PMS125 is 8ch microphone line amplifier configured with a 19 inches 3U size frame.
The Jensen carefully made transformer which it adopted for input and output realizes superior CMRR (common-mode signal rejection ratio) and reliable signal transmission.
Moreover, by the design that careful consideration was accomplished, it shows the best performance with superior S/N, high-quality sound in a studio, a hall, a stadium and every spot such as the broadcast.

The input impedance can choose 150 Ω or 600 Ω.
An input sensitivity level corresponding to each is indicated in a gain trim.
Moreover, it can supply the +48V power for condenser microphones.

+4dBu or -20dBu can set the output reference level with an internal switch.
(in factory +4)

It can cut an unnecessary low frequency noise in implemented 70Hz, a high pass filter of 24dB/oct sharply.

It allows monitoring of the output level to -20 to +3dB in 10 points of LED bar graph.

A make contact by the MOS relay is output in case of trouble to each redundancy power supply unit.

Please refer about the change of input impedance and the gain.
