Universal Audio Apollo x16 16x18 Thunderbolt 3 Audio Recording Interface

16x18 Thunderbolt 3 audio recording interface with 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

The Apollo X series from Universal Audio sees the brand pushing their flagship audio interface further forward than ever before. With the Universal Audio Apollo x16, recording engineers and producers will have more connectivity, unparalleled processing power, improved conversion and expanded monitoring features for their studio rig.

Apollo x16 will find a perfect fit in professional recording studios, as it enables audio creators to track and mix through a 16x18 (16x18 analog I/O) interface with new HEXA core processing. With six SHARC DSP processors, the Apollo X series now allows for 50% more DSP for running UAD plug-ins when working on audio tracks on Mac or PC.

The Apollo x16’s sleek rack mount unit features Thunderbolt 3 connectivity and also has new improvements in conversion and monitoring. Universal Audio engineers have updated their converters for more natural sounding recordings and now offers up to 7.1 surround sound monitoring*, an integrated monitor controller and built-in talkback mic.

Improved Conversion For The Apollo x16

Universal Audio has improved the Apollo interfaces conversion capabilities for the launch of the Apollo X line. For the Apollo x16, the engineering team at Universal Audio paired together 24-bit/192 kHz converters with new analog circuitry to offer best-in-class conversion with 133 dB dynamic range and THD+N of -129 dB

Adding More Power To The Apollo x16

The Apollo x16 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 extensive UAD library and have a higher plug-in count when recording and mixing with the Apollo x16.

A Seamless Fit In Any Studio

Using Apollo interfaces in a professional recording studio has never been easier. The Apollo x16 features up to 7.1 surround monitoring for engineers, producers and musicians working in any type of studio setting. There is also a selectable +24 dBU option for working outside of the box and using the Apollo x16 in conjunction with recording consoles and analog outboard gear.

Utilizing The Realtime Analog Classics Plus Bundle

Universal Audio has been one of the leaders in creating plug-in emulations of classic gear since they first re-founded in 1999. When purchasing the Apollo x16, you gain instant access to the brand’s Realtime Analog Classics Plus Bundle, which features 16 world-class plug-ins. You’ll get Universal Audio staples like the featuring UA 610-B Tube Preamp (Legacy), UA 1176LN Limiting Amplifier (Legacy), Pultec EQP-1A EQ (Legacy), Fairchild 670 Compressor (Legacy), Marshall Plexi Classic, Ampeg SVT-VR and so much more.

Building A Networked Studio With The Apollo x16

If you’re looking to build out a networked studio, the Apollo x16 is the perfect option for a centerpiece. The interface offers 16x18 inputs/outputs (16x16 analog I/O) and two built-in Thunderbolt 3 ports. These Thunderbolt 3 ports can be used to combine Thunderbolt-compatible Apollo Twins or other rack mount Apollos with your Apollo x16 and increase I/O and DSP. In total, it’s possible to combine up to four Apollos and six total UAD-2 devices with the Apollo x16.

Great interface! Also appreciate that I was able to trade in older gear. Thx Vintage King!

By Gino S on March 12, 2021

Love the Apollo line up. Decided to upgrade from a Black Face 8P to the X16 through VK’s trade up program. Couldn’t be happier. More DSP, More routing options and a great sounding conversion.

By Jason J on November 17, 2020

I upgraded from two older 8 QUADs and the x16 is amazing. Noticeably better converters, all in one 1U unit and all the benefits of the Apollo UAD system. Love it!

By Alex J on October 24, 2020

An amazing upgrade from MKII now I can really work with my outboard gear and hit the sweet spot without worrying about digital distortion thanks to the 24 DB Operation. I love it so much that decided to upgrade my Apollo 8p as well.

By Alvaro T on July 25, 2019

I had the original Apollo 8 and Apollo 16 and these units sound better and have better functionality. In particular, the routing with Logic works easily and makes sense- Joe at Vintage King was helpful, smart and VERY easy to work with. I traded in my old units and got nearly $2000 in trade. Great deal, awesome interfaces and I will do a ton of business with Joe in the future.

Love this with all my heart!

It's a solid upgrade from my BLA modd'd silver-face duo unit and my blackface quad 8. Conversion is noticeably improved with what I call a "deeper soundstage" and added clarity in the upper mids. Planning on pairing with a new Mac mini, but even with current 7-year-old iMac it was a great buy. Especially with the VK trade-in deal. I don't know if I would've splashed out the case without that.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
