PRO features

The PRO series is a powerful digital audio processor that uses the fourth-generation ADSP-21489

floating-point audio DSP from ADI SHARC to provide the highest performance 400 MHz/2200 MFLOP

processor capability. Ultra-low noise floor preamplifier circuit, low distortion analog circuit, 114dB audio

AD, DA, provide high-quality sound quality for the site.The front panel of the device must show the

volume status, that can display all the input 8 and output 8 channel volume status; the LCD display

of the front panel can display the current IP address of the device, the current preset number used by

the processor, and the preset name. It is easy for administrators to quickly identify and differentiate the

current processor when there are multiple processors in the system. The front panel has a network

connection status indicator and an error alarm indicator. When a serious error occurs, a red alarm indication flashes.

Can connect with Android system, support smart phone or tablet PC control software package.

Powerful PRO processor capabilities

Based on the super powerful ADSP-21489 super powerful DSP processing capability and based on our

unique core DSP method, we have built-in independent 8-channel extremely low-distortion adaptive

feedback suppressor, 8-channel noise gate, 8-channel input limiter , 8-channel 8-band PEQ,

16-channel input 48dB slope high-pass low-pass filter, 8-channel 1 second delay, means that you can

make precise and careful settings for each input audio channel. 08x08 full matrix mixing,

free mixing of any input channel. Each of the 8 output channels has an independent 8-band PEQ,

compressor limiter, 48dB slope high-pass low pass, and 2 second delay.

Built-in sine wave, pink noise, white noise signal generator. 32 Presets can be stored.
