12 RC-5 In

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.

His exploration of technologies, driven by his never-endingquest to elevate the standard of excellence, has resulted in break- through audio designs. Over the years, the Krell line of power amplifiers, including benchmark products such as the KRS -100,KRS -200,and the Audio Standard models, has established a legacy of unparalleled sonic performance.
