Heritage Audio BritStrip Channel Strip Features

  Heritage Audio BritStrip 73-style channel strip diode bridge compressor

73JR Preamp Plus Expanded EQ Plus Successor Compressor

Same 3-stage Class A 73-style preamp as Heritage's 73JR with new custom Carnhill input transformer (co-designed with Carnhill, built exclusively at St Ives factory). Custom Carnhill output transformer completes the all-discrete circuit. 80 dB gain in 5 dB steps, -20 dB pad, phase reverse, 300/1,200 Ω input impedance switch.

Class A JFET DI (>2 MΩ input impedance) sits before input transformer. Passive thru output feeds amp simultaneously for reamping. EIN <-125 dBu @ 60 dB. THD <0.025% @ 1 kHz / <0.05% @ 100 Hz. Max input >+22 dBu, max output >+26 dBu into 600 Ω.

 Heritage Audio BritStrip three-band inductor EQ Vinkor pot core

Three-Band Inductor EQ With Vinkor Pot Cores

High: ±16 dB shelving at 10, 12, 16 kHz (switchable to bell/peak)
Mid: ±18 dB peaking at 360, 700 Hz, 1.6, 3.2, 4.8, 7.2 kHz (Hi-Q/Lo-Q switchable, 3 x Vinkor pot core inductors)
Low: ±16 dB shelving at 60, 110, 220 Hz (switchable to bell/peak)
HPF: 50, 80, 160, 300 Hz (18 dB/oct, Vinkor inductor)

Vinkor pot core inductors in mid band and HPF deliver extreme musicality even with heavy boosts. High/low shelf bands can switch to bell (peak) mode for more surgical control.

 Heritage Audio BritStrip diode bridge compressor blend parallel stereo link

Diode-Bridge Compressor With Blend and Stereo Link

Same diode-bridge comp from Heritage's award-nominated Successor. Threshold, ratio, release (50–400 ms + auto), fast/slow attack toggle. Blend knob for parallel compression (post-EQ only). 5-frequency sidechain filter: Off, 80 Hz, 160 Hz, 800 Hz, 3 kHz, 5 kHz. External sidechain send/return. VU meter switchable to gain reduction.

Comp inserts pre or post-EQ (button switchable). Stereo link lets two BritStrips share compression control voltage for matched stereo tracking. 24-step detented output control ensures precise stereo imaging when linking. 1U, external PSU (included). As an authorized dealer, Pro Audio Reserve ensures you receive a genuine Heritage Audio product backed by full manufacturer warranty and long-term support.

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.
