CALLIA supports linear PCM in 2’s complement binary coding and, using the “DSD over PCM” (DOP) protocol, DSD at the original bit-rate (DSD64) and also at 2 x the original rate (DSD128). DSD Files encoded as “DOP” may be played with both ASIO and WDM drivers.

Your computer, tablet or transport will commonly decode formats such as mp3 to PCM prior to transmission to the sound card, so these formats will typically be supported on your device in the same manner as they would be with another sound card.

On the S/P-DIF inputs, DOP can also be used, but only at the original DSD bit rate (DSD64) as these connections do not have enough bandwidth for DSD128.

The ASIO native DSD format is not currently supported.
