Universal Audio Apollo Twin X QUAD Gen 2 Thunderbolt audio interface front panel

Elite-Class Conversion That Helps You Commit Faster

Universal Audio designed Apollo Twin X QUAD Gen 2 to deliver the lowest distortion and widest dynamic range of any Apollo Twin to date. That shows up immediately when you are setting mic placement, shaping a vocal chain, or balancing synth layers, because what you hear is stable and clear.

When the front end is trustworthy, you spend less time chasing problems and more time making decisions that translate to cars, earbuds, and real studio monitors.

Real-Time Unison Tracking with QUAD Core DSP

Apollo Twin X QUAD Gen 2 gives you Unison preamps, which let you track in real time through faithful models of classic gear while the interface adjusts the preamp behavior to match the target hardware. That means your microphone interacts naturally with the input, and you can dial tones quickly without the feeling of “software after the fact.”

The onboard QUAD Core DSP also lets you run UAD plug-ins while tracking with near-zero latency, and it pairs smoothly with native processing on your computer for a flexible hybrid setup.

Monitoring Tools That Fit Modern Rooms

Apollo Twin X QUAD Gen 2 includes full monitor control with speaker switching and integrated talkback, plus features that help you work confidently in less-than-perfect spaces. Apollo Monitor Correction is available as an optional add-on for calibrated listening, and Bass Management helps integrate a subwoofer so low-end decisions are easier to trust.

Add Auto-Gain for quick level setting across multiple inputs and Thunderbolt 3 speed for low-latency performance, and the Universal Audio Apollo Twin X QUAD Gen 2 becomes a strong long-term centerpiece for a serious desktop studio.

Key Highlights

  • Desktop 10-in/6-out Thunderbolt 3 audio interface with UAD-2 QUAD Core DSP
  • 24-bit/192kHz conversion with elite-class AD/DA design
  • Unison preamps for real-time tracking through classic hardware models
  • Hybrid workflow combines onboard DSP with native processing
  • Monitor control with speaker switching, talkback, and Auto-Gain support
  • Optical input supports ADAT and S/PDIF for expandability

Shipping

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.
