Heritage Audio MotorCity EQualizer Overview

  {% endif %} Heritage Audio MotorCity EQualizer mono 7-band passive EQ front panel

The Sound of Hitsville. Now in Your Rack.

The records coming out of Motown's Hitsville USA studio in the 1960s didn't just sound good — they sounded louder, punchier, and more commanding than anything else on the radio. A big part of that was the proprietary gear designed and built in-house by chief engineer Mike McLean, including the 7-band passive EQ that the MotorCity EQualizer faithfully recreates down to the last component.

This isn't a tribute or a modern interpretation — Heritage Audio had every discontinued part custom-manufactured from scratch using 100% period-correct materials, values, and tolerances. What you're getting is the actual circuit, hand-wired, in a rugged 2U chassis with a 10-gauge hand-brushed aluminum faceplate and custom-molded Bakelite knobs.

As an authorized dealer, Pro Audio Reserve ensures your MotorCity EQualizer is a genuine Heritage Audio product backed by full manufacturer warranty and support.

Heritage Audio MotorCity EQualizer rackmount studio equalizer

Seven Bands. Eight Decibels. Zero Harshness.

Frequency centers at 50Hz, 130Hz, 320Hz, 800Hz, 2kHz, 5kHz, and 12.5kHz give you precise control across the entire audible spectrum. Each band uses a heavy-duty stepped rotary switch with 1dB increments up to ±8dB — enough to make dramatic tonal moves while keeping everything sounding natural, open, and effortlessly loud.

The passive EQ circuit imparts that characteristic sense of weight and authority that engineers have been chasing for decades. Run it on individual tracks, use a stereo pair across your mix bus, or deploy it for mastering — source material takes on a presence and punch that's immediately recognizable to anyone who grew up listening to those iconic 45s.

Built Like the Era It Came From

The MotorCity EQualizer is a serious piece of kit — 15 lbs of mil-spec construction that feels as substantial as it sounds. A master gain control matches the same stepped precision as the band controls, and the In/Out/Off switch makes instant A/B comparison effortless during a session.

Heritage Audio was founded on the principle that the greatest-sounding gear ever built shouldn't be locked away in vintage shops or priced out of reach. The MotorCity EQualizer is that philosophy applied to one of the most storied pieces of American recording history — and it's finally available to you.

Shipping & Returns

  • We deliver all US orders in 3–5 business days
  • Free cancellations
  • Returns accepted within 30 days (unused items)

Order Confirmation

Once your order is placed, you will receive an order confirmation email. This confirms that we have received your order and have pre-authorized your credit card for the purchase. After confirming availability with our suppliers, we will proceed accordingly:

  • If your item is available and ready to ship within 1–2 business days, we will process the charge and arrange for shipment.

  • If your item is on backorder or unavailable, the pre-authorization will be voided and you will be notified by email.

  • Please note: While most items ship out within 1–2 business days, total delivery time is typically 3–5 business days, depending on your location and carrier handling.

Order Shipment

If your item is in stock and your payment has been processed, your order will typically ship within 1–2 business days. Total delivery time is approximately 3–5 business days from the date of order. Once shipped, you will receive tracking information at the email address provided during checkout within 24 hours of dispatch.

If you have not received tracking information within 3–5 business days of placing your order, please contact us at support@proaudioreserve.com.

The Distributor-Direct Advantage

To ensure you receive the most recent hardware revisions and 100% factory-sealed units, Pro Audio Reserve utilizes a Distributor-Direct fulfillment model. Unlike big-box retailers that may ship "floor models" or gear that has been sitting in general-purpose warehouses, your equipment is pulled directly from the primary manufacturer hub, serialized, and dispatched. This process ensures the highest level of quality control for professional-grade recording equipment.

Shipping Policy

We currently offer free shipping within the United States only. If the checkout process on our website allows you to enter a shipping address and complete your order, your location is eligible to receive delivery.

Changing Shipping Address

If you need to change your shipping address after your order has been processed or shipped, we will do our best to accommodate the request. Please note that address changes may result in delivery delays. Any additional costs incurred due to address changes, including carrier fees or rerouting charges will be the responsibility of the customer. No exceptions.

Shipping Times

All shipping times provided are estimates and should not be considered guarantees. Most orders ship out within 1–2 business days from the time payment is processed. However, total delivery time is typically 3–5 business days, depending on your location, carrier performance, and supplier fulfillment timelines.

We work closely with our vendors to ensure timely deliveries, but please note that supply chain disruptions, high-demand periods, or weather events may occasionally cause delays beyond our control.

  • To avoid misunderstandings: The “shipping time” refers to the total time from order placement to final delivery, not just when the item leaves the warehouse.

  • Cancellations: If you choose to cancel your order because it has not arrived within the estimated delivery window, you may be responsible for applicable shipping charges, restocking fees, warehouse handling costs, and other related fees.

  • Chargebacks: Customers who initiate chargebacks due to shipping delays without contacting us first may be held legally responsible for losses. We strongly encourage open communication so we can resolve any delivery concerns directly and efficiently via our Atlanta-based support team.

Delivery Options

  • Threshold Shipping: Your item will be delivered to your front door, porch, garage, or a covered entryway.
