The Buzz Audio REQ-2.2ME Equalizer offers all the same features as the REQ-2.2, but with the addition of an Choke Low Band Filter.
The Buzz Audio REQ-2.2ME Equalizer utilizes parallel resonant circuits in a clever configuration whereby the bandwidth (Q) of the circuit can be adjusted like an active filter, but without any complex relay switching. The inductor/capacitor resonant tank eq circuit runs at a low internal signal level which avoids any inductor saturation effects. The overall result is the sound of real choke based filters with a big open sound, but without the limitation of only a few - or no bandwidth selections as found on traditional choke eq's. The REQ-2.2ME uses a Choke Filter on the Low Bands, which is a passive filter that filters out high-frequencies, utilizing inductors (among other components). As we all know, inductor based EQ's and Filters offer a smooth and musical tone. This passive choke filter will provide proper focus on low frequencies, providing a soncially rich bottom end sound.

Audio Path Quality
As you would expect, the REQ uses our BE40 True Class A circuits developed for the MA-2.2 microphone amplifier for superlative audio performance. It also utlilizes our BE44 discrete line driver at the output that acts like a transformer and can respond to balanced or unbalanced loads. But sometimes you might need a bit more color, so we have included a saturation section that introduces measured amounts of low frequency harmonic distortion via a steel audio transformer driven by a single ended transistor amplifier. The High Pass Filter is placed in the beginning of the eq chain and the Low Band eq section is placed last in the chain. This layout produces the best overall equalizer coherency.
Operational Beauty
The large knobs and positive feel of the switching make the REQ a pleasure to operate and everything is visually clear when mounted into a console. In total there are 72 frequency choices per channel with overlapping selections across the four bands so you can always find the centre frequency you are looking for. A looping line XLR input and two parallel XLR outputs provide flexible connection options in the mastering control room. Finally, low glare rustic silver finish and retro Elma knobs give the REQ an impressive look in your rack!
