Configuration example #3
REMOTE 1 can be a Bose volume control with A/B switch user interface accessory (PC 041967) and
REMOTE 2 can be a volume control user interface accessory (PC 041966). In this configuration, REMOTE 1
controls the level of output one and the source selection for both outputs. REMOTE 2 controls the level
for output two. The A/B pin from REMOTE 1 needs to be jumpered with wire to the A/B pin on REMOTE 2.
This configuration requires setting the REMOTE 1 CONTROL DIP switch to ZONE 1 and the A/B SELECT
DIP switch to REMOTE. If the A/B jumper wire is not connected, output two will default to amplifying
input B constantly. If output two is to amplify input A constantly, the A/B pin of REMOTE 2 needs to be
jumpered to the COM pin. This configuration also works with the remote types reversed with a volume
control user interface accessory (PC 041966) on REMOTE 1 and a volume control with A/B switch user
interface accessory (PC 041967) on REMOTE 2.
