Heritage Audio DTT73 Dual Tabletop 73-Style 2-Channel Microphone Preamp

Heritage Audio DTT73 Overview

  Heritage Audio DTT73 dual tabletop mic preamp front panel

The Console Sound — No Console Required

You already know what a great 73-style preamp does to a signal. That weight, that punch, that instant sense of depth that makes everything sound like it belongs on a record. The DTT73 puts exactly that on your desktop — no rack, no compromise, no excuses.

Carnhill input and output transformers, a fully discrete Class A circuit, and up to 80dB of gain mean your ribbon mics, dynamics, and condensers all get the same treatment engineers have been chasing since the early 70s. Hit record and hear the difference immediately.

As an authorized dealer, Pro Audio Reserve has you covered with a genuine Heritage Audio product backed by full manufacturer warranty and long-term support.

Heritage Audio DTT73 desktop microphone preamp studio setup

Built for the Studio, Ready for the Road

Whether you're tracking in your project room, recording on location, or sending a proper line-level signal to a FOH engineer from the stage, the DTT73 was designed to go wherever the session takes you. The internal worldwide power supply was custom-engineered to run silently alongside audio transformers — no induced noise, no compromises in the field.

Line inputs knock gain down 30dB for direct integration with front-of-house rigs, while the 80Hz high-pass filter keeps unwanted low-end rumble out of the picture. A 20dB pad on each channel means even the hottest sources stay clean without touching the output stage.

JFET DI With Thru — Play and Record Simultaneously

Each channel features an ultra-high-impedance JFET direct input that feeds the transformer for that warm, characterful DI tone you can't get from a clean buffer. What makes the DTT73 stand out on stage and in the studio is the DI Thru jack — plug in your instrument, send one signal to your amp and another straight into your DAW, with a ground lift switch to kill any hum before it starts.

Dressed in RAF blue-gray steel with wooden end cheeks and classic Marconi knobs, the DTT73 looks as serious as it sounds. This isn't a desktop toy — it's a professional tool that happens to not need a rack.

Highlights

  • Dual-channel 73-style Class A preamp with Carnhill input and output transformers
  • Up to 80dB of mic gain — ideal for ribbon mics and low-output dynamics
  • JFET DI inputs with Thru jacks for simultaneous amp and recording use
  • Internal worldwide power supply custom-engineered for silent operation near audio transformers

Shipping & Returns

  • 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.
