Omnitronic TRM-402 Rotary Mixer - Back to the Roots!
Especially popular among electronic music DJs worldwide was the 2-channel version of this mixer, the TRM-202 MK3 from Omnitronic. The TRM-402 4-Channel Rotary Mixer expands this beloved concept by 2 channels: now nothing stands in the way of a creative 4-deck DJ setup or seamless transitions during a gig. Naturally, this version also features the classic rotary mixer elements with ALPS rotary knobs (Blue Velvet RK27) and a 3-band frequency isolator.

Smooth Transitions
The high-quality components of the TRM-402 ensure an appealing sound image. The large rotary knobs on the 4 channels allow the DJ to create very smooth transitions, which are difficult to achieve with a conventional mixer (with faders). Each channel can switch between line and phono inputs or sources. A microphone input is also available. The kill characteristic of the isolator allows complete cancellation of bass, mids, and highs for creative mixing.

Record Your Own Set
The TRM-402 is equipped with a booth output and a separate volume control. This makes using the mixer in a club hassle-free. Thanks to the record output, it is also possible to record your own DJ set.
Retro Fun with 4 Channels!
