Key Features

  • Wide-range supply voltage.
  • 5 V to 26 V (operating range).
  • 30 V (absolute maximum rating).
  • Four power output configurations.
  • 2 channels of ternary PWM (stereo mode) (2 x 50 W into 6 Ω at 25 V).
  • 3 channels - left, right using binary and LFE using ternary PWM (2.1 mode) (2 x 18 W + 1 x 40 W into 2 x 4 Ω, 1 x 8 Ω at 25 V).
  • 2 channels of ternary PWM (2 x 50 W) + stereo lineout ternary.
  • 1 channel of ternary PWM as mono-BTL (1 x 9.
