Pre Micro PRE-01

The optional, battery-operated, PRE-01 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 and MIC-02. 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 two standard 9V batteries or with an external DC power supply. PRE-01 substitutes the 3381/A preamplifier.
