The Apollo DUO Core from Universal Audio is an18 x 24 FireWire/Thunderbolt- ready computer audio interface that delivers the sound, feel and flow of analog recording. The interface combines high-resolution analog design with onboard UAD Processing, allowing music producers and performers to track audio through a range of classic UAD analog emulation plug-ins in real-time.
Designed to perform a central role in a modern Mac or Window based studio, the unit delivers 24-bit/192kHz resolution which ultimately translates into high-resolution analog audio, with low THD and high dynamic range. The interface features four premium microphone preamps with switchable phantom power, 20dB pad, polarity inversion, and stereo link.
While the converters are open and transparent, the unit can quickly deliver a wide range of classic analog tones and color via its built-in UAD Processing. The onboard DUO Core processing provides up to a sub-2 millisecond latency that allows for quickly monitoring, auditioning, and "printing" audio using classic analog emulations from Ampex, Lexicon, Manley, Neve, Roland, SSL, Studer, and more.
Apollo's Core Audio and ASIO drivers ensure compatibility with all major DAWs, including Pro Tools, Logic Pro, Cubase, Live, and more. The included Console application and companion Console Recall plug-in provide control and recall of all interface and UAD plug-in settings within the individual DAW sessions, for exact recall months or even years later.
Lower latency, reduced audio buffer size, improved performance, and greater UAD plug-in instances versus FireWire are all available via a user-installable, dual-port Thunderbolt I/O Option Card (sold separately). And because Thunderbolt offers many times the bandwidth of FireWire, it allows for connecting numerous devices in series with the Apollo interface, including hard drives, processors, and additional computer monitors.
