Product Description

What's the difference between this and the Apollo X HE version?

Apollo X rackmounts are exactly the same as the Apollo X HE variants. The only difference is that the HE variants come with the set of Heritage Edition plug-ins. This lets you choose between the two Apollo interfaces at either a lower or higher price, depending on your budget. 

World-Class Sound

The Universal Audio Apollo x6 is a truly world-class audio interface packed with the very best features in sound quality, processing and preamps. 

UA have 60 years of audio knowledge and thousands of chart-topping record experience packed into their flagship rackmount X series. This 16x22 interface boasts completely new and future-proof A/D and D/A conversion, Unison preamps and HEXA Core processing. The Apollo challenges to be the very best at any price for professional recording.

Compatible with Mac and PC.

Sample rate and bit depth

The Apollo x16 uses 24-bit/192 kHz A/D/A converters with newly designed analog circuitry to deliver optimum audio quality between 129 dB dynamic range and -118 dB. This has some of the lowest signal-to-noise ratio of any interface ever created.

You’ll have as close to zero latency possible in your signal path using Thunderbolt connectivity and real time processing. Guaranteed to cut out tracking lag and attain 50% more DSP performance when running multiple UAD plug-ins. 

There’s plenty of versatility too with switchable +24 and +20 dBu headroom settings. This allows you to connect with varying pro-level studio gear when needed. You can also work in 5.1 surround sound using speaker calibration, to get the most authentic listening experience. Integrated talkback allows for built-in cues and easy communication.

If ever you need more I/O’s, combine with up to four more Thunderbolt-equipped Apollos. The x6 benefits from backwards compatibility with Thunderbolt 1 and 2. 

Surround Monitoring and Dual-Crystal Clocking

With comprehensive 5.1 surround monitoring support, Apollo x6 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x6 offers selectable +24 dBu operation for out-of-the-box compatibility with professional mixing consoles and other high-end pro audio equipment.

The Apollo X series also introduces new Dual-Crystal clocking —featuring dedicated crystal oscillators for 44.1/88.2/176.4 kHz and 48/96/192 kHz sample rates —resulting in stunningly low jitter, measured at less than 10 picoseconds at all sample rates. This translates into pure, artifact-free recordings and solid stereo imaging you can trust.


Expect a huge dynamic range headroom and a natural, crisp voicing from the elite Unison preamps. Emulate the likes of Neve, API, Manley and more using the intuitive plug-in. You'll have access to input impedance, gain stage “sweet spots,” and the  component-level circuit behaviors of the original hardware.   

The secret to Unison's excellency is its hardware-software integration between Apollo’s mic preamps and its onboard Realtime UAD processing. 

Included is the Realtime Analog Classics Plus Bundle plug-in for a huge array of tonal options. Featuring Marshall Plexi Ampeg, Pultec and Fairchild modelling EQ. You can get stuck in with plenty of effects too, such as expertly programmed compression, distortion, reverb and delay.

The Apollo x6 is compatible with all major DAWs, such as Pro Tools, Logic, Cubase and Ableton.

Your recordings will improve greatly with the rich, three-dimensional analog sound provided by the likes of Pulteq EQ for guitars and a Fairchild 670 tube compressor on drums.

LUNA DAW Included

Mac users of Thunderbolt-equipped Apollo can now use Universal Audio's digital audio workstation, LUNA. Apollo interfaces are fully compatible with any DAW of your choosing, but UA have designed LUNA to specifically get the most out of the Apollo series. With Accelerated Realtime Monitoring for seamless hardware-software integration, you can capture audio through UAD plugins with virtually no latency. UA have worked with some of the biggest names in audio to load LUNA with great sounding instruments and extensions. Enjoy high-quality extensions such as the Studer multitrack tape and Neve Summing, as well as instruments from Moog, UA, Spitfire Audio and more!
