Outstanding “Invisible” Mic Preamps

The EURORACK UB2222FX-PRO features our ultra-low noise, high-headroom IMP “Invisible” mic preamps, which have been praised by audio professionals all over the world. These studio-grade mic preamps off er a staggering 130 dB of dynamic range, with a bandwidth that extends from below 10 Hz to over 200 kHz, and are perfectly matched to every conceivable microphone – with up to 60 dB gain and a +48 V phantom power supply. Armed with these outstanding mic preamps, the EURORACK UB2222FX-PRO provides exceptionally-transparent and crystal-clear sonic performance – making them ideal for both live sound and studio recording applications.

Effective and Highly-Musical Channel EQs

All of the UB2222FX-PRO’s mono channels have a 3-band EQ – with semi-parametric mid bands for the ultimate in tone shaping. Both the High and Low bands provide a ±15 dB boost or cut to all frequencies above or below their cut-off frequencies, which are fixed at 12 kHz and 80 Hz respectively. For the midrange, the UB2222FX-PRO features a semi-parametric equalizer with a Q (filter quality) of 1 octave, which is tunable from 100 Hz - 8 kHz. Use the Mid control to set the amount of boost or cut, and the Frequency control to set the center point.

A stereo EQ is superior to two mono EQs for stereo signals, because two separate EQs can often create an imbalance between the left and right channels. The stereo channels in the UB2222FX-PRO contain a stereo EQ with cut-off frequencies of the High (12 kHz) and Low (80 Hz) bands, while the center frequencies of the High-Mid and Low-Mid bands are 3 kHz and 500 Hz respectively. Stereo channel High and Low controls are identical in their characteristics and functionality as those in the mono channels.

Effective FX

Every UB2222FX-PRO features our 24-Bit Multi-FX processor, with 100 awesome presets including reverb, chorus, flanger, delay, pitch shifter and various multi-effects. Complete with a highly-accurate input meter, these effects are instantly available at your fingertips via the Program selector control.
