Heritage Audio has announced the MOTORCITY Equalizer. The analog, passive EQ brings back the sound of the famous equalizers used by Motown engineers. Heritage Audio says that they went to great lengths to nail the MOTORCITY sound, including having their own custom components made.
Heritage Audio MOTORCITY EQ
According to Heritage Audio, the MOTORCITY Equalizer is the first hardware recreation of the classic passive EQs used at the Motown studios in the 1960s. As such, the single-channel equalizer features a completely analog, passive design with seven frequency bands ranging from 50 Hz to 12.5 kHz. The stepped rotary switches for each band allow for up to 8 dB of cut or boost in 1 dB increments. There’s also an In/Out/Off lever that allows you to make A/B comparisons, and a master gain control, again with up to 8 dB of boost or attenuation.
Heritage Audio says that the MOTORCITY EQ was recreated from original units owned by famed Motown Engineer Michael Brauer, and that it’s “identical and fully faithful to the original design”. As many original components are no longer available (including military-spec tone capacitors and inductors), they had to have custom replacements made from scratch, which match the original components with a tolerance of just 1%. Heritage Audio claims that the result is not an approximation, but sonically indistinguishable from the original.
The Heritage Audio MOTORCITY EQ features a UTC replica input transformer with a modified turns ratio for better integration into modern setups. For the output, they’ve opted for a Carnhill-driven output line amp in place of the original’s Opamp-labs output, which appears to have been a frequent source of faults.
With its silver faceplate and the custom-molded Bakelite knobs, the MOTORCITY EQ is a great-looking unit for sure, and the specs sound really promising. If you’ve got two units of rack space and the necessary funds to spare for a single-channel EQ, this should fit the bill quite nicely.
