Lectrosonics Keeps Audio In Check At Emergency Operations Center

Lectrosonics Aspen processer central to unattended audio functionality

The Lee County Emergency Operations Center (EOC), located in Fort Myers, Florida, is the official county warning point for natural or man-made hazards such as hurricanes, water shortages, and wildfires that may threaten the area.

Lee County’s EOC is a state-of-the-art facility that makes extensive use of audiovisual equipment—and to ensure trouble free audio, the facility utilizes Lectrosonics’ Aspen audio processing technology.

Tampa, FL-based Encore Broadcast sales manager Douglas Taylor was responsible for working with the Lee County Emergency Management design team to develop a cost effective solution that met the requirements of the EOC.

Additionally, he was responsible for the sales, on-site installation, training, and the project’s continuing technical support program.

Recognizing the importance of an audio infrastructure capable of handling the EOC’s operations without requiring an on-site attendant, he deployed a Lectrosonics Aspen SPN1624 16 input / 24 output digital audio processor.

“For this facility, the Aspen processor handles automixing, level and muting control, some signal processing, and output matrixing,” Taylor reports. “The unit is installed in a dedicated AV equipment room outfitted with three racks necessary to hold all the equipment.

“As part of the unattended system functionality, the Aspen processor is interfaced with an AMX NI-4100 NetLinx Integrated Controller through a LAN/Ethernet connection.”

Having made use of numerous Lectrosonics AM- and DM- Series processors for many years, Taylor has been a long-time fan of the fundamental simplicity and versatility of Lectrosonics’ designs

“We selected the Aspen unit fully expecting the same level of positive experience we’ve had in the past with Lectrosonics equipment,”  he explained. “We were extremely pleased that the processor exceeded our expectations. The Lee County EOC is a mission critical operation, so we required equipment that is designed to operate in this type of environment. The Aspen processor delivered the goods.”

The Lee County EOC’s AV system went operational in July and, since that time, the Lectrosonics equipment has been performing well.

“Our client report that the new equipment is really helping them be more effective,” says Taylor. “The Aspen processor is another example of a well-thought-out Lectrosonics design. We look forward to the next opportunity to specify and install another Aspen system.”

Antwerp Zoo Upgrades Original Aquarium With One Systems

Part of the complete renovation of the Antwerp Aquarium included installation of new One Systems weather resistant sound reinforcement system.

The Antwerp Zoo, built in 1843 in Antwerp, Belgium, is the oldest animal park in Belgium, and one of the oldest in world.

Opened in 1911, the aquarium is located in a cave-like space under a Greek Temple in the southwestern corner of the zoo. Largely unchanged since it opened, the space had recently begun to show wear and tear due to the constant exposure to moisture and salt water.

As a result, the zoo embarked upon a complete renovation of the aquarium that included restoring the much of the stone and marble surfaces, replacing the rubber floor with an authentic stone floor and modernizing the tanks themselves.

As part of the project, the restoration committee decided it was also time to address the acoustic issues of the main visitor hall. The large rectangular room is roughly 130 x 55 feet and features an abundance of flat surfaces, marble archways and a 20-foot ceiling. Until now, no sound system was present.

With this new system the Zoo wants to create special effects for the visitor by playing 4 channel audio that will give the impression of sound rolling as a wave through the room. The Aquarium building will also be used for education and presentations.

Belgium-based COMMpunt bvba, a professional audio distributor that also provides design and integration support services, was hired to design and install, together with the electrical contractor, a new sound reinforcement system for the cavernous space.

“Between the size of the room and the hard, flat surfaces, we knew we needed a system that could provide controlled directivity but also withstand the humidity that comes with the aquarium environment,” explains ir. Michaël Rossignol, COMMpunt co-owner. “One Systems products came to mind immediately – they are completely weather proof and provide the audio quality and control the system required.”

Rossignol ultimately specified 13 pcs. of One Systems 106IM/100 loudspeakers, creating a distributed system that evenly covers the visitor viewing area with minimal overlap between zones. The loudspeakers, hung at 20-degree angles approximately 14 feet off the ground, are mounted with optional PT-10 bracket at the top of set-back archways that flank both sides of the hall. Complete coverage was ensured with placement of the enclosures in every other of the 26 archways. All loudspeakers and brackets were painted in the same color as the walls.

The One Systems 106IM was designed to provide high acoustic output, superb intelligibility and IP 56-rated direct-weather performance making them ideal for acoustic spaces like the aquarium. The 106IM design is unique in that it uti¬lizes a true compression driver coupled to a constant-directivity horn that provides a 100 degree horizontal by 70 degrees vertical coverage pattern.

The 106IM’s combination of the high-ef¬ficiency horn-loaded compression driver and an extra-large 1.75-inch (44.33 mm) voice coil design in the 6-inch (152 mm) woofer yields superior system intelligibility, vocal range in¬tegrity and added musical definition.

The aquarium system is powered by a Bosch 4-channel PLM-4P125 PLENA matrix amplifier which provides remote control and monitoring via the Plena Matrix app running on an iPad.  Mixing and routing is done with the new Apart Audiocontrol 12.8. The COMMpunt team also installed a Sennheiser XSW 35 Wireless microphone system utilized for custom tours and educational presentations.

“The visitor hall at the aquarium recently opened to rave reviews from the public and the renovation committee,” concludes Rossignol. “The audio quality and clarity is exceptional in the hall. Everyone is extremely pleased with the new system.”

Meeting Myriad Challenges: A Host Of Installed Microphone Solutions

Applications, technologies and techniques for a wide range of types and models

Many challenges in professional audio can be addressed with more than one solution. A good example is microphones – there are so many options and so many ways to deploy them.

Let’s take a look at a variety of mic solutions that have come to be considered “installed” in their nature, but the truth is that many of these products and solutions can produce great results in several sound reinforcement applications.

These are also called lectern or podium microphones, and have a small unidirectional condenser mic capsule on the end of a flexible boom about 6 to 18 inches long. A unidirectional polar pattern reduces pickup of room reverberation, feedback, and background noise.

The latest models are slim and elegant, and their boom arms adjust silently, unlike the creaky goosenecks of yesteryear.

The small mic capsule is sensitive to breath pops, but this can be eliminated with a foam pop filter and a high-pass filter set around 100 Hz.

Goosenecks tend to be popular boardrooms and council meetings, and an upside is that they’re less sensitive to paper-shuffling noises than surface-mounted mics.

Features to look for include redundant mic capsules; on/off switch, shock mount to prevent pickup of lectern thumps, high-pass filter to reduce thumps and breath pops, RFI suppression, interchangeable capsules with different polar patterns, mounting options, Atlas AD-11 flange, XLR connector, or desktop base.

Audio-Technica U85QL gooseneck microphone

Gooseneck Applications
Lecterns both installed and portable, church, boardrooms, council meetings, tele/videoconference, courtrooms, distance learning systems, talkback in studios

❚ AKG CS 2 and CS 5 conference systems, GN series, 99er, AMS, Architectural Series
❚ Audio-Technica AT808G, ES905CL, ES915C, ES915SC, ES935C6
❚ Audix ADX12/18, MG Series, Micropod
❚ beyerdynamic MCS 20, MSC 50
❚ CAD (Astatic) GM10VP variable pattern
❚ Countryman ISOMAX 4RF
❚ Earthworks FM and FMR Series
❚ Electro-Voice PolarChoice podium and desktop
❚ Shure MX405, MX410, MX412, MX418

Small, inconspicuous boundary mics with a cardioid or supercardioid polar pattern. As their name indicates, these sit on top of tables and pick up the voices of people speaking. Inside the mic housing, a tiny directional mic capsule aims horizontally across the surface.

Because the mic capsule is small and lies on the surface, it picks up table sound reflections in-phase with the direct sound from the source. This prevents comb filtering caused by phase interference between the direct and reflected sound waves.

Shure MX392 tabletop microphone

The unidirectional polar pattern reduces pickup of room reverberation, feedback and background noise. Some models are miniaturized - about 1 inch long. Others are about 1/2-inch in diameter with omnidirectional pickup pattern, and these can be flush-mounted in the tabletop, resulting in a clean appearance.

A few models have interchangeable capsules with different polar patterns. It’s common to use multiple mics on a conference table, either one mic per person or one mic between every two people, about an arm’s length away.

These can all be run with an automatic (gated) mixer, which turns off all mics except the one in use, which reduces the number of open microphones, resulting in a clearer sound with less feedback.

Examples of automatic mixers include the AKG DMM 4/2/2, Shure SCM800 and SCM410, Dan Dugan Sound D-2 and E-1.

Yamaha also now offers the Dugan-MY16 card, which facilitates automatic mic mixing in current model Yamaha digital mixers and processors.

Lacking an automated mixer, mics that have built-in press-to-talk switches can be used. One innovative product is the Revoluto Microphone Array used in several beyerdynamic conference mic systems.

A group of mic capsules are wired together to create an array that provides the close-up sound of a gooseneck mic, but in a low-profile chassis.

Some recent models are also wireless.

Tabletop Applications
Boardrooms, conferences, governmental body meetings (city councils, etc., tele/videoconference, courtroom, altar table in houses of worship, distance learning systems

❚ AKG C 547 BL
❚ Audio-Technica ES947, ES961, ES963 (multidirectional), Pro 44, U851R, U891RWx
❚ Audix ADX60
❚ beyerdynamic MCS wireless digital system, wired MCS system, Revoluto system
❚ CAD (Astatic) 2220VP, 930VPL variable pattern mics, 901R, 201R.
❚ Crown (AKG) MB3, MB4, PCC-170, PCC-170SW.
❚ Electro-Voice PC boundary mics (polar choice), PC boundary sat mic, RE90B
❚ Sennheiser WICOS wireless conference systems, SDC 8200 desktop goosenecks, infrared conference systems
❚ Shure MX391, MX392, MX393, MX690 wireless
❚ Shure MX405, MX410, MX412, MX418

Rugged, unidirectional boundary mics typically used on a stage floor to pick up actors in drama or musicals. Like a tabletop mic, it uses a tiny directional mic capsule on a surface to prevent the comb filtering from phase interference.

The frequency response is tailored for intelligibility, typically with a small high-frequency rise and low-frequency rolloff. The polar pattern is cardioid or supercardioid to reduce the potential for feedback and to minimize pickup of room acoustics.

Crown Audio PCC-160 boundary microphone

Some models have a permanently attached cable for extra ruggedness – a good idea if the mic’s tiny XLR connector is likely to be stepped on.

Usually one to four stage floor mics, placed a few feet from the front edge of the stage, will do the trick.

General Guidelines
20 ft stage: 1 mic center stage
25-30 ft stage: 2 mics 12 to 15 feet apart
35-40 ft stage: 3 mics 15 feet apart
45-50 ft stage: 3 mics 17 feet apart

Because a floor mic is far from the sound source, feedback can be an issue. If this happens, place the loudspeakers closer to the audience than to the mics.

—You might want to delay the signal going to the loudspeakers so that the audience will localize the sound on stage.
—Use a feedback suppressor (such as the Sabine FBX1200) between the mixing console and the power amplifier, or use a 1/3-octave graphic equalizer between the mixing console and the power amplifier. Turn down frequencies that feed back by no more than 3 dB if possible.
—Place the mics as close to the actors as possible without getting in their way.
—Do not use compression.
—Train actors/people speaking to project - the microphones need something to pick up.

Boundary Applications
Theater stage plays and musicals, choirs, dance troupes

❚ Crown Audio PCC-160 (marketed by AKG)
❚ Bartlett TM-125, TM-125C
❚ DPA BLM4060

These inconspicuous mics are designed to mount in a wall or other surfaces, acting as a boundary mic. Some models are disguised as light switches; some are tiny disks, and some are weather resistant for use outdoors.

A security mic also can be used to sense ambient sound levels.

AKG C 562 CM miniature boundary microphone

The mic signal controls the gain of a PA system, turning up the amplified sound to prevent masking whenever ambient levels increase.

While most models have a mic-level output, some produce a line-level signal for direct connection to a recording device’s line input.

Security/Surveillance Applications
Building entrances, transportation stations, surveillance, recording meetings, interrogations, warehouses, schools

❚ AKG C 562CM
❚ CAD (Astatic) WM-625, 210, WM-1000, 202RW
❚ Crown Audio PZM-11, PZM11LL, PZM-11LLWR, PZM-10

Miniature condenser mics that clip onto clothing about 8 inches under the chin (or in the hair), allowing the talker freedom of movement.

Lavs have a tailored or contoured frequency response.

The high-end rises to compensate for the mic being off-axis to the mouth, where high frequencies are weak.

Sound diffraction of the body tends to cause a peak in the frequency response around 730 Hz, so some models include a dip filter at that frequency. The result is a more natural sound. It’s common to clip-on two of these mics for redundancy in critical applications.

Most models have an omnidirectional polar pattern. The advantages are less clothing noise, less wind noise, and more consistent sound levels when talkers turn their head.

Audix L5 lavalier microphone

Cardioid models are recommended when background noise or feedback are severe.

Some models are designed for use with wireless mic transmitters, and are equipped with mini-connector that mates with the transmitter’s mic connector.

Lavalier Applications
Church, broadcast, wandering lecturers, theatrical productions

❚ Audio-Technica AT803, AT831R, AT899, BP896 MicroPoint
❚ Audix L5
❚ Countryman B3, B6
❚ DPA 4060 and numerous variations
❚ Electro-Voice RE90Tx, RE90L
❚ Shure MC50B, MC51B, MX 183, SM93, WL183, WL93
❚ Sennheiser MKE Platinum-4-C, MKE 2 Gold
❚ Sony EM77B

As the name implies, these small mics are worn on the head, so the user is free to move around while talking. A wire or plastic frame goes around the ear, and sometimes around the back of the head. A slim boom holds the microphone close to the edge of the mouth.

Because the mic is so close to the sound source, gain-before-feedback is excellent – even with omnidirectional models. It’s nearly invisible in use.

Sennheiser HSP2 headworn microphone

Several models are designed to work with beltpack wireless mic transmitters.

At the end of the mic cable, a miniature connector mates with the mic connector in the transmitter.

Headworn Applications
Worship, lecturers, presenters, actors, singers, health club (aerobics and yoga instructors)

❚ Audio-Technica ATM73a, ATM75, BP892 MicroSet
❚ Countryman E6 and E2 Earset
❚ DPA d:fine
❚ Electro-Voice RE97Tx and RE97-2Tx
❚ Sennheiser HSP 2, HS 2, Ear Set 4, Ear Set 1

Small, unidirectional condenser mic capsules at the end of long cables, typically hung near a choir or actors upstage. The mic cable usually carries a mediumimpedance unbalanced signal from the mic capsule.

At the end of the cable is an XLR connector or small chassis. Inside the connector or chassis, a circuit provides a low-impedance balanced output and converts phantom power into DC bias for the microphone capsule.

Electro-Voice RE90H hanging microphone

The polar pattern is cardioid, supercardioid or hypercardioid to reduce feedback, and the frequency response has a small rise at high frequencies to compensate for being off-axis to the mouth.

Generally, use one microphone in the center of every 20- to 30-foot span of singers. A choir of 30 to 45 voices should need only two or three mics. Place them about 18 inches in front of the first row of singers and about 18 inches above the head height of the back row.

The mics are raised so that the front row is not too loud relative to the back row. Run a fishline between side walls to anchor the mics so they don’t rotate.

If it’s inconvenient to hang choir mics, consider using mics mounted to thin carbon-fiber booms on mic stands, such as the Audix Micro- Boom, AKG GN155 CHOIR boom stand, CAD (Astatic) 2700VP or 1700VP. The latter models have continuously variable polar patterns.

Although hanging mics can be used for overhead pickup of a conference, this application is not recommended. The mics are usually too far from the talkers, and the resulting sound tends to be muddy and noisy with poor gain-before-feedback.

Choir/Hanging Applications
Choirs, actors who are upstage, security-surveillance

❚ AKG CMM 99, HM 1000 hanging module with CK capsules
❚ Audio-Technica ES933C, ES933H, U853 Series
❚ Audix ADX40
❚ Countryman Isomax 2
❚ Earthworks C30/C
❚ Electro-Voice RE90H and RE92H
❚ Shure MX202

Hob Sound Adds Soundcraft Si Expression To Its One-Man Show

Owner Rob Bernstein requires a versatile console to match his needs

Rob Bernstein, the sole owner of Hob Sound in Framingham, MA, recently purchased a Soundcraft Si Expression 2 to accommodate his production and mixing needs.

As a one-man business that provides sound equipment for a wide range of events, Bernstein requires a versatile console to match his needs. In addition to recallable features and analog-type controls, the Si Expression Series comes with GEQ effects on every bus as well as built-in Lexicon effects.

Within 15 minutes of working with the Si Expression, Bernstein was impressed with the console. “Its versatility blows anything else out of the water,” he says. “Having the graphic EQs available to all the buses is a huge advantage, and combined with the availability of compressors on each channel, this console replaces a lot of gear. This is critical to my operation, since I cannot haul all those additional racks by myself.”

The console’s ‘1 Control = 1 Function’ ensures that there is never any layering of controls. The One Touch Easy Mix (TOTEM) allows a single key to mix to an AUX, FX or Matrix bus. The Si Expression also imcludes FaderGlow color-coded illuminated faders and a range of connectivity and network cards.

“I love how much faster it is to set up for an event, due to the recallable features,” Bernstein adds. “Even though this is my first digital board, it retains the simple feel and authentic sound of an analog board that I have grown accustomed to in my decades of experience. Also, I no longer have to worry about choosing which channel gets compressed or gated.”

Hob Sound recently mixed a show with the local band The Fools in the Boston area, with Bernstein reporting, “The Si Expression sounded great, and it is everything that I need from a console.”

The console was purchased through Pro Audio Star, based in Brooklyn, NY.

Sri Lankan Adult Education Centre Refits With QSC

KLA & K Series Speakers Used in Main Auditorium & Lecture Halls at the SLFI

Sri Lankan QSC distributor Dynamic AV technologies has installed QSC Audio KLA and K Series loudspeakers in a refurbishment of the auditoriums at the Columbo-based Sri Lankan Foundation Institute (SLFI).

The Institute is one of the Sri Lankan Republic’s largest and oldest adult education centers.

The SLFI, which celebrates its 40th anniversary in 2014, specializes in vocational training for the Sri Lankan people in a variety of career disciplines, including psychology, sociology, business and language studies.

The sound reinforcement systems in the Institute’s main auditorium and four associated smaller lecture halls were all recently refurbished, receiving new loudspeakers, microphones, and sound mixers.

Dynamic AV Technologies suggested QSC KLA and K series loudspeakers for the PA systems. The main auditorium was the recipient of four QSC KLA12 line array units (two per channel) with a pair of KLA181 subwoofers, and a further pair of K8 Actives acting as sidefills.

A new mixer and wireless Lavalier microphones for use by lecturers completed the upgrade. The four lecture halls each received a portable PA system comprising a pair of QSC K8 loudspeakers supplemented with a compact sound mixer and wireless mics.

Commenting on the performance of the QSC KLA and K Series following the installation, the management of the Sri Lanka Foundation have professed itself very happy with the sound quality of the QSC system, after searching for some time to ensure that the quality of the PA system would be sufficiently high.

The management was persuaded to choose QSC after noticing that QSC systems have been used in many Sri Lankan government installations.

Tech Tip Of The Day: DIY Balancing Of Unbalanced Lines

A way to pseudo-balance an unbalanced line in a pinch?
Provided by Sweetwater.

Q: Recently I was working a live show and needed to get an unbalanced signal from point A to point B. Given the noise that was induced in running the unbalanced line that distance, it was obvious we needed to balance the signal.

However, of course, we had an awfully limited kit (this was a really inconsequential and tiny show) and we didn’t have any balancing transformers available.

I’m sure there’s a way to pseudo-balance a line in an emergency, but how do you do it?

A: Nice question!

Let’s say you needed to run a signal from a keyboard to your mixer. Obviously, in your case, the unbalanced line was quite noisy, and you didn’t have the requisite balancing transformer.

What to do?

It’s not hard to make a pseudo-balanced line from the unbalanced output of the keyboard. Basically, you make the run with a standard balanced cable (TRS or XLR).

For an XLR cable, at the end where the cable plugs into the keyboard connect a precision potentiometer to pin 3 (cold, or “-”) and to ground/shield (pin 1).

On a TRS this would be between ring and sleeve. Connect pin 2 hot, or “+” as normal. On a TRS this would be the tip.

Turn the equipment on and turn up the gain on your mixer until you hear a good amount of hum and line noise coming in from the keyboard line.

Turn the potentiometer (which will change the resistance between “-” and ground) and you will hear the hum and noise level change. With some careful work you should be able to find a “sweet spot” where the hum is minimized.

If this were a permanent installation you could then measure the resistance of the pot at that setting and substitute a precision resistor in place of the pot.

What you have done is put a resistance in parallel with the output impedance of your source (in this case a keyboard) from “-” to ground that matches the “+” relationship.

Normally, on an unbalanced line, “-” would be shorted to ground, and you give up any CMRR (Common Mode Rejection Ratio) your mixer’s balanced input has.

Although not a perfect substitute in all instances, we’ve heard this make a dramatic difference in certain circumstances.

Remember, you must use precision components here, as minute changes in value will significantly effect the signal-to-noise ratio.

Riedel Sponsoring Innovative Monash University Formula SAE Team

Spotters, engineers, and drivers communicate with one another to ensure safe and effective testing and racing

Riedel Communications is sponsoring Monash Motorsport (MMS), a team of students from Australia’s Monash University that each year designs, builds, tests, and races an open-wheeled formula-style racecar in the renowned Formula SAE (FSAE) series.

Using two-way Motorola radios and headsets supplied by Riedel, MMS team spotters, engineers, and drivers communicate with one another to ensure safe and effective testing and racing of the team car.

“The radios provided by Riedel have been fantastic, and the reception is clear and crisp,” said Areeb Hassan, business team leader and suspension engineer for MMS. “We haven’t had a single issue with the gear and have had no need to contact Riedel for support, but the company has been very helpful and accommodating.

“We look forward to expanding our use of the communications system to enable the reception of valuable live telemetry data from the car and for competition updates during the Endurance Event.”

MMS competes in the FSAE design competition, which includes more than 500 universities from around the world. The team is currently ranked No. 2 in the world and has won the FSAE Australasia Competition for the past four years.

Having completed their latest car, the M13, the team has been testing and validating their design in preparation for the Australasia competition in December as well as a series of high-profile races in the U.K. and Germany in 2014. MMS was an early pioneer of the use of aerodynamics in FSAE, with its 2002 car being one of the first cars in the competition to feature wings.

The M13 has been designed with a much more aggressive aerodynamics package, boasting some of the largest front and rear wings in the competition, as well as the use of an undertray. The team designed the M13 using CFD modeling and has physically validated it in the Monash Wind Tunnel, also located at Monash University in Melbourne.

“The MMS team is an innovative and inspiring group of students that has achieved remarkable results in the FSAE Series, and it’s a pleasure to support their efforts by providing the reliable, high-quality communications equipment so critical in live test and race environments,” says Cameron O’Neill, solutions manager at Riedel Communications. “We wish MMS the best of luck as the team takes its new M13 car into global competition.”

EAW’s Anya Makes Korea Debut, Takes Center Stage On Cho Yong-Pil Tour

RhinoSound chooses Anya to support Korea's top musical artist

Before it joins the hottest concert tour in Asia, Korean distributor Dasan SR’s newly acquired EAW Anya system made its debut in Korea and participated in loudspeaker “shoot-outs” at the recent KoSound+Stagetech 2013 show.

“We’ve had a lot of comments from people at the show about Anya’s incredible, studio monitor-like fidelity and that she simply sounds amazing,” states Davwinder Sheena, Asia-Pacific managing director for EAW.

Fresh off that competition, the same system will hit the road on Cho Yong-Pil’s 50-city “Hello” tour currently in progress in Korea and Japan. Yong-pil is Korea’s most enduring pop star. His 19th album, “Hello,” knocked Psy off of the number 1 spot for Korean album sales.

SunMo Kang, Dasan SR president, explains why RhinoSound chose Anya for this tour: “The most important reason is Anya’s Adaptive Performance technology. RhinoSound has many years of experience with mega-size stadium concert tours, and the engineers have fallen in love with the Anya system. They can program its multi-direction sound to cover all levels, from the ground floor to the second and third levels and on. It saves an enormous amount of time for FOH engineers, and gives them full mixing satisfaction.

“It serves not only the most powerful but also the most luxurious sound performance possible,” Kang adds. “We sincerely believe Anya will begin a new trend in live sound.”
