Party Line Channel A Connectors
The CellCom 10 base station 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 10, allowing
communication between the wired party-line equipment and CellCom 10
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 you can continue
the connection to another CellCom 10 base station 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 base’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 base station 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 shares a time slot with the stage announce output, described below.
Stage Announce Output Connector
This male 3-pin XLR connector allows a line-level audio signal, typically a voice
from a wireless beltpack user, 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. One beltpack at a time can access this output, and it must be
programmed to a CEL-BP. It is activated by pushing the talk on the beltpack
rotary encoder to which the SA Output is assigned.
Stage Announce Relay
This DB-9 male connector provides a relay closure that is triggered
simultaneously with the SA Output. The relay may be used to open an audio
pathway for the signal from the SA Output, or could also be used to activate a
light or lock or some other device. The relay may be wired for normally closed or
normally open operation, and the signal appears on pins 1 & 6 or 2 & 6. It is
rated to a maximum of 30-VDC at 1 amp.
