The 2-channel version of this mixer, the TRM-202 MK3 from Omnitronic, was particularly popular with DJs of electronic music all over the world. With the TRM-402 4-channel rotary mixer, the popular concept is extended by 2 channels: Now nothing hinders a creative 4-deck DJ set or a flying change during a gig. Of course, this version also incorporates the classic features of a rotary mixer in the form of ALPS rotary controls (Blue Velvet RK27) and a 3-band frequency isolator. The high-quality components of the TRM-402 ensure an appealing sound image. The large rotary knobs of the 4 channels allow the DJ to create very smooth transitions, which are so difficult to set with a conventional mixer (with faders). All channels can be switched between line & phono inputs or sources. A microphone input is also available. The kill characteristic of the isolator ensures the complete elimination of bass, midrange and treble and thus creative mixing. The TRM-402 is equipped with a booth output and a separate volume control. So the use of the mixer in the club is no problem at all. Thanks to the record out, it is also possible to record your own DJ set.
