Product Description

  • Equipped with the latest ADI fifth-generation chip, 64-bit high-speed dual-core DSP processor. ● The music channel features a 9-band PEQ stereo equalizer and automatically recognizes optical digital audio input.
  • The microphone has a 15-band PEQ for individual adjustment, a fully digital audio processing system, and stereo DSP multi-digital reverb for more professional vocal effects.
  • Microphone muting settings, independent compression design; adjustable frequency shift (2Hz–8Hz) for feedback suppression, with an optional "OFF" mode.
  • The effects channel is independently equipped with high/low-pass filters, and both reverb and echo feature a 5-band parametric equalizer (PEQ).
  • Each output channel includes a 7-band parametric equalizer (PEQ), high/low-pass adjustment, mix ratio, polarity, delay, compression, and gain functions.
  • Supports VOD infrared interface for device control.
  • Supports RS232 connection for computer-controlled operation, with professional PC device management software included.
  • Built-in RTA spectrum display to effectively identify feedback frequencies, eliminating howling completely.
  • Three-level engineering password lock function, allowing users to set device lock levels as needed.
  • Supports storage of 9 system presets, with the startup state set to the last saved configuration.
