UA's Apollo Twin X is a desktop 10x6 Thunderbolt 3 interface built around Unison-enabled mic preamps and onboard UAD SHARC processing (DUO or QUAD variants). Two combo XLR/TRS inputs and a dedicated front-panel 1/4-inch Hi-Z jack feed the preamps. Two balanced 1/4-inch monitor outputs and two 1/4-inch line outputs cover stereo monitoring plus an auxiliary pair, with a front TRS headphone out. An optical TOSLINK input carries ADAT or S/PDIF for eight channels of external expansion. Power comes from the included external supply — Thunderbolt bus power is not supported.
Universal Audio’s Thunderbolt 3 desktop interface with Unison preamps, combo XLR/TRS + front Hi-Z inputs, dual line-out pairs, ADAT in.
