Re: Power / Volt regulating question for touring musician
| Nick Cormier wrote on Tue, 09 February 2010 10:52 |
What if I got a simple line conditioner (to clear up noise) for my guitar rig, and then used one of those UPS voltage regulating "blocks" behind that to make sure if I am playing somewhere that my voltage stays consistant.
|
Do you have noise now that you can attribute to the AC line?
Has anyone ever demonstrated a product to you that cleans up that noise (if it exists) in an A/B test?
Personally, I'm quite skeptical of these "power conditioner" claims, and wouldn't spend the money on one unless I could answer "yes" to both questions.
Having said that, I have had some good experience with double conversion UPS units. We had a noise problem with certain powered monitors (ironically caused by a building UPS), that was cleaned up completely by running the monitors off a double-conversion UPS. The usual cheap UPS units won't work, because they only switch on-line when the power fails. They don't even regulate the voltage unless the line fails (falls outside some predetermined limits).

EAW SB850 Question
A friend of mine has a question about some EAW SB850 Subs...How are people generally running these with 2 per side (4 total) if your using a crest 9001 or MA5002VZ amp? Will you be able to successfully run 4 of these subs with 2 of these amps, or will you need 4?
Are you running the amps bridged and linking the two subs? If the subs are linked, does this mean they are dropped to a 2 ohm load? I know the EAW specs say that running the subs off one amp is a 4 ohm load, but running the subs from 2 amps is an 8 ohm load.
I hope my question is specific enough, or that I'm asking the right thing! Thanks in advance for any info or suggestions.

Going from full space to half space is a 6dB gain, isn't it?

It depends.

Re: Help marketing high efficiency rigs against high "wattage" competitors
Don't let the competition set the rules. You offer a service, not a truck full of black boxes. Sell that service. If it is defined by the hardware you are always just a day away from being aced out by the next player with a bigger truck full of gear. You want your customers to DEPEND on you for their livelihoods. When you frame it in those terms you win every time.

| RYAN LOUDMUSIC JENKINS wrote on Mon, 01 February 2010 12:49 | You could always do what the guys around here do. One guy has 8 SR728X and 4 SR725X and he tells everyone that he has 28 speakers. He gets work and charges too little but it is what it is. Pictures often work better than words.
Take a couple really nice shots of your gear and create a small brochure and a three ring binder full of picture that you can show of different configurations.
I like to use the phrase "Properly Powered for Optimum Performance!" We use different amps for the same speakers in different situations so it doesn't really matter how much power you have as long as it is optimum for the particular event.
|
I originally wanted an SRX rig, but really couldn't put something together that would perform within my client's budgets once amps and a distro were factored in, and a distro hookup would be impossible or cost prohibitive for a number of my events.
My goal was to strike a balance with the power requirements, cost, and quality. I agree I should play up quality more than quantity, but I still face customers asking "So and so has a 10,000 watt system good for 1,500 people.. what can yours do?" or "how many tops and subs do you have".
I do plan on putting something together with photos and other info and the more I think about it I'll probably throw a little graph on comparing the output to a less efficient speaker and explaining the benefits of lower power requirements (especially when combined with my LED lighting).
Thanks for the guidance so far and if anyone has any other ideas or has seen a succinct explanation of efficiency vs power is speaker systems do share.

I run a small SRX rig. All Xti amps, I use two breakers.
All of my bookings go like this.
"Tom, are you booked on (insert date here)?
No? Cool, see you there."
My business my be a little different than yours. I do weekend warriors, tribute bands, cover bands, and regionals.
No one ask how many watts ...13kw give or take.
They just want to know if I'll be there.
Maybe it's a matter of selling yourself?

Our current president snubbed the Dali Lama once already. He said recently he will meet with him. At the moment the Chinese are ticked off because we sold some military hardware to Taiwan, which China still considers part of their country, and not a sovereign nation.
A lot of this is Chinese posturing to save face at home. They shut down military communications between our two armies, over the sales to Taiwan. Hopefully this too will pass.
Primary tension between us is over valuation of their currency, while it should be over human rights. Meeting with the Dali Lama is just symbolic, but would be a better message than we sent in the past by snubbing him. IMO

Re: CD Burner/Player Product suggestion
A Mac Mini comes to mind. Of course you would have to buy your own rack shelf.
Of course while what you describe would be a great idea for our niche market it ain't gonna happen. Low cost means high volume and the pro sound industry is not that.

Re: crown ma5000vz trouble
IF (that's a fairly big IF) that power supply is similar to the Crest 8001, it has a step start circuit to minimize inrush current. I repaired a 8001 years ago that had a shorted diode in one of the bridge rectifiers, but it only kicked in at the second step.
I haven't been inside the Crowns, but any competent bench tech should be able to figure out where the problem is, and fix it, if replacement parts are still available. I should stress the competent part, because there are potentially lethal voltages in there, and you can do some arc welding if you drop a screw driver in the wrong place.

Re: Can U Really Make a living in Audio?

Degree first, when you're young. Otherwise, you may find yourself with a wife, kid, mortgage and the need for a steady job and the need for that degree. I've seen a lot of fine technicians who just never went to school, because of ..... they get the short stick. Engineers are taught how things work and how to find out how things work. You can learn the practical side from a job. When we hire the bright young minds fresh out of school, it's about 2 years before they know enough to work on their own. They take a lot of supervision at first. But we expect them to have the background to learn the practical details of the job. Frankly, trade schools are not work much IMO. Having a trade, like becoming a journeyman electrician, is worth a lot. The key is to have your background and education transportable to a variety of situations. A EE/Physics graduate qualifies for a wide variety of jobs, an electrician qualifies for a wide variety of jobs. You future may bring a variety of experiences, needs and wants. Every industry contains a pyramid of earners. Find something you like to do and DO it well. Whatever you pick, you will be doing a lot of it. It should at least be interesting and fun.

I second the wife, kids, mortgage syndrome.
I graduated HS in 77. My dad was a dealership mechanic for a Ford dealer. Not much money in the pool for college, and there were 3 more mouths to feed behind me. I did the military thing to get some education and real world experience.
Some say the military teaches you a work ethic. I wasn't impressed. I've spent numerous nights in a garage getting a car ready for a client with dad. I understood a work ethic, that's how we were raised. But Uncle Sam offers schooling. With 4 years of work, technical training, and a few book classes it was easy to get an AS in applied sciences. That's enough to crack open a door.
I got out of the military, took a job, and went back to school. Somewhere between school and having fun I got married and started a family. School started to take a back seat. Then I started working at a college. At IU, Purdue, or the University of Chicago working for the institution also meant 1/2 price classes, and free audits.
Though never published, I am educated despite having a family. What saved me was my workplace was also where I could get an education.

Re: The Who - Best Super Bowl performance ever!

I just can't help it. I saw The Who in 1976 at the Silver Dome for what was for many years the largest indoor Rock & Roll show in history.
Over 80k paid if I remember right.
Back then I was into DIY home audio and had no clue what was going on.
But in the end it did not matter then or now. I have liked The Who since Live at Leeds and Woodstock. Nothing they do is going to change that. I understand all the performance problems, but when the play a song I still hear it (in some way) like I did back then.
As for not being into what they were doing, hogwash!
I still remember them playing right after 9-11. Pete thanked America for allowing to be part of what was one of the most painful moments in our country's history.
And that show was not perfect either.
Now don't get me wrong, I am not flaming the people that are criticizing the performance, but there is a whole other side of history involved here and it is the reason they were asked to do this.
