Next-Generation Audio Conversion with Classic Analog Sound and Solo Processing. 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 SOLO, DUO or QUAD Core processing — Apollo Twin MkII is born to make records. Record with world-class Apollo A/D and D/A conversion — as heard on hundreds of hit records Cascade up to 4 Apollo interfaces and 6 UAD-2 devices over Thunderbolt, adding DSP and I/O as your studio grows Mix with UAD plug-ins like the included Teletronix® LA-2A and 1176 compressors, Pultec® EQs, and 610-B Preamp Track with near-zero latency through preamp emulations from Neve®, API®, Manley® and more using Unison™ technology† Unison Technology: The Genuine Sound of Neve, SSL, API & Manley Preamps 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 these 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 QUAD or DUO Core DSP Acceleration. Simply place a Unison preamp plug-in on your mic input in Apollo Console software, and it physically reconfigures the Apollo interface's impedance — so you can tap into the classic sounds of the world’s most recorded mic preamps.
