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.

Reviews

Brilliant EQ
This is a very musical EQ. You get a very sweet and tight low end and the highs are great as well, no harshness whatever, except there is a problem that needs to be fixed in the mix. The different frequency options you get from this unit makes it even unbeatable for that price point. This primarily lives on my mixbuss and I use it on my masters as well. Neve orbit to symph EQ to Neve MBP.
Great BAX EQ - But Better!
Well, the overall rating would have been 5 stars, however, i went through two units before the M/S button actually worked! Third time was the charm! This EQ is awesome! The fact that you can M/S process is why I got this one. Thanks to Rob Amaral the "Magic Man" He is truly the best!

Excellent!
This EQ is exactly what I've been waiting for! It's the perfect EQ for the stereo bus. Super clean. You can add a little sparkle or you can add a little low end. And the low end stays tight because of the curves of this eq. The high and low pass filter's are also super useful.
I would fully recommend!
Charmed
IT DOES WHAT IT IS SUPPOSED TO DO, IT'S CLEAN, MORE MUSICAL THAN THE BAX EQ. THE BASS IS HUGE. THE MID / SIDE IS PEREFECT. THE CONSTRUCTION IS OF HIGH QUALITY. IT'S A WAR TANK.
