8 Channels Of 24-bit, A/D & D/A Conversion
The Prism Sound Dream AD-2 is the definitive music A/D converter, providing the most accurate rendition of an audio event whether it be early music, classical, jazz, big band, a club mix or hard rock. The AD-2 conversion system provides an audio stream of such exceptional quality that it will be relied upon for years to come as the definitive source for productions on CD, DVD, Super Audio CD or other formats as they become available. It offers a wealth of sophisticated features as well as high-performance, 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.
The four tried and tested Super-Noise-Shaping ('SNS') curves are extended to include optimal shaping for the higher sampling rates. The SNS process gives greatly-improved small-signal performance for limited word-lengths, such as CD, and is completely compatible with existing D/A converter products (including consumer and professional CD players).
The AD-2's front panel gives a clear indication of the main control settings at all times. Audio level is shown on 16-segment meters. A menu system allows control of operating parameters, and 16 stores are provided (including eight 'factory' modes) which can be recalled at the push of a button. A unique 'Setup Wizard' feature simplifies configuration of the AD-2 for new users.
The digital inputs and outputs of the AD-2 cover a wide range of formats. Digital outputs are available in all formats irrespective of the input format in use. When generating two different output signal paths, the AD-2's digital outputs can be freely assigned to either path.
Prism has been very busy since their first generation converters came out in 1994. Take a long look at the new AD-2 and DA-2 and you'll see why. They have compromised on nothing. These converters quite simply redefine the state-of-the-art.
