Vivaldi DAC uses the latest groundbreaking dCS technology including ‘next generation’ versions of the dCS Ring DAC™, Digital Processing Platform and Clocking System so that, as the hub of a digital audio system, an array of features guarantees superlative performance from any digital source.
Vivaldi DAC features standard AES3, Dual AES, SDIF-2 and S/PDIF inputs in addition to an asynchronous USB 2.0 interface. The enhanced digital volume control allows direct connection to a power amplifier so that in the majority of systems there is no need for a separate preamplifier. Maximum output can be set any one of four levels to suit different amplifier and speaker combinations.
