70 years after it\u2019s creation, the Baxandall EQ gets a definitive update.
\nBaxandall equalizer\u2019s topology, introduced to the public by Peter Baxandall in 1952, was a very
\ningenious way of obtaining high and low shelves with boost and cut option without using expensive rotary
\nswitches. This affordable circuit was soon adopted by hi-fi and console manufacturers for its simplicity,
\nwhere parametric options aren\u2019t needed.
\nHeritage Audio has successfully replaced the Baxandall topology with a functional equivalent \u2014 a much
\nmore musical one, implemented as a one rack space, master bus\/ mastering type unit.
\nThe Stereo Asymptotic Equalizer, affectionately known as Symph EQ, takes its name from the shape
\nobtained by its shelf curves; where the boost or cut amplitude grows up until the asymptotic value is
\nreached, keeping the ultra highs and sub lows always controlled.
\nIts sound can only be described as tight, sweet, and natural, and its use of parallel equalizing to obtain
\nthe desired response curves makes it to have exceptional low phase deviation and artifacts.
\nShelving with surgical, but musical precision.
\nA smart circuit layout allows for a maximum boost\/cut of 10.5 dB in 0.5 dB steps. The main rotary switch
\nsets 1dB steps whilst the 0.5 button adds half a dB to the main reading. The CUT button turns the boost
\namount into cut. Six strategically selected frequency choices per band are available (8, 10, 12, 15, 20
\nand 24 Khz on the high shelf, and 470, 360, 220, 110, 60 and 20 Hz on the low shelf).
\n2 pole high and low pass filters.
\nIn order to keep the sub-low and ultra-high frequency content well under control, further high-pass and
\nlow-pass filters have been added on dual concentric rotary switches, at 12dB\/octave. 5 frequency
\nchoices plus OFF are available on each one (10, 12, 18, 22 and 30 Khz on the low-pass, and 160, 82,
\n47, 20 and 15 Hz on the high-pass).
\nThis is where the magic lives.
\nThe Symph EQ would have been an awesome sculpting tool just as it has been described above, but it
\nturns into a monster piece with the following 3 additions:
\n\u00b7 It features the same exclusive Carnhill input transformers made in Oxford found in the
\nSuccessor.
\n\u00b7 Its outputs are driven by 73-type Class-A output amplifiers, built with the same Carnhill St \u0301Ives
\noutput transformers as the rest of the family.
\n\u00b7 Most importantly and, here is where the Symph EQ really shines, it has built in Mid Side (M\/S)
\ncapabilities.
\nM\/S Equalizing cannot be rivaled.
\nNothing comes close to M\/S equalizing a mix. It allows the user to process the center and the sides
\nindependently. The benefits of such processing are hard to believe. You can brighten your mix without
\nmaking your vocals sound harsh, or even tighten the stereo-image\u2019s bass content without making your
\nbass or kick sound weak! This are just a few examples of the Symph EQ M\/S power!
\nThe response of the Side high pass filter has been made elliptical as in the vintage disk cutters for
\nprecise frequency response.
\nBULLET POINTS:
\n\u00b7 Custom Carnhill Oxford input transformers, and custom Carnhill St Ives output transformers,
\nboth exclusively made for Heritage Audio.
\n\u00b7 A high-end, 73-style Class-A output stage.
\n\u00b7 All controls use high-quality rotary switches for 0.5dB precision equalizing.
\n\u00b7 Mid-side processing allows for precise center bass management and high boosting hard
\npanned sources without affecting center ones such as vocals, snare, etc. Side high-pass filter
\nturns into elliptical type when in M\/S, as implemented in vintage disk cutters.
\n\u00b7 Stereo and M\/S inputs and outputs, all balanced and ground free (unbalanced compatible)
\non gold plated XLRs.ON, M\/S or stereo mode and individual hard BYPASS per channel.
