Connecting Base Stations Together
Interconnection to a Hard-Wired Intercom
System
The Radiocom wireless system can be integrated
into Audiocom (Telex) intercom systems and most
existing wired intercom systems including RTS and
Clear-Com.
Connect the intercom cable to the back of the base
station. The intercom system may be connected to
the base station via the XLR, D-Sub, or Aux con-
nector in the rear of the unit. Audiocom, RTS and
Clear-Com intercom systems use either the XLR or
D-Sub connector. RTS Matrix intercom systems
typically use the Aux connector. Example configu-
rations of the two most popular intercom systems
are shown in Figures 29 and 30.
NOTE: It is not recommended to interface an inter-
com system thru the “Aux” jack while at the same
time having a different intercom system connected
to the XLR or D-Subs.
It is recommended that Clear-Com intercom sys-
tems be interfaced to the base station through the
use of CCB-1 Adapters. These adapters convert
Clear-Com intercom signals to Telex intercom sig-
nals and vise versa. See “Accessories” for more in-
formation.
