UltraSoundGate 1/4" Mic Power Module with 7-pin LEMO 1B input connector |
part # 40017 | |
|
The 1/4" microphone power module allows to connect 1/4" (or 1/8") measurement microphones directly to the UltraSoundGate xx16x units, which can greatly simplify the use of measurement microphones in the field (otherwise a separate power supply module / conditioning amplifier would be required). It is powered from the UltraSoundGate base unit and includes a low-noise preamplifier and a switchable 15 kHz high pass filter.
