产品描述
每通道的输入口可以根据输入话筒的不同灵敏度来选择不同的输入电平，单独来调节通道的增益来实现视频会议系统。
本机具有48V幻像电源供电系统，有开关控制选择，以适应幻像和非幻像话筒输入的需要。
配备RS-232接口，可连接中控及外部控制器，方便控制每通道的摄像预置位，还具有强大的扩展能力。
本机具有平衡式输入插口。
任何种话筒都可以实现视像跟踪

The SV-MA10 intellectual meeting audio mixer is applicable for all sorts of meeting rooms,
multifunctional halls and reporting conferences. There is an advanced CPU processor and a
RS-232 interface, which can be connected to the computer or central controller. Expanding
serial connection is supported, and the cameras can be controlled through cooperation with
the central controller to form a video meeting system.
The input electrical level of input port of each channel can be chose according to the different sensitive of the microphones, and the gain of each channel can be adjusted to actualize the video meeting sytem.
The unit has a 48V phantom power system with switches to choose phantom microphone input or non-phantom microphone input.
There is a RS-232 interface to connect to the central controller and external controllers to easily control the camera preset positions of each channel, and the interface also has a powerful expanding ability.
The unit has a balanced input socket.
The video tracking can be actualized for any types of microphones
