8x8 Digital Audio Matrix (with Echo Cancellation)
EDT0808A

The EDT0808A is based on the super-powerful ADSP-21489's super-powerful DSP processing power, and on our unique core DSP method, which implements a built-in independent 8-channel very-low-distortion adaptive feedback suppressor, an 8-channel noise gate, 8-channel input compressor, 8-channel 16-band PEQ, 8-channel input 48dB slope high-pass-low-pass filter, and an 8-channel 1-second Delay timer means you can make precise, careful settings for each input audio channel. 8x8 full matrix mixing for free mixing of any input channel. 8 output channels have independent 16-band PEQ, compressor limiter, 48dB slope high-pass-low-pass, 2-second delay timer.


Built-in Sine Wave, Pink Noise, and White Noise signal generators. Can store 32 Pres et. Rich audio channel and control interface.


1 TCP/IP communication port, 1 RS- 232 communication port, open third-party control protocol. Can satisfy various large, medium and small professional audio projects. Can meet the theater, concert hall, remote video conferencing, sports venues, churches, conference centers, theme parks and other public sound reinforcement systems and other aspects of the application needs.


Easy-to-use control software

We visit experienced senior sound engineers, professional mixers, in-depth communication debugging, application staff operating habits, developed in line with the industry application of the software interface. The control software is easy to understand and can be operated quickly without manuals. Each input value can be entered directly into the keyboard to get the exact value you want, such as - 12. 2dB directly into the - 12. 2. volume fader operation Shi f t + selected channel, press the keyboard up and down arrow keys, you can realize the 1dB step, step down. For PEQ, Li mi t er such complex parameter adjustments, the parameters can be quickly copied and pasted, you can easily realize the data copying of multiple channels, convenient operation.


Open RS-232, TCP/IP communication protocols

Realize the third-party equipment to control the volume, call mode, set mute, able to read the pre-mix level meter and post-mix level meter in batch via TCP/IP protocol, easy for third-party software integration.
