SPDIF Input
SPDIF IN can operate at 44.1 KHz, 48 KHz, 88.2 KHz or 96 KHz, and implements internal Jack
Sensing.
A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to
directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs.
Advanced features such as record-slot-select and SPDIF_IN routing to the DAC allow for simulta-
neous record and play.
Analog Mixer
An analog mixer is available on the 92HD73E. The mixer supports independent gain (-34.5 to
+12dB in 1.5dB steps) on each input as well as independent mutes on each input. A master volume
follows mixing and provides gain from -46.5dB to 0dB in 1.5dB steps.
