LINE CONNECTIONS
Line In
Each zone has its own dedicated stereo LINE IN using two RCA jacks. Use a stereo RCA
audio cable (not included) to connect the LINE OUT of an audio source device (e.g., CD
player, FM tuner, etc.) to the individual zone LINE IN, as shown in the diagram below.
Bus Audio
The amplifier also features a stereo analog BUS
AUDIO IN (3), a digital S/PDIF OPTICAL IN (2),
and an analog BUS AUDIO OUT (4). The audio
on BUS AUDIO IN overrides the zone's LINE IN
(10) audio whenever a +3 ~ +30 VDC trigger
voltage is applied to LINE BUS TRIGGER IN (8).
BUS AUDIO IN (3) is a 3.5mm stereo analog
input. Use a stereo 3.5mm to RCA or 3.5mm to
3.5mm audio cable (not included) to connect
to a stereo line level or headphone level
source. Alternatively, use a digital optical
S/PDIF cable (not included) to connect the BUS
AUDIO OPTICAL IN (2) to the optical S/PDIF
output of an audio source device.
BUS AUDIO OUT (4) is a 3.5mm analog stereo
audio output that can be used to connect to
the input of another amplifier or audio processor. BUS AUDIO OUT (4) is a copy of BUS
