DSP0808 Digital Audio Matrix

The DSP-0808 is a powerful 8-in and 8-out digital audio processor and touch screen operation is used to control interface display. ADI SHARC 4th generation of ADSP-21489 floating-point audio DSP chip provides the supreme performance 400 MHz/2200 MFLOP processor capacity. The ultra-low ground noise pre-amplification circuit, low-distortion analog circuit and 114dB audio AD and DA provide high-quality sound in field. The front panel of the device must be installed with volume display to display all 8 input 8 and output 8-channel volume status; The 5-inch touch screen is used to adjust channel volumes and call 32 audio effect scenes; display the current device IP addresses and the presetting numbers and presetting names used the processor for the administrator’s quick identification and identifying the current processors in the system. The front panel is composed of network connection status indicator and error alarm indicator. The device is connected with Android system and smart phone or tablet PC operation software package is supported.

Powerful DSP processor capacity  
Based on powerful ADSP-21489 and powerful DSP processing capacity and our unique core DSP algorithm, the built-in standalone 16-channel ultra-low-distortion self-adaptable feedback inhibitor, 8-channel noise gateway, 8-channel input compression limiter, 8-channel 8-band PEQ, 8-channel input 48dB slope high-pass-low-pass filtering, 8-channel 1-second time delayer mean that you can set each input audio channel precisely and exquisitely. The 08×08 full matrix mix function mixes any input channels as you like. The 8 output channels are configured with standalone 8-band PEQ, compression limiters, 48dB slope high-pass-low-pass and 2-second time delayer.
Built-in sinewave, pink noise and white noise signal generators store 32 presetting values.

Rich audio channels and control interface
1 TCP/IP telecommunication port, 1 RS-232 telecommunication port, 1 USB telecommunication port. A third-party telecommunication protocol is opened to meet large, medium and small-sized professional audio projects. Applications of public amplification systems for theatre, music hall, remote video conference, stadium, church, conferencing center and theme park are satisfied.

Color touch screen status display
The 5-inch 16-bit true color (64k colors) touch screen is used to adjust volume and call 32 sound effect scenes; the device displays the current IP address, the presetting numbers and presetting names used by the processor. The device is connected to Android system via WIFI and smart phone or tablet PC operation software package is supported.

Easy-to-use control software
The software interface is developed through senior sound engineers and professional tuner’s in-depth communication and commissioning and the operators’ practice. The control software is popular and easily understand and can be operated without reading the operating manual. Each input numeral is directly entered by the keyboard. To get the precise value, such as -12.2dB, directly enter -12.2. Operate the volume bar and press Shift+ selected key and press the up and down keys to attain 1dB step forwards and backwards. As for PEQ, Limiter and such complicated parameter adjustment, these parameters can be quickly copied and pasted. You can finish multi-channel data copying easily and conveniently.

Open RS-232 and TCP/IP telecommunication protocols
A third-party device is used to control volume, call modes and set mute and TCP/IP protocol is used to read level meters in batch before and after mixing for being integrated with a third-party software.
