(Anyone wanting to build this kind of monster, however, should make sure that their computer's power supply is up to the job of supplying each card with enough power - some offвЂ“theвЂ“shelf PCs are very under-specified in this department, and the UAD hardware won't run reliably if it's starved of power.) Up to four UAD1 and four UAD2 cards can run simulataneously on the same computer, a setup that offers a trouserвЂ“trembling 44 times the processing power of a single UAD1 card. These are blessed with one, two, and four of Analog Devices' SHARC 21369 DSP chips respectively, each of which offers approximately 2.5 times the processing power of the Mpact 2. Three versions of the UAD2 hardware exist: Solo, Duo, and Quad. However, unable to source a more powerful codeвЂ“compatible replacement for Chromatic's Mpact 2 Media Processor chip (on which the UAD1 was based) they had to go back to the drawing board and design their new UAD2 around another signal processor, a step which inevitably lengthened the development process such that the secondвЂ“generation hardware has only now begun shipping.

This must partly be on account of the company's many painstaking digital recreations of classic analogue processors (including some of their own hardware range), which have been very successful in translating Universal Audio's enviable reputation for sonic excellence into the computerвЂ“studio world.Д«ut you can never have enough plugвЂ“in power, of course, so even since 2004 Universal Audio have been beavering away to give the concept a shot in the arm. So is the UAD2 everything we hoped it would be?Д®ver since we reviewed Universal Audio's firstвЂ“generation plugвЂ“in DSP PCI card, the UAD1, back in the October 2001 edition of SOS, more and more musicians have invested in the platform. It's been a long time coming, but the successor to Universal Audio's hugely popular UAD1 DSP card is finally with us.
