mics have a presence peak; you may have to use equalization to capture that timbre.

Altos often exploit their low registers using the mic’s proximity effect to capture “breathiness.” Tenors sometimes have wide-open upper ranges that can easily cause clipping. Basses, while rare (Frank Zappa was a bass), call for a full-bodied low midrange response that is near many studio mics’ bass rolloff frequencies. You might do best by leaving your mic’s rolloff switch off and using mix equalization to tune in vocal and tune out noise.

If all this seems like a lot of work, it is! However, you’ll find that careful preparation before a session can save time and reduce stress in the studio, allowing you to focus on more creative issues. And that can only help you get the best recording possible.

As always, we welcome input from the PSW community and would love to know your thoughts on recording vocals. Feel free to let us know in the comments below!

Yamaha Systems Selected By Taylors First Baptist Church

The yamaha system finished what was initially a partial upgrade, making the mix of their contemporary service complete.

Taylors First Baptist Church in Taylors, South Carolina was chartered and established in 1864.

The ‘u-shaped’ sanctuary seats approximately 2,100, and with two services on Sunday mornings, the church serves a congregation of 3,000.

Recently, Palmetto Sound Works of Spartanburg, S.C. was contracted to perform an upgrade to their existing audio system originally installed in 1995.

About four years ago, the audio contractor performed a partial upgrade that included a Yamaha M7CL-48 digital audio console.

This year, the complete upgrade includes a second M7CL-48 along with Yamaha Installation Series IF Speakers, PC amps, and a DME 64n processor.

“The major challenge to installing a new system was being able to evenly distribute audio to a ‘u-shaped’ room, said Ben Babb, Palmetto Sound Works.”

“The stage and podium area are in the center with the seating area wrapping around three sides. Over 60% of the main floor is covered with balcony.”

“Therefore, getting sound under the balconies was one concern, and installing a processor that would handle this variety of delay zones and equalizations was a major consideration in the project.”

Taylors First Baptist was also having problems with some of the ‘dying’ components in their existing speaker system. Babb said that after Palmetto demonstrated the Yamaha IF 2115’s, a combination of IF2115’s, IF2112’s, IF2205’s and IF2108’s speakers were chosen to cover seven delay zones.

Danley TH115’s are used as subwoofers because of their compact size and available space at the church. Yamaha PC2001n and PC9501n amplifiers power the system.

The Yamaha DME64n digital mix engine is controlling the majority of the audio system. The M7CL at the front of house position is equipped with ES100 and EX cards to allow digital EtherSound communication between the DME64n and two ES168 stage boxes.

The DME64n is handling the system processing for the array of speakers, the delay for the seven zones, presets for when the stage is extended to pageant-style and the center down fills have to be attenuated.

“Our congregation noticed an immediate difference in terms of clarity and volume, states Jesse Lee, Media Director.”

“With the old PA, mixing a contemporary style worship service was problematic to the point of being completely underwhelming to everyone in the room, including our musicians and vocalists!”

“Since the installation, the Yamaha system has been able to handle everything we’ve thrown at it beautifully, including a full band and orchestra, vocal team and choir all performing simultaneously.”

JBL VERTEC Line Arrays Amplify The Commonwealth Games Of India

Northwest Productions And Sound supplied dozen of Vertec arrays and over a hundred Crown amplifiers for the event.

Bringing together more than 50 nations from around the world, the 2010 Commonwealth Games in Delhi, India opened its 12-day athletic competition with a large, multi-array JBL VERTEC line array system powered by Crown I-Tech HD amplifiers to support the opening ceremonies.

The system successfully filled the Nehru Stadium in New Delhi, occupied by more than 60,000 spectators and nearly 5,000 athletes. 

Audio production companies Norwest Productions (Australia) and (India) collaborated to implement Auditoria’s sophisticated event system design in the field.

Scott Willsallen of Auditoria, having already completed major games ceremonies such as the Athens 2004 Olympics, Doha 2006 Asian Games and the Melbourne 2006 Commonwealth Games, was contracted by the organizing committee for the Delhi 2010 Commonwealth Games to design and manage the audio system for both the opening and closing ceremonies.

Twenty-five distributed JBL VERTEC arrays lined the stadium to ensure everyone from the floor seats to the upper levels fully enjoyed the entertainment, which included performances from traditional Nagada drummers, who drummed to the beat of the countdown to the official start of the event.

Eight of the arrays featured three JBL VT4889 fullsize line array elements and 17 contained three VT4888 midsize line array elements, with each also including a fullsize VERTEC arrayable subwoofer.

One hundred and two Crown amplifiers, including 92 I-Tech HD amplifiers, powered the JBL VERTEC rig.  Harman’s HiQnet™ System Architect system software was used for configuration, remote control and monitoring of the system.

Norwest (Sydney, Australia) teamed with a regional, Mumbai-based sound production company,, to supply the entire audio package and crew for the Delhi games’ opening and closing ceremonies. 

“The VERTEC V4 DSP tunings are excellent. The only additional tuning we had to do was some minor notch filtering to tidy up the response in the venue,” stated Willsallen. “It was all very subtle filtering. If it came down to it, we could have run the show very successfully without any additional E.Q. filtering.”

On the field of play, 25 JBL SRX712M speakers were used for the performers’ monitor system, while 32 JBL CBT70J column speakers and JBL SRX718S subwoofers were used to ensure that athletes on the field could experience the event’s sound. On the main stage, JBL VRX915M monitor wedges were utilized for musical performances.

“Norwest Productions and combined their resources and skills to deliver an excellent audio system, which met the performance requirements of my design and worked within the project budget,” said Willsallen.

Tech Tip Of The Day: Balanced Power

Can balanced power solve your ground problems?
Provided by Sweetwater.

Q: How does balanced power help to solve ground loop humming?

A: Using balanced power can help solve certain ground loop problems because it takes its ground from one source, thus having no potential difference.

You can do this yourself simply by taking all your power from one outlet or circuit. If your equipment “leaks” to the ground, meaning current is flowing to the ground wire, then balanced power might be helpful.

Some people believe that balanced power solves all ground loop problems, which is not the case. It is still possible to create ground loops with balanced power.

There are, however other problems that can be solved or improved by using balanced power.

In theory balanced power solves certain problems in a manner similar to how a balanced audio signal does, especially noise cancellation.

The typical claim made by manufacturers of balanced power equipment is that when power is balanced the main power cable has less electromagnetic field around it, so it should induce less noise to nearby audio cables.

Those claims are partially true. If you placed an unshielded cable next to a balanced power cable, quite a bit less noise/hum would be picked up. If you placed a shielded cable next to a balanced power cable less difference would result.

The capacitively coupled portion of the signal is intercepted nearly completely by the shield. Much of the inductively coupled component will reach the screened signal wire(s). Magnetic field around the cable will be practically the same whether the power cable is balanced or not, as there is still the same amount of current flowing up one wire & back down the other.

As always, we welcome input from the PSW community and would love to know your thoughts on balanced power. Feel free to let us know in the comments below!

BSS Audio Soundweb The Choice Kempinski Hotel

Luxury hotel builds first-class audio system around the London digital network.

The largest installation of a BSS Audio digital network in the Slovak Republic has been deployed with the opening of the new Kempinski Hotel River Park in Bratislava.

Located on the Danube River, the Kempinski will provide a new standard of lifestyle luxury in this historic city, steeped in imperial heritage.

With its selection of restaurants and bars, a spa and wellness center, in addition to a meeting room and four conference rooms (each divisible into two separate rooms), an advanced digital backbone connecting all the featured areas was required.

Peak Audio s.r.o. handled the installation utilizing two Soundweb London BLU-160 configurable processors, with two BLU-120 I/O expanders and a BLU-BOB2 break-out box, offering a further eight channels of analog audio output expansion.

The BSS Audio Soundweb London devices all interconnected through their digital audio bus.

Based on Gigabit Ethernet technology this bus carries 256 channels of fault-tolerant, low-latency audio at 48kHz/24bit, or 128 channels at 96kHz/24bit across a standard CAT5e connection — providing a highly cost-effective solution.

The Soundweb London matrix at the Kempinski is configured with 44 inputs and 20 outputs, providing signal routing to 13 zones (including the nine conference rooms, foyer and other areas).

Inputs are provided from a variety of sources including CDs, DVDs, wireless and wired microphones — and also notebooks in the conference rooms.

For local mixing with additional microphone inputs, a Soundcraft FX16ii has been provided.

Said Peak Audio’s Ján Krkoš, who project managed the installation, “The Soundweb London platform provided us with the perfect solution.”

“It was easy to program and create a custom control panel, which is straightforward to use. It provides high-quality audio processing and routing and can be relied on for 24/7 operation.”

Alcons Introduces BQ211 Carbon-Coned Subwoofer

The BQ211 is part of Alcons’ global dry-hire Ribbon Network inventory and comes with a 6 year limited warranty.

After sneak-previewed at Frankfurt 2010 as its European debut, Alcons Audio is now presenting its new BQ211 subwoofer, which extends the low frequency response of the company’s pro-ribbon systems for both permanent and portable applications.

It is the first introduction of the upcoming LR24 mid-sized pro-ribbon line-array touring system.

The BQ211 is a double-tuned, quarter-wave loaded subwoofer system which is designed to offer maximum, prolonged high impact SPL performance from a comparatively small footprint.

Featuring the very latest materials and design innovations, it contains a state-of-the-art very large displacement 21” Neodymium transducer with an all-carbon fibre cone, for high pressure loading, plus a force-ventilated 5.3” voice-coil.

The latter is mounted in a vented triple-spider frame and features optimised low resistance impedance and a port-vented magnet structure, to reduce power compression and prolong performance.

The internally-braced 15mm birch cabinet features double-tuned, high-pressure loading, through a rounded 236mm/9.3-in diameter low-tuned bass-reflex vent and wide, high-tuned quarter wave tunnel.

This provides optimised breathing at high SPLs, yet keeping the total system weight to a minimum.

Finished with Alcons Durotect flexible and scratch-resistant coating, it has slider feet on the bottom and sides, enabling the stacking of multiple BQ211’s into vertical low frequency arrays.

The additional front-positioned NL4 connector caters for easy “reverse connection” in cardioid arrays, enabling controlled directional LF dispersion.

It is powered and controlled by Alcons ALC series amplified loudspeaker controllers, whose SDP (Speaker Drive Processor) circuits offer BQ211-specific drive processing with response optimisation, dedicated power and excursion protection, hybrid filtering and cardioid processing.

Additionally, through the SIS (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BQ211 and ALC is completely compensated for, with a damping factor of 10.000, further increasing response accuracy.

With a frequency response of 33Hz - 150Hz (+/- 3dB) and an SPL that needs to be felt instead of read, the BQ211 is a wideband subwoofer with high SPL performance down to the lowest frequencies.

Measuring just 590 x 746 x 986mm (23.2 x 29.4 x 38.8-in.) and weighing just 72kg/159lb, it is a portable unit with an exceptionally small footprint.

Part of The Ribbon Network inventory - Alcons’ global dry-hire network - the BQ211 has a wide variety of uses and comes with a 6 year limited warranty.
