The kind of "compression" in DCC is NOT the kind you are familiar with
in computers.   There is no "uncompression".  Bandwidth is saved by

data being thrown away, and once that is done, that data is not

Well Jamie - the CD manufacturers saw the DAT as a threat at one time.

They busted their buns pushing the CD in the formative years.  They
felt they had to get 5% of the recorded market by the time the car DATs
hit the street or they would lose out to DAT.

It's interesting to see how things worked out - and how CD took off
faster than any other consumer audio format in history.

As to DATs in cars all of the people I know who have DATs in their cars
(see footnote) have had intermittent drop-out problems.  

A tape will play along, then drop out for a moment.  If it is played
again there is no problem.   In my car - Honda CRX SI - it is mounted
where the cassette hold once was.  Not a real heat problem.

My best friend has one in his 944 Turbo Porsche (with performance
chips) and he feels that in his installation it is a heat build up
problem.   That I can see in his, but not mine.  He got is race
instructors license in that car at Sebring last week, and I'd venture a
guess that it is the only racing machine with a DAT in it.

** footnote - when I said ALL the people that I know who have DATs - it
is a small group.  Two - Andy and I.  Couldn't resist at the $299 price
when they were closed out - Sony DTX-10 (??)  :-)

I am just wondering if someone could give me some insight into the great
intertest in the new Sony MD. I for one do not see how this medium can
ever take hold in the marketplace. The CD is already well established
and will not disappear overnight due to the billions that have been
invested in it. To me, Sony seems to bring out new technologies without
first doing a proper market analysis. Who is actually willing to
purchase this system after a large investment in CD's has been made, and
that will deliver inferior sonics to the "lowly" CD? Just an interested
audiophile.

Summary: Digital _Power_ Amps
Date: 23 Nov 92 19:10:10 GMT
Organization: cam.eng


Didn't Wadia introduce about half a year ago a true digital _power_ amp that
used multibit switching to achieve power levels (c.15V and 2A)? I was intrigued
by this amp because unlike all the others it was truly digital with even the
volume contol implemented digitally.

On a less esoteric scale, Meridian (from Boothroyd Stuart) have always been
proponents of digital. To this end, they have produced the D600 and D6000
digital loudspeakers. The D600 has an internal Philips bitstream converter
whiuch feed a conventional poweramp and Xovers to the drive units.

The D6000 is another kettle of fish, it implements its Xover digitally with
each unit having its own dedicated power amp optimised for its particular
bandwidth and power requirements. To top it off, all the tone control and
volume is implemented by DSP techniques.

Meridian also have a digital preamp the 601 (if memory serves) which has
extensive DSP capabilities (including RIAA EQ,Dolby ProLogic, KEF KUBE EQ
settings, and others). It accepts no analogue inputs. To connect a record
player, you have to purchase their corresponding ADC (608?) to give it a
digital datatream.

All these products have made good impressions under subjective review and have
even prompted favourable comments from die-hard analogue reviewers listening 
to record players using the digital preamp and/or the digital loudspeakers.

Philips have also introduced their versio of the digital loudspeaker, but
details of this escape me at this moment.

Actually you're both wrong.  The reason why we need filtering is because 
real functions are sampled  over finite intervals, i.e., we can't really
produce a delta function.  This causes distortion, however, it is all outside
of the frequency range of the original function (remember we filtered the 
original function to prevent aliasing).  Try sampling and recovering a 
signal, then display it on a scope or spectrum analyzer, it is pretty obvious.
(Dennis, you should have done this or will do this in EE440 lab).

the extra subwoofers.  I've heard good things about the Ensemble and
the Ambience speakers, but I have yet to hear anyone comment on the
complete surround system.  

The factory direct prices are great and the return policy is excellent,
but I sure wish I could hear them before buying.  Has anyone bit the

Hi.

Would some of you Audio Wizards with knowledge regarding this please help  me
out here.  I remember reading an article (Popualar Science, I *think*) quite 
a while back regarding CD's and the degeneration of them when not played for 
long periods of time.  If I remember correctly, it has something to do with 
the type of plastic used in CD's. Also apparently this effect can be negated 
by playing your CD's occasionaly. The type of laser used apparently also 
makes a difference. (Something to do with the light frequency.)

I've got a friend who's quite an audio fanatic and he wants to know if this
is true/false etc.  Any and all info regarding this will be most appreciated.

Thanks in advance.

Walter.

All this talk about DCC, DAT, and MD has caused me some concern.
I'm not concerned about the losses that will probably take place
between generations of DCCs and MDs, but what concerns me is
the apparent endorsement of an obviously inferior medium:  tape.

All tapes wear out, all tapes can get eaten by a deck, and all
tapes have a high rate of defectiveness.  DAT and DCC may sound
better, but they don't fix what I think is the biggest problem
with analog cassettes:  durability.  (not to mention random-access)

By the way, I work in a music store, so I get to see just how many
defective tapes we get back.  It's quite a few.  Incidentally,
we do get a few CD's back, but it's usually because the numbskulls
don't know about cleaning them.  The only truly defective disks
we get are from labeling ink getting on the playing side of a disk
from poor pressing (like overspray, but not as severe).  
I've only seen two disks come back with this problem, in over a 
year.  All other disks, I just clean them, verify that they play
on our CD player, then send the customer on his/her way, feeling 
stupid.
