Classic Harrison 32 Series EQ for Your 500 Series Rack!

The 32EQ is the result of a close collaboration between Great River and the original designers of Harrison's 32 Series consoles. The result is the 32EQ - a faithful reproduction of the legendary equalizer and filter based on Harrison's exact schematics that sounds and behaves just like the original. Even better, the 32EQ's modular design integrates directly into the highly popular 500 series rack format. That way, you can incorporate this vintage equalizer conveniently into an configuration with other incredible components to achieve the perfect sound chain, which makes the EQ32 even more versatile than conventional signal processors.

Get the real, vintage sound of the legendary Harrison 32 Series console equalizer

Great River worked directly with the original designers at Harrison who developed the first 32-bus "in-line" recording consoles from which the "32 Series" console derived its name. These consoles were responsible for countless hit records during the birth of modern pop, including Abba, Queen, and both Janet and Michael Jackson. In fact, within the EQ32 is the same technology that shaped the sound of Michael Jackson's Thriller, the best-selling album of all time. And with the 32EQ, you can bring that same powerful technology into your 500 series rack.

Plug into the power and versatility of the 500 series rack

There are some things that make the 32EQ even better than the original Harrison 32 Series console equalizers - namely the freedom the that 500 Series rack gives you from a giant mixer. With a 500 series rack, you can partner the 32EQ with a wide assortment of other, world-class modules like vintage preamplifiers and dynamics units. And while the 32EQ delivers large-format sound, its small-format price makes it easier to get your hands on the all the rest of the components you want.

Great River 32EQ Modular Vintage-style Equalizer Features at a Glance:
  • Low, low-mid, hi-mid, and high bands with gain and frequency controls
  • Low and high band "peaking" switches
  • EQ in/out switch
  • Harrison's renowned highpass and lowpass filters with sweepable frequency
  • Filter in/out switch
  • An internal jumper provides selection of the "vintage" feedback design and non-feedback option.
Add a vintage touch to your 500 series rack with Great River's 32EQ!

True Believer

It took me a while to integrate these into my workflow. The most significant thing about them is that when I do incorporate them into a mix, the clarity of the track and the ability to isolate each track's sweet spot in the mix is superbly easy and audible. Through my own laziness, I generally have relied on my DAW's EQs due to the ease in which they can be added. Using these EQs, I have to patch them in. I only have two of them, thus I also have to re-record a track back into the project. This is why I tend to get lazy. But, when I go through the effort, the sonic difference between these and the "in-the-box" EQs is amazing.

I write this as I swallow my pride with these EQ processors. I had tried going towards other brands (i.e. Maag, API) folks this EQ processor allows the user to easily access the low/mid/high frequencies and its really great once you get that EQ setting just right. Well I've been testing various EQ's for vocals on ribbon microphones and without a doubt I can say for certain that the Great River Harrison EQ's are the best hands down. There are others I'd like to try but the moral of the story stick with what you bought first instead of going on some wild goose chase trying to find that ever allusive sound as it were. Face it chances are if it doesn't sound right its probably something you or me are doing. That being said, I highly recommend these EQ's and I will cherish them.

so good I bought another one

I love this eq. The feature set is amazing for a 500 series eq with hi/low pass, 4 bands and q or shelf on the top and bottom bands. This eq has performed stellar for me on everything. Great for cleaning up a vocal, adding a little umph to drums, or sweetening program material. When I looked to get another eq for my lunchbox I found the one I had so versatile I ended up just getting another and will probably continue till I have 6 to 8 of these bad boy's.

an incredibly good eq

so I was on the lookout for a VPR EQ that had: atleast 3 bands, both fixed LP and HP and in/out buttons. this is it. really, look no further, grab this and you will be happy. its as creamy as the best icecream.

Excellent EQ

First let me say that this piece is built like a mini-tank! It's by far the heaviest 500 module of all that I have. Solid, needless to say. Love this EQ for tracking vocals. Once you get the sound you want and record it, I found I barely do any other EQ to the vocal unless its subtractive. The filters on this unit are excellent! I've A/B the EQ 32 to the UAD Harrison EQ and matched settings as close as possible and the EQ 32 BLOWS it out of the water! Its most evident when you compare the filters! It's not even close. Great unit, great price, great addition to my lunchbox. I think you'd enjoy it as well.
