The Universal Audio UAD-2 OTCO Thunderbolt is the most powerful DSP accelerator that UA makes and gives audio engineers and producers access to the brand's highly lauded library of analog modeling plugins as well as provides access to more than 90 plugins from other brands—including Ampex, Manley, Empirical Labs, and Roland just to name a few. A space-efficient and sleek desktop unit, the OCTO is compatible with all Thunderbolt-capable Mac computers, with Thunderbolt 2 tech promising lower plugin latency than FireWire 800.
