每通道的輸入口可以根據輸入話筒的不同靈敏度來選擇不同的輸入電平，單獨來調節通道的增益來實現視頻會議系統。
本機具有48V幻像電源供電系統，有開關控制選擇，以適應幻像和非幻像話筒輸入的需要。
配備RS-232接口，可連接中控及外部控制器，方便控制每通道的攝像預置位，還具有強大的擴展能力。
本機具有平衡式輸入插口。
任何種話筒都可以實現視像跟蹤

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
