Yeah, the amplifier really sucks. I worked for Lafayette back then, and
the amplifier sounded bad even then. Of course, it may well be broken on
top of that.

   Only your ears can tell.  If the Star Trek, Batman II, Top Gun
   laserdisks don't annoy the heck out of the neighbors, try adding
   a subwoofer or two.   Seriously, you should be able to FEEL most
   of those in your chest even at moderate volume levels with a good
   bass system.  [Telarc's "Time Warp", Stanford's "Digital Domain",
   and Dorian's Saint Saens "Organ Symphony" are also good
   sources...extra credit for "Break Like the Wind". ]

   Make sure your powered sub has a low-pass, the output of the Sony
   is full-range if I recall correctly...and can be used as a second
   "Center" output if desired.

Hello,

I would like to get some suggestions from the net on what CD's are good
for listening to while evaluating Hi-Fi systems.  I feel that Female vocals,
piano, acoustic guitars and anything non-electric makes the best music
for these purposes.

I just bough a CD called the "Famous Blue Raincoat" by Jennifer Warner.
(The spelling my be wrong on the last name, I'll check.)  It sounds great
and I plan to listen to it several times and then take it with me while
checking out other speakers/amps/CD players/etc.

I am not exposed to much music like this so some suggestions would be great.
Please respond by e-mail.

Thanks in advance and I'll post the results.

    No, but there is a pretty brisk market in those big Cadillac

    But with the alternator running, the system should be at closer
    to 13.7 volts.

Organization: Dept. of Comp. Sci., Victoria Uni. of Wellington, New Zealand.
Date: Wed, 27 Jan 1993 08:02:09 GMT


Some years ago in Canada, I bought a QUAD 33 pre-amp and a QUAD 303
power-amp. They have given faithful service.
I recently brought them here to New Zealand.

I had thought they were both dual-voltage.
Sort of.

The 303 power amp indeed has an interesting rotary pin plug that
lets you choose between 110, 120, 220, and 240.

But the 33 pre amp has no external switch; instead it has a piece
of paper upon which is typed "120 VAC".

Inside, however, the power connector seems to go through a unit
with 3 taps, labelled "0" "127" and "250". The leads are connected
to "0" and "127".

So what I want to know is this: 
can I merely move the wire from "127" to "250" to make this unit
usable to me here in New Zealand?

I guess I'm hoping the unit really is fully dual-voltage, but they
were too stingy to include a proper voltage switch.

Enlightenment, anyone?

Subject: Strange problem with Sony Receiver/JBL speakers
Organization: University of Illinois at Urbana
Date: Thu, 21 Jan 1993 01:58:57 GMT

My roommate and one of his friends both claim to have experienced a strange
problem with their Sony receivers.  They both have JBL 3800 speakers (8"
woofer, 5" mid, & 1" tweeter) and a Sony 80 watt per channel receiver.
One is a STR-AV770 and the other is the newer 790 with Pro-Logic.
They both have noticed a severe lack of Bass with the Sony amps.  Both
also have occasionally heard a loud popping sound from the woofers when
playing music loudly, as if the wofer cone were being driven past its limits.
I have heard the sounds, and it definitely seems that the speakers were not
putting out Bass up to their capabilities.  My roommate was convinced when
he substituted a much older receiver that was his father's.  The amp is
not a name brand yet is able to produce significantly higher Bass levels.
His friend spoke with the store he bought the speakers and receiver at and
they told him that the crossover in the JBLs is incompatible with most types
of Sony 80 watt per channel receivers and that he should get a different
brand of receiver.  I have never heard of any such thing in my life.  Is it
possible that Sony receivers are just junk?  My STR-GX7es is capable of
making my cervin-vega subwoofer knock shelves off of walls.  I seriously 
doubt that a receiver could be "incompatible" with a speaker.  I thought
I understood audio quite well, but I am at a loss.  The difference is
noticeable with the JBL speakers when switching amps, but not with others,
such as my Polks.     Weird...

Anyone?

Rumor has it that the RCA tapes are "junk"  The only way to find out
though is to compare them directly to a known good product from MRL or
STL.

Good luck Tony,  if they check out I may be in the market for a couple
of them!

Oh and the way that I have found best to set head height is to smear a
bit of grease pencil on the head in question, run some scratch tape
across the head then look at the residual grease.  You can visually
see if the tape is centered on the head as well as checking the tapes
footprint on the head.  That gives a lot of info: back tension, wear,
etc.   Don't forget to clean the heads after you are done!

I recently bought the Aphex C2.  This was my first aural exciter purchase.
I immediately dug up my DAT mixes and ran them through the C2 to see how
they might have been improved by it.  There is no question about the
high end.  The *prudent* use of the high end exciter absolutely improved
clarity, sparkle, and stereo separation.  In fact, just when I thought
I wasn't really hearing much effect I would engage the bypass to compare
the original and be surprised by the flat, lifeless sound of the original.
It didn't add any noticable noise to the mix and is quality enough for
digital recording.  (However, if you feed it a really noisy source, it
will only make it worse.)

As for Big Bottom, I have mixed feelings.  I can't say that it made me
feel like I died and went to bass heaven (yes I was hoping for that).
It did improve the bass response without overdoing the signal output.
The amount of bass enhancement appears to be dynamically adjusted
(based on the source material) so that the signal boost is kept
under control.  All in all, it sounded like the bass EQ was turned
up without the corresponding output level changing significantly
(i.e. A *safe* bass boost).  I was listening primarily to the kick
drum and bass guitar.  However, one magazine review marveled at
what Big Bottom did to toms.  I didn't pay much attention to the toms
so there could be more potential than I'm describing.

(BTW: The "Keyboard" review mentioned that some of the early production
units of the C2 generated excessive noise when operating in the +4dB 
setting.  There has been a field upgrade to fix that problem should
you end up with one of those early units.)

Bradley broadcast, amog others (i think Harris-allied, as well) sell
rackmount shelves, which you can just screw the units down to. Not terribly
elegant, or all that cheap, but better than angle-iron, IMHO.

Harris is in Richmond, IN. I don't remember where Bradley is, though I seem
to recall that it's somewhere in CA. E-mail me, if you can't find this info
elsewhere.

the shelves cost ~$40.

I assume the Tape Eliminator does not add hiss or wow and flutter.  This
would allow the engineer to choose the so-called "analog warmth" without
the down side of analog tape.

The only company I have seen that offers a console with Gates on every channel
is ATI. They market a board called the Paragon, it is a very highend live console. If I remember correctly it also offers a Compressor on each channel! 
To bad there isn't a lower-end $10,000 console that offers dynamic processing.

Discussion about downward expanders (noise removal) continued:

Let me put in a plug for the BOSS NS-50.  I always keep this baby plugged 
into my mixer's stereo output with a long decay threshhold.


Advantages:	Instant Open.  You hear all of a rising edge on a waveform.

		Set it and forget it!  Nno playing with settings all of the
		time, it just quietly does what it has been designed to do.


Disadvantages:	It's only a downward expander.  It will lower the noise floor
		but if your sample is noisy you can't do anything about it.
		It does not have the ability to dynamicly roll off various
		frequencies when you need to de-noise a noisy source signal.  


Can anyone out there descibe how the HUSH-II circutry works?  Can this affect
a noisy sample?

Sorry, but without an external digital mixer (Yamaha DMP-7D for example),  
digital I/O does not allow for level changes.  Also, there are small clicks  
produced on the Panasonic and Sony DAT recorders I've used when pause engaged.
I've had to resort to Dyaxis or Sound Tools to properly do what you want to do,  
or go analog...

The ATM Paragon, around $80-90k (you also get compression/channel) and the
JBL/Soundcraft Europa, around $50-60K, are two that I know of. I am not aware
of any inexpensive, small-format mixers with gating per channel... with the
possible exception of the Yamaha digital mixers ($?) which are too small, too
expensive and too difficult to use for live.

With the price of 4-8 channel outboard gate units at $300-500, I would think
inserting as many as needed would be an attractive alternative. Both the above
consoles are not only expensive, but also extremely large and heavy. The price
of a road case for one is equivalent to the console budgets for many. :-)
