The Maag Audio EQ4M™ is a 6-Band Dual Channel Mastering EQ with AIR BAND® (shelf boost from 2.5 to 40kHz), a true in/out bypass, a transparent INPUT ATTN (attenuator), and stepped (detent) controls.

In 1993, Cliff Maag first introduced the AIR BAND® to the audio world in the NTI EQ3. The EQ3 was a dual channel 6-band EQ powered in a 19 inch rack and to this day is hailed as one of the most musical equalizers ever made. Over two decades later, Maag Audio has captured the spirit of the EQ3 in the EQ4M™ by providing More Power, More Headroom, and More Control than ever before.

More Power
The EQ4M™ rides on extremely clean +-18v rails without the need of any supporting chassis or power source. Just plug it in and make music.

More Headroom
More power, means more headroom. The EQ4M™ has an extra 2v compared to the EQ4® and boosts headroom to +29 dBu.

More Control
The EQ4M™ offers more control with its true in/out bypass, a transparent INPUT ATTN (attenuator), and an extra 15 kHz selection on the AIR BAND®. All controls are stepped (detented).


The EQ4M is the stereo mastering version of the famed EQ4-500, with improved headroom (29dB!) as well as dented pots throughout.
Few modern circuits have made the rounds as successfully as Cliff Maag’s AIR BAND. It  has become a true industry standard in not time, to be found in just about every larger studio I’ve been to in the last years.
Not surprisingly engineers all over the world found that the AIR BAND works as well on mix bus as it does on lead vocals and various other sources.
Thus the EQ4M, and yes, it makes all the sense in the world to boost 40k on a mix bus, feels a bit like pulling a curtain aside.
Never underestimate the five remaining bands though.
They are particularly well chosen for mix bus applications and will help you to make a mix sound bigger and simply much more like “a finished record” real fast.
Great tool this.
