Remote control connector — The 3.5 mm 5-pin captive screw
receptacle is used to remotely control two functions through
contact closure: See the following circuit diagram.
• Pins 1, 2, and 3 control volume by varying the DC voltage
from 0 V (full attenuation) to 10 V (maximum volume) with
full muting in effect when pin 2 is connected to ground (pin3).
Use the included 3-pin captive screw connector. See "Remote
volume control" in this chapter.
