Universal Audio Apollo x6 16x22 Thunderbolt 3 Audio Recording Interface

16x22 Thunderbolt 3 audio recording interface with 2 Unison mic preamps, HEXA Core processing and Realtime Analog Classics Plus UAD plug-in bundle

Product Description

The Universal Audio Apollo X: The Evolution of Apollo Recording Interfaces

Universal Audio’s Apollo recording interface has enabled audio creators the world over to record and mix world-class compositions with greater ease than ever. The Apollo X is the next step in the impressive lineage of these interfaces and the Universal Audio Apollo x6 improves upon its predecessors with unparalleled conversion, processing and monitoring features.

Created with music producers and post-production facilities in mind, the Apollo x6 enables users to record, overdub and mix via a 16x22 (6x12 analog I/O) interface with two Unison-enabled mic preamps and new HEXA core processing. This improvement in processing power allows for 50% more DSP for running UAD plug-ins during each step of your creative process.

Packaged in a sleek rack mount unit with Thunderbolt 3 connectivity for Mac or PC, the Apollo x6 additionally offers improvements in conversion and monitoring. Once again, Universal Audio has updated their converters for more pristine recordings and now offers 5.1 surround sound monitoring, an integrated monitor controller and built-in talkback mic.

Improved Conversion For The Apollo x6

In the time since the release of the Apollo MKII interfaces, Universal Audio engineers have been hard at work on improving the conversion capabilities for the launch of the Apollo X line. Ultimately, the design team paired together 24-bit/192 kHz converters with new analog circuitry to offer Apollo x6 users pristine sounds with 129 dB dynamic range and 128 dB THD+N.

Adding More Power To The Apollo x6

The Apollo x6 offers more power than ever before with HEXA Core processing that utilizes six DSP chips. With 50% more DSP than previous generations of the interface, you’ll be able to take advantage of Universal Audio’s incredible UAD library and have a higher plug-in count when recording and mixing with the Apollo x6.

Nailing The Tone With Unison Technology

Universal Audio’s Unison Technology melds together plug-ins and analog in a way they’ve never been paired before. The Apollo x6 features two Unison-enabled mic pres, which allow music makers to track through mic pre emulations that match the actual input impedance, gain stage “sweet spots” and circuit behaviors of the gear they are based on. With legendary mic pre emulations from API, Manley, Neve, SSL and Universal Audio at the ready, you can bring the exact tone of so many classic records to next your next project.

A Seamless Fit In Any Studio

Using Apollo interfaces in a professional recording studio has never been easier. The Apollo x6 features 5.1 surround monitoring for creators working in the world of post-production, no matter whether it be for film, video games or television. There is also a selectable +24 dBU option for working outside of the box and using the Apollo x6 in conjunction with recording consoles and analog outboard gear.

Great interface!

By Damien W on May 2, 2021

So far this Apollo X6 is working out great. Once you understand the internal routing, its capacities began to surface.

My only frustrations are with the onboard talkback mic button, and the internal talkback mic itself. If you need to have this unit in a rack, the only way you can access the talkback is via the virtual console talkback button. If monitor Realestate is already an issue, this isn't going to make things easier. As for the onboard talkback mic, it works alright, but only sounds decent if you are within 1 foot of the unit. I hope that at some point, UA figures out a way to get an external mic to route through (and replace) the onboard mic and its signal. Presently, I'm using an external mic plugged into the Mic/Line 1, sending it to an Aux in ProTools, and having to un-mute and mute to turn on/off my signal. This is a viable work around, however this method lacks the Dim function that the onboard talkback system utilizes (for the prevention of feedback and echos), which can be frustrating.

Everything else is great and is fitting my needs.

Much improved ADDA

By John K on February 6, 2019

From Focusrite 18i20 to 6x, I can confidently say I went from UAD fanboy to loyal customer.

Monitoring sounds better, tracking is amazing, I think I’ll always be recommending UAD for everything now.

Now I sit patiently for more plugins!!

Just saying, I would even preorder lol.....
