Universal Audio Apollo Twin X QUAD Gen 2 Essentials Audio Interface

Universal Audio Apollo Twin X QUAD Gen 2 Essentials+ Audio Interface – Desktop Thunderbolt Interface with QUAD DSP

The Apollo Twin X QUAD Gen 2 is Universal Audio’s desktop recording interface in its most powerful Twin configuration: four SHARC DSP processors onboard, two Unison microphone preamps, and the improved conversion of the Apollo X Gen 2 generation. This Essentials+ edition pairs the hardware with the Essentials+ collection of UAD plug-ins. It is a 10-input, 6-output Thunderbolt 3 interface aimed at producers and artists who record one or two sources at a time but want the monitoring quality, low-latency plug-in processing and preamp modelling of a much larger studio system.

Gen 2 brought more than a spec refresh. Conversion was upgraded, with digital-to-analogue dynamic range of 129dB for critical monitoring, and the UAD Console software gained Auto-Gain, Plug-In Scenes, bass management and Apollo Monitor Correction powered by Sonarworks, which calibrates monitor and headphone outputs for the room. Round-trip latency through Console with UAD processing is 1.1 milliseconds at 96kHz, so tracking through plug-ins feels like tracking through hardware.

Key features

• QUAD Core UAD-2 DSP for realtime processing of UAD plug-ins while tracking
• Two Unison preamps that model classic preamp impedance and gain behaviour
• 24-bit, 192kHz Apollo X Gen 2 conversion with 129dB D/A dynamic range
• Auto-Gain sets input levels automatically in UAD Console
• Built-in talkback, ALT speaker switching and monitor controller functions
• Optical ADAT or S/PDIF input expands recording to 10 simultaneous inputs

Unison preamps and inputs

Two rear combo XLR and TRS sockets accept microphones and line sources, with switchable 48V phantom power per input, a 20dB pad and preamp gain from 10dB to 65dB; microphone input dynamic range measures 123dB A-weighted. Unison technology changes the preamp’s input impedance and gain staging to match the UAD preamp emulation in use, so a 610 or Neve-style plug-in responds to the microphone the way the original hardware would. A front-panel Hi-Z input covers guitar and bass, and the optical input accepts an external eight-channel preamp over ADAT when a session outgrows the two onboard preamps.

QUAD DSP and the Essentials+ bundle

The four SHARC processors in the QUAD configuration run UAD plug-ins on the interface itself, with near-zero latency during recording and without loading the computer. QUAD provides roughly twice the plug-in capacity of the DUO version, which matters when a mix stacks channel strips, tape emulations and reverbs across many tracks. The Essentials+ edition bundles a working set of UAD preamps and channel strips, compressors, equalisers, tape and plate effects and instruments, and the library of more than 200 UAD titles remains available to add. Processing also runs natively in the DAW through the same plug-ins in VST, AU and AAX formats.

Monitoring and Console control

The large front knob controls monitor level for the stereo monitor outputs, with a second pair of line outputs available for an alternate speaker set; a stereo headphone output has its own level control. Talkback is built in for communicating with a performer, and the updated Console adds Plug-In Scenes for recalling processing setups and bass management for subwoofer integration. Apollo Monitor Correction applies Sonarworks calibration to the monitor and headphone paths, and the interface expands by linking with other Thunderbolt Apollo units as a studio grows.

System requirements and fit

The Twin X connects over Thunderbolt 3 and works with macOS and Windows computers, in LUNA and in all major DAWs including Pro Tools, Logic Pro, Cubase and Ableton Live. For a singer-producer, a two-person podcast or voice setup, or a mix position built around high-quality monitoring, the QUAD Gen 2 concentrates Universal Audio’s conversion, preamp and DSP platform into a unit that sits within reach on the desk.
