High end intelligent 8-way mixer

AVA-781

Product Description:

The conference system composed of intelligent mixer is easy to operate, high fidelity audio amplification circuit, and the sound color is round and clear. At the same time, it can eliminate or weaken the feedback in these places without changing the sound quality. Optional microphone with all kinds of use! RS-232 port can be connected with central control or industrial control equipment, and can control each microphone on or off to realize remote control of microphone switch. The rear panel is equipped with external control output terminal, which can be connected with video tracking controller mv-32 to form a video conference system.

characteristic:

*8-channel microphone signal input, automatically open the channel glottis with signal input, and the action level can be adjusted automatically.

*Each channel can be set as priority speech. When speaking in the priority channel, the speeches of other channels will be automatically closed.

*Each circuit is equipped with high-efficiency low-frequency attenuation circuit (130Hz) to effectively suppress the noise of low-frequency jet sound.

*2-way lotus head port auxiliary audio input and output

*RS-232 external control port is used to expand the application capability of mixer.

*Support up to 16 mixers for extended applications, totaling 128 microphone signals

*The external control output port can be connected to the video tracking controller mv-32 to form a video conference system.

*Noma function: (number of open microphone attached) automatically adjusts the output level, which can prevent howling due to the increase of the overall gain of the system when multiple extensions are used!
