Re: MD: Plug-in power

2000-12-28 Thread Leon K




Hi there,

Plug-in power means that the mike itself doesn't have any power source, but feeds off 
the recorder.

I'm not sure about the other questions. :)

 Hi! 
  
 I'm new to this list and very thankful I've found it. 
  
 I have a few questions about the MD-SR60 portable MiniDisc player/recorder. 
 I got one for Christmas and am unfamiliar with this type of media and 
 plug-in power. 
  
 1.  What is plug-in power and how does it differ from the standard 48v 
 phantom power used in condenser microphones? 
  
 2.  Will a normal dynamic microphone work with this MD recorder?  I'm told 
 that the MD sends power to the microphone...what kinds of microphones could 
 be harmed by using them with this model MD?  What types of microphones will 
 hurt the MD? 
  
 3.  Is it possible to use a microphone powered by a battery?  If I take out 
 the battery, will the microphone be powered by the MD and work just fine? 
  
 4.  Can anyone recommend a mic under $100 that will be compatible with this 
 model MiniDisc recorder?  Would the Sony ECM-MS907 be ok? 
  
 5.  I have tried a normal dynamic microphone with an XLR to 1/4" cable. 
 When I use a tip/sleeve 1/4" to 1/8" adapter (to go from the mic cable into 
 the MD recorder) I do not get any signal into the MD recorder.  When I use a 
 tip/ring/sleeve adapter, I do get signal but when I connect it, I hear an 
 electrical popping from the microphone.  Can anyone explain what is going on 
 here? 
  
  
 Thank you for your time.  I would appreciate a response as soon as possible 
 as I am going out of the country in two days and need this MiniDisc recorder 
 to be functional.

It is about 3 volts or so and provides power to run a small condenser
mike.  It will not run a mike that requires 48v phantum power.

None will harm the MD, and none will be harmed. They just won't work
very well, but will not be damaged.


 3.  Is it possible to use a microphone powered by a battery?  If I take out

You can use a battery powered mike.  I don't know if it will work
without the battery though.

 
 4.  Can anyone recommend a mic under $100 that will be compatible with this

If you want to try making one, I designed one the works very well.  It
costs $10 for the parts to build it.  Here are the instructions
http://www.tir.com/~liteways/Mandolin.html#Microphone or you can buy a
similar one from the sound professionals for $40 or 50 bucks.  THere is
a link on that page for my mike.
 
 5.  I have tried a normal dynamic microphone with an XLR to 1/4" cable.

The MD has a tip/ring/sleave stereo jack.  your XLR to 1/8 mono will
probably short out one of the channels and at best would only give you a
mono recording.  at the worst it wil short out both of them andyou won't
get anything.  When you connect a tip ring sleave adaptor, I suspect the
plug in power is feeding into the dynamic mike causing it to act as a
speaker.  The current is too small to hurt the mike, but it reduces the
effectiveness of the mike too by biasing the mike with a foreign
current.  It will probably reduce the frequency response.  Your best bet
is to get a condenser mike for it.

 
 Thank you for your time.  I would appreciate a response as soon as possible
 as I am going out of the country in two days and need this MiniDisc recorder

Ok, go to Radio Shack and buy two condenser lapel mikes and a mono to
stereo adaptor. to plug the two mono mikes into, producing a stereo
plugh to go into the md.  Use the batteries that come with the two
mikes.  You can also use just one at a time in a pinch. but it will be
mono.

You might consider a set of our Low Cost Binaural mics.  They seem to be
very popular among budget-concious MD tapers for concerts, lectures,
interviews and ambience.

For details, please see our Web page or send email.
