    2x25 Watts @8 ohm or 2x35 Watts @4 ohm both in stereo
  • Bridge mode
    1x34 Watts @8 ohm or 1x56 Watts @4 ohm both in bridge mode
  • USB audio
    Provides audio playback and volume control on connected PC or Mac
  • 1 LAN port
    Enables control of the amplifier and adds two extra RS-232 ports for expansion of the control system
  • 2 Bi-directional RS-232 ports
    Used for control or expanding the AV system with more devices
  • 4 General Purpose I/O ports
    Used for extra input/output ports for control of relays, switches and sensors.
  • Auto power function
    Powers on when signal is detected, and enter sleep-mode automatically after 15 minutes without signal
  • Input 1 Mix function
    Possible to set Input 1 as an input, that mixes with the current selected input.
  • 3 band equalizer
    Works as an active filter for bass, mid and treble
