The RDM20 is an analog two channel rotary DJ mixer, with one phono and two line inputs on each channel.  Two different three band isolator-banks were developed and built into the RDM20. One is set on the master and there's another one on each channel. While the master isolator is quite steep and raw, the character of the channel isolator is more soft and smooth.

There are two balanced outputs (House XLR, Booth Jack), as well as a separate steady recording output (cinch). The linear power supply unit is built in, no extra mains adapter needed. Analog VU-meters are indicating the level of the master.

Using only the best electronic components built into a solid metal housing, this device is made to stand the test of time – even in the rough conditions of the dusty and sweaty club environment."
