1A Equalizer
A modern take on the classic Pultec tube EQ. 1A Equalizer blends the silky-smooth curves of vintage hardware with flexible digital control. Whether you're adding air, tightening the low end, or enhancing presence, it delivers bold tone without harshness.

Boost and attenuate
Boosting and attenuating lows or highs is a defining feature of classic Pultec-style EQs, and Audified nails the signature curve. Recreate the legendary “boost-and-attenuate” trick for rich, musical tone shaping that stands out.

Precise saturation
Dial in the perfect amount of analog-style saturation with a dedicated calibration knob. Great for finding that sweet spot between subtle warmth and bold color.

Visualize distortion
See how much harmonic saturation you're adding with a built-in Total Harmonic Distortion display.

Mid-side processing
Shape the width and balance of your mix with Mid/Side processing. Control the center and sides separately to open up space, fix stereo issues, or add polish to your master. Link parameters or toggle between L/R and M/S modes for flexible stereo shaping.
