Heritage Audio is offering a high-class take on the Baxandall curve with their SYMPH EQ, a stereo equalizer for professional engineers. A Baxandall curve, with its special, extended low- and high-end shape, offers a smooth and hi-fi way for high-end polish, low-end fullness, and overall mix control. This EQ gives you classic Baxandall behavior and more
The Definitive Baxandall Update
Place the Heritage Audio Symph EQ on your master bus, and you'll infuse your mixes with sweet-sounding highs and tight, natural lows. This stereo asymptotic shelving equalizer offers an exciting update to classic Baxandall-style units, with 0.5dB-precision rotary controls and M-S processing for hyper-accurate tone shaping that's guaranteed to elevate your projects. The Symph EQ exhibits a super-transparent sound with near-zero phase deviations and other sonic artifacts, and it's as simple to use as the bass and treble controls on an old-school stereo system. The Symph EQ boasts top-shelf Carnhill transformers, 73-type Class A output stages, and gold-plated XLR jacks.

Stereo asymptotic equalization explained
The Symph EQ is a stereo asymptotic equalizer, in which the boost or cut amplitude of its shelf curves increases until the asymptotic value is reached. These curves ensure that the unit's ultra-high frequencies and sub-low frequencies remain well controlled. The end result sounds tight, sweet, and natural, with exceptionally low phase deviation. It's this level of sonic transparency that makes the Symph EQ ideal for mastering duties.
M-S processing permits an unprecedented level of accuracy
At Sweetwater, we're impressed by the Heritage Audio Symph EQ's level of accuracy. All of its controls utilize high-quality, 0.5dB-precision rotary switches. Onboard M-S processing permits dead-accurate center bass management, as well as high boosting hard-panned sources without affecting center ones. What's more, when in M-S mode, the unit's side highpass filter is similar to the elliptical-type filters employed by vintage disk cutters.


High-quality components achieve hi-fidelity sound
The Symph EQ was built with top-shelf components. Carnhill input and output transformers ensure a robust, high-fidelity sound, while 73-type Class A output stages further minimize unwanted distortion. You also get balanced, ground-free I/O and gold-plated XLR jacks to ensure rock-solid connections.
