JB systems KM 4.1 karaoke mixer Product no.: W-01079 Warranty period: This product comes with a 3-year warranty.


This unit combines an echo device and a compact mixer in one small, 1U housing which can be installed in a 19-inch rack.

A special echo section lets you adjust various parameters for both microphone channels, so that you can always add a perfect echo to the signal!

Besides two microphone inputs, two line signals can also be added - for instance a mixer, laptop, karaoke player or whatever unit whose volume you need to control! The delay function of the echo is switchable between 0-400 ms and 400-800 ms.

A three-band equalizer can be used for both microphones to add a bit of colour.

This truly is an ideal system for stand-alone use or for use in larger installations.
