MPACT 2
Mpact-2 is a 125 MHz vector-processing graphics, audio and video media processor, a second generation in the Mpact family of Chromatic Research media processors, which can be used only as a co-processor to the main Central Processing Unit of a microcomputer.
Hardware using the Mpact-2 uses OEM firmware to provide plug-and-play facility, and may be used with either a PCI or AGP bus.The UAD-1 was a digital signal processor card using the Mpact-2 sold by Universal Audio, which uses the DSP, rather than the host computer's CPU, to process audio plug-ins. This allows accurate, but processor-intensive, reverbs, EQs, compressors and limiters to be handled in real time and without burdening the CPU. 3D functionality is hard-wired. The UAD-1 was superseded by the UAD-2, based on the Analog Devices 21369 and 21469 DSPs, in 2007.
UAD-1 hardware was produced with three interfaces: PCI, PCI Express, and ExpressCard. The cards were offered by Chromatic Research, and were part of the Chromatic Mpact 2 Video Adapter.
