Prism AD2 - Audio A/D Converter

The Prism Dream AD-2 is a premium music A/D converter that provides an audio stream of exceptional quality. The AD-2 offers multi-rate A/D conversion for the most exacting applications in sound recording, mastering and broadcast.

The AD-2 is like two separate A/D converters, plus a digital processor, all in one: it can generate two entirely separate output signals simultaneously. These can have different sampling rates, different word-lengths - even use different noise-shapers. For example, you can output a 96kHz / 24-bit signal and a 44.1kHz / 16-bit noise-shaped signal at the same time. 

Apart from its breathtaking performance, the analogue front-end of the AD-2 includes many new features: Analogue input sensitivity (and inter-channel balance) is software-programmable over the entire range with 0.05dB resolution. Just as with the AD-1, the inputs are transformerless, electronically balanced and galvanically isolated (fully floating), to ensure freedom from noise pick-up and crosstalk. 

Digital to Digital Sample Rate Conversion
The 'D-D' (digital-to-digital) path, first provided in the AD-1, has been improved still further in the AD-2: It still offers re-dithering, noise-shaping and DRE encoding / decoding, but now it has synchronous sample-rate-conversion (SRC) as well. So you can re-process your 96kHz, 24-bit masters to 44.1kHz 16-bit streams for CD, or you can up-sample low-rate recordings for post-processing at a higher rate... in fact, you can convert between any two standard sampling-rates - synchronously. Synchronous sample-rate-conversion, if correctly performed, is free of the distortion artifacts associated with conventional 'variable-rate' SRCs. 

Dynamic Range Enhancement
The popular DRE function is retained from the AD-1: this allows you to make 24-bit quality recordings on 16-bit recorders such a DAT. DRE (Dynamic Range Enhanced) recordings need to be decoded on playback; the decode function is provided as an option in the 'D-D' mode. DRE, unlike conventional dynamic-range processing does not compress or add HF noise.
