The Sanyo MCD 3100 is a really nice boombox with MD, CD, & tape, and a
microphone input.

I found an old posting by Oscar Fowler, (04 Jan 1999):

which suggests it was marketed in the UK.

You can add a low cost pre-amp to a home MD deck.  In the US, Midiman
makes a nice sounding, reasonably priced pre-amp: the Flying Calf.
Rolls and many other manufacturers also make them.

This isn't quite right.  The battery box you refer to is not a
microphone pre-amp.  It does not allow you to use the line input when
otherwise you couldn't.  All it does is provide a voltage to either
provide the mic's operating voltage when the recorder can't, or in an
attempt improve its performance.

All current portable MD recorders (e.g., Sony, Sharp, Aiwa) can provide
an adequate voltage to drive the unmodified Panasonic mic capsules used
in ourt Low Cost Binaural microphone set, so in general, you should
rarely need a battery box unless you are recording *extremely* loud
sounds.

If you do use a battery box with unmodified Panasonic microphone
capsules, you'll find that you get *higher* distortion, though the mics
will handle higher sound pressure levels before they overload.

Using the battery box actually increases microphone self-noise unless
the microphones are modified.  For example, our Core Sound Binaural and
Core Sound Stealth Cardioid microphones are modified so that they have
lower self-noise, more than 20 dB more dynamic range, much lower
distortion at high sound pressure levels, flatter frequency response,
and less potential for mic pre-amp overload.  They require the use of
the battery box that comes with them.

I hope that this helps!

Ever since boom boxes started coming with CD players in them, Line In jacks
are rare. Maybe they exist on high-end boom boxes, but other than that,
their absence reflects the fact that they had been there mainly for
connecting portable CD players.

As for direct reording with a mic and MD portable--several years ago I
dragged out the only mic I had at the time---a consumer-grade Radio Shack
mic!--plugged it in to the original MD, the MZ1, and recorded a lot of
background sound effects for a recording project. The results were
excellent. I believe that your wife would be pleased with the results, even
if you did use the Mic In jack.

But, don't use a mic that needs what is called "phantom power."

I have never run into trouble with background noise from the mike input
of a minidisc recorder.   The only extraneous noise I have ever picked
up using my plug in mike 
http://www.tir.com/~liteways/Mandolin.html#Microphone 
has been when I recorded extremely quiet conversations, or tried to
record the sounds of nature.  Only in these quiet setting, did  I have
to turn the record level up high enough that I could hear a quiet tick
sound every few seconds that sounded like a clock ticking only much
slower.  It turned out that the sound is the sound of a portable
recorder's motor starting and stopping the disc as it records.  It is
very rare that you have to turn the level up that high, certainly you
would not hear that recording someone playing music, even on a flute or
soprano recorder.

Those are good folk at Sound Professionals and I recommend them. 
However, you will only need the battery box if you are trying to record
loud bands or rock concerts.

Re: MD: portable MD with mic recording?

2000-05-22 Thread J. Coon


If you use a boom box system, you would have to use a preamp to bring
the mike level up to the "line-in" level.   It works on the home deck
units, the boom box would have to have a Line-in input for that to work.
My guess is that a preamp and boom box would be a little less prone to
being lifted because they are bigger.  


The separate recorder is a lot handier for recordeing though.  If it
were me, I would go with the portable recorder.  You can get a deck or
md boom box to play it back or if youwnat to save a little money you can
just use a tape cassette boom box and one of those cassette tape
adaptors to play the MD through the boom box.  I do it all the time and
also use it in the car the same way.  

For a mike, the one Idesigned works well, and if you are a little bit
handy, or can find someone that is, you can make a stereo mike for about
$10 US,  or somewhere around 2 to 3 quid.  I think someone said Maplins
carries the mike elements.  here are the instructions 
http://www.tir.com/~liteways/Mandolin.html#Microphone

This mike is powered from the portable MD unit, so it won't work with
the preamp and deck/boom box combination.  

The mike has a very good output and the MD units have a wide dynamic
range.  As such you don't need a battery box to record solo or
unamplified music.  If you are trying to record loud rock concerts, the
battery box with a bass roll off filter, will drop the level to where it
can be recorder.  Since I just record band practices, jam  sessions and
amplified acoustic music, I haven't bothered with building a battery box
and haven't needed it.

All the portables have  stereo microphone inputs but the majority of mics are
powered with low voltage. The consequence is that if you plug them to the mic
input, you will have to raise the recording volume and, in that case, you will have
a backgroung noise (caused by the mic input). So, you'd better use mics with a
battery box that allows mics to be plugged to line input (less, less noisy). For
more details, go at www.soundprofessionnals.com .

Hi all!
My wife's a music teacher and needs a portable (not personal) MD system to be
able to replay CDs and MD to classes and individuals - so far, so good. But she
also needs to be able to make reasonable quality, stereo recordings of her
pupils' performances. We can't find a boombox or mini/micro system (if the
latter, we would have to be able to strap it together to move it from room to

system with a separate portable, but this would be more vulnerable to being
