12 RC-5 In
The Master Reference Subwoofer is equipped with an RC-5 input that makes
custom installation easy and secure by accepting baseband RC-5 input commands
from hardwired remote controllers. The RC-5 input can be used, for example, when
the subwoofer’s IR sensor (5) is obscured from direct view.
13 RS-232
The Master Reference Subwoofer is equipped with an RS-232 port, which receives
messages from a computer-based control system, providing integrated control of
all subwoofer functions. See RS-232, on page 46, and the RS-232 Port: Sending
Commands and Interpreting Data developer’s reference for more information.
Notes
The 12 VDC output current is limited to 30 ma.
If the subwoofer is powered on via the 12 V trigger and the signal is active, the front panel
power button (1) or RS-232 cannot power it off. You must use the 12 V trigger.
