Description
  •  Based on proprietary digital audio processing and transmission technology.
  •  Equipped with a 4.3-inch touchscreen displayfor easy operation and parameter adjustment; AFC touch buttons and function status indicators on the panel.
  •  Integrated AFC feedback suppressionwith two algorithms (notch filter and frequency shift), automatically detecting feedback points and setting notch filters. Supports 12 fixed points and 12 dynamic pointsfor effective feedback elimination.
  •  Automatic mixing function, including gain-sharing and threshold-based auto-mixing.
  •  Automatic gain control (AGC)to maintain microphone volume within a dynamic range.
  •  Supports microphone voice activationwith adjustable tracking threshold, enabling camera tracking when a microphone is active.
  •  31-band graphic EQadjustment on the output.
  •  Supports four 6-pin interfaces, expandable up to 128 units.
  •  Equipped with two network portsfor connecting a wireless AP and conference host. Uses network protocols to integrate with the digital conference hostfor audio data transmission.
  •  Provides one balanced XLR outputand one unbalanced RCA output.
  •  One EXTENSION interfacefor connecting to the digital conference host expansion port.
  •  One RS-485 communication port, supporting camera control for tracking functions.
  •  One RS-232 communication port (camera tracking)for integration with central control systems or camera tracking hosts.
  •  One RS-232 communication port (speech-to-text)for connecting to a speech transcription server.
  •  Built-in 100Mbps network communication, with SSRAMand 10/100Mbps Ethernet switching functions. Provides two network interfaces, each supporting IEEE 802.3, IEEE 802.3u, and IEEE 802.3xstandards.
