Microphone Power Supply – SoundConnect

Microphone Power Supply and Conditioning Amplifier

SoundConnect is a microphone power supply and amplifier designed for use with the Listen SCM microphone and also compatible with  reference microphones from other manufacturers including B&K and GRAS. Its switchable polarization voltage (0, 28, 200V) allows it to be used with both traditional and pre-polarized versions of these microphones.

SoundConnect extends the dynamic range of your measurement system by as much as 80 dB from 2.5 µVrms to 50 Vrms. This offers a better signal to noise ratio for your measurements and therefore greater accuracy. It also offers two signal attenuation settings to avoid clipping with highlevel signals.

A stepped level indicator simplifies gain-setting by offering clear visual feedback of the signal level. Cascaded attenuator and amplifier stages ensure amplification linearity with a minimum of noise and distortion. This is particularly useful for measuring low sensitivity microphones, self-noise, and transducer distortion.

SoundConnect features a LEMO input connector, making it compatible with most measurement microphones. It also has a BNC line in, a BNC output, and an RCA output, simplifying connectivity to a SoundCheck system. Its housing is a rugged all-metal construction that can be used in either a horizontal or vertical orientation, making it suitable for harsh production environments as well as the R&D laboratory.
SoundConnect is made in the U.S.A. and is designed to UL and CE requirements.
