A CD or SACD player brings both digital and analogue domains into an audio system. For the very highest quality sound every part of the player is critical. A high-quality D/A converter alone is no longer enough. The 746 unites a top quality optical drive, a super-precise master clock generator, an intelligent digital signal processor with oversampling, and analogue output stages of the utmost quality. Together they ensure nothing in the music is lost on its way from disc to output connection.
As with its Series 7 sibling the 560 D/A-Converter is packed with cutting-edge technology with one objective – the love of music. The parallels include a consistent dual mono design in the output stages and separate power supplies for digital electronics and the analogue stages. The 560 D/A-Converter adds a digital volume control that allows direct connection to a power amplifier.
Burr-Brown devices perform D/A conversion only. Their internal upsampling and filter stages are not used. The output currents are converted to voltage and then filtered. With an internal bandwidth of 40 MHz, this current/voltage conversion stage allows best signal-to-noise performance and maximum dynamics in the analogue domain.
