Parametric 500-series EQ module with legendary Harrison sound
The Harrison MR3eq brings one of the most famous equalizers of the 80s into a modern API 500 format. Inspired by the legendary Harrison MR3 mixing console, this equalizer module delivers the exact musical, analogue character that shaped countless classic productions. The sound is not simply clean or precise, but carries exactly that blend of warmth, presence and musical depth that makes Harrison so popular to this day.

For decades, Harrison has stood for "beautiful analog tone".
Harrison consoles have been used for albums by artists such as Michael Jackson, ABBA, Led Zeppelin, Queen and Donald Fagen. The parametric EQ of the MR3 was one of the reasons why this console established itself so quickly in large studios and with well-known producers.
With the MR3eq, you get exactly this sound aesthetic in a compact module that can be easily integrated into existing 500 series setups. This makes it particularly interesting for engineers and producers who want to combine classic console character with modern modularity.
At the center of the module is a parametric 3-band EQ with ±10 dB boost/cut. The tuning is chosen so that both surgical corrections and broad, musical shaping are possible. Instead of appearing sterile, the EQ has a pleasantly organic effect on the signal and refines the sound without destroying it.
The MR3eq really comes into its own in productions that are not just about technical correction, but about real sound.
The treble band covers a range from 800 Hz to 15 kHz and operates at 6 dB per octave. The ability to switch between shelf and bell characteristics is particularly exciting. This allows the EQ to be versatilely adapted to different sources.
This is extremely practical for airy vocals, silky overheads or a little more presence on acoustic guitars, as you can set the intervention either wide and open or more targeted, depending on the material.
The mid band works from 400 Hz to 8 kHz and has a tunable filter quality. This makes the MR3eq suitable for the targeted removal of unpleasant resonances as well as for the musical processing of important signal components.
Especially with vocals, snare, guitars or synth pads, this band helps you to make the sound either more focused or bigger without the intervention sounding artificial.
The high-pass filter with 2 dB resonance peak is a real highlight. This is no ordinary low-cut filter, but a tool with character. When cutting low frequencies, it often retains a little more musical energy in the signal instead of simply making the source sound thinner.
Especially on vocals, guitars or overheads, this can provide a clean yet lively sound.
The MR3eq offers separate bypass switches for EQ and HPF for quick work in the studio. This allows you to hear immediately how much your intervention is actually working. An input overload LED also helps you to keep an eye on the level and drive the module cleanly.
This makes the MR3eq not only attractive in terms of sound, but also practical in everyday use.
The appeal of many classic Harrison circuits lies in the fact that they not only change frequencies, but also shape signals musically. This is precisely why Harrison EQs often appear larger, rounder and more natural than many modern, very technical alternatives. The MR3eq is therefore not a sober correction tool, but rather a sound shaping device with real studio DNA.
