output levels either at matrix side or within the CellCom front-panel
display for the particular CellCom 4-wire port.
CONNECTING WITH OTHER 4-WIRE DEVICES
Various other 4-wire audio devices can be connected with CellCom.
The Clear-Com EF-701M 4-wire interface can be used to attach
additional party-line channels to CellCom, converting them from
party-line on the wired side to 4-wire on the CellCom side.
The Clear-Com IF4W4 interface can be used similarly. The audio input
side of the CellCom 4-wire connectors could be used for additional
program or other audio inputs that could then be accessed by CellCom
beltpacks. The audio output side of the CellCom 4-wire connectors
could be used to route a CellCom wireless beltpack user’s voice out of
the system for paging or other reasons, similar to the SA OUT
connector.
When using the CellCom 4-wire ports in this way, make sure that
proper connections are made between CellCom and the other device.
Adjust the input and/or output levels either at the 4-wire device or
within the CellCom front-panel display for that particular 4-wire port.
CONNECTING TO A PROGRAM AUDIO
SOURCE
CellCom can connect with a program audio source, making it
accessible to be assigned by itself to a communication path to one or
more CEL-BP wireless beltpacks, or to be added to a group with other
communications and assigned to beltpacks. Using the two separate
rotary encoder volume controls on the beltpack, the user can monitor
the program on one control while talking and listening on an intercom
channel with the other.
The balanced female 3-pin XLR connector accepts a standard audio
signal from a mixing console or similar, with Pin 1 ground, Pin 2 audio
hot (+), and Pin 3 audio cold (-).This connector is transformer-isolated.
To make the program input signal available to the system, the
front-panel PRGM enable button must be activated/on. The red LED
above it will light, indicating that it is now available. This front-panel
switch may be “locked” to prevent accidental disengagement, using
the front panel display.
Using the front-panel display and rotary encoder, the user may select
PORTS and give the connector a five-character alphanumeric label.
The user may assign that program input by itself to a beltpack using
the BELTPACKS menu, or use the GROUPS menu to assign the
program input to any group or wireless party line. Program input can
be assigned to multiple groups or wireless party lines using the
GROUPS menu.
