A1240
INSTALLATION MANUAL
The term BUS is defi ned as the ability to route a signal
from one place to another. Traditional busing is done
using audio patch cables to route these signals. The use
of Bus Switches, such as the ones on the A1240, elimi-
nates the need for additional patch cables and adds to
the fl exibility of signal routing.
Bus Input & Bus Loop Ouput
A stereo or monaural audio signal connected to the
A1240’s main BUS INPUT can be routed to any of the
A1240’s twelve channels. This feature is excellent for
standalone distributed audio systems where one source
(i.e. an A/V Receiver) is providing audio to the entire
home, and also for ELAN multi-room applications where
a zone’s audio signal needs to be routed to multiple
amplifi er channels. Examples of both these applications
are shown on the following pages.
3. Bussing
The BUS LOOP OUTPUT is an easy way to add on ad-
ditional rooms of music by connecting them to a second
(or 3rd, or 4th) A1240.
Bus DIP Switch Settings
There are independent BUS DIP switches for each chan-
nel on the A1240. The DIP switches labeled BUS L (Left)
and BUS R (Right) determine whether the signal con-
nected to the Left and Right channels of the BUS INPUT
will be routed to that channel. Any channel that has its
BUS switches in the ON (DIP switch set to the left) posi-
tion will receive the audio signal from the BUS INPUT.
