![]() ![]() ![]() ![]() 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. 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. This layout produces the best overall equalizer coherency. 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. It also utlilizes our BE44 discrete line driver at the output that acts like a transformer and can respond to balanced or unbalanced loads.īut 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 tansistor amplifier. audio path qualityĪs you would expect, the REQ uses our BE40 True Class A circuits developed for the MA-2.2 microphone amplifier for superlative audio performance. 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 inductor/capacitor resonant "tank" eq circuit runs at a low internal signal level which avoids any inductor saturation effects. The REQ-2.2 mastering equalizer utilises 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. ![]()
