hi all.....
wanting to build an external power supply with multiple voltage
drops(connections for different power needs) Has anyone done this? I know
Eco Charge is the place .....but don't have the $200 so I think I can build
this for a lot less....Here's what I need.....
Equipment to power:
A Sony D8 and SBM1......both are 6volt units.....
Either a Nak M100 Mixer......10v....or small preamp???? open for
suggestions???????
Would love to run all off one battery.....I picked up a 12v 7.0ah battery
for starters ...now I'm hoping some kind soul has figured this out and can
help me out or at least point me in the right direction....All help Much
appreciated...
Please e/mail with responses.....Thanks In Advance... ptivnan@ziplink.net

I try to be unbiased. If you want to know what they look like, how well
they're built and how they sound, I'd be glad to share what I know.
We work hard to keep Core Sound mics better than our competition so we
regularly evaluate other folks' mics. If asked, I can compare what the
Soundman OKM IIR offers, feature by feature, to what we offer in the
same price range.

There's no bias problem. Our 7-Pin-Coax-I/O cable will work fine with a
single jumper that the folks at Zefiro can tell you about.

Subject: Re: Moving WAV files between systems
Date: Fri, 15 Jan 1999 20:35:52 +0100
I'm greatly interested in this topic as I often need to store or transfer
large amount of sound data.
Storage and transfer are two very different things, though they often share
the same requirements and problems.
Just about this topic I recenty asked in this list information about
radio-links to transfer spdif data and about wireless USB hubs.
Why ? for my research activities I would like to transfer digital audio
data among systems not physically connected, for example on two different
sailing boats... while recording underwater sounds from marine mammals.
Now, back to the transfer rate problem:
I tested the following system:
a P200 desktop PC with a PCI 10baseT ethernet card connected to a P233MMX
notebook with a pcmcia 10baseT ethernet card (pcmcia, not CardBus!). Both
10Mbps ethernet cards, both running w98.
I transferred a 210MB file among the above systems and, with a stopwatch, a
measured the file transfer time:
desktop --->> notebook 410 seconds on average
notebook --->> desktop 350 seconds on average
in both cases I got a transfer rate well below (less than half) the
expected 10Mbps!
Maybe 10 Mbps means 5Mbps in a direction and 5 in the other direction ?
Or these poor performances depend by the slow pcmcia bus (typically no more
than 800kbytes per second can be transferred).
other tests:
desktop, copy on the same IDE HD, different partition 115 seconds
desktop, copy on a different IDE HD 65 seconds
N.B. these results strongly depends on the controller and on the HDs.

You'll find answers to all of your questions on the MD-L mailing list
and at their archive site. You'll find a link to the MiniDisc community
Web site on our Web page.

Most MD machines have sampling rate converters built into them to
convert input data streams to their 44.1 kHz rate.
All but the very oldest portable MD recorders only have a digital input,
no output; home decks have both. From a home MD deck you can record to
a CD-R from an MD directly, in the digital domain.
Keep in mind that, while portable MD recorders are very small &
convenient, and their sound has improved tremendously in the last two
years, they still compress their data. Under some circumstances you can
hear the artifacts of the compression process. In general though, MDs
sound very good. Incredibly good, if you consider their price (around
$250).
Also, the longest blank MD is 74 minutes.

You'll find this information on the Web page I mentioned above.

This is incorrect. The data on CDs is indeed encoded in physical holes,
or pits, etched into the aluminum medium. But those pits will not "fill
in" - that would require some sort of external force to redistribute the
material, such as an applied voltage which results in electromigration and
redistribution of thealuminum. There is no applied force to a CD, except
its rotation.
The more likely degradation mechanism is oxidation ("rusting") of the
aluminum. As more of the Al turns into Al2O3, its reflectivity changes,
and the disc no longer reflects the laser properly. The source of the
oxidation is oxygen (duh) and moisture, which diffuse through the plastic
over time. Rick's relative is likely working on a plastic with very low
permeability of oxygen and moisture.

Have you tried using a regular CD lens cleaner? My friend's player (a Sony
changer that apparently let in dust too easily) played some CDs flawlessly,
but others with skips, every time. After using a regular $12 lens cleaner,
it played all CDs without skips! I can't explain why it would do this,
except that the troublesome CDs were harder to read, and the extra dust
just pushed it over the edge a little. I don't know how new your DVD player
is, but I'd give it a try--it's worth having a lens cleaner anyway, IMO--if
for no other reason than to rule out the possiblity of dust.
BTW, I'm assuming these are 74 minute CD-Rs, no? Have you tried other
brands of 74-minute CD-Rs to see if they also had problems? (Kodaks--or at
least the ones made before a few months ago--are less reflective than most
other CD-Rs. But that shouldn't cause problems with a dual pickup system
like Sony's.)

Well.....if I play a DAT with scms of 10 on the D5, and use the
S/Pdif out....my other consumer decks will NOT clone. Is this a
matter of supporting scms?

For Sale: HHb PDR-1000 Portadat with Eco-Charge Gamma Pro two-battery system.
Will sell with or without the eco-charges.
This unit has low hours and has been well cared for. It was recently
serviced, cleaned, and aligned by Dennis Cherney / Next Generation, an
authorized HHb service center and has a long life expectancy. I no longer use
it enough to justify my cost investment, and recently switched to a Sony M1
for size/stealth reasons. It pains me to part with this deck, but finances
dictate the necessity. For details and specs on the unit, please see:
http://www.hhb.co.uk/pdrus.htm
Selling price is $2250, including c.o.d. shipping for the following package:
---HHb PDR-1000 Portadat machine
---One MHB220 Rechargeable Nickel Metal Hydride battery pack (~2hrs.,
internal/removable)
---RB110 12v DC power supply / 2 bay charger
---Owners manual and original packaging
---Eco-Charge Gamma Pro system (two external 12v rechargeable batteries
w/cordora cases, one intelli-charger, and cable for connecting battery to
deck)
Will consider sale without eco-charge system.

This has nothing to do with anything. The problem is that DVD players use a
shorter wavelength laser, enabling the higher density of DVDs. This laser
can usually read CDs, but add in the problem with the reflectivity reduction
of CDRs and you get no music 8-(
The Sonys have two lasers. One the correct wavelength for DVDs, one the
correct wavelength for CDs / CDRs.
BTW, I bought a Sony S300 DVD player - partially for this reason - and
although it will play CDRs, it is problematic. It will deal with Mitsui,
Verbatim, TDK, and most other blue disks, but does occasionally skip, and it
won't even touch the green or gold disks.
BTW, my Sony ES car stereo also has problems with most CDRs (it loves
Verbatims and Mitsuis). Anyone notice a trend here?
My recommendation is don't count on any DVD player as your primary audio CD
player. At least not yet.
