The EQ4M is a no-compromise dual-channel, 6-band unit that works differently than other EQs you've likely used, with ultra-wide-range control from the subsonic to the acclaimed AIR band.
Due to its unique design, phase shift is kept to a minimum in the Maag Audio EQ4M. This lets you preserve the integrity of your material and enhance the airiness of the recording, while shaping the tonality from top to bottom. The Air Band, in conjunction with the absence of phase shift, makes the EQ4M perfect for any signal that needs shaping.
The bandpasses in the EQ4M interact with one another. If you increase the Air Band gain, you'll also, to a small degree, increase your overall gain. This ensures the integrity of the sound and is an intended consequence of the design stemming from the summing (interaction) of the Air Band with the other bandpasses. To compensate for any additional gain, simply back down the Input Attn knob and your EQ will maintain its shape.
Looked at another way, if you're boosting a particular frequency, consider backing down level on neighbouring bandpasses above and/or below. Because the bandpasses interact with one another, this behaviour is quite a bit different than your typical EQ. Once you get used to how the bandpasses and the Air Band interact in the EQ4M, you'll be able to quickly shape your sound and achieve stunning high-end presence and transparency, all the while remaining faithful to the true sonic nature of your source.
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 power, means more headroom. The EQ4M has an extra 2v compared to the EQ4 and boosts headroom to +29 dBu.
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).
