No battery no preamp necessary -- it?s a dynamic microphone. It will work with any recorder cassette, minidisk, plextalk -- it does not care. I get excellent recordings with it just plugged straight into the microphone input of all of my plextalks. Still if you want extreme sensativity and a better frequency response you could ask your sales person to recommend a good omni condenser that will run from an internal battery rather than looking to the recorder for its phantom power. I would not recommend the use of a preamp because you would get the gain but not the frequency response increase.

Interesting that one kind of microphone could have been around for such a long time. You'll probably have to use a preamp on this one though? -----Original Message----- From: ptr1-users-bounce@xxxxxxxxxxxxx [mailto:ptr1-users-bounce@xxxxxxxxxxxxx] On Behalf Of Frank Cuta Sent: 19 January 2009 01:55 AM To: ptr1-users@xxxxxxxxxxxxx Subject: RE: Omnidirectional microphones to use with ptr2 Andre, I actually do not know of an omni directional condenser microphone although I am sure they exist. The industry standard omni dynamic is the electro voice 635A. It is very sturdy and has reasonable fidelity for voice. It has been arounde for about 50 years and many of the great live recordings from the early 60's were recorded with this microphone or its directional brother the electro voice RE15. I have been buying the 635A on ebay for about $60 although they still sell new in the box for over $100.

I know that for this reason you can simply sit in the audience with your ptr2 and record through the internal microphone. But should you wish to use an external omnidirectional microphone, can anyone perhaps recommend a good external omnidirectional microphone for this purpose? I am speaking of a situation where you will not be able to use e.g. a boundary microphone with an external mains phantom power supply. Andre Internal Virus Database is out-of-date. Checked by AVG.
