Digital Audio Processor

GONSIN Digital Audio Processor adopts the fourth generation audio DSP chip, hence now it is equipped with strong DSP processing power. Furthermore, the unique core DSP method and the design for lower noise as well as lower distortion provide high-quality sound quality to the site. The updated Digital Audio Processor not only meets the operating requirements of professional audio projects of all sizes, but also meets the application requirements of various social occasions (Theatre, concert hall, remote video conference, stadium, church, convention center, theme park, etc.)

Features
High-performance floating-point DSP processing chip.
Balance XLR 4/8/16.
All the input channels support MIC input,with 48V phantom power soft switching ( for GXDSP1012/13/14 only ).
All the input channels are with Gain Control, Noise Gate, Automatic Feedback Suppressor, High and Low Pass Filter, Parameter Equalizer (16 segments), Compressor, Delay Timer and Input Marshalling Controller.
8/16 balanced-line electrical levels for output voltage
All the input channels are with High and Low Pass Filter, Parameter Equalizer (16 segments), Compressor, Delay Timer and Input Marshalling Controller.
4/8/16 channels for automation
Dynamic range:114dB, ADC, DAC
Built-in signal generator: sine wave signal, pink noise, white noise.
The front panel carries with input and output volume display lights, error warning light.
The panel carries with LCD display monitor, helps display the system status directly.
Be open to RS-232(for GX-DSP1012/13/14 only)and TCP/IP, the third-part calling-control could be achievable.
Enables to output camera tracking code, be conducive to realize camera linkage function through the third-part calling-control.
Preset-scene function that is supportive to 32 sets scenes, can be adjusted by RS-232(for GX-DSP1012/13/14 only)and TCP/IP.
Optional function: AEC (for GX-DSP1012/13/14 only).
Can take control through Ethernet, the operation interface is visualized and the setting is easy and efficient.
