Universal Audio Apollo Solo USB Audio Interface – No Longer Available

Universal Audio's most compact desktop USB interface featuring two Unison preamps, UA's fantastic AD/DA conversion, world-class UAD processing and the Realtime Analog Classics software bundle

Product Description

With the launch of the Universal Audio Apollo Solo USB interface, the legacy of the Apollo line has been condensed to its smallest form and given a new level of connectivity. The 2x4 USB audio interface offers Windows users access to an interface with beautifully detailed Unison enabled mic pres, onboard DSP for recording and mixing with UAD plug-ins with near-zero latency and premium conversion.

Universal Audio’s Unison Microphone Preamps

The Apollo Solo comes standard with two Universal Audio Unison enabled mic preamps, allowing you to track with pristine sounding clarity and replicate the sounds of classic preamp sounds with UAD plug-ins. Track with the legendary sounds of Neve, API, Manley, and more with the click of a button and the Apollo Solo adjusts the impedance of the preamp to match the emulated hardware. A convenient Hi-Z input on the front panel allows you to go direct in seconds, and one knob control formatting allows you to dial in your gain with ease.

World-Class UAD Processing

Track and mix with classics like the 1176LN, LA-2A, Pultec EQs in real time! With onboard DSP, the Apollo Solo allows you to take advantage of the detailed, rich sounds of UAD plug-ins with near-zero latency. The Realtime Analog Classics bundle will get you to work in no time, featuring other legendary gear like the 610 preamp, the Ampeg SVT-VR, and the Marshall Plexi guitar amp emulation.

Ready To Record And Mix Anywhere

Whether you’re a musician on-the-go or just need something to track vocals and an instrument at home, this interface is perfect option for any aspiring recording artist. The Universal Audio Apollo Solo USB features a premium headphone amplifier for monitoring and is housed in heavy-duty metal casing that is road-ready.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

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.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
