The 2-channel version of this mixer, the TRM-202 MK3 from Omnitronic, has gained worldwide popularity, especially among DJs in electronic music. The TRM-402 4-channel rotary mixer expands this popular concept by adding 2 channels: now, nothing stands in the way of a creative 4-deck DJ set or seamless transitions during a gig. Of course, this version also incorporates the classic features of a rotary mixer, featuring ALPS rotary knobs (Blue Velvet RK27) and a 3-band frequency isolator.

The high-quality components of the TRM-402 ensure an appealing sound profile. The large rotary knobs for the 4 channels allow the DJ to create very smooth transitions, which are difficult to achieve with a conventional mixer (with faders). All channels can switch between line and phono inputs or sources. There is also a microphone input available. The kill characteristics of the isolator allow for the complete elimination of bass, mids, and highs, enabling creative mixing.

The TRM-402 is equipped with a booth output and a separate volume control, making its use in clubs hassle-free. Additionally, the record output allows for the possibility of recording your own DJ set.
