The place to start would be the Steve Dove material. It's still in publication, as a chapter in the "Handbook for Sound Engineers", edited by Ballou, published by Focal. As for mixing consoles, you should see what schematics you can compile...some companies have made them available on the web. A cou...

-3 db at 200 Hz is a fault seldom found with anything besides a a skanky mic imported from China. Ok, but why? Is it 'coz the transormers are made out of a crappy metal? Is it 'coz of poor wiring? Poor soldering? Que pasa? Crummy transformers, crummy coupling caps. Not to mention that the capsule a...

I can think of three examples where this might happen (but more often as screwing up the extremes of the spectrum, not spikes or dips at specific frequencies): 1 - DC coupling caps that are too small rolling off lows and imparting phase shift in the audible band. More commonly seen on cheap guitar p...

Give Mouser.com a try. Use their PDF catalog, and look for Alpha and Bourns pots, see of anything looks about right. As for the taper, it could be log, linear or even reverse-log. If the old one is at least somewhat functional, you can take it out and measure it. If it's not, the Alpha pots are chea...

The type of output that's OK with grounding the cold line is sometimes called "ground compensated" or "cross coupled." "Impedance balanced" will be OK with it, too...and looking at the manual (thankfully on the Peavey website), that's what they are...AKA "Z-balanced." Alternatively, you could use th...

ckeene, Have you seen the Speck LiLo? It's close to what you mention. Knights, I have looked into building my own, and the cost added up very quickly. I was looking at designing to a decent standard: 24 channels with Edcor transformers on all IO, transistor amplifiers, inductive EQs, Alps faders and...

First, what is the device with the balanced output that you're trying to unbalance? That recommended scheme only works for some types of balanced output circuit. You might have to check the manual to determine the right way to unbalance it. (for reference, I know the Distressor uses the circuit that...

From my cursory reading, it looks like brushless DC motors don't want to be controlled by a variable AC voltage. They want to see the rated voltage, or nothing at all. So if you don't need super precise control, you can use PWM to turn it on for an instant, then turn it off for another instant, then...

Impossible? No. But simple, not really...unless you can find something off-the-shelf, like a suitable fan with a temperature sensor built in, like some PC fans. A quick web search tells me that you can control a brushless motor using a pulse-width modulation signal (PWM), or a specialized brushless ...

You PC sounds a lot like one of my old ones...a P3 overclocked to 866, with (I can't remember) either 384 or 768 MB RAM. It was able to handle 24 track recording and playback without a problem (of 24 bit, 44.1 KHz files). It did have fairly fast (by the standards of the day) dedicated SCSI drives, a...

I had dinner with a former coworker last night, another storage-savvy person, and we discussed some strategies that might be good for you. There are a couple of guiding principles in tiered storage like this: -once a piece of media is no longer active (a disc burned, a tape or hard drive shelved), t...

I've got a background in heavy-duty storage. Fortune-100 companies have faced the same problems, and deployed big-gun technology to deal with it. The common setup is called a "Storage Area Network" or SAN. A common deployment for what you're talking about would use drive arrays (RAID or JBOD) for "m...
