Universal Apollo x4 Gen 2 Thunderbolt Audio Interface

SKU CH-YVG9-JJV9P

A desktop audio interface with four Unison mic preamps, Thunderbolt 3 connectivity, 24-bit/192 kHz conversion, 1.1 ms latency at 96 kHz, and an included Essentials+ UAD plug-in bundle

  • Pristine audio quality with 24-bit/192 kHz resolution for professional recording accuracy
  • Ultra-low latency of 1.1ms at 96 kHz via Thunderbolt connectivity for real-time processing
  • Versatile connectivity including 4 XLR mic inputs, 2 Hi-Z instrument inputs and ADAT/S/PDIF digital I/O
  • Essentials+ plug-in bundle provides classic studio processors and effects for professional sound shaping
  • Four Unison preamps with impedance-matched analog modeling for authentic analog equipment tone

Professional desktop audio interface

The Universal Apollo x4 Gen 2 is a Thunderbolt 3 audio interface built for music producers and audio engineers who demand studio-grade conversion and real-time UAD plug-in processing in a compact desktop form factor. Its four Unison preamps and elite-class Gen 2 converters deliver the dynamic range and analog texture required for professional recording and mixing sessions.

Simple Thunderbolt connection and driver setup

Installation centres on a single Thunderbolt 3 cable and the Universal Audio software installer, which handles firmware and the Essentials+ plug-in bundle in one workflow. The main friction point appears when the host computer lacks a native Thunderbolt 3 port; adapters or docks that do not carry full Thunderbolt protocol will prevent the interface from enumerating, so buyers without a certified port should verify compatibility before purchasing.

Thunderbolt 3 bandwidth and host requirements

The interface relies on Thunderbolt 3 for its 1.1 ms round-trip latency at 96 kHz and 24-bit/192 kHz conversion, meaning the host must provide a genuine Thunderbolt 3 controller with sufficient PCIe lanes — USB-C ports that only support USB or DisplayPort Alt Mode will not work. Session size is ultimately limited by the computer’s CPU and memory rather than the interface itself, so very large projects with heavy UAD plug-in counts may hit system bottlenecks before the hardware does.

Questions about this item

How can I confirm the Apollo x4 Gen 2 is performing at its specified 1.1 ms latency after setup?

Verify the Thunderbolt 3 link is active in your system settings, set the session to 96 kHz, and monitor the UAD Console round-trip readout; it should sit at or below the quoted figure.

What comes in the box with the Apollo x4 Gen 2 and what must I purchase separately?

The unit ships with the Essentials+ UAD plug-in bundle; you will need to supply Thunderbolt 3 cables, microphones, instruments, and any ADAT or S/PDIF optical cables your workflow requires.

Which version of the Apollo x4 Gen 2 should I choose for 24-bit 192 kHz conversion and four Unison preamps?

The single model described delivers 24-bit 192 kHz resolution, four Unison mic preamps, two Hi-Z inputs, and ADAT/S/PDIF I/O, so no alternative version or capacity selection is necessary.
