demodulator, one that I would get into the effort and expense

you need a special Technics test record <br>that only
came with that demodulator. <br>If you find one, let
me know because I need <br>one too. <br>Apparently,
these units are not very reliable<br>so it you got a
working unit, you are lucky.<br>I do like the carrier

In my experience, the JVC 4DD-5 is the best
consumer demodulator ever offered to the public. The newer
designs made by all the manufacturers included many
"band-aids" to try to reduce the noise contributed by the
carrier channel. Toward this end, these units all had a
considerably reduced audio bandwidth in the demodulated
difference channels. This does, indeed, reduce the carrier
noise, but it also reduces the separation at high
frequencies and also results in a duller overall sound. The
Technics control that attempts to reduce crosstalk in the
carrier channels was a good thought, but I don't remember
that it ever resulted in any audible improvement.
<br><br>Crosstalk in the carrier channels causes a unique type of
distortion with CD-4 records that JVC called "Type II". This
really is the same type of phenomenon as multipath or
co-channel interference in FM radio reception (remember that
the carriers are frequency modulated). In CD-4
playback, the result is a low-frequency distortion that
sounds rather like farting (pardon my French). This is
easily distinguished from the more common "Type I"
distortion which is the higher frequency ripping sound
associated with temporary loss of the carrier(s). Type II
distortion can be caused by any part of the playback chain
that causes too much crosstalk (lack of separation)
between the two carriers (left and right). Some
demodulators are poorly designed and suffer a lot of this.
Beyond that, cartridges and/or styli are the next most
common culprits. So this brings up a caveat to anyone
who would rebuild or redesign their demodulators: Be
careful with the lead dress of the wires flying around
inside the unit. I know from experience that what seems
like an innocuous placement of wiring inside a
demodulator can result in crosstalk at the supersonic carrier
frequencies which will cause Type II distortion. <br><br>So
far as how you would set the carrier crosstalk
canceller control in the Technics, I would suggest that you
probably need a special test record that has a track with
carrier recorded only on the left side and another track
with carrier only on the right. You would use an
oscilloscope to monitor one or two test points in the
demodulator, and you would adjust for minimum carrier when
there wasn't supposed to be any on the record. This
procedure is necessary because the cancellation circuit is
intended to cancel out crosstalk originating in any part
of the playback chain, including the cartridge as it
plays a record. So just using a signal generator won't
get the job done. I can't actually remember if
Technics provided such a special test record for this
purpose. In lieu of that, if you have a record that
exhibits Type II distortion, you can experiment with this
control to see if you can improve this problem. As I said
earlier, I don't remember noticing that this control
actually did much in the SH-405s that I played
with.<br><br>Greg Bogantz<br>gbogantz@...
So I finally took the plunge and got a Denon
receiver with DPL-II. Following wizardofohm's suggestions,
I set the DPL-II mode to "Music", turned Panorama
off, set the front width to turn off the center
channel and cranked the Dimension so all four speakers
are at the same level.<br><br>I *like* what I hear
when playing back QS, though I don't have any real way
to tell if what I'm hearing is *accurate*. I don't
hear the same constant, obvious separation that I get
from an SQ recording through the Tate, but of course I
also don't get any artifacting. There are occasional
moments of obvious quadraphonicness, though in general it
seems to provide more of a sense of constant
envelopment rather than ping-ponging. Are QS recordings
generally just more conservative in that regard due to the
recording engineers' understanding of the 1970s decoder
deficiencies?<br><br>My real question is: How do I go about getting the
test CD I've heard mentioned here before?
Checking various sites about DVD-A doesn't show
anything new coming for the next months. Is DVD-A going
where original DTS CD are now - aka a dead
market?<br>Well, i liked DVD-A... it is possible from the start to
listen the surround mix with a normal dvd DD player,
until the prices of DVD-A players cool down. Now
gottawait for the Universal Player that handle SACD too.
That's funny, I was just thinking that it looks
like DVD-A titles are starting to take off! Check out
DVDPlanet.com and use their "quick search" for "dvd-audio".
There aren't oodles of new releases, but there are more
coming out now than I've seen in the past, including
titles from Bjork (whoo-hoo!), Barenaked Ladies,
Fabulous Thunderbirds, and some others that don't really
float my boat.<br><br>I am totally enthralled with
DVD-Audio. It's too bad it has a competing format... or
maybe it's too bad that SACD has a competing format...
whichever, it would sure be nicer if there were a single
multi-channel high resolution digital format instead of these
darn competing formats... that's pretty much been the
only constant in the evolution of media; there are
always competing formats! Argh!<br><br>Oh, by the way,
it looks like I'm getting something resembling my
life put back together after a couple months in limbo.
Basically, lots of other priorities pushing aside my
hobbies, but it's good to be back. I've missed you guys!
I don't think it will matter which format wins if
the players will play both. They might can even
coexist, each record label choosing which they wish to
use. The important thing is that surround music wins
acceptance. We have the advantage this time in that home
theater has wedged the doors open, and they can't be
completely closed again. Long live surround sound!<br><br>By
the way, Greg is right about the JVC 4DD5, It is a
very fine demodulator. I have two of them and desire
no other. I once had a chance to play with an SH400,
but I didn't think it sounded as good as my 4DD5.
However, it has a fancy look to it and lots of
adjustments. The 4DD5 just doesn't need them.<br><br>The

>>So I finally took the plunge and got a
Denon receiver with DPL-II<<<br>CONGRATULATIONS
Terry! I predict that you will grow more "impressed"
with PLII as you continue to listen. I'm very glad to
hear the Denon has the full set of
controls.<br><br>>>I don't hear the same constant, obvious separation
that I get from an SQ recording through the
Tate<<<br>Are you listening to QS, SQ or stereo through the
Denon? If it's stereo than a better comparison would be
how does the same stereo music compare when played
through the Tate vs the Denon. <br><br>>>though in
general it seems to provide more of a sense of constant
envelopment rather than ping-ponging. Are QS recordings

SQ. So again I wonder what sort of material you are
playing. If it is QS than you are hearing it as it was
created. If you are playing stereo than just punch
Panorama in & you'll hear the rear speakers open up. Try
some early Thomas Dolby (Golden Age of Wireless), ABC
(How to be a Zillionaire), KLAATU (Madman, Politzania
on the HOPE CD) Becks' Midnite Vulture's, or
anything by the ORB or OMD.<br><br>FWIW, I have had great
success lately with creating my own QS/SQ etc test

>>I was the second bidder for a Technicas

away (as FZ would say: ABSOLUTELY FREE)a Panasonic
SH-400 to a friend. It had the owners manual, service
booklet, & test record. Because he has the only copy of
the setup directions, you might want to write him
with specific ???"s. He is DISCLORDVHD in this club &
can be reached at disclord@.... I don't think
he'd mind.<br><br>As stated before it is a problematic
unit. The previous owner would occasionally have to
wiggle the daughter boards in it to get to go again.
Also, the rated output is only 200mV, approx 1/10 of a
CD's max level. So it's not a great match for many
newer input sensitivities.<br><br>Scott<br><br>Scott

Jackson Browne - " Running On Empty " DVD-A is
scheduled for October release according to Browne's
engineer Greg Ladanyi .<br><br> For songs actually
recorded in hotel rooms , Ladanyi has mixed them so the
listener is placed in the middle of the band . For songs
recorded at concerts , Ladanyi has mixed them so that the
listener is placed part way back in the audience .<br><br>

> Are you listening to QS, SQ or stereo
through the Denon?<br><br>QS, though I don't have that
many albums. The ones I've really listened to are
<br>Joe Walsh's "The Smoker You Drink..." (vinyl), the
Grateful Dead's "Steal Your <br>Face" (CD), Syngery's
"Electronic Realizations..." (the CD actually has an
<br>official QS logo in the booklet!) and Dan Hicks' "Strike
it Rich" (CD). One of <br>the few really obvious
moments happens in Joe Walsh's "Rocky Mountain Way" when
<br>things move pretty obviously to the back for the mouth
tube solo. I'm not 100% <br>sure the Dead album is QS,
despite the claim at
<br><a href=http://personal.riverusers.com/~manderso/quaddisc/quadcds.htm.
target=new>http://personal.riverusers.com/~manderso/quaddisc/quadcds.htm.</a>
<br>There's a credit on the CD for "Stereo
Synthesis", though as far as I <br>can tell it's a genuine
stereo recording.<br><br>I've also played around with
some Ovation stuff, including the EV-4 <br>version of
"Rich Mountain Tower" and their unspecified format quad
<br>sampler album. Oh, and the priceless "QS 4-Channel Hit
Deluxe" <br>Toshiba demo record.<br><br>> FWIW, I have
had great success lately with creating my own QS/SQ
etc<br>> test signals via Cool Edit 2000.<br><br>That
sounds interesting!

Good to know. The JB dvd-a wasn't noted on the
web page i saw. I like that album and since it is on
WEA anywhere i presume it will be available in Europe
too (got hell of times to get Deep Purple and EL&P
from the USA - they can't be imported because they are
not on the right label here).<br>There is a online
version of the MIX you quote?

Hey, thanks for that pointer to the 5.1 article
at mixonline.com! I just about wet my pants when I
read that Mickey Hart was remixing the Grateful Dead
albums "American Beauty" and "Workingman's Dead" for
DVD-Audio! Very cool!<br><br>After a bit more research, I
found another link talking about the same
thing:<br><br><a href=http://www.sonicnet.com/news/story.jhtml?id=1444425
target=new>http://www.sonicnet.com/news/story.jhtml?id=1444425</a><br><br>Sounds
like there is more on the way, too! Even if you
don't fancy yourself a deadhead (I don't, I just love
their music) you owe it to yourself to check out
"American Beauty". I can't wait to hear it in high
resolution 5.1!
Just wanted to say that I posted the info on the
Dead titles back on June 25. Go back and check message
#1495. BTW, if you like GD's music, you might be
interested in a new set due out Oct 16 titled "Grateful
Dead-Golden Road" a 12 cd set. Should be enough music on
there to last a while. Be sure and read my next post
for specific dates on the DVD-A titles.
For those that are interested, the following is a
list of DVD-A titles with announced release
dates.<br><br>Sep 25 - America:Homecoming<br>Oct 30 - Grateful
Dead:American Beauty<br>Oct 30 - Foreigner:Foreigner 4<br>Nov
27 - Carly Simon:No Secrets<br>Nov 27 - Grateful
Dead:Working Man's Dead<br>Dec 18 - Doobie Brothers: The
Captain And Me<br>Dec 18 - Randy Newman:Little
Criminals<br>Dec 18 - Van Morrison:Moondance<br><br>In my last
update, I made note that Meat Loaf: Bat Out Of Hell, was
also due out this summer. It has been pushed back to
sometime later this year. As it's also been announced for
release on multichannel SACD, my guess is Sony pushed the
DVD-A version back in order to get the SACD out first.
Hardware News: The Apex AD-7701 (plays both DVD-A and
SACD) was due out the end of Aug. Apex has now added a
webpage to their site and are getting ready to ship. One
of the major web retailers is also now accepting
pre-orders for it at $299.00. I'm waiting for a email from
them with particulars on release date. As soon as I
hear back, I'll post the info to the group. In the
meantime, here's the link to the
webpage.<br><br><a href=http://www.apexdigitalinc.com/ad-7701.htm

Gee, sorry, didn't mean to step on anyone's toes
or try to steal your thunder! I haven't been
following this discussion group for the last coupla
months.<br><br>Anyhow, you are hereby given credit for pointing that
