DP808E 8×8 Audio Matrix

DP808E 8×8 Audio Matrix

  • Dual-screen Interaction + Convenient Control: Equipped with two 2.0-inch LCD screens—the left one is for device parameter configuration and viewing, while the right one displays channel levels. Panel knobs allow independent adjustment of volume and mute for each channel. Installation software and user manuals are built-in, eliminating the need for optical discs.
  • Rich Interfaces + Powerful Expandability: Features 8-channel analog balanced inputs and outputs, and supports multiple interfaces including USB, RS232/485, Ethernet and GPIO. It enables control via computer, Android APP or central control system, and supports multi-device network management as well as USB recording and broadcasting.
  • Professional DSP + Security Functions: Integrates a full range of audio processing functions such as AFC/AEC/ANC, with 15-band PEQ for inputs and 10-band PEQ for outputs, plus 2000ms delay per channel. It comes with 60 preset memory slots, camera tracking protocol support and archive locking function to ensure project technical security.

Main Features:

1. Dual 2.0-inch LCD screens: the left screen supports functions such as configuring device name, device presets, device IP, input volume, output volume, input mode, and checking device version; the right screen displays the level fluctuation of each input and output channel.

2. The panel is equipped with knobs, which can independently control the volume level and mute function of each input and output channel.

3. The device requires no optical disc, with built-in installation software and product user manual, eliminating the troubles caused by lost installation discs and confusion among multiple software versions.

4. 8-channel analog balanced inputs and 8-channel analog balanced outputs, with a maximum undistorted input and output level of 17 dBu (5.48 Vrms).

5. Each input channel is equipped with a microphone preamplifier, featuring adjustable gain from 0 to 40 dB in 1 dB steps, and comes with 48V phantom power supply.

6. Expandable USB interface, which not only enables computer software control and USB sound card transmission, but also supports USB recording and broadcasting functions.

7. Bidirectional RS232 interface, RS485 interface, standard Ethernet control interface, and 8-channel programmable GPIO control interface (customizable input and output).

8. Network interface for computer software control and central control functions; multiple devices can be managed simultaneously via network connection.

9. DSP functions include: AFC (Acoustic Feedback Cancellation), AEC (Acoustic Echo Cancellation), ANC (Active Noise Cancellation), AGC (Automatic Gain Control), AUTO MIX, MATRIX MIX, noise gate, PEQ (Parametric Equalizer), delay, PHASE filter, high-pass & low-pass crossover, compressor, and limiter.

10. 15-band PEQ for inputs and 10-band PEQ for outputs.

11. 2000ms delay for each input/output channel.

12. 512-tap FIR for each output channel.

13. Full-function matrix mixing, built-in automatic camera tracking function, supporting camera control with PELCO-D, PELCO-P and VISCA protocols.

14. 60 preset memory locations.

15. Supports control via wired controller and Android APP network control.

16. Supports archive locking and hiding of setting parameters to ensure project technical security.

17. Intuitive, graphical software control interface, operable in Windows system environment.
