Last updated on May 27, 2024 10:23 pm Details


In this review post, we’re going to be discussing the Universal Audio Apollo Twin MKII, including an overview of its unique features.

Product Description

Apollo Twin MkII is a ground-up redesign of the world’s most popular professional desktop recording interface for Mac and Windows — delivering enhanced audio conversion with the tone, feel, and flow of analog recording.

Built upon UA’s 60-year heritage of audio craftsmanship, Apollo Twin MkII starts with two Unison™-enabled mic preamps and stellar next-generation A/D and D/A conversion derived from UA’s flagship Apollo 8, 8p, and 16. Together with its included bundle of UAD analog emulation plug-ins — which you can track through in real-time with UAD-2 DUO Core processing — and access to LUNA Recording System, Apollo Twin MkII is born to make records.

Apollo Twin MkII features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, SSL, API, Manley, and Universal Audio. An Apollo exclusive, Unison technology nails the tone of this sought-after tube and solid state mic pres — including their input impedance, gain stage “sweet spots,” and the component-level circuit behaviors of the original hardware.

The secret to Unison is its hardware-software integration between Apollo’s mic preamps and its onboard UAD-2 DUO Core DSP Acceleration. Simply place a Unison preamp plug-in on your mic input, and tap into the classic sounds of the world’s most recorded mic preamps.

Our Verdict

The Apollo Twin MkII performs more than just connecting with Unison preamps and complete access to the UAD repertoire. The Universal Audio Apollo Twin MkII audio interface is one of the best you’ll ever use. However, because it is in a tough price bracket, it remains a problematic purchase for some people. It’s certainly worth the money, but it’s also way out of reach for the typical beginner.

If you can afford the investment, it’s the best there is. Everything about it is fantastic, from the Unison preamps to the strong DSP to the plugin bundle.

Where to Buy

The best place to buy this product has to be Amazon, due to their competitive pricing and fantastic customer service.
