Universal Audio Apollo Twin SOLO — Thunderbolt Audio Interface (UAD-2 Solo Core)

Universal Audio Apollo Twin Solo for sale — a legendary, professional-grade Thunderbolt audio interface that's been very well cared for. This is the Solo Core version (single UAD-2 DSP processor) with UA's renowned Unison mic preamps and onboard processing.

Condition: Excellent. Very minimal cosmetic wear — this unit was kept in great shape and barely shows its age. Fully functional, everything works as it should.

Specs / features:

• 2x4 Thunderbolt audio interface, 24-bit / 192kHz
• Two Unison-enabled mic/line preamps with the legendary UA sound
• Onboard UAD-2 SOLO Core DSP for real-time plugin processing
• Hi-Z instrument input, optical input, monitor and line outputs
• Class-leading conversion and preamps in a compact desktop unit

Includes:

• The Apollo Twin Solo unit
• Original box
• Thunderbolt-to-USB-C adapter included ($50 value) - cable is (approx. 2 ft) plus the adapter (~6 in), giving roughly 2.5 ft of total reach. Note this is on the shorter side — standard for Thunderbolt cables, so if you need more distance between your computer and the interface, a longer Thunderbolt cable is an inexpensive, easy add. Everything needed to connect to a USB-C Mac is included.

Note on compatibility: This is the original Thunderbolt-connection generation. It works beautifully on compatible Mac setups — just confirm your machine's Thunderbolt situation before purchase. On the newest Apple Silicon Macs it may require enabling kernel extensions; on most setups it's plug-and-play. Happy to answer any compatibility questions.

A genuinely great-sounding interface for anyone who wants UA's preamps and conversion at a fraction of new-unit cost. I'm only selling because I'm downsizing my studio setup.
