Phantom Power (+48V) != bias voltage (+5V) Although they function similarly in that the mics that need them DON'T work without them. A bias voltage imples a high noise floor. Especially when you consider the RFI nightmare that exists in the internals of a computer. So not all cards provide it. http://www.epanorama.net/circuits/microphone_powering.html http://en.wikipedia.org/wiki/Phantom_power http://en.wikipedia.org/wiki/Electret_microphone ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
