Mäag Audio EQ4M dual-channel mastering EQ, purchased new in 2024 and in excellent condition, complete with original box and accessories.

A mastering-grade stereo equalizer with the classic Mäag sound, the EQ4M gives you six bands per channel, including the famous Air Band® for adding top-end openness without harshness. Each channel includes fixed bell bands at 10 Hz, 40 Hz, 160 Hz, and 650 Hz, plus a 2.5 kHz shelf and selectable Air Band frequencies at 2.5, 5, 10, 15, 20, and 40 kHz. All controls are stepped for precise recall, with true bypass, input attenuation, and plenty of clean headroom thanks to the internal ±18 V±18 V supply and up to +29 dBu headroom.

A great option for mastering or mix-bus duties if you want musical tone shaping, fast repeatability, and that signature airy top end the Mäag units are known for.
