3-channel sound light with microphone

Velleman K8017: Three Channel Sound Light with Microphone Kit

Velleman K8017

Velleman K8017 3-Channel Sound Light with Microphone Kit (Electronic Project Kit -Soldering Required)

The Velleman K8017 Three Channel Sound Light with Microphone kit works with incandescent light bulbs to create sound to light effects. The on-board microphone picks up sounds and the circuit splits them into three channels (low, mid and high). Each light flashes to its respective channel. Use the master level control to adjust the sensitivity of all channels or use the individual adjustments to get just the right effect.


The DIY kit is supplied with a transparent enclosure and colored knobs for the channel adjustments. The circuit also includes LED indication for each channel and a power LED. This kit operates from mains voltage, which can be dangerous. Use caution and always close and fasten the enclosure when using this kit (mains power cord is not included).



  • Operating voltages: 110-125 or 220-240V AC (50/60Hz)
  • Max. load: 200W per channel (100W @ 110-125V AC)
  • Only suited for incandescent light bulbs
  • Dimensions: 6.1 x 1.8 x 6.3"
