D6574Ⅱ is an 8-channel digital conference mixer, which could be applied in profession sound reinforcement, public address and recording fields. Built-in priority speaker mode allows multiple microphones to speak simultaneously without interfering with each other. Noma function allows the system to automatically adjust the output level as the gain of the channel is increased, effectively preventing the noise. It supports multiple I/O configurations to extend multiple devices. If the rear panel is equipped with an external control output terminal, the camera can be configured to make video conference system according to the control protocol. In addition, it supports multiple mixer extensions with up to 16 expansion units.
