DIGITAL AUDIO CONNECTIONS
All versions of the RT-20 offer digital audio output on S/PDIF coax-
ial and S/PDIF optical connectors. The AES/EBU connector offers
S/PDIF digital audio output with AES/EBU electrical characteristics.
When making S/PDIF coaxial connections, use a 75ohm intercon-
nect cable with RCA plugs on each end. Make sure the cable plug is
fully inserted for a solid connection. When making S/PDIF optical
connections, use an interconnect cable with TosLink® plugs on
each end. As these cable plugs are keyed, it is important to insert
them with the proper orientation to the connector. Make sure the
cable plug is properly aligned with the connector before the cable
plug is inserted. When the cable plug is inserted, the protective
shutter on the connector will open and the plug will click into posi-
tion, indicating that the cable plug is fully inserted.
ANALOG AUDIO CONNECTIONS
All versions of the RT-20 offer analog audio output on eight RCA
connectors labeled Front L/R (2 pairs), Surround L/R, Center, and
Sub. When making these connections, use standard audio cables
with RCA plugs on each end. The Audio Out parameter can be
used to configure these connectors to provide 2-channel or
5.1-channel analog audio output. The analog audio output con-
nectors are color-coded to match the cable plugs. Make sure the
cable plugs are fully inserted for a solid connection.
DVD-A & SACD CONNECTIONS
An analog audio output connection is required for SACD and rec-
ommended for DVD-A playback. If your pre-amplifier has 5.1-chan-
nel analog outputs, connect them to the Front L/R (labeled Front
1), Surround L/R, Center, and Sub analog outputs. If your
pre-amplifier has only stereo inputs, connect them to the Front L/R
output pair labeled Front 1 or Front 2. When DVD-A sources are
sent to the digital audio output connectors, multi-channel signals
are downmixed and high sample rates of 176.4 or 192kHz are
downsampled to 44.1kHz or 48kHz.
