2 SPDIF outputs are provided,
RCA1
and
RCA2
, on RCA phono connectors (G). Each outputs the
same SPDIF data at the same sample rate that is present on the USB interface, if it is active. You can
use both outputs at the same time if you wish.

The
USB
interface on a ‘B’ type connector (H) accepts uncompressed PCM data up to 24 bits,
sampled at 32, 44.1, 48, 88.2 or 96kS/s from a Windows™ PC, Apple Mac™ or sound server
equipped with a USB 1.1 interface or later.

We have tested this interface with several common formats running on Windows™ Vista,
Windows™ XP and Apple Mac™ OSX but we cannot accept responsibility for correct
operation with all source devices, operating systems or software.
