<\/a><\/p>\nSo, some 70 years after its creation, the Baxandall EQ effectively gets a definitive update. Ultimately, Heritage Audio has successfully replaced the Baxandall shelving EQ topology to which it turned for inspiration with a functional equivalent \u2014 much more musical in its implementation as a single rack space-occupying master bus-\/mastering-orientated unit fit for vintage sound-seeking 21st Century studios: STEREO ASYMPTOTIC EQUALIZER, affectionately known as SYMPH EQ, takes its name from the shape obtained by its shelving curves (where the boosted or cut amplitude increases until the asymptotic value is reached, so sub lows and ultra highs are always controlled). After all, an asymptotic line is a line that gets closer and closer to a curve as the distance gets closer to infinity. In the case of the SYMPH EQ, its sound can only be described as tight, sweet, and natural, while its use of parallel equalisation to obtain the desired response curves results in exceptionally low phase deviation and also aids audio artefact reduction.<\/p>\n Since shelving with surgical yet musical precision is really what the SYMPH EQ is all about, a smart circuit layout allows for a maximum boost\/cut of 10.5 dB in 0.5 dB steps; the main rotary switch sets 1 dB steps whilst the +0.5 button adds half a dB to the main reading, while the CUT button turns the boost amount into cut. Six strategically-selected frequency choices per band are available \u2014 8, 10, 12, 15, 20, and 24 KHz on the high shelf, and 470, 360, 220, 110, 60, and 20 Hz on the low shelf.<\/p>\n Above and beyond that, there are also high-pass and low-pass filters available on dual concentric rotary switches at 12dB\/octave in order to keep the sub-low and ultra-high frequency content under control. Five frequency choices \u2014 10, 12, 18, 22, and 30 KHz on the low-pass, and 160, 82, 47, 20, and 15 Hz on the high-pass \u2014 plus OFF are available on each one.<\/p>\n Surely SYMPH EQ would already have been an awesome sculpting tool if it was only as just described above, but it turns into a monster masterpiece thanks to the following three additions: custom built by Carnhill, and manufactured for Heritage Audio by the renowned British company concerned in its Oxfordshire factory, its input transformers are the same as those found in Heritage Audio\u2019s acclaimed SUCCESSOR (STEREO BUS COMPRESSOR); its outputs are driven by 73-type Class-A output amplifiers, built with the same Carnhill output transformers \u2014 this time manufactured in St Ives, Cambridgeshire \u2014 as the rest of the European pro audio manufacturer\u2019s rack-mount products; and, most importantly, it boasts built-in M\/S (Mid-Side) capabilities, letting the SYMPH EQ really shine for all to hear. Having said that, nothing comes close to M\/S-equalising a mix since it allows the user to process the centre and sides separately with musically mind-blowing benefits \u2014 brightening mixes without making vocals sound harsh, or even tightening the stereo image\u2019s bass content without making bass or kicks sound weak, to name but a few examples of the SYMPH EQ\u2019s M\/S power! Put it this way: response of the Side high-pass filter has been made elliptical \u2014 just like vintage disk cutters \u2014 for precise frequency response.<\/p>\n Readily updating the Baxandall EQ, effectively, vintage sound-seeking 21st Century studio owners owe it to themselves to seriously consider adding a SYMPH EQ to their sculpting toolkit. This is where the musical magic lives! Like all analogue signal processing products produced by Heritage Audio, it is the sound of yesterday \u2014 built for tomorrow.<\/p>\n The SYMPH EQ is shipping and available via Heritage Audio\u2019s growing global network of dealers (https:\/\/heritageaudio.net\/where-to-buy-international\/) with an SSP (Standalone Selling Price) of \u20ac1,549.00 EUR (including VAT) in the EU and a MAP (Minimum Advertised Price) of $1,499.00 USD, US distribution being handled via RAD Distribution (http:\/\/www.raddist.com\/heritage-audio.php<\/a>).<\/p>\n<\/a><\/p>\n<\/a><\/p>\n
