About the Universal Audio Apollo Twin DUO MKII Thunderbolt Audio Interface
The Apollo Twin MkII DUO is a desktop Thunderbolt audio interface for Mac and Windows whose two SHARC DSP chips run UAD plug-ins on the interface rather than on the computer; it records at up to 24-bit/192 kHz. Inputs are two Unison mic/line preamps on combo XLR/TRS jacks, a front Hi-Z instrument input and an optical input for 8 more ADAT channels; outputs are two monitor and two line outputs on 1/4 inch jacks plus a headphone output. Unison plug-ins set the impedance and gain of the preamps and the Hi-Z input to match the modelled hardware. Against the first Apollo Twin, the MkII has redesigned converters, Mute, Dim, Mono and ALT speaker switching, and a built-in talkback mic.
The port is Thunderbolt 2, so a computer with Thunderbolt 3 on USB-C needs a Thunderbolt 3 to 2 adapter; Windows 10 PCs with built-in Thunderbolt 3 work since UAD software 9.0.0. Every unit comes with the Realtime Analog Classics bundle (legacy LA-2A, 1176LN and Pultec EQP-1A, the 610-B Tube Preamp, guitar and bass amp models), and LUNA, UA's recording application for Mac, is a free download. Plug-ins are registered to the unit in a Universal Audio account: on a sale the owner transfers the device and its plug-ins to the buyer's own account. Many used units carry extra plug-ins the previous owner bought, 13 to 23 titles in all; others come with none. The box holds a power supply with plug adapters for other countries, and used units often come with a Thunderbolt cable too.
