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. 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.ĭigital to Digital Sample Rate Conversion For example, you can output a 96kHz / 24-bit signal and a 44.1kHz / 16-bit noise-shaped signal at the same time.Īpart 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. These can have different sampling rates, different word-lengths - even use different noise-shapers. 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. Clock stability, and rejection of incoming reference jitter are also improved. 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.Ĭonverter performance is pushed ever-nearer the limit: Dynamic range reaches a massive 130dB, THD+N at full scale is raised to 108dB (0.0005%). 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. The 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.
