Product Desciption
professional audio power amplifier intercom system pa amplifier
Features of professional audio power amplifier intercom system pa amplifier
2U standard 19-inch industrial chassis, ergonomic design, sophisticated technology, filling with the high-grade temperament;
3 channels of MICs, 2 channels of audio inputs, an auxiliary audio output;
Forcibly cutting priority function, Mic 1 has the highest priority, the other channels have second priorities;
2 channels of Mic Line Inputs (sensitivity of MIC2/MIC3 channel line input is 775mv);
Mic and Aux have volume control knob and treble, bass tone control knob;
Amplifier output comes with four partitions, you can select the partition state;
The device has a good short circuit, overheat, overload automatic detect and protect function, the indicator will light to warm, warning buzzer will ring to alarm;
Linking two machines can achieve independent volume control for each channel for eight partition, as well as three machines can achieve independent volume control for each channel for twelve partition ,and so forth;
2 kinds of power output modes: constant voltage output 100V, 70V and constant resistance output 4~16Ω.,4 partition output modes: constant voltage output 100V.
