Digital echo chamber

Velleman MK182: Digital Echo Chamber Kit

Velleman MK182

Have you ever wanted to give your voice an echo like the rock stars do? Now you can with the MK182. The echo chamber has four controls for the MIC or input level, volume or output level, echo time delay (80 to 200ms) and feedback. Because of the 40Kb SRAM, the MK182 has low distortion and good sound quality. With the on-board microphone and audio amplifier (500mW at 8ohms), you can get started right away. A line in and line out connection is included, too. You can run the MK182 on a nine volt battery or a 9 – 12 volt regulated power supply (both sold separately). This unit only requires 180mA to run. The small footprint 3.35” x 2.76” x 0.78” still provides for a lot of fun.



  • Power supply: 9V battery (6LR61 not incl.) or 9...12V DC regulated
  • Power consumption: 150mA max.
  • Delay time: 80…200ms
  • Speaker output: 500mW (8 ohm, 10% THD)
  • Dimensions: 3.35 x 2.76 x 0.78"
