The original Apollo, introduced in 2012, quickly became a gold standard among modern music producers and engineers - it now counts many of the world's top artists as users. Apollo 8 improves upon the original Apollo's sound quality with completely redesigned, class-leading A/D and D/A conversion - giving you increased dynamic range and even lower THD. Building upon a 50-year legacy of circuit design, UA engineers started with an obsessive audition of the latest converters, pairing them with completely redesigned analog circuitry. Confirmed by extensive double-blind listening tests, the end result is 3 dB better dynamic range on both A/D and D/A conversion versus the original Apollo, placing the Apollo 8 as the measurable class leader. Realtime UAD Plug-In Processing for Tracking, Mixing and Mastering. Imagine having a classic analog studio, in single rack space. Apollo 8 lets you record through UAD Powered Plug-Ins - including vintage EQs, compressors, reverbs, tape machines and more - at near-zero latency, regardless of your audio software buffer size. With award-winning UAD plug-ins from Ampex, Lexicon, Neve, Manley, Roland, SSL, Studer and more, Apollo 8 serves up authentic analog tone and warmth. The key to its analog sound is onboard UAD-2 DUO or QUAD DSP Processing, which powers the UAD plug-ins while reducing the strain on your host computer. Apollo 8 comes bundled with Realtime Analog Classics Plus suite of UAD plug-ins. From there, you can choose from a vast and expanding collection of plug-ins in the UA Online Store. Four Mic Preamps with Unison Technology. Apollo 8 comes equipped with four Unison-enabled mic preamps, letting you track projects with colorful mic preamp sounds from Neve, API and Universal Audio. An Apollo breakthrough, Unison technology nails the tone of these sought-after tube and solid state mic preamps - including their impedance, gain stage sweet spots, and component-level circuit behaviors. The secret to Unison is its hardware-software integration between Apollo's mic preamps and its onboard UAD-2 processing. Simply place a selected tube or solid state preamp plug-in on your desired mic input and record in real time through stunning emulations like the bundled UA 610-B Tube Preamp plug-in or the Neve 1073 and API 212L. Impedance and Gain Matching. Apollo 8 is further enhanced by adding Unison technology to its front-panel Hi-Z instrument inputs, giving you dead-on impedance and gain matching for new stompbox models like the Ibanez Tube Screamer TS808. Improved Monitoring and Workflow. Apollo 8 features a host of front-panel upgrades over the original Apollo, including Alt Speakers, Dim and Mono functions as well as input and output metering capabilities. Expand Your System. Thanks to Apollo Expanded software, users of Thunderbolt-equipped Apollo Twin, Apollo 8, Apollo 8p and Apollo 16 audio interfaces can combine up to four Apollos and six total UAD-2 devices - adding I/O and DSP as your studio grows. Apollo Expanded also provides seamless integration with previous generation Apollos over Thunderbolt.
