PRO0808 Network-based digital audio matrix
PRO0808 is a powerful digital audio processor powered by ADI SHARC’s fourth-generation ADSP-21489 floating-point audio DSP chip, which delivers the highest performance 400 MHz/2200 MFLOP processor capabilities. Ultra-low noise floor pre-amplification circuit, low distortion analog circuit, 114dB audio AD, DA, provide high-quality sound quality for the scene. The front panel of the device must have a volume status display, which can display the volume status of all input 8 and output 8 channels; The LCD display on the front panel of the device can display the current IP address of the device, the preset number and preset name of the processor in a loop, so that when there are multiple processors in the system, the administrator can quickly identify and distinguish the current processor. The front panel has a network connection status indicator, an error alarm indicator, and a flashing red alarm when there is a serious error.
Powerful DSP processor capabilities
Based on the ultra-powerful ADSP-21489 ultra-powerful DSP processing power, and based on our unique core DSP method, the built-in independent 8-channel very low distortion adaptive feedback suppressor, 8-channel noise gate, 8-channel input voltage limiter, 8-channel 8-segment PEQ, 8-channel input 48dB slope high-pass-low-pass filter, and 8-channel 1-second delay mean that you can make precise and careful settings for each input audio channel. 08×08 full matrix mixing, realize free mixing of any input channel. Each of the eight output channels has an independent 8-segment PEQ, a voltage limiter, a 48dB slope high-pass-lowpass, and a 2-second delay.
Built-in sine wave, pink noise, white noise signal generator. 32 Presets can be stored.
Rich audio channels and control interfaces:
1 TCP/IP, 1 RS-232 port, 1 USB communication port, open third-party control protocol. It can meet the needs of a variety of large, medium and small professional audio projects. It can meet the application needs of theaters, concert halls, remote video conferences, stadiums, churches, conference centers, theme parks and other public sound reinforcement systems.
LCD screen status display:
The 1602 LCD screen on the front panel displays important information such as IP address, current preset name, and usage time
Easy-to-use control software:
Through senior sound engineers and professional tuners, we have in-depth communication with the operation habits of debugging and application personnel, and developed a software interface that conforms to industry applications. The control software is easy to understand and can be quickly operated without manuals. Each input value can be directly entered on the keyboard to get the exact value you want, such as – 12. 2dB Direct Input – 12. 2。 The volume fader operates Shi ft + to select the channel, press the up and down arrow keys on the keyboard, and you can achieve 1dB steps and step decreases. For complex parameter adjustments such as PEQ and Li miter, the parameters can be quickly copied and pasted, and you can easily realize multi-channel data copying, which is convenient to operate.
Open RS-232, TCP/IP communication protocols
Realize third-party equipment to control the volume, call mode, set mute, and be able to read the pre-mixing level meter and post-mixing level meter in batches through TCP/IP protocol, which is convenient for third-party software integration.
