The UAD-2 Satellite Thunderbolt - OCTO Ultimate 4 from Universal Audio consists of a fan-less Thunderbolt 2 external enclosure with eight SHARC processors for use in Thunderbolt-equipped, Mac-based native audio workstations. The accelerator supplements the DSP processing of these systems, giving the computer's CPU more headroom and freeing resources for other functions that can include additional tracks, heavier mix automation, or the ability to use more native effects.
The Ultimate 4 version provides all of the company's in-house developed plug-ins, a library featuring 83 items co-developed with some of the best-known audio companies and products. These include some classic items that are no longer in production but have gained must-have status, tape machine emulations, and a host of audio processors, both vintage and modern.
The UAD-2 Satellite Thunderbolt supports the use of other manufacturers' Audio Units, AAX 64, RTAS or VST plug-ins when used with the appropriate host software. Additionally, up to four UAD-2 cards can be used simultaneously in a single host computer, or combined with other UAD-2 devices, including the UAD-2 Satellite, and Apollo audio interfaces.
