assistant: "Levels" as in recording levels?   What is the proper recording level
for Dolby B/C ?
My tape deck has an auto tape selector.  I suppose it changes automatically
to the correct EQ when I insert a metal or chrome tape.   But now I'm not
sure whether or not its working because turning on Dolby B on a metal tape
causes the sound to be flatter than normal.   (this doesn't occur
to such extreme on a Normal Bias tape).
So, say that the EQ level is that of a normal bias tape when I made
the NR recording.  Will the playback sound flatter?  Or are metal tapes
not designed for NR recording since from your explanation, metal tapes
seem to do the same thing.   How do I test the tape deck whether or not
it has a broken tape selector?  (I was fine with a tape selector switch,
but nooo, they got to make it AUTO with no lights).
Now what is "Bias" anyway? :)
So basically, a tape recorded with Dolby NR must be played back with
NR ON, otherwise the sound will not be the same since Dolby alters it
during the recording process.
What if a tape is recorded with Dolby C or HX PRO but the playback is
on a machine that doesn't support C/HX.  Will the sound be compromised
if a C/HX recording is played back on type B machine?
But since the sound on the CD is digital, rotational accuracy will not
alter the sound, correct?   If the rotational problem is not minor, then
I presume the music will just skip, rather than degrade.
But is there more data at the outer rim of the disc than at the inner rim?
Shock/skip protection?
It was very helpful, thank you.

       Hi Lewis,   Have seen a few high end "headphone amps" in some of the
catalogs and the specs looked fascinating. Needless to say the cost was
prohibitive for all but a few. One was solid state and three more models were
tubed and made to sit at the listeners side. I had to laugh, one even had a
remote! Although I have to admire the designers outlook/attitude of including
the remote.
       Is the major selling point the exceptional clean sound? Tweaked
especially for particular headphones? Or possibly the "warmth" from the tube
models? For apartment dwellers. etc, they could be the hot ticket to high end
sound if they perform anything like their promotional material. If memory
serves they were produced by the same company that makes some of the better
headphones, but I would have to check.
Cheers, John

assistant: Take one of your own disks to any store that sells either portables or
units that have a window so you can see the disk while playing.  Play
the first track, then go to the last.  You'll see what I mean. :-)
The datastream from the CD must be constant.  The CD employs what's
known as CLV, constant linear velocity.  If you remember back to your
vinyl days, :-) the inner groves of a record always had more distortion.
This was due to both the Geometry of the tone arm but also due to the
fact that more vinyl passed by the sylus at the outer edge than in the
centre.  The CD compansates for that by spinning the disk faster at the
inner diameters, and since the CD is read from centre to edge, it spins
the fastest at the start.

assistant: Agreed.  They were better than my loudspeakers throughout my
college days...
Picked up a Grado SR60 for the discman at work. After upgrading

My only complain is the AKGs are hot during extended listening, but
I guess studio/DJ work would like their isolation when compared
to more open air and lighter designs.

assistant: Hi John Holinsworth,
The 4 ohm speakers have a smaller impedence then the 8 ohm ones, that means
the current (I) will be higher with the 4 ohm speakers then with the 8 ohm
ones.
 The result will be louder sound with the 4 ohm speakers when the volume
control is on X position.
As for damage . . . .
 I cant tell U the there wont be, but It Can (Not for sure) butn out both
 The reciever and the speakers, coz when the current is higher the heat of
 the electric components will rise, if they will not be able to dispose of
 all of it they will burn out.

assistant: Kinda like the location at the last concert I was privy to backstage access.
There was no separate monitor mix so everything ran from the foh board,
BESIDE the stage.  I went out into the crowd about mid way from the stage to
the side of the nearest building (which would bounce back the sound) (outside
concert at White's Country Store in Seguin for Darrell McCall's concert two
weekends ago).  The sound man was attempting to run sound from the side,
without having to go in front of the crowd to get levels set... and he kept
saying, "I can't tell what I'm doing!" - Geesh... I headed to a spot near
where the first "envelope" should close and listened.  I went back and gave
him my recommendations.  Being 1) a woman first 2)someone who he didn't know
anything about, he said, "No way..."  The mix was typical smiley face and the
vocals were so weak that Darrell could barely be heard except when he pushed
vocals heavily.  I told the *soundman*, "Go listen out front...where you
should be anyway!"  Off he went in a huff, but came back in with his "tail
between his legs", saying, "You're right"  and redid the mix.  Later, as the
evening progressed and stage volume increased (as per normal in a drinking
atmosphere!), the mids started ringing due to the increase of amps on
stage... He couldn't find the problem, although there were 4 channels with
mids nearly wide open. (no solo on the board -sigh).  I showed him which ones
to check, even told him it would be the fiddle... "No way!" was again his
answer.  Then, about 2 songs later, the "lightbulb" finally went off
overhead, and he went through each mid setting and found the ring - AHA,  the
fiddle! <beg>

Write your reply.

assistant: So the CD player rotates the CD at different speeds as it reads
the disc from inside to outside?  You'd think that it would be difficult
to set each CD player to such exact specs, but it does make sense that
the speed would have to change, otherwise your data would be coming off
the disc at variable rates.  John has a good point here.  I thought that
the CD player spun the disc at a constant rate, like a record player.
Though now you have me confused.  A record player rotates at a constant
rate, yet even though the inside edges and the outside edges travel at
different speeds, their is no difference in pitch between the outside
and inside edges.  (Meaning if you had a 33 record playing at 45rpm,
it'd be higher pitched, yet even though the edges are traveling at
different speeds, it's the same pitch throughout the record).  Seeing
how it's summer, my brain isn't working the way it should, so can you
please explain this?

assistant: And so it came to pass, on 03-08-96 16:28,
   that Phil Roberts spake unto All :
They typically feed a small RF-modulator box that installs in the antenna
lead.  Most modulators can be set to one of two frequencies, usually two
"stations" apart and low on the band (89.5 and 89.9MHz, for example).
Not really, since not only does the modulator install inline with the antenna
lead, but there are typically at least three wire connections to the car
(ground, and constant and switched power).
I did see a "demo" version of a Pioneer unit once, that was stuffed in a nice
padded case, had a big alligator clip on the end of the antenna lead, and a
cigarette-lighter plug on the power leads.  It was great for salesdroids in
the shop I worked in (as an installer) at the time.  I wouldn't generally
recommend this as a "transportable" concept though.
Obviously, these are not intended to be high-end CD systems, but a simple,
low-cost add-on for factory stereo systems to provide the ability to play
CDs, and little more.  For what they are, they're great.
