Power switch on Audio signal

I am looking for a kit (assembled component) with the following feature(s):

  1. Switch on 230V (power connection) on audio signal
  2. Switch off 230V after 5min if no audio signal

audio signal feed preferably by cinch (stereo)

thanks a lot

Sorry, no such product in our range.
Our subwoofer K8077 and power block amp K8081 feature auto turn-on with music sense.
