Power supply with acoustic interface for outdoor microphones

ZE908 preamplifier power supply [power supply with acoustic interface]

power supply with acoustic interface

The ZE908 power supply with acoustic interface is a preamplifier.

The preamplifier is manufactured by Cirrus Research who are market leaders in noise measurement. It integrates noise measurements into external data logging systems, signal analysers, and data recorders. The acoustic interface outputs to the industry standard 4-20mA, and offers AC or DC voltage outputs. It also offers dB(A) and dB(Z) frequency weightings, and fast and slow time weightings.

The ZE908 preamplifier power supply is designed for the Cirrus MV200F preamplifier and MK170 outdoor microphone units.
