4 In 4 out Mini DSP audio processor with AFC/AEC/ANS/AGC/ANC/Ducker/RS 232 and camera control
The MU44 audio processor is a freely designed audio processing and control system.It adopts advanced DSP processing technology, has a new automatic mixing, Feedback elimination,Echo cancellation,Noise cancellation etc, targeted to solve various practical problems in the application scene
Main Features:
- Analog input channel: 4
- Analog output channel: 4
- Built-in two in two out USB sound card, support music playback, recording and soft video conferencing ,Such as: ZOOM, Tencent Conference, Dingding conference, etc.;
- Two channels independent AEC, tail time: 512ms, convergence rate: 60dB/S, echo cancellation amplitude: 60dB; Independent channel AFC (feedback suppression), using notch algorithm, sound transmission gain increase amplitude: 10dB; Noise suppression (ANS), signal-to-noise ratio increased by 18dB
- Eight-stage English parametric equalization provides five filter choices:
- Parametric, Lowshelf, Highshelf, Lowpass, Highpass;
- Provides customized operation interfaces for terminal users. A maximum of 30 devices can be managed on one interface.
- With the central control function, support RS232, RS485, UDP three control modes, can be the system power, signal switching, environmental control, audio control and other overall control, to achieve a key to open the system required functions.
It can use together with the control panel:OLED SCREEN PANEL:
OLED screen consists of a 1.3” OLED screen and a knob. OLED screen display strategy is classified according to menu. There are totally three types of menus including menu, buttons and presets. Double click a OLED screen in design area of the screen to enter its detailed setting as shown below. Click "add menu" to pop up menu selection box, choose corresponding menu and confirm it. After finishing the setting of software menu configuration, click toolbar download icon to download the configuration to panel hardware. Operation steps of panel:
1. Display panel name and IP address on main interface and turn the knob left or right to switch
menu.
2. Press the button on the knob, and the second row on menu interface starts to flash, which
indicates that it enters edit mode.
3. Turn the knob left or right to change value.
4. Press the button on the knob again to edit mode and go back to menu mode.
