TK Audio DP3 2-channel microphone preamp front panel

One Preamp. Four Completely Different Sounds.

Most mic preamps give you one sound and ask you to work with it. The DP3 gives you four. Start with the Swedish Lundahl-loaded input stage — up to 80dB of clean, transparent gain that gets out of the way and lets your microphone do the talking. Then flip on the Carnhill-loaded Class A stage and suddenly you're in the territory of a classic British console: fat, punchy, and unmistakably characterful.

Need more? The selectable saturation circuit adds odd harmonics for edge and presence, while the germanium circuit softens the top end and introduces both odd and even harmonics for a rounder, more vintage texture. These aren't subtle mode changes — they're genuinely different tools, all living in one 1U box.

As an authorized dealer, Pro Audio Reserve ensures your TK Audio DP3 is genuine, backed by full manufacturer warranty and support.

Drive the Transformer. Protect Your Converter.

Here's where the DP3's design really shows its intelligence. The dedicated Output level control sits after the Class A stage, meaning you can push the Carnhill transformer as hard as you want — dialing in exactly the saturation and harmonic content you're after — without sending a clipped signal into your A/D converter. It's a feature that sounds simple but changes everything about how you use the preamp.

Whether you're recording at unity gain for a clean capture or driving the transformer into rich, harmonically complex territory, the DP3 keeps your gain staging completely in your hands from input to output.

Every Feature You Actually Need — Nothing You Don't

A sweepable high-pass filter from 30Hz to 400Hz gives you precise low-end control rather than fixed cut points that may or may not suit the source. Selectable input impedance toggles between 1,600 and 400 ohms to pull a different character out of your microphones, and 48V phantom power, a -30dB pad, and polarity invert handle the everyday demands of any session.

The hi-Z DI input on each channel stays connected and ready without interfering with mic input use. Activate hi-Z direct mode to bypass the input transformer entirely and add +14dB of gain — a particularly effective combination with the Class A stage for recording DI bass with real transformer grit. An 8-LED headroom meter and illuminated switches keep everything readable at a glance.

Highlights

  • Dual-channel mic preamp with Lundahl input transformer delivering up to 80dB of transparent gain
  • Switchable Carnhill-loaded Class A stage for classic British console punch and character
  • Selectable saturation and germanium circuits for additional harmonic shaping options
  • Post-Class A Output level control for driving transformers without overloading your converter
  • Sweepable HPF (30–400Hz), selectable impedance (400/1,600 ohms), hi-Z DI with direct mode bypass

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.
