Notes: Great value mid-range rotary mixer from Omnitronic, a big step up from the popular TRM-202. Large format two-channel design, featuring three-band channel EQs, master isolator, multi-mode filter and dedicated channel VU meters.

Supplier's Notes:
Rotary in its most beautiful form: Omnitronic TRM-222

With the TRM-222, Omnitronic presents an analogue rotary mixer that has been developed with direct feedback from the community.

Proven features have remained

Like its predecessors, the TRM-222 is equipped with a 3-band master frequency isolator, which uses classic ALPS rotary potentiometers (Blue Velvet RK27) for precise sound control. The kill characteristic allows bass, midrange and treble to be completely cancelled out, giving DJs creative freedom in shaping their sound.

The switchable filter section with HPF, BPF, LPF, resonance and sweep controls allows creative processing of the frequency bands. Two stereo input channels with gain control, clip LED, 3-band EQ and phono/line switching as well as a microphone input channel with gain control, 2-band EQ and on-air switch extend the mixer's range of applications. The LED level display for the master signal (L+R) and cue signal provide a good overview.

New functions at the request of users

During the further development of the mixer, great importance was attached to feedback from the community. New functions such as the VU meter display per channel, dipswitches for individual adjustment of the EQ curve and a booth output (XLR or RCA) with 2-band EQ and volume control testify to the sophisticated functionality of the TRM-222. At the request of the fans, the mixer now has a crossfader in VCA technology with adjustable crossfade characteristics, an adjustable send-return effect path and an adjustable record-out.

In addition, the TRM-222 offers two direct outputs for timecode applications and a variety of outputs: Master and Booth (XLR/ RCA L/R), Record (RCA L/R), Master Insert Send/Return (RCA L/R) and FX In/Out (stereo jack).

Notes: Mid-range model in the Resor two-channel series, the 2525 M features three-band EQ (as opposed to two-band on the standard 2525) and master isolator.

Supplier's Notes:
Resor 2525 M has a 3-band EQ per channel designed around their discrete class-A Op-Amp. The Bass control with a range of +/-18 dB at 100 Hz is great for sculpting the low-end frequencies, providing ample flexibility for enhancing or attenuating bass elements in the mix. The Mids control with a range of +/-12 dB at 800 Hz, and the Treble control with a range of +/-12 dB at 10 kHz enables adjustments to the high-frequency content, helping to add sparkle or tame any harshness.

Resor have encased the 2525M in a slim wooden chassis, which encompasses the faceplate, following the ethos of the four-channel models. Moreover, Resor have redesigned and improved the internal circuitry even further.

For a unique and personalised touch, among the extensive range of custom options, Resor offer Metallic Red, Metallic Blue, and Metallic Green faceplates; a Satin Dark wooden enclosure; as well as Urei, Matte Black, and Matte Silver Premium Aluminum Knobs.
