  • Compact design built from an extruded aluminum heatsink with the top side
  • ensuring effective transfer of the heat generated by the power electronic components.
  • Selectable ART, Automatic Remote Turn-On/Off function, automatically turns on and off the amplifier when the OEM radio turns on and off (available on Speaker-In only).
  • Power supply stage featuring multiple winding transformer, Low-ESR 105°C capacitors, D-Class 2 Ω stable.
  • Pre-out, also available when using Speaker level inputs, with continuously adjustable (50 to 250 Hz) Hi-Pass filter. Allows to create a Band-Pass filter with the front woofer amplifier to eliminate sub frequencies.
  • Selectable full range power output, for dual-mono powerful audio systems. Bass Boost (50 Hz) adjustable to 12 dB, to increase the subwoofer punch. 24 dB continuously adjustable (50 to 250 Hz) Lo-Pass filter.
  • SUBSONIC filter (24 dB – 25 Hz), removes very low subsonic frequencies from music signal to avoid damages to the subwoofer.
  • Continuously adjustable PHASE control (0 to 180°); it increases bass alignment of woofer with sub.
  • Optional Remote Volume Control (HRC); allows the user to adjust subwoofer level from dashboard.
  • Special balanced input circuitry to reject electro-magnetic disturbances present on the Pre-In or Speaker-In inputs.
  • Input featuring both Speaker-In (OEM radio) and RCA-In (Aftermarket radio) inputs.
