Description
  • Standard chassis design, 2U aluminum alloy panel, integrated handle and ear mount design, suitable for cabinet or desktop installation
  • Professional noise gate controls output signal to suppress background music
  • One MP3 master volume knob for unified MP3 volume control, two-band parametric EQ knobs for adjusting bass and treble to enhance sound quality
  • Independent volume knobs for each line input and each microphone channel
  • Ding-dong prelude button automatically plays the prompt tone at maximum volume, with customizable one-touch alarm music
  • MP3 player capable of playing audio from USB flash drives and SD cards up to 32GB, Bluetooth functionality included
  • FM radio capable of receiving radio stations from 88-108MHz
  • 5 audio inputs, including 3 standard line inputs and 2 standard microphone inputs
  • One-channel audio output, loopable to the next amplifier's audio input
  • MIC1 has the highest priority and automatically mutes when a signal is input. Junction FETs perform priority conversion to ensure signal distortion during muting
  • Six-channel volume control, five adjustable levels per zone
  • 70V and 100V constant-voltage outputs, 4-16Ω constant-resistance outputs, six-channel constant-voltage outputs from CH1 to CH6
  • Real-time operating status indicators: three signal indicators, one protection indicator, one distortion indicator, and one power indicator
  • Line safe operating range protection ensures safe operation of the output load in harsh environments, including short circuits and overloads
  • Comprehensive thermal protection: When the unit temperature rises, the temperature servo circuit accelerates the fan, ensuring low fan noise
  • Peak negative feedback protection: When signal distortion, surges, or severe line voltage overvoltage occurs, the fan is automatically turned on. This effectively protects the amplifier
  • Integrated crossover compensation circuitry corrects high-frequency losses caused by line transformers, resulting in a flat signal spectrum and beautiful sound quality on the line voltage
  • High-octave bass cut circuitry utilizes low-cut technology with tone compensation to remove potentially hazardous ultra-low frequency components without sacrificing sound quality, ensuring safe operation of the boost system
