Critic Reviews

Mäag Audio EQ4M

soundonsound.com

The Maag Audio EQ4M offers impressive tonal shaping capabilities with its high headroom and distinct Air Band section, adding natural openness to mixes. Its user-friendly design and well-chosen frequency bands make it effective for mastering tasks. However, the notable overall level rise when boosting frequencies and higher mains hum in the right channel are drawbacks. Additionally, the lack of a physical user manual may frustrate some users. While it excels in enhancing audio quality, the EQ4M might not be the best fit for all applications, particularly for those seeking a true stereo control experience.

Mäag Audio: EQ4M 6-band stereo EQ | Tape Op Magazine | Longform candid interviews with music producers and audio engineers covering mixing, mastering, recording and music production.

tapeop.com

With its six-band design, the Maag Audio EQ4M excels as a mastering tool, boasting features like true in/out bypass and an invaluable 15 kHz Air Band® for precise vocal enhancement. The enhanced headroom from the ±18 V power supply is a notable upgrade, and the detented controls allow for quick adjustments. However, it's important to note that while the controls are not true stepped switches, the reviewer found no issues with channel matching. While not the cheapest option at $2395, the EQ4M stands as a quality choice for serious audio professionals looking to elevate their mixing and mastering processes.
