Feature Description
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.
Partyline channel A connectors
The FS II Base station provides two pairs of partyline connectors, labeled
“Channel A” and “Channel B.” Each pair of female and male 3-pin XLR
connectors joins a channel of partyline intercom to the FS II, allowing
communication between the wired partyline equipment and FS II 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 FS II Base station or to another partyline
beltpack or station. This connector auto-detects a connection with a powered
partyline channel (30-VDC on Pin 2), and the Base station’s internal 200-
ohm partyline termination and DC voltage to power PL beltpacks is not
activated.
Alternatively, when a wired, unpowered partyline 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.

Program input.
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.
