Functional features:
- one priority and three universal inputs (models SM 200 and SM 600);
- interruption of signals from line and universal inputs and broadcasting the signal from the input PRIORITY to the control command;
- faders for each input (models SM 200 and SM 600);
- tone controls for low, medium and high frequencies (in the models SM 200 and SM 600);
- the possibility of switching on sound processors in the channel of low-frequency signal;
- in-line filters of low and high frequencies;
- built-in safety systems of short circuit and overloads on an output
- output signal about standing condition
- switch off the body from the common wire circuit
- soft start regime
- installation attitude in the standard 19 "RACK-racks
