Heritage Audio has announced availability of its master bus stereo asymptotic equalizer Symph EQ.

The one rack space, master bus/mastering type unit replaces the Baxandall topology with a functional, much more musical equivalent.

The Stereo Asymptotic Equalizer, affectionately known as Symph EQ, takes its name from the shape obtained by its shelf curves; where the boost or cut amplitude grows up until the asymptotic value is reached, keeping the ultra highs and sub lows always controlled.

Its sound can only be described as tight, sweet, and natural, and its use of parallel equalizing to obtain the desired response curves makes it to have exceptional low phase deviation and artifacts.

Symph EQ features

  • Custom Carnhill Oxford input transformers, and custom Carnhill St Ives output transformers, both exclusively made for Heritage Audio.
  • A high-end, 73-style Class-A output stage.
  • All controls use high-quality rotary switches for 0.5dB precision equalizing.
  • Mid-side processing allows for precise center bass management and high boosting hard panned sources without affecting center ones such as vocals, snare, etc. Side high-pass filter turns into elliptical type when in M/S, as implemented in vintage disk cutters.
  • Stereo and M/S inputs and outputs, all balanced and ground free (unbalanced compatible) on gold plated XLRs.ON, M/S or stereo mode and individual hard BYPASS per channel.
  • Fully manufactured in the EU.

The Symph EQ is shipping and available via Heritage Audio’s growing global network of dealers with an SSP of 1,549.00 EUR (including VAT) in the EU and a MAP of $1,499.00 USD.
