DS418E/DS216E/DS214E Digital Loudspeaker Management

Characteristics

High-performance AD/DA DAC chip and high-speed processing DSP chip.
Delay IS for each input and IS for each output.
Input 7-band PEQ and Output 7-band PEQ.
Accessibility Design (Digital lock, Copy, Routing, etc.)
Support USB/RS485 communication
This could apply to different environments.
Friendly and intuitive control interface, control debugging is more convenient.
