Essential Info

Xantech has designed a network to control your A/V system using inputs from various sensors - power on/off, video or audio signal sensing, etc. This Audio Sensor Module installs between an audio source (iPod, CD or DVD player, tuner, etc.) and an amplifier. When it senses that audio signals are present, it sends a signal to the controller. Power is supplied by the Current Sensor Connecting Block.

    Part of a Versatile Control System
    This Audio Sensor is only one of a wide range of sensors to send signals to your programmable controller. Here's the complete list:

  • Current Sensor Connecting Block and Current Sensing Module - work together to sense whether your "master" component's power is on or off
  • Audio Sensor Module - senses audio signals from a CD or MP3 player, etc
  • Video Sensor Module - senses video signals from a satellite receiver, DVD player, etc
  • Audio Sensor Module - trigger events with audio signals from your iPod dock or AM-FM tuner
  • Magnetic Sensor Module - uses the magnetic field surrounding AC wiring, CRT monitors, or AC motors
  • LED & Light - signals when it detects light
  • Contact Closure - triggers upon contact closure

    Simple Installation
    Plug into either left or right line-in on an amplifier, then connect to your Current Sensor Connecting Block. Adjust the sensitivity & time delay controls and you're finished.

    Note: use for line-level signals only. Do not use with amplifier outputs or speaker volume controls.

    This device is brilliant! Delay only applies to the off so you can get instant component detection from the on while still having a nice long delay to prevent false offs from pauses and transitions in music.
