The new-generation 10-channel intelligent mixer features an extremely high signal-to-noise ratio, delivering clear and natural sound quality. Its built-in large-capacity microcomputer ensures smoother process control during meetings. It can achieve arbitrary priority functions. With excellent expandability, users can connect multiple hosts in series according to microphone requirements, while the function settings of each host remain unchanged. Equipped with built-in limiter, equalizer, and digital feedback suppressor, it can prevent feedback caused by multiple microphones being turned on simultaneously.

Functions include 10-channel intelligent mixing, feedback suppression, equalization, automatic limiting, phantom power supply. It supports central control and can be directly connected to cameras for camera tracking.

I. Product Features

Equipped with 10 balanced input channels, which can be connected to microphones.

Built-in 48V phantom power supply, with a main phantom switch on the rear panel. Independent 48V phantom power switches for each channel, accessible by opening the chassis, facilitating connection with various microphones.

Features treble and bass adjustment as well as gain adjustment functions.

Each input channel is equipped with an automatic voice gate, and the threshold level of the voice gate can be adjusted via the MANU control. Only the channels with signal input are automatically activated.

Automatic Limiter Function: Built-in automatic limiter, which adjusts the total output level via the COMPRESS control. When multiple microphones are used simultaneously, it can prevent feedback caused by increased gain of the overall system.

Feedback Suppression Function: Built-in digital frequency shifter with a frequency shift of 5Hz, offering high fidelity and excellent feedback suppression effect. It can be switched via the "SHIFT/BYPASS" control.

Built-in microcomputer: Arbitrary priority functions can be set via the DIP switches on the front panel, with no limit on the number of priority channels. When all DIP switches are in the OFF position, it is in the free speech mode, allowing 10 microphones to speak arbitrarily. When a certain DIP switch is set to ON, the speaking level of other microphones will be automatically attenuated by -10dB when the corresponding microphone is activated. PC software supports modes such as free speech, sequential speech, and designated speech.

Up to 10 units can be connected in series to form a conference system with 100 microphones.

An additional auxiliary input is provided for background music input.

Equipped with balanced output and one set of auxiliary output.

RS232 and RS485 interfaces for easy connection to central control systems and cameras. Supports PELCO and SONY VISCA protocols.
