OMNITRONIC ISO-23 MK2 DJ Isolator

OMNITRONIC ISO-23 MK2 – 3-Band DJ Isolator in 19" Format for Professional Sound Control

The OMNITRONIC ISO-23 MK2 is a high-quality 3-band frequency isolator in a practical 19"-rack format that offers DJs an effective way to shape and manipulate sound during live performances. With its precise boost and kill functions across three separate frequency bands, the ISO-23 MK2 enables dynamic, creative mixing techniques—from smooth transitions to radical filter effects.

Ideal for clubs, professional DJ booths, or studio installations, the ISO-23 MK2 not only provides outstanding control over the sound but also impresses with its build quality, classic ALPS potentiometers, and flexible connectivity options.

Professional sound shaping with Boost & Kill

The OMNITRONIC ISO-23 MK2 allows you to split the incoming stereo audio signal into three frequency bands—bass (20 Hz – 300 Hz), mids (300 Hz – 4 kHz), and treble (4 kHz – 20 kHz). Each band can be completely isolated (“kill”) or boosted by up to +9 dB. This feature enables extremely precise adjustments to the sound—ideal for breakdowns, builds, and transitions in a DJ set.

Thanks to Butterworth filters with 18 dB/octave, the ISO-23 MK2 separates the frequency ranges cleanly and musically. The crossover frequencies between Low/Mid and Mid/High were chosen with practical application in mind and ensure balanced, intuitive tone control.

Top-of-the-line hardware with ALPS potentiometers

Control is handled via classic ALPS Blue Velvet RK27 potentiometers, which have been the industry standard for high-quality audio applications for decades. They not only offer an excellent feel but also reliable, precise control without dropouts or unwanted level jumps—a crucial quality feature for live performances.

A bypass switch allows you to switch directly to the unprocessed signal, so the effect can be turned on and off live—handy for spontaneous mix changes or A/B comparisons during a performance.

Flexible connections for any setup

The OMNITRONIC ISO-23 MK2 is equipped with balanced XLR and unbalanced RCA connectors, for both inputs and outputs. This allows it to be easily integrated into analog DJ mixers, PA systems, or studio setups—regardless of whether you’re working with balanced or unbalanced signals.

With a maximum input level of +22 dBu, the isolator is also suitable for professional signal levels and can be combined with standard DJ mixers or audio interfaces without any level issues.

Rugged 19" enclosure for rack mounting

The ISO-23 MK2 comes in a 19"-format (1U) and is therefore ideal for permanent integration into DJ racks, flight cases, or studio installations. The included mounting brackets make installation particularly easy. With compact dimensions of 48.3 cm x 14.5 cm x 4.5 cm and a weight of 2.15 kg, the isolator remains easy to handle even when on the go.

Why the OMNITRONIC ISO-23 MK2 Is the Perfect Choice for DJs

The OMNITRONIC ISO-23 MK2 is a well-designed, high-quality tool for DJs who want more control over their sound. Combining professional filter technology, high-quality components, and flexible connectivity options, this isolator is a valuable addition to any DJ setup—whether in a club, in the studio, or on the go.

Its intuitive control scheme makes it easy for beginners to use, while also offering experienced DJs the ability to creatively shape and manipulate their sound. Whether for classic filter sweeps, frequency cuts, or as a tonal design element—the ISO-23 MK2 delivers reliably, precisely, and musically.
