Antelope Audio Zen Quadro Synergy Core on desk with laptop showing dual USB-C connection for two-system setup

One Box. Two Computers. Every Creative World Connected.

Most audio interfaces talk to one computer. The Zen Quadro talks to two simultaneously. That single design decision is what separates it from everything else in its price range and makes it the right tool for a specific type of creator who has outgrown the idea of a single-machine setup.

The primary USB-C port handles your main DAW or streaming machine. The secondary USB-C port connects a second computer, a phone, or a tablet at the same time via OTG, with full bidirectional audio routing between both devices. For a dual-PC streaming setup, that means your game audio and your microphone signal can route independently to your broadcast machine without capture cards or virtual audio cables doing unreliable work in the background. For a two-host podcast, both hosts get their own headphone mix from the same box. For a mobile producer moving between an iPad and a MacBook, the Zen Quadro bridges both without a second interface on the desk. The secondary port also charges a connected mobile device while it streams audio, which eliminates one cable from an already complicated setup.

130 dB Dynamic Range. Galaxy-Class Converters. Bus-Powered.

Antelope's flagship Galaxy interfaces are what major recording studios use when conversion quality is non-negotiable. The Zen Quadro uses the same AD/DA converter chips from that Galaxy line, which is not a marketing comparison: it is the same silicon, in a bus-powered desktop box that runs off a single USB-C cable. The D/A dynamic range hits 130 dB with THD+N at -115 dB. The A/D comes in at 122 dB with THD+N at -116 dB. At 24-bit/192kHz across all sample rates from 32 to 192kHz.

Those numbers matter most when you are monitoring. The 130 dB D/A stage is what you are listening through every time you play back a mix, check a vocal, or reference a master. Cleaner conversion means the decisions you make based on what you hear are decisions based on what is actually in the recording, not on conversion artifacts introducing noise or smear at low levels. The 64-bit Acoustically Focused Clocking technology underpins all of it: fourth-generation AFC runs 64-bit DDS jitter management across every sample rate, keeping the clock source stable regardless of what else is running on the USB bus.

37 FPGA Effects, 48 Simultaneous Instances, Zero CPU Load

The Synergy Core processing engine is not a DSP chip running emulations. It is a combination of FPGA and DSP working together, where Antelope's engineers modeled individual circuit components of analog hardware rather than approximating the overall sound. The difference in approach shows up in how the effects behave dynamically, which is what separates a faithful model from one that sounds correct at one setting and wrong at another.

Thirty-seven effects ship included: vintage compressors, EQs, guitar amps and cabs, modulation effects. Up to 48 mono instances can run simultaneously across 6 input chains with zero CPU load on either connected computer. For a Twitch streamer running a game and a broadcast encoder, that is meaningful. For a producer tracking vocals with a modeled Neve preamp and an 1176 on the way in, it means the heavy lifting happens in the Zen Quadro's hardware while the DAW handles arrangement and mixing. The color display provides full standalone access to routing, mixer controls, and preset recall without opening any software, which also makes the Zen Quadro a viable live performance FX processor when the computers stay home. DC-coupled inputs and outputs handle control voltage signals for hardware synth integration, and ADAT I/O expands the channel count to 14 in and 10 out total when external digital sources are connected.

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.
