Heritage Audio MotorCity EQualizer Review
Heritage Audio, a professional audio producer, primarily based in Madrid, Spain, released a trustworthy replica of McLean’s EQ, which they’ve named the MotorCity EQualizer. As a reference, Heritage used authentic variations of the unit, which have been lent to them by legendary producer and mix engineer Michael Brauer. Because many of the parts were no longer accessible, Heritage Audio created custom re-creations that matched the tolerances of the originals, with lower than 1% variation.
The MotorCity EQualizer is a totally analog, passive EQ design with seven accessible frequency points throughout the tonal spectrum. From the 10-gauge hand-brushed aluminum face plate, and traditionally accurate management structure including custom molded bakelite knobs, the MOTORCITY Equalizer seems to be the part.
The Heritage Audio MOTORCITY EQ contains a UTC replica input transformer with a modified turns ratio for better integration into trendy setups. For the output, they’ve opted for a Carnhill-driven output line amp instead of the unique’s Opamp-labs output, which seems to have been a frequent source of faults.
Heritage describes the end result as a ‘dead nut’ replication of Michael Bauer’s units, however with one deliberate exception: they selected to use a tried‑and‑trusted Carnhill transformer for the output stage somewhat rather than try to copy the unique’s op‑amp. Why? Largely because that op‑amp acquired a reputation for being unreliable and the Achilles’ heel of the unique design!
More importantly, the distinctive passive equalization circuit is equivalent and completely devoted to the unique design, together with custom construct mil-spec 1960’S tone capacitors and inductors. The Heritage Audio MOTORCITY Equalizer delivers the identical unmistakably big, punchy, and warm signature sound, making this EQ as traditional as the hits it helped create.
The 2U, single-channel MotorCity EQualizer options bands of 50 Hz, 130 Hz, 320 Hz, 800 Hz, 2 kHz, 5 kHz, and 12.5kHz. It permits you to boost or cut each by as much as 8 dB, in 1dB increments, utilizing the heavy-duty, detented rotary switches, which you regulate with massive, custom-molded Bakelite knobs.
The other controls on the unit are a 3-way switch that turns on and off the power and allows you to toggle the EQ between on and bypass, which is ideal for A/B comparisons. An output Gain management and an old-style, jewel-light power indicator round out the entrance panel.
All rotary switches have easy-to-read from a distance “General Radio” bakelite type knobs recreated to look precisely just like the originals. Lastly, it contains a master gain management (-8db/+8db) with 1dB increments. The straightforward 1960s accurate back panel contains a power provide jack for the exterior energy supply, and an XLR input and output.
The sound of the MOTORCITY EQualizer is precisely what you’d count on. It is a force without sounding sharp or misshapen. Or as Michael Brauer says: It simply has that sound! The Heritage audio MOTORCITY EQ is not a digital equivalent, not a respectfully close duplicate, and never a more appropriate modernized “improvement.” The MotorCity EQualizer is nothing roughly to the genuine article lastly made accessible for the general public.
With its silver faceplate and the custom-molded Bakelite knobs, the MOTORCITY EQ is a great-looking unit for certain, and the specs sound actually promising. In the event you’ve got two items of rack space and the required funds to spare for a single-channel EQ, this could match the bill fairly nicely.
