Hot Sale High Performance 4 Channel DSP Audio Processor for conference,education
Introduction:
DSP Series are equipped with several core technical features to facilitate the work of audio engineers. DSP-based remote audio hardware is routed, processed and controlled via computer. This Manual mainly introduces the techniques used to achieve the goal.
DSP Controller is a Windows-based application, which is used to conduct configuration and control on DSP hardware. DSP Controller has 16 built-in presets, and the modules and sequences for each preset can be flexibly designed in accordance with the designer's requirements. After the design is finished, it can be saved for future use. The sequences and
parameters of DSP Controller's built-in processing modules accord to most of the application scenarios without any change.
DSP Controller is a full-featured application including the parameter adjustment and peripheral accessory settings of all modules, such as RS232, RS485, click-and-drag panel configuration and Dante network audio control etc. The most interesting part is the user interface, which allows the engineer to customize user interface so that the integrator can editit or the onsite technicians or end users who have no idea of relevant techniques can operate it.Superior safety functions make it possible for the end users to access to the controls allowed by the engineer or designer.
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.
