Microphone preamplifier PRE-01
The optional, battery-operated, PRE-01MK2 microphone preamplifier satisfies the needs of laboratory measurements, performs A-weight filtering and drives long cables to the PC.
The microphone preamplifier PRE-01 has been designed to match Audiomatica’s microphones MIC-01, MIC-02 and
MIC-03. It is particularly useful when the microphone has to be operated far from the analyzer or when weighted measurements are needed. PRE-01 powers the microphone connected to its input with an 8.2V phantom supply
and adds a selectable weighting filter (A or B or C); also available there is a 20 dB gain stage.
The unit is operated with a single standard 9V battery or with an external DC power supply.
