Product Description

 combined public address amplifier 550W

Application:
Integrated Amplifier with five power division outputs;
To provide amplified signals for regional PAS, suitable for large,medium,small PAS and still needs power partition

Features:

2U standard 19-inch industrial chassis, ergonomic design, sophisticated technology, filling with the high-grade temperament;
Touchable button operation, digital display the volume and radio frequency;
1 channel of microphone input, 1 USB and SD card MP3 inputs, 2 microphone, two lines of audio inputs;
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);
Support radio, MP3 data formats and audio line play;
amplifier output comes with five 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;
2 kinds of power output modes: constant voltage output 100V, 70V and constant resistance output 4~16Ω.,5 partition output modes: constant voltage output 100V
