The Stereo Cleanfeed channel has one balanced
stereo input and a balanced stereo cleanfeed
input, on XLR connectors. The channel is
intended for use where a remote stereo source,
such as another studio connected via ISDN,
requires a stereo cleanfeed return. The cleanfeed
is generated by a separate stereo cleanfeed bus
which follows the PGM output routing matrix.
