Click to enlargeThe Power Module Type 12AP is a power supply and conditioning amplifier for simultaneously powering a preamplifier for a condenser microphone and an amplifier for a loudspeaker (suitably, any sound source using a loudspeaker/earphone/coupler). By design, it will avoid system-generated noise, e.g. from ground loops.

It is remotely controlled entirely via its RS232 interface and, for this purpose, is delivered with a control program for Microsoft Windows®.

In a measurement set-up, the Type 12AP straddles the paths of both the signal sent out to the loudspeaker and the resulting acoustic signal picked up by a condenser microphone fitted to the preamplifier. In both cases, its set-up for handling these signals independently comes under external control.
