IEC Power Receptacle — Connect a standard IEC AC power cord here for power
input
(100 VAC to 240 VAC, 50-60 Hz) to the internal, autoswitching power supply. This
connector may be replaced by the Flexible Conduit Adapter Kit (see Flexible Conduit
Adapter Kit Installation on page 16).
Mic/Line Inputs — Connect up to four 3-pole 3.5 mm captive screw connectors to
input up to four balanced or unbalanced line level or microphone level signals.
