    Built-in telephone coupler input and output ports to convoke remote multi-party telephone conference

    LCD is installed on the control panel to display system setting and operating status

    Various conferencing modes of “FIFO”, “limit” and “free”

    The limit switch for “number of simultaneously operating microphones”, and “1 microphone for speaking”, “6 microphones for speaking” or “all microphones for speaking” is optional.

    Background tone adjustment, telephone input and total volume output adjuster are available.

    Each system host is connected to 90 microphone units (or 60 microphone units with loudspeakers), which are hand-in-hand connected in parallel in 3 channels.

    Parallel audio output and 6.3 jack output ports are configured.

    Dual-track background music input port plays conference background music for microphone with built-in speakers.

    Conference recording output port

    Efficient and stable digital power supply, more environmental protection and less background noise
