I have used a router to cut circles for woofers (and the indent for
front mounted woofers).  There is a fixture for the router to cut circles.
What I did, however, was to use the fixture (available at most hardwares)
to cut a template out of masonite having the correct size circle, then
used that template to follow with the router to cut the circle in the
particle board (I used 3/4 " high density particle board - to cut that with
a router you need to use a carbide tipped cutter).

Best to practice on a piece of scrap first.

Hope this helps.

I am thinking of buying a set of Cambridge Ensemble II Speakers
(the one with only one subwoofer). I recently received their
catalog and was about to order when someone in this newsgroup
mention something about getting a coupon if I wait a couple

or II or both and if it is good for II, how much of a savings
is it? Any help would be greatly appreciated. Please contact

Aren't PNP transistors a good bit slower than NPN?  Would that make
class-A amps w/PNP's exhibit more slewing-induced distortion which
might mimic the SID of old tube amps?  Of course, this all assumes
the amp is not terribly well designed to begin with.

My own opinion is that amplifiers made with complementary pair
outputs sound just fine.

I came close to getting the 545 and the 500-II until I heard Acurus.  I haven't
been able to listen to the Acurus A250 & L10 next to the Adcom, so I'm not sure
how to go about making the choice short of ordering both and sending one

I realize this is an FAQ, but does anyone have a recommendation for
buying a portable CD player?  I lean towards one that can be used in a
car as well, but that's not necessary.  My last one (a Panasonic)
broke upon a fall.

More specifically, I have a catalog that lists the Sony CarDiscman
(with cassette adapter, "anti-shock" mechanism, and lighted controls)
for $189.  Is this a good price?  Should I go for it?

I appreciate any replies and the time that went into them.

Organization: OUC, University of Notre Dame
Date: Tue, 10 Nov 1992 15:47:20 GMT

IMHO, get an outboard battery-powered mic preamp with variable gain.
The reason most cheap tape recorder mic inputs are so poor is that
their fixed gain front end stage is useless.  If your music is real
loud, you distort the preamp, and if the music is too quiet, you 
have to turn the levels way up and get lots of hiss.  It is very
helpful to be able to adjust the front end gain of the preamp so
you can match the dynamic range of the music to the dynamic range
of the recorder.

I can't recommend a unit, unfortunately, which has low noise, since
I built my own transformer-coupled preamp from some parts from an
old Scully reel-to-reel recorder.  However, it is based on a schemo
in "Audio IC Op Amp Applications" published by Howard Sams.

The reason I recommend battery power is that it makes it easier
to get rid of hum and ground loops if you have one less AC cord.

With this setup, I get _excellent_ sound quality with a plain old
cassette deck.  Indeed, I'd bet that the sound is as good as it
is in the kind of rooms I record in.  IMHO, the #1 thing which
determines the sound quality of a recording is the room, and in
particular whether there are ventilation blowers going, fluorescent
lights buzzing, etc.  #2 is the quality of the mics and mic preamp,
#3 is how you place the mics and the musicians, and #9999 is the
quality of the tape recorder!

Flames, comments, etc?

I dont especially want to buy a denon receiver to get the stupid remote...
I know that preprogrammed universal remotes for every single make exist,

I have a question on the impedance matching of audio components.  In most
applications, in order to provide maximum power transfer and minimize
reflections, the output impedance of a component should equal the input
impedance of the device receving the signal.  However, it seems in audio
that you just need to have the output impedance much lower than the input
impedance.  What is the rationale for this ?

Furthermore, what is the impedance of an audio interconnect and how does
this affect the matching problem ?

The generalization is good.  You seem to have an EXCEPTION. Note the absence

   Well an Indigo would be one route to go.  However for the cost, your not 
getting a 'dedicated' audio machine.  It would be much more cost-effective 
just to purchase some kind of digital audio sound editing system.  I'm not 
saying that an Indigo would be a bad choice, but it's designed more for

  Well, actually, just this morning I asked for some opinions about
speakers as low as $400/pair and have already received some pleasant,
informative responses.  This has been the case in the past as well
when I asked for advice on other, lower-priced components.  I have

	before more rumours start and people start accusing hsu
of rippoff prices, let me point out their prices have dropped.
I believe when they started they were $500 each (most people seem to
only want one subwoofer). they are now $750/pair. there seems to
be growing acceptance that most subwoofers are giving significant
output at frequencies high enough that you would want a stereo pair.

Depends on whether you are serious about getting into LD.  I bought a combo
player and sold my CD player even though the CD player sounded substantiall
better than the LD player because I wanted to get into LD and I couldn't
give a stuff about the sound of CDs since I don't buy the things all that
often anyway.

Sound quality is good from the LD player, but it basically sounds like a CD
player for half the price.  On the other hand there is the option to use an
external DAC with it and many people consider LD transports to sound better
than CD only transports, plus LD players should be more durable when
playing CDs because they are designed to use heavier LDs.

Once you get into LD though you are really likely to get hooked, I know I
am.

I have access to a Tascam 424 portable mixer/recorder and a couple

Here's my question:  the 40-voice choir is accompanied by four violins,
one string bass, a tympanist (sp?) and two trumpets.  Can i get away
with using two PZMs for this recording?  Or, should I add some directional
mics for the brass/string portion of the presentation?  The orchestra folks
are placed right next to the choir.

The performance will be held in a church that is fairly large, but there
is very little echo.

Please reply via email if possible.  Thanks in advance!  :-)

I haven't seen a thread about 8 mm VCR. I was told that 8 mm VCR has a better
stereo quality than VHS VCRs. Is this true? Last time I checked around here,
SONY's 8mm VCR was priced around $500. I am not sure about Hi-Fi capability,
but I think it has. To SONY's own Hi-Fi VHS VCRs or well regarded
Mitubishi's VCRs in this group, are  8 mm VCRs' sound and picture quality 
comparable? If this is so, why 8mm VCRs are not beginning to be popular?
There are already many 8mm camcorders around. Besides, it is much better to
store. Why? Just a wondering mind's curiosity.

	Do DAT decks place SCMS codes on recordings made from the
analog inputs? If they do not, then simply connecting the analog outputs
on the CD player to the analog inputs on the DAT deck should
result in a high-quality recording with no limit on the number
of digital generations it can, uh, generate. I realize that this
falls short of the holy grail of a perfect digital copy, but I
would guess that any degradation would be quite small.
	The only problem with this idea is that it would seem
to make the SCMS useless. And it strikes me as absurd that the
record companies would have settled for something so silly. Am
I missing something here? _Do_ DAT decks put the SCMS codes on
anything they record, even from microphones? That seems absurd;
it would mean that DAT decks are incapable of doing anything
useful except to make first generation copies of the recordings
that the whole SCMS system was supposed to protect! What's the
story here?

I was wondering if someone out there could answer a question about filtering
the output of a D/A converter.  Analog filtering, that is.  Why do it?
If you can't hear anything above 20KHz anyway, why bother going through
all the trouble of getting rid of the noise up there?  Maybe that's
cutting it a little close.  But most of the D/A converters made today
have 8X oversampling or more which puts the noise up around 160KHz.
Even if you could hear this, I doubt that your equipment could reproduce
it.  What am I missing here?
