Featuring 3 bands of EQ inspired by Mr. Neve’s most prized vintage designs, along with custom-wound inductors, transformers and class-A gain blocks, the 551 brings the thick, powerful lows and sweet highs of Rupert’s classics to the 500-Series format for the very first time.\u003c\/p\u003e\n\u003ch4\u003eThe “Best-Of” EQ\u003c\/h4\u003e\n\u003cp\u003eThe 551’s 3-band, custom-tapped inductor EQ was inspired by our favorite elements of Rupert’s vintage EQ designs. The low frequency band is designed to produce a creamy, resonant bass response similar to a vintage 1064 – but unlike the vintage modules, the LF band on the 551 can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end.\u003c\/p\u003e\n\u003cp\u003eThe midrange band is based on that of the 1073, ideal for sweetening vocals and instruments while bringing them forward in a mix, and its proportional “Q” response makes it well-suited for minimizing problematic frequencies. The high frequency band is a hybrid vintage \/ modern design, blending inductor circuitry with capacitor-based topologies to achieve vintage tones with enhanced control. The High Pass filter is a 12dB\/octave design with a fixed 80Hz frequency, and can be used in tandem with the low frequency EQ to add low-end presence without clouding the source material.\u003c\/p\u003e\n\u003cp\u003eAs with Rupert’s most prized classic designs, each EQ section uses low-feedback, class-A discrete electronics to prevent low-level artifacts and harshness from detracting from the tonal shaping. However, this new circuit is a decidedly modern design with updated techniques and components that were simply not available 50 years ago, and is definitely not a “clone”.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEQUALIZER BYPASSED\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOISE\u003cbr\u003e\u003c\/strong\u003e\u003cem\u003eMeasured at Main Output, un-weighted, 22Hz-22kHz, source impedance 40 Ohm balanced.
