RE: MD: Sony PC-to-MD interface?

2000-08-14 Thread WZ


Hi,

I'm wondering if anyone has used the Xitel DG1 USB-MD adapter ?  For those
that have it, do you need to use the supplied software, or can you use any
software (winamp, windows media player, ...etc) to play out of the xitel
device.  I assume it simply shows up as another audio device ?  Do the track
marks work automatically even using audio file players besides the supplied
one ?

I'm interested in the device, however, besides mp3 decoding, I'd need it to
work also with playing of WAV files and other audio format files.  This
seems like a cheap alternative for off-board D/A conversions instead of
getting an audio card with digital out.

regards,
Wayne

sounds like it's not re-reading TOCs of new discs ?  When you remove the
battery, it resets the TOC in memory.

Perhaps the small button that senses whether a disc has been
removed/inserted has gone bad ?

Just a guess...

 Subject: MD: R50 Problem



 Well, after a good few years with my buddy, the Sony R-50, it has
 a problem. A strange one at that.

 It will only play ONE disc and that disc being the last played!
 After a I play a disc, I have to remove the battery and let the
 unit "reset" itself. Once the battery has been out for a few
 hours I can play any disc, but once I choose to play any disc at
 length the unit will not play another until the battery is
 removed again! The unit tries to read the disc but either nothing
 happens or I get a "disc error" message.

 Any suggestions?

 Thanks in advance.

RE: MD: MDX7900 tel. mute pin

2000-06-01 Thread WZ


 You need a full handsfree car kit (preferably original, as many
 aftermarket
 kits don't have the lead) that suits your phone. Then you just connect the
 car kit's radio mute lead to the deck's tel mute lead, and there you go.
 Next call that comes in, or that you make, the handsfree kit will ground
 that connection, thereby enabling the Tel Mute function of your deck.

Ah, so when a call comes in, the tel mute lead is grounded ?  Maybe I can
rig something up myself.  I already have a handsfree kit so buying a full
handsfree car kit is not an option for me.

No, most of the other major manufacturers also make MD changers, but they
are really expensive and really rare.  So effectively, yes, Sony is the only
company that makes MD changers... which limits my head unit choices to Sony,
which is unfortunate.

Does anyone know if:

1) Sony changers (MD/CD) uni-link can be adapter-converted to work with
other manufacturer HU for cheap ?

2) Anyone makes a CD changer that buffers the signal so disc changes take
very little time as opposed to the 4-5second disc swaps common in CD
changers nowadays ?

RE: MD: MZ-R30 vs. MZ-R37 vs. MD MS-702 vs. MZ-R90, et. al.

2000-05-09 Thread WZ


 Remotes: I don't use them.  Too many wires to get tangled in whatever.
 That said, the R30 has the simplest, most straight-forward remote of the
 bunch.

Does the R30 have the same remote as the R50 ?  I find that i really like
the R50 remote.  I am using this in my car, and I can grab the remove, and
stop/play tracks,seek,track seek and change volumes without looking at it.
Of course to each their own.

 Titling: Prize goes to the 722.  A friend of mine described it as cracking
 a safe.  The big jog dial really rocks.  Second worst goes to the R37 just

hmmm, did your friend really mean it was easy ?  I have a really difficult
time cracking safes. :)

 the front panel buttons can be used, much like the Sharp 702.  Last place
 goes to the R30/R50: that thumbscrew they call a jog wheel is the worst
 pain in the thumb ever.

Hmm, I really like the job wheel on the R50.  My thumb has no problems with
it, and I can title with one thumb.  I rotate the wheel, then push down.
I've never used the 722 but I would imagine the big wheel would be handy,
but I have used buttons to title like the 702 and they are a big pain in the
you-know-where.  Again, to each his own.


 R30: A good recorder for digital input, but setting record levels for line
 or mic input is a pain, and they do not keep between discs so you have to
 reset them.

I believe ( i haven't checked for sure) that the R50's manual recording
level doesn't change between discs.

 Sony vs. Sharp: End Search ('nuff said).  When shifting character sets
 (upper, lower, special), the R90 resets the letter to "A" each cycle; 702
 is smart enough to remember that "n" and "N" are the same letter.

R50 is similar to the 702.  Then again I have the JDM version so the int.
version may be different.

RE: MD: md compression

 First off dont get all bent out of shape on the compression arguement.  =
 what i was curious about is from what i've read ATRAC removes sounds =
 that are not hearable by the human ear.  my question is what frequency =
 does the MD stop recording at?  I ask this because recently i was =
 playing around with a tone generator (stomper) and made a 15 hz sound.  =
 outputted it to my md deck, recorded it then played it through my home =
 stero.  Strangly enough my sub was playing it (i couldn't actually hear =
 it, but i could definately see and feel it)  It is a sunfire signature =
 sub.  So what is actually cut out when recorded to a md?

Well your sub should be playing a 15hz signal.  Any other speaker you have
doesn't have the freq range to play a 15hz audibly.

I'm not sure what the lower limit is, but the upper limit I think is either
20kHz or 22kHz.  I believe minidisc.org has the specs somewhere.

RE: MD: digital recording between sony discman d-ej715 and sony md mz-r70

2000-05-07 Thread WZ


Just to double check that this "static" doesn't exist on the original CD ?
I know some of my CDs have the static, hiss, pop associated with vinyl.

Also, what does the level meter on the r70 say at the point of  the static,
is it maxed out ?  If not, then it's not the recording level.

Something to try, record via analog cable and see if you still hear the
static.

 of the 'Third Eye Blind - Blue' cd there are many points where static is
 clearly noticable. i use a sony optical cable (poc-15b), sony
 blanks, and i
 o i need to manually lower the recording level? or could this be
 limitations of the ATRAC the mz-r70 uses? would it help to use higher
 quality media like the ceramic sony discs? please help!

MD discs are discs.  Like computer discs, the quality does not depend on the
disc.  Even couple years ago, it was determined that most MDs had a block
error rate well below (was it 160 or 220?), which is 100% correctable with
ATRAC's error correction algorithm.

 I find that my Sharp-831 does not offer particularly good
 compression. I can
 clearly HEAR the artifacts, especially if the music contains a
 quiet passage
 that contains a proportionately large amount of background hiss, and on
 cymbals, hihats, etc.
 Is this a feature of the Sharp ATRAC scheme or is it a limitation of
 portables in general? I ask this because I've borrowed some MDs
 of the SAME
 music recorded on a Sony deck (not portable) and the difference is quite
 astonishing.

Just remember, it could also be due to the ADCs.  Decks often have much
better ADCs than portables.

A friend of mine is experiencing the dreaded UTOC error on his 702.  It

the R50s.  Or will opening the door notify the unit that a disc has been
inserted ?

I've found the button that determines whether a disc is in the unit, but
what I've found out that once you "open" the door of the clamshell, the unit
knows, so the next time you close the door, it re-reads the TOC.  I'm going
to open up the top tomorrow and see if I can fool the button/lever that
deterines whether the door is closed or not.

Anyone have any info, I'd appreciate it.  Like how many springs I should

RE: MD: compression

2000-05-01 Thread WZ


 You always get 120 minues in SP mode, whether you are recording your
 favorite program, static, or nothing at all.  The data itself has a
 constant, quantifiable size.  You can run the tape slower, to fit more
 data, but quality drops in proportion to speed.  Sounds exactly like lossy
 compression to me: less quality, more data in a given quantity of media.

Depending on the quality of the magnetic media on the tape, running in EP
mode will not suffer in quality.

How is it lossy compression ?  What is being compressed ?  Can you explain
why the quality suffers ?  I don't think the VCR is performing lossy
compression.  The quality drop is due to the magnetic media.  And no, the
media is not perform analog compression.  It if was claimed it is, then it's
saying that an el cheapo 60min no-name audio tape after playback 10 times
was compressing since the quality now sucks.

 My point was never about whether or not it is generally considered to be
 compression, because it obviously isn't.  The point is whether or not it
 actually *is* compression.

?! Does this even make sense ?  A to D, is not compression period.

 Is reducing the "size" of analog data somehow not compression?  Would your
 professor care to explain why reducing the size of analog data is not
 compression?

How do you reduce the size of analog data ?  What is the size of analog data
?  Like I said before, size of analog data is not defined.

Regarding your point about density defining analog data size.  You
conveniently deleted my point about 74 vs 80min MDs.  density is different,
yet no compression took place.

in dubbing a CD to MD and titling it...etc (yes I know about the MXD3).
Also MD isn't as popular here compared to Japan, so all my friends have CDs,
and a CD player would be nice for those road trips when I want to listen to
my friends CD.  Lastly, cost.  An MD head unit is usually more expensive
than a comparable CD HU.

While I like those CD/MD single DIN units, they cost the same as a MD with
CD changer or CD with MD changer!  Now that's crazy!

MD: Car MD/CD combo ?

2000-04-26 Thread WZ


Hi,
I've had my new car with the stock tape deck for more than 6 months and I
can't stand using my R50 with the tape adapter. Not only is it clumsy, the
sound is terrible!  I think the tape adapter levels is set too high for the
tape head, sounds like analog clipping!

Anyways, I'm deciding to go with a in-car MD/CD solution.  I've looked at
the few CD/MD combo units like the JVC MX3000, or the Panasonic and Alpine
units, and while they are ideal for my situation (flexibility, I don't
really need a changer), for the cost, I can get either a MD head with a CD
changer or a CD head with a MD changer.

I'm more inclined to go with a MD head with a CD changer given the fact
that CDs are so readily available here in Canada as opposed to MDs.
However, are there any CD changers that don't have that annoying 10sec disc
change delay ?  I would think that since most of these CD changers have
shock memory, that they could change to the next CD while the buffer is
being played out like the MD changers ?  If so, please let me know.
If such a thing doesn't exist, I'm more tempted to go with a CD head with a
MD changer.

Anyone know whose ATRAC the non-Sony units use ?  Also, which CD heads are
able to play CDRs properly ?

thx,
Wayne

p.s. Are the Sanyo MDR-4s all gone ?  What are the opinions of people who
purchased this ?
