High-resolution UAD-2 Duo DSP audio interface with a classic analog sound.

View all items from this brand

The Apollo APD-DI from Universal Audio is a professional, high-resolution Duo DSP computer audio interface that delivers the sound, feel, and flow of analog recording. This 18x24 FireWire/Thunderbolt-ready interface combines genuine UA analog design with class-leading 24-bit/192kHz sound quality and onboard Realtime UAD Processing. Using the Apollo interface, you can have the ability to track audio through a range of available classic UAD analog emulation plug-in, from top-end recording companies such as Neve, Studer, Manley, Lexicon and more (sold separately). All of this processing is done in real time, and with a sleek elegant workflow on both Mac and PC environments.

24-bit/192 kHz Sound Quality for Pro Tools, Logic, Cubase & More
Apollo builds upon decades of UA’s analog design heritage as an extremely well-built, high-resolution audio interface, featuring premium mic preamps and top-end converters for low THD and high dynamic range. Its Core Audio and ASIO drivers ensure compatibility with all major DAWs, including Pro Tools, Logic Pro, Cubase, Live, and more. Moreover, Apollo’s included Console application and companion Console Recall plug-in (VST/AU/RTAS) provides control and recall of all interface and UAD plug-in settings within individual DAW sessions, even months and years later.

Realtime UAD Plug-In Processing for Tracking, Mixing and Mastering
Apollo differentiates itself from other interfaces with its Realtime UAD Processing. Available with either DUO Core or QUAD Core processing onboard, this DSP Acceleration allows for recording and mixing through UAD Powered Plug-Ins — with as low as sub-2ms latency — so that you can quickly monitor, audition, and “print” audio using additional classic analog emulations that are available from Ampex, Lexicon, Manley, Neve, Roland, SSL, Studer, and more. In this way, Apollo’s sonic character and tonal options are nearly endless. The onboard UAD processing also frees up host computer CPU for other virtual instrument or mixing duties.

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, and MacBook Airs. Available via a user-installable 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.

Attention Windows Users:
UAD Version 6.4 now with Windows 7 Support for 64-bit plug-ins, UAD-2 Satellite and Apollo Interfaces -- requires Windows 7 64-Bit and qualified PCIe-to-FireWire adapter.
