Buzz Audio REQ 2.two Mastering EQ MP Palazzo
REQ-2.two MP mastering version with +/- 8dB boost/cut by means of 23 position PALAZZO brand switches.
The REQ is actually a mixture of passive filter circuits and active amplifier stages. Parallel resonant chokes and capacitors type the frequency selective portion of each and every band and these are coupled in to the amplifier stage through the boost/cut management. The resulting equalisation is ideal described as “surreal” and it never ever sounds challenging or harsh. The low frequencies stay tight and powerful using the high frequencies clear and properly defined.
A lot of other equalizers using passive filters have restricted centre frequency alternatives, but the REQ boasts 72 different frequencies split above 4 bands per channel. The substantial and low bands might be switched to bell or shelving mode and the two bell mid bands have two centre frequency ranges. Every band includes a bandwidth (Q) manage and in the event the substantial or reduced bands are switched shelf mode, this control reverts to a shelf “slope” handle. Also a passive large pass filter and a variable “saturation” module are offered. The saturation module converts the REQ into a much more “vintage” sounding unit by adding harmonics for the signal via the use of a steel audio transformer driven by a “single ended” old style Class An amplifier (see distortion specs below). The low frequency response can also be altered by the saturation control, depending on the position of this switch.
The difference in between the Palazzo switches and Elma switches could be the Palazzo are lower expense but have a heavier “feel” in comparison with the Elma. Normally the Elma version is built to order.
All other controls on all versions are switched for repeatability. The substantial pass filter from the mastering version provides smaller steps and varying filter slopes to that around the recording version.
Taking a search within the REQ chassis you’ll learn a vey high level of engineering and develop quality with modular construction for simple serviceability, high quality controls, single point power supply wiring, discrete energy regulators for each band – the checklist goes on and on.
