Further details on the UA Audio Apollo

The UA Audio Apollo Duo Core 18 x 24 FireWire/Thunderbolt- ready interface combines genuine UA analog design with class-leading 24-bit/192 kHz sound quality and onboard Realtime UAD Processing. Using Apollo, music producers and performers can finally track audio through a range of classic UAD analog emulation plug-ins — from Neve, Studer, Manley, Lexicon and more — in real time, and with a sleek, elegant workflow on both Mac and PC.

Class-Leading 24-bit/192 kHz Sound Quality
Designed to play a central role in a modern Mac- or PC-based studio, Apollo incorporates a true “no compromise” approach to audio quality. Building upon decades of UA’s analog hardware heritage, it offers extremely high-resolution sonics, with the lowest THD and highest dynamic range in its class. Apollo’s premium mic preamps, top-end converters — and UA’s meticulous attention to circuit design — translate into greater accuracy and depth in your recordings, from tracking and overdubbing, to mixing and mastering.

Realtime UAD Plug-In Processing for Tracking, Mixing and Mastering
While Apollo’s “natural” sound is exceedingly open and transparent, it can quickly deliver a wide range of classic analog tones and color via its Realtime UAD Processing. Available with either DUO Core or QUAD Core processing onboard, this onboard DSP Acceleration allows for recording and mixing through UAD Powered Plug-Ins — with as low as sub-2ms latency — so that producers can quickly monitor, audition, and “print” audio using classic analog emulations from Ampex, Lexicon, Manley, Neve, Roland, SSL, Studer, and more.
Want to place multiple 1176 compressors on your drum inputs, or record vocals through a classic Neve 1073 EQ, or even track the entire band through a Studer A800 tape machine in real time? No problem. With Realtime UAD processing, Apollo’s sonic options are virtually endless.

Thunderbolt™ I/O: The Next Generation of Connectivity
Apollo offers compatibility with Intel’s new Thunderbolt technology, as found on the newest iMacs, MacBook Pros, MacBook Airs, and next-generation PCs. Available via a user-installable dual-port Thunderbolt I/O Option Card (sold separately), Thunderbolt provides lower latency, reduced audio buffer size, improved performance, and greater UAD plug-in instances versus FireWire. And because Thunderbolt offers many times the bandwith of FireWire, it allows music producers to connect numerous devices in series with the Apollo interface — including hard drives, processors, and additional computer monitors — all with fast, flawless performance.

Deeper Integration with Pro Tools, Logic, Cubase and more
Apollo’s Core Audio and ASIO drivers ensure compatibility with all major DAWs, including Pro Tools, Logic Pro, Cubase, Live, and more. Beyond this basic compatibility, Apollo’s included Console application and companion Console Recall plug-in (VST/AU/RTAS) provide control and recall of all interface and UAD plug-in settings within individual DAW sessions, even months and years later.

Elegant Hardware Design and Workflow
One key feature of Apollo isn’t really a “feature” at all. It’s the numerous design details that give you a fast, natural workflow — and better results. There are physical front-panel controls for all the most commonly used features, including Preamp and Monitor level knobs, channel selection, mic pad and low cut, phantom power, and even dual headphone outs with independent level control. Smart Hi-Z inputs on the front panel detect when you've connected your guitar or bass, and automatically enable hardware and software monitoring.

Sonically, Apollo's Mic inputs and Monitor outputs are digitally controlled analog, so you don't lose audio resolution when you adjust gain. High-resolution/high-contrast metering, derived from UA’s legendary 2192 interface, is designed to be viewable at nearly any angle. Finally, standalone operation means that you can use Apollo’s audio connections, and last-used DSP mixer settings, even without a computer connected.

    Comments about Universal Audio Apollo Duo Core 18 x 24 Firewire/Thunderbolt Audio Interface:

    Universal Audio's Apollo is one of the best options for users that want real-time UAD processing while tracking, mixing and mastering their project. The UAD processing is all built into the 18 x 24, firewire 800 based, audio interface. The Apollo also has a thunderbolt card available as an option. Sound quality is amazing even without the added color you can get from the many UAD analog emulations available which are what really make this unit shine. I would highly recommend this for someone that is currently using a similar sized interface but is looking for better quality than what their current interface can provide.
