3.3 Rear Inputs
At the rear of the AM-777, there are 4 sets of RCA inputs for the connection of source components such as the
CD-777 compact disk processor or a vinyl source. The XLR input is shared with the RCA Input 1. The fifth input
is USB only and can only be selected if connected to a Computer Audio Source.

LEFT channel (white) of Input 1: via XLR or RCA.

back. No software drivers are required under Windows XP SP2 or later and Mac OS X. Make sure the playback
application is set correctly to output sound to the ‘USB Audio Device’.
