Product Features

Front Panel

  • Volume: These buttons increase and decrease the signal output of the amplifier.
  • A/B: This button toggles between the A and B hardwired inputs on the back panel or the individual front panel inputs. Use of the front panel inputs will override those on the back panel.
  • IR Sensor: The WA40W-AMP is capable of receiving IR (Infrared) light signals from the Nuvo wireless remote control. This enables the power, volume and A/B source selection to be done wirelessly.
  • Audio Inputs: Two stereo inputs are available for front panel use with any device that provides a stereo line level signal.
  • Power: This button turns the amplifier on and off as a toggle function.

Back Panel

  • DC Input: This 16V DC, 2.81A input connects to the included power supply. Once connected, the power supply can plug into any AC power source.
  • Speaker Output: The speaker output section terminates with standard audio wire. This provides the amplified audio signal to the attached speakers. The NV-WA40W-AMP is designed for a pair of 4-ohm speakers or a single stereo speaker rated at 4-ohms per channel.
  • Audio Inputs A and B: These inputs allow up to two line level sources to be permanently hardwired into the back panel. Selection for source playback is made through from the front panel A/B button or the wireless remote control. The inputs are automatically overridden when one of the front panel audio inputs is used.
