Product Description

The Universal Audio Apollo Twin Quad MKII, is a 2×6 Thunderbolt audio interface including high-end 24-bit/192kHz audio converters and four realtime onboard UAD DSP processors. The Twin Quad MKII is the newest addition to the Apollo Twin series, with four SHARC processors in total, delivering unparalleled processing power for studio-grade effects.

The dual premium Unison mic/line preamps and front-panel Hi-Z instrument input allow you to capture premium-quality vocal and instrument recordings with ease. Apollo Twin Quad MKII’s Unison technology produces warm, analog-type tones that retain the natural harmonics of your source material for optimal accuracy and audio quality. The Apollo Twin Quad MKII comes complete with the Analog Classics UAD plug-in bundle that features a wide range of effects such as EQs, compressors and more.

The Apollo Twin MKII QUAD Desktop Interface with Realtime UAD Processing from Universal Audio is a Thunderbolt audio interface capable of capturing your audio in up to 24-bit/192 kHz with real-time, low-latency UAD plug-in processing. Building upon the success of the original, the Twin MKII offers a ground-up redesign of the A/D and D/A converters, as well as increased dynamic range and ultra-low THD. Other enhancements include improved monitor functionality with Mute, Dim, Mono, and ALT speaker switching, as well as monitor remote controls and a built-in talkback mic for easy communication with talent and/or recording slate cues.

Like the original, the Twin MKII features Universal Audio’s Unison technology, which, in conjunction with their UAD plug-ins, is capable of emulating a range of tube and solid-state microphone preamps, including their impedance and gain-stage sweet spots. The interface includes the Realtime Analog Classics UAD plug-in bundle, featuring legacy editions of the LA-2A Classic Audio Leveler, the 1176LN Limiting Amplifier, and Pultec EQP-1A Program Equalizer, plus Softube Amp Room Essentials, and the 610-B Tube Preamp.
