Harrison Audio MR3eq 500 Series Equalizer

Harrison Audio MR3eq 500 Series Equalizer

The Harrison Audio MR3eq 500 Series equalizer brings the legendary three-band parametric EQ from Harrison's classic Music Recording 3 (MR3) console into a compact 500 Series module. As a result, engineers gain access to one of the most musical EQ circuits in console history, now ready to drop into any 500 Series rack alongside their favorite preamps and dynamics processors. The low and high bands offer 6dB/octave shelving that can be switched to a second-order bell shape, while the mid band features Harrison's renowned continuously variable Q for precise, surgical adjustments or broad, colorful tonal shaping. In addition, a dedicated high-pass filter section includes a distinctive 3dB resonant peak that adds character rather than simply rolling off low frequencies. OneStopMusic South Africa stocks the Harrison Audio MR3eq 500 Series equalizer for engineers across South Africa looking to add classic console EQ tone to their 500 Series chassis.

Classic Console Tone From the Harrison Audio MR3eq 500 Series Equalizer

Whether you're tracking vocals, sculpting drums, or mixing a full session, the Harrison Audio MR3eq 500 Series equalizer delivers the warm, musical sound that made the original MR console a favorite among engineers worldwide. Each band offers up to ±10dB of boost or cut, with the high band covering 800Hz to 15kHz and the low band covering 40Hz to 800Hz, while the mid band sweeps from 400Hz to 8kHz with variable Q for fine-tuned control. However, what sets the MR3eq apart is its proportional Q behavior on the shelving bands, which allows for broad musical strokes with natural band interaction rather than harsh, clinical correction. OneStopMusic South Africa recommends the Harrison Audio MR3eq 500 Series equalizer to South African studios wanting to add a piece of console history to their outboard rack.

Harrison Audio

Harrison Audio (Harrison Consoles) is a legendary American console manufacturer with a history stretching back to the 1970s, having built large-format consoles used on countless major film, broadcast, and music projects. Today, Harrison Audio channels that console-building heritage into the D510r — a flexible 500 Series rack system designed to turn a collection of 500 Series modules into a fully networked, Dante-ready studio or broadcast rig. As a result, Harrison Audio's interface cards and rack systems are built for facilities that need to bridge classic analog outboard gear with modern AoIP (Audio over IP) workflows. In addition, Harrison's AKM-based conversion and redundant networking options reflect the same reliability standards expected of broadcast-grade consoles. Whether you're building a Dante-networked 500 Series rig for a studio or a touring rack, Harrison Audio's interface cards make analog-to-network integration straightforward. OneStopMusic South Africa stocks Harrison Audio interface cards and rack systems for studios and broadcast facilities across South Africa.
