OMNITRONIC DJ TRM-422M - 4-Channel Rotary Mixer

The Best of the TRM Series, Designed With and For DJs

Omnitronic expands its iconic "TRM" series with the TRM-422, a refined version that retains the aesthetic and character of rotary mixers while incorporating community feedback. The vintage-style 3-band isolator and ALPS potentiometers confirm its audiophile positioning, while the connectivity and modern options place it at the top of the range.

Who Is It For and What Are Its Uses?

The TRM-422 is aimed at house, techno, disco, and open-format DJs seeking the fluidity of a 4-channel rotary mixer in clubs, bars, private events, or fixed installations. Sound engineers and selectors will appreciate its dedicated booth with EQ, dual headphone outputs, and FX send/return for external processors. In the studio, its musical character and direct timecode outputs facilitate DVS integration (Serato, Traktor).

Features and Innovations

Each channel offers two line inputs, one switchable to phono, gain control, 3-band EQ, and access to a full filter section (HPF/BPF/LPF) with resonance and sweep control. The 3-band master isolator allows spectacular cuts while preserving musicality. The monitoring section is refined with an booth output on XLR/RCA, 2-band EQ, and an advanced PFL (mix/split, 16-segment VU meters). Creatives benefit from two FX send/return plus a master insert for chaining effects. A fully assignable and defeatable VCA crossfader complements the traditional rotary approach. The front AUX input (3.5 mm mini-jack) serves as a backup source, while the RCA "Record Out" output simplifies set recording.
