$ 399.99

The Harrison Audio MR3eq 500 Series EQ takes the popular 3-band parametric EQ found on the classic Harrison Music Recording 3 (MR3) console and delivers it in 500-series format. Proving equally effective in both tracking and mixdown scenarios, The MR3eq's flexible design and powerful sculpting capabilities can be used to enhance a wide array of source materials while delivering the warm, rich Harrison tone that helped create some of the most iconic albums of the 70s' and 80s'.

Legacy in Analog
  • Harrison consoles have helped create some of the most highly regarded and influential music in history. Michael Jackson, ABBA, Led Zeppelin, Queen, Donald Fagan, and many more iconic artists have relied on Harrison production tools to help create their multi-platinum albums.
  • The latest range of 500 series modules from Harrison harnesses the sound and features that engineers like Bruce Swedien, Roger Nichols, and Reinhold Mack trusted to make music that stands the test of time.

MR3eq EQ Design
  • The MR3eq is a high-performance analog EQ, crafted from Harrison's decades of experience in equalizer and filter design. The circuit design of this EQ allows for sound sculpting with surgical precision or the creation of broad musical strokes with lots of band interaction for a rich and colorful sonic character.

3-Band Parametric with HPF
  • This powerful 3-band parametric equalizer features low- and high-frequency 6 dB/octave shelf bands, which can be switched to a 2nd-order bell response with Harrison’s renowned proportional Q.
  • The mid-frequency band offers a continuously variable Q, while a separate high-pass filter section includes a distinctive 3 dB resonant peak.
