Maag Audio EQ4-500 500 Series 6-Band Equalizer - Black

Based on the acclaimed EQ4M mastering equalizer, the Maag Audio EQ4-500 introduces key enhancements. The front panel features bold new labeling and an updated visual layout with an iconic Maag Audio blue faceplate, designed to improve visibility in studio environments. Increased spacing between the frequency knobs improves ergonomics, allowing for easier and more precise control, especially during fast-paced sessions. The module also includes a true hardwire bypass circuit, identical to the one found in the EQ4M, ensuring complete signal transparency when the EQ is disengaged.

6 EQ BANDS

Like the 1U standalone EQ4M, the EQ4-500 includes six EQ band sections: four fixed-frequency bell-shaped peaking bands, a 2.5 kHz shelving band, and the renowned Air Band, with selectable frequencies at Off, 2.5, 5, 10, 15, 20, and 40 kHz. The five main frequency bands (Sub at 10 Hz, 40 Hz, 160 Hz, 650 Hz, and 2.5 kHz) offer up to ±15 dB of boost and as much as -4.5 dB of cut, with center detents at 0 dB for quick recall. The Air Gain control provides up to +20 dB of boost in the high-frequency shelf.

THE ULTIMATE EQ FOR YOUR 500 SERIES RACK

Additional features include a green signal-present LED that activates at -20 dBu and a red peak LED that illuminates at +23 dBu. An In/Out bypass switch allows easy engagement or disengagement of the entire EQ section. Whether you’re tracking or mixing, the EQ4-500 delivers smooth, musical equalization with unmatched clarity—especially when shaping the top end using Maag’s Air Band. With thoughtful updates and proven sonic performance, the EQ4-500 is the ultimate equalizer for any 500VPR rack owner and a reliable tool for enhancing everything from individual tracks to full mixes.
