IEC Power Connector
The 3-conductor AC power connector and universal power supply
accepts voltages from 90 to 250 volts, at 50/60 Hz. Power
consumption is 80 watts.
Party Line Channel A Connectors
The CellCom basestation provides two pairs of party-line connectors,
labeled “Channel A” and “Channel B.” Each pair of female and male
3-pin XLR connectors joins a channel of party-line intercom to the
CellCom, allowing communication between the wired party-line
equipment and CellCom wireless beltpacks. Input and Output level
control is set via the front-panel display programming.
The second connector of each pair is a loop-through, so that the user
can continue the connection to another CellCom basestation or to
another party-line beltpack or station. This connector auto-detects a
connection with a powered party-line channel (30-VDC on Pin 2), and
the basestations’s internal 200-ohm party-line termination and DC
voltage to power PL beltpacks is not activated.
Alternatively, when a wired, unpowered party-line beltpack (up to four)
is connected to PL CH-A with standard two-conductor shielded
microphone cable, the basestation engages the 200-ohm termination
and supplies 24-VDC to the beltpack(s) – allowing them to operate and
communicate with the wireless beltpacks in the system.
Party Line Channel B Connectors
These connectors are the same as those for PL CH-A.
Program Input Connector
This female 3-pin XLR connector accepts a line-level audio signal from
an outside source such as a mixing console or audio player. It is
transformer-isolated. Level adjustment is done via the front-panel
display programming. The program input can be assigned as an IFB
source from the front panel.
Stage Announce Output Connector
This male 3-pin XLR connector allows a line-level audio signal,
typically from wireless beltpacks or 4-Wire sources, to be sent to a
paging system or other audio system. It is transformer-isolated. Level
adjustment is done via the front-panel display programming. More
than one audio source at a time can be routed to the Stage Announce,
with the audio being combined to give a single audio output.
