NOTE: The input connector port may be labeled
one of two ways. The wiring and function
are the same, whichever way your product
is labeled.
NOTE: For mono input on the XPA 2001, because the left and right channels are
summed, only the left channel needs to be wired. No jumpering to the right
channel is needed.

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.
NOTE: The remote control port may be labeled one of two ways (see the
following images). The wiring and function are the same, whichever way
your product is labeled.
Pins V, C, and G (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 C is
connected to ground (pin G). Use the included 3-pin captive screw connector.
See “Remote Volume Control” on page 17.
