SoundConnect 2 TM is a compact and rugged USB controlled microphone power supply and conditioning
amplifier. It can power either one or two microphones, so it is a great choice for audio test applications
where two microphones need to be powered simultaneously, for example headphone testing, stereo
measurements, or anywhere you need a reference microphone as well as your input microphone.
