Hello,
    
	I have an older pioneer a/v receiver. And up until about 2 weeks ago
it was functioning normally.  Now for some reason or another, I need to turn
the volume to almost max before I can begin to hear anything from the 
speakers.  Haven't changed anything in the setup except rooms (I gave it to
my brother when I bought my technics)  Can anyone think of a reason why
this would happen and an inexpensive way to fix it.

Thanks
  Geno

Most followups on this topic assume an X percentage pitch change either
upward or downward is the same musical interval.  I would agree that
for our purposes this is close enough, since the 10% change is only an
approximation to begin with.  However, before the topic is completely
dead, bear with my pedantry.

If we suppose an exact 50% change in pitch, is the musical interval
the same upwards or downwards?  If we start with 440 Hz = A, then a
50% increase brings us to 660 Hz = E, one fifth upward, while a 50%
decrease brings us to 220 Hz = A, one octave down.

Clearly, this asymmetry is relevant to few rec.audio readers.
However, in some instances, the difference is more than theoretical.

A local dealer has what seems to be a fairly decent price for a 
multi-format laser disk player.... a Sony MDP333.

It comes with S-Video out, Optical Digital out, and plays
anything from the LaserDisks down to the CD-3's.


Does anyone have any opinions, good or bad, about this product?
(Is this a REALLY OLD thing?) 

They've got it for $500.00 Canadian, (About $400.00 USD) 
Good price? Reasonable price, a steal?

I'd appreciate mailed responses, although I will monitor
for posted follow-ups... 

I'll post a summary of whatever I hear...

Thanks

  Some people claim that drawing lines on the non-label side of

Actually, the data and the label are both on the same side of the CD. The  
data is read through the plastic, from the opposite (non-label) side.

   How to adjust it will depend on whether or not your specific deck
   has SEPARATE record and playback heads....

   If you have an FM tuner which you can make produce hiss when
   tuned BETWEEN stations (you may have to defeat "mute"), this
   makes an excellent source of a bias-adjustment signal.  

   Record the hiss at moderate levels.  I'd recommend -10 to 20 dB,
   as unless your deck has HX Pro, you might run into other problems
   near 0 dB.   

     o  If you have separate playback and record heads (so you
	can do off-tape monitoring), listen to the monitor output
	and the input (switch between same).  Adjust the bias
	control until the two sound alike in the upper treble.  

	Some folks do this on every individual tape, some on each
	batch of tape, for critical recordings.

     o  If you don't have real-time monitoring, you'll have to 
	record sections of the interstation noise and then play them
	back.   It's not really a problem, as you'll rapidly
	discover that turning the bias one way boosts treble, the
	other way cuts it.  

In either mode, the goal is to make the recorded interstation noise
sound as much like the original as possible.   Bias affects mostly
the quality of the upper treble...and the effects are usually pretty
obvious.

  I have a pair of KLH 3 way 12'' speakers that I got at an audio
show a year ago. They work fine. But the bass is exteremely muddy. My
roommates fisher 10'' 3-way sound better which is sad. When dissecting
my speakers I noticed that there are no crossovers for the midrange
and woofer!! Only a small filter capacitor on the tweeter. That as 
well as having a cheap paper cone woofer thats made out of grocery bags
 Would it be worth it just upgrading the speakers with new pioneer
poly cone woffers and installing a 3-way crossover. For about $100
or do I really need a pair of Cerwin Vegas or infiniti's to get a big
difference?

   Programmability is nice. Complete controll over the subcode information

half-speed (long play) can be handy. A full-function remote.

   There are a couple of full-feature home decks in that range and some

There was an article in AUDIO magazine about this a while back.
They talked to several engineers who had actually worked on the
design of commercial CD players.  Their consensus was that there was
no difference between a well-designed one-beam system and a well-designed
three-beam system, but the public thought three beams were better so
they were under corporate pressure to design three-beam systems.

I think this should read "Are there any great sounding speakers in this price
range? ( <$500)", and the answer is of course no! (unless if you mean $500 each).
If you really want to upgrade your system piecewise, spend more on your speakers.
Your speakers should be about %50 of your total system cost, are you planning
on only spending $1000 on your final system?  There are a lot of nice speakers
in the $500-$1000 category, and some really great ones for >$1000.  If you can't
afford better speakers, I would advise you to wait.  You won't be a poor student
forever and it would be silly to throw away $500 on something you will want to
replace in a few years.

Most companies rate their speakers at either 4 or 8 ohms. An 8 ohm speaker
usually reads about 6 ohms DCR, and will have a minimum impedance of
about 6.5 ohms or so....  Its a messed up system, but not nearly as messed
up as the way some companies do their power ratings (ahem.....ADVENT).

Steve,

purchasing components from them but fear that the installation may
prove too difficult.  If you ask, they will send you a two page copy
from the scosche installation manual that details radio, speaker and
antenna instalation in the vehicle.
