MR216 Eco-System Trigger


The Knoll Systems MR216 Eco-System™ Trigger allows amplifiers, subwoofers and other products to be activated or powered on when an audio signal is present. When the audio signal is lost the activation is stopped.


The most important feature of the Eco-System™ circuit in the MR216 is the energy or electrical savings that is delivered to the owner over a period of time. The typical home owner will see a savings of hundreds of dollars or more per year in actual electrical costs and that can be multiplied when taking into account the increased costs of air conditioning the home to extract unwanted heat produced by a products powered up and not in use.
