4 input 8 output PA Speaker Management System Audio digital processor with FIR

Main Features:

• 1. 96KHz sampling frequency, 32-bit DSP processor, 24-bit A/D and D/A conversion;
• 2. Provide USB, RS485, RS232 interfaces to connect to computer PC software, through the RS485 interface, up to 250 machines can be connected, and the distance of more than 1500 meters can be controlled by external computers; and there is a special RS232 serial connection to the central control system control, which is convenient for different occasion application needs,
• 3. It is very convenient, intuitive and concise to directly use the function keys and coding wheel on the panel to set the function or connect the computer to control it through the PC control software;
• 4. 12 kinds of user application programs can be stored in stand-alone or PC control software;
• 5. You can set a password to lock the panel control function through the SYSTEM button on the panel, so as to prevent the operation of idle personnel from destroying the working state of the machine;
• 6. Each input has 31 segments of GEQ+10 segments of PEQ, and output 10 segments of PEQ;
• 7. 2×24 LCD blue backlight display function settings, 12-segment LED display input/output precise digital level meter, mute and editing status;
• 8. The slope of the variable high/low pass filter can be set, among which Bessel, Butterworth can be set to 12dB, 18dB, 24dB per octave, Linkwitz-Relei (Linkwitz) -Riley) can be set to 12dB, 24dB, 36dB, 48dB per octave;
• 9. The parameters of the high/low pass filter can be adjusted independently, which can realize the asymmetric frequency division function;
• 10. Each input/output has delay and phase control and mute settings, the longest delay can be up to 1000ms, and the delay unit can be selected from milliseconds (ms), meters (m), and feet (ft);
• 11. The output channel can also control gain, pressure limit and select the input channel signal, and can simultaneously select multiple output channels to associate and adjust all parameters synchronously.
