MOTORCITY EQUALIZER

MOTORCITY EQUALIZER

Occasionally, something so special arrives, it turns the music industry Upside down (and inside out). That is why Heritage Audio is incredibly pleased to offer the world’s  first reproduction (and a dead on one at that) of the “Holy Grail” of classic EQ’s. The “MOTORCITY EQualizer”.

Recreated from  Motown units owned by Eight-time Grammy winning producer, mixdown artist, and innovative engineering genius Michael Brauer, Heritage Audio has left no stone unturned, recreating the unmistakably huge, punchy, and warm signature sound that makes this EQ as classic as the hits it helped create. From the 10-gauge hand brushed aluminum face plate, historically accurate control layout including custom molded bakelite knobs, the MOTORCITY Equalizer looks the part. More importantly, the unique passive equalization circuit is identical and fully faithful to the original design. The MOTORCITY EQualizer is so precise, it stands as the only EQ available that can rival, or even “best” the popular Pultec EQ.

It was no simple task to make a 100% accurate reincarnation. Peter Rodriguez and his team from Heritage Audio worked for weeks with their friends at Black Lion Audio. Seth Berman from Black Lion Audio’s NY facility took the lead in getting the info together for Heritage to work their magic. Everything was complicated by the 2020 summer lockdowns in Europe and the US, but they got it done! The exceptionally tight mil-spec 1960’S tone capacitors and inductors are simply no longer available. Replace with a alternate? Not on your life. Heritage Audio had custom recreations built from scratch. Each with exact materials, values, and tolerances:  A perfect interchangeable clone of the very few originals remaining. Just add 60 years of dust, and you’ve got twins

Description:

The MOTORCITY EQualizer is a completely analog, passive EQ design with seven accessible frequency points across the tonal spectrum. Each frequency has a stepped rotary switch capable of a flat response, or up or down up  8db in 1dB increments. Frequency points graduate from 50hz, 130hz, 320hz and 800hz before jumping to 2000hz, 5000hz, peaking at 12,500hz. The front panel also features a simple in/out/off toggle switch with top hat knob and jewel light power indicator. All rotary switches have easy to read from a distance “General Radio” bakelite style knobs recreated to look exactly like the originals (remember, this is not a slider-style graphic EQ). Finally, it features a master gain control (-8db/+8db) , again in 1dB increments. The incredibly simple 1960’s accurate back panel features a power supply jack, and an XLR input and output. The sound itself is exactly what you’d expect. It packs a punch without sounding harsh or distorted. While something as simple as an analog seven band EQ might sound more like hype than hyper goodness, hearing is believing. Why has Heritage audio gone through the seemingly impossible task of bringing them back to life? Michael Brauer will tell you this: It simply got that sound! The Heritage audio MOTORCITY EQ is not a digital equivalent, not a respectfully close replica and not a more compatible modernized “improvement.” The MOTORCITY EQualizer is nothing more or less than the genuine article finally made available for the general public.. For the very first time in history, you can integrate this true spec to spec carbon copy of both form and function into your own studio.

Can’t go wrong with a Heritage Audio 73 Jr

Well, I´ve finally gotten around to writing a review for this absolutely stellar preamp… it only took me three years! At least you know that I actually had time to give it some use before writing my review. Since, winning my 73Jr in an online writing contest, it has made valuable contributions to all of my recordings. Everything about the 73Jr is well made and I can’t say enough about its build quality. It´s based on the vintage 1073 preamp and it adds a warm, creamy clarity to vocals and it makes digital keyboards/synthesizers sound less digital before hitting the DAW. My 73Jr does what it is meant to do and it does it flawlessly. BONUS: when pushed it adds some really sweet breakup to clean guitar. I never imagined that a mic preamp could actually contribute to a recording… I mean, all they do is raise the volume of a signal, right? Hahaha! I was wrong and I’m glad I was wrong! Had I not won my 73 Jr in a contest, I would have never found out how truly necessary a good preamp is to making a quality recording. I have to admit that, my first thought was to sell it for some quick cash – I didn’t own a Lunch Box and my prize was going to require the purchase of a Series 500 chassis. But, ha! I’m a gear freak and the 73Jr now sits next to an harmonic exciter and a compressor. I’m glad I spent the money on a Lunch Box because the 73Jr is a keeper!!!! If you are in the market for a 500 Series preamp, the Heritage Audio 73Jr will make you a very happy camper.

Awesome!
It´s a truly special unit. It´s a best in class considering its price, having ahpf, and line in onboard. Without all of those things it still wins, as it´s exactly what you´re looking for sound-wise. I´ve tried several other sub 1k iterations of this circuit. Up until now, nothing has gotten me this close. Shines on vocals, and synths. I´m frantically trying to save to get another unit, and will eventually add the eq’s as well. This is the real deal folks. My Sweetwater Rep, Brian Loney was dead-on with this one!

Incredible Classic Piece
It’s the real deal… been tracking vocals on this thing with an SM7b and Warm Audio 1176 after in the chain before printing in Protools… excellent. Just recently tracked a kick drum with it and it was surprising very transient and punchy accompanied with API 550A/560 EQ within the Protools DAW. Incredible piece that is a MUST in your U-rack.

Saturation
I’m completely loving this preamp after a couple of weeks of ownership. Dialing in a good sound is straightforward. I have gotten thickly saturated sounds from a DI improving tone on my Fender P bass and allowing the bass to be heard easily in a mix. Playback on my iPhone speakers still produced the clear sound of the bass recordings. With a cheap mic I was able to dial in a clean sound by keeping the input transformer subdued and cranking the squeaky clean output transformer. By the way, the pad is in the chain before the input transformer so engaged you can crank the input harder. Also lots of success with my Alpha Juno 2 analog synth. It sounds huge. I will likely invest in the 73eq down the line. Tone galore.

Absolutely Gorgeous Sound
Can´t go wrong with this Pre. The amount of tonal variation the gain knob provides will make it easy to fit any source you throw at it. Great on Vocals – just sounds simply expensive. I usually record guitars direct and this thing gave my Axe Fx 2 a new life. ( Never thought the sound of the Axe fx needed any more but this preamp just gives the sound an extra level of clarity ) Can’t wait to get at least another one of these units for a stereo pair.
