Intercom Switch
The Clear-Com
®
wireless system can be interfaced to
Clear-Com, RTS TW, Audiocom
®
(Telex), Matrix and other
intercom (I/C) systems. Set the Intercom switch on the rear of
the unit to the appropriate system and connect the system to
the base station. The intercom channel on the rear of the base
station has loop thru male and female XLR connections for
two-wire systems and a RJ-45 type jack for four-wire systems.
This switch only affects the two-wire intercom systems. The
functions of the I/C XLRs change depending on the intercom
selected. Please see Section 11 for pinout information of the
different two-wire intercom systems.
Auxiliary Input/Output
The input and output 3-pin auxiliary connections are for sup
-
plying additional balanced audio into and receiving balanced
audio from the base station. The input and output auxiliary
audio is global. This means the input and output auxiliary au
-
dio is placed on the base local headset, beltpack(s) headsets
and any wired intercom system interfaced to the base sta
-
tion.
Intercom Interface
Clear-Com
®
and Telex (Audiocom
®
) intercom systems require
one cable for intercom. This interfacing is done through the
I/C 3 pin XLR connectors on the rear of the unit.
RTS TW intercoms also only need to connect one 3-pin cable
to one of the two intercom XLR connectors. Two channels of
audio are carried on one cable for RTS. RTS channel 1 is
placed on the intercom normally. Switch the rear-panel I/C
switch to Clear-Com
®
to interface only to RTS audio channel
2. Once again, leave it in RTS to interface to only RTS audio
Channel 1.
Four wire intercom systems require only one cable for the in
-
tercom to interface four wire intercom to the base station. This
interfacing is done through the I/C RJ-45 type jacks on the
rear of the unit. See Figure 16 for the pinout of the RJ-45
jacks.
A modification document is available from Clear-Com for
those who wish to modify the base station so that auxiliary in
-
put audio is heard only locally; base local headset and
beltpack(s) headsets.
