Power Options
RemoteAmp Three was designed to be compatible
with most 3 pin XLR party line intercom systems
such as ClearCom®, RTS™ TW or Audiocom® or
other similar intercom systems. Many of these inter-
com systems provide power on either pin 2 or pin 3
of the XLR jack that can be used to operate a per-
sonal beltpack unit.
RemoteAmp Three has an internal jumper that can
be configured so this beltpack device can take ad-
vantage of that power when it is available. This unit
will draw power from a 9 V battery if power from the
intercom system is not available or is insufficient.
Please refer to the specifications for your intercom
system to determine where to set the jumper in the
RemoteAmp Three. Placing the jumper across J3
will draw power from Pin 3 of the XLR jack. Placing
the jumper across J5 will draw power from Pin 2 of
the XLR. Removing the jumper entirely will force the
RemoteAmp Three to draw power only from the 9V
battery.
