	The 3060 came out right after I invested in a DBX 166x. I took one
to the club I was working at at the time and tried it out, and I have to
say, at 1/2 the price of the 166x, it is an excellant bargain. While
auto attack and release are ok features, I like control of attack and
release as it makes the compressor more flexible. If you're mainly
looking to use it on vocals, this is not as necessary. A friend of mine
has a couple of 3060's ion his studio, and also likes them a lot, so I
guess they are quiet enough.
	One other unit you might want to check out is the BSS compressor
that has 4 units in a 1u rack. They don't have gates, but they do have
an excellant frequency adjustable de-esser. I can't remember th model
number, but I have used the older, 2 per 1u version, and it was
excellant for vocals. If imprperly adjusted, the de-esser was noisy, but
it was very nice for removing annoying sibilance from vocals. The new
unit appearantly has the auto circuitry, where the old one allowed
attack and release adjustment.

All the above is good sense but this specific job was negoiated in

that there was the two of us and a room full of head bangers.  I was
unwilling to risk any other damage to equipment or person by pissing

It is a breath screen.  Much less destrictive to the sound then a foam
type.  I also use it to keep the performer at the right distamce from
the mic.

The first incarnations of this breath screen was done using a womans

I recently purchased both the Alesis 3630 and the Valley Dynamite2 for my home
studio. The Alesis IS a good bang for the buck ($240), but the Dynamite2 is a
better piece ($400+). I found the gate on the Alesis to be moderately useful. 
Its OK for eliminating low level background noise, but with a -10db max threshold
point, its pretty useless on isolating drums. The Valley goes up to +10db on its
gate and I can get a nice clean kick drum track with no snare/tom bleed on it.

Mostly I've used the Alesis for smoothing backing vocals during mixdown and to 
get a little better S/N onto tape for guitars when tracking (if the Dynamnite2
is already full).

I'm impressed enough with the Valley stuff, that a Gatex and another Dynamite2
(or 2) are moving up my wish list... Check them out. You can buy factory direct
or from mail order houses. Not too many retail places seem to carry them.

Bypassed or not, the zener will contribute the most noise in the circuit
due to avalanche breakdown. You can get far lower noise in any of a number of
ways.

You could replace the zener with a number of forward-biased diodes (any
kind).

You could replace the zener with a resistive voltage divider.

Or you could use a bandgap reference (AD makes some of these) and
multiply it up with an op amp.

   The amplifier is clipping INTO THAT SPEAKER LOAD....whose fault

   Usually an overdriven speaker becomes audible when the bass is
   overdriven....this is usually a truly horrid mechanical rattling
   sound.  Some rare wimpy midranges (and some verrrrrry pricey
   panel speakers) will exhibit signs of overdriving in the
   midrange.  On a cone speaker, overdriven midrange tends to be
   brassy, harsh (usually...your mileage may vary) or even honky.

   An overdriven tweeter USUALLY becomes very silent very fast.

   An overdriven electrostatic usually sounds very much like $$$$
   going up in smoke...for good reason.

   An overdriven amp will tend to start sounding very harsh....much
   like a J. Hendrix rock guitar sound.

    Did the amp clip, or did the Polks start making rattling noises?
    It also could be defective power supply in the amp......

    If the amp, check for excessive bass boost or bass
    boost+loudness control on.  Its pretty common to boost the bass
    too much on a pair of small speakers to make it sound better.

There is a circuit that uses an op-amp.  I will try to describe
a current source (well, actually a sink).

Connect the source of a power mosfet through a resistor to minus V.
Also connect the source of the mosfet to the inverting input of an
op-amp.  Connect the output of the op-amp to the gate of the mosfet.
Apply a reference voltage to the plus input of the op-amp that is 
referenced to minus V and bypassed to minus V.  The opamp output
will go to the voltage required to drive the source of the mosfet
equal to the reference voltage.  The drain current of the mosfet is
then V reference over the resistor value.

This method mitigates the effect of the equivalent input voltage noise
of the mosfet.  The equivalent input current noise of a mosfet is very small.
The equivalent input voltage noise of the op-amp remains, but if 
the voltage across the resistor is at least two volts, it will have
only a small effect on the output current noise.

A Ph.D. thesis from Stanford explains this circuit more fully.
I can find the exact reference if you want it.

Summary: A few questions about my new Yamaha RX-V850 receiver
Keywords: yamaha rxv850 question help audio video surround prologic

I just took delivery of my new Yamaha RX-V850 (and Sony MDP-455 LD
player, Aiwa 810 cassette deck, neither of which are hooked up yet :)
from J&R Music World last nite, and have a few questions on the
receiver.  

So far, my system consists of the above components, plus a nice
VHS (oxymoron?) hifi VCR, eq/analyzer, Definitive DR-7's in front
and Minimus-7's in the rear.  Sound quality is great (the DR-7's
are amazing!).


1) I have an outboard eq/spectrum analyzer between the pre-out/main-in
   couplers on the receiver (for the disco lights :) -- the signal is
   indeed passing through the eq (if I turn the eq off, the receiver goes
   quiet), but the analyzer remains dark (it does work!).  Could the 
   Yamaha be passing an extremely low signal or something?  (adjusting
   the volume on the receiver seemed to have no effect)

2) I tried to cheat on the center channel--by hooking the center pre-amp
   output to an old boombox, but the signal from the boombox is VERY low.
   I have never had this problem hooking other components to this boombox
   through line level inputs.

3) The signal from the rear (Minimus-7's) is also a bit low.  I have
   to turn the surround channel volume up to ~94-96% for acceptable
   results.  I haven't been able to find any sensitivity numbers on
   the Minimus-7's--could it be that low??

Any help appreciated!

Thanks!

Again a big hearty thanx to everyone who's helping me on this... ya
just can't learn this stuff in school it seems... (it's much too
practical)...

Anyway,  could someone tell me where in a power supply design the
amout of output current get determined?  I understand the
transformer determines the voltage, diodes do the rectification and
capacitors/inductors will handle the filtering (leaving the
regulation for some lucky IC!) - but I don't see where the output
current is determined (V=IR somewhere I assume).  Is this equation
true: Volts@primary supply x Amps@primary supply = Volts@other side
of the transformer x Amps@other side of transformer x efficiency of
transformer?

Also (I swear this has something to do w/audio!) can I send my
subwoofer amplifier more than 12V in a quest to give it 15amps or
so?  

Finally, what is the current that comes out of a wall socket? I
see it's 110VAC @ 60Hz, fine, but what's the current?
But, does the amount of current not matter because the line current is
isolated from the output current by the transformer?  Is 110volts
pulsating 60x/sec. all that's important to the transformer/rest of
the power supply?

Hello Folks,
   Does anyone have experience with the Pioneer "Auto BLE" type decks?
I was looking at them over the weekend and the idea seems good to me.
The deck records a test signal on the tape and then reads it off again to
set the bias level for the individual tape in use.  I'm not a fan of gee-whiz
gadgets but this actually aeems useful.  
  The particular models I was looking at were the CT-S410R and the CT-S601.
I think those are the right model numbers.  One has 'quick' auto-reverse 
while the other has selectable equalization curves.  Anyone have opinions,
preferably backed by experience?  Thanks.
