Universal Audio Apollo Range Audio Interfaces

Universal Audio is known for their powerful UAD plugins and amazing audio interfaces, which are available in rack or desktop versions depending on the size of your setup. The interfaces have Unison preamps, and the secret to Unison’s brilliance is the hardware-software integration between Apollo’s mic preamps and it’s onboard Realtime UAD processing.

Apollo X

The Apollo X Range includes the X4, which has a DUO Core processor, and X6, X8, X8P and X16, which are rack-mountable, and have HEXA Core processors.

The Apollo X series also has new Dual-Crystal clocking, with dedicated crystal oscillators for 44.1/88.2/176.4 kHz and 48/96/192 kHz sample rates —resulting in extremely low jitter, measured at less than 10 picoseconds at all sample rates. For you, this means pure, artifact-free recordings and solid stereo imaging.

Thunderbolt connectivity and real time processing means there will be almost zero latency. Apollo X series audio interfaces work with all major DAWs.

Overview by GAK

The Apollo X8 Thunderbolt 3 is a 18x24 audio interface that has 4 Unison-enabled preamps giving you authentic tones from Neve, API, Manley, SSL, and more. The interface uses A/D D/A converters with newly designed analog circuitry to give you the lowest signal-to-noise ratio, between 129 dB dynamic range and -118 dB. It’s a great interface for producers and engineers that work on music and audio for TV, video games, and the web.

You can connect with various professional-level studio gear with the switchable +24 and +20 dBu headroom settings, work in 7.1 surround sound, and built-in talkback allows you to communicate easily.

The Realtime Analog suite is included, with analog and digital sounds from Marshall Plexi Ampeg, Pultec EQ, and Fairchild 670 tube compressor. There’s also lots of effects such as distortion, compression, reverb, and delay.

You can combine the Apollo X8 with up to four more Thunderbolt-equipped Apollos if you need more inputs and outputs, and the X8 benefits from backwards compatibility with Thunderbolt 1 and 2.

*Please note - Thunderbolt cable is not included.

  • Simeon Matthews


    The Universal Audio Apollo X8 is an absolutely fantastic interface. I have had some experience with the "Unison Preamps" before and let me assure you. These things are incredible. if one preamp doesn't suit a vocalists timbre. Two clicks of the mouse and its different. Not only that. They're a very excitable singer. One second they're soft ,next they're belting it out. No problem. just drop a compressor in UAD's Console channel strip. Sorted. The plugins that UAD do are incredible. This is truly a professional audio interface.
