Key Features

  • Input Multiplexer: Supports quasi-differential stereo inputs (QD1), single-ended stereo inputs (SE1, SE2, SE3), and full-differential or quasi-differential stereo input (FD/QD2).
  • Loudness Control: Programmable center frequency (400 Hz / 800 Hz / 2400 Hz), 15 dB with 1 dB steps, and selectable high frequency boost or flat-mode.
  • Volume Control: +23 dB to -31 dB with 1 dB step resolution, soft-step control with programmable blend times.
  • Bass, Middle, and Treble Adjustments: 2nd order frequency responses with programmable center frequencies and Q factors for each band.
  • Speaker and Subwoofer Controls: Independent soft-step controls for speakers and subwoofer, with programmable cut-off frequencies for the subwoofer.
  • Mute Functions: Direct mute and digitally controlled soft-mute with programmable mute times.
  • Offset Detection: Offset voltage detection circuit for on-board power amplifier failure diagnosis.
