Because partyline intercom does not have global level control on a channel, input
and output level controls are provided via the front panel programming. Scroll to
PORTS on the main display screen and press the rotary encoder to select. Scroll
to PLCHA or PLCHB and press to select. Select LEVELS, then select the input or
output level. This notation is relative to the Base station–input level refers to the
level at which everyone else hears the partyline, and output level refers to the
level at which the users on the partyline channel hear everyone else. Use the
rotary encoder to adjust the numerical level—clockwise to increase the level and
counter-clockwise to decrease the level.

4.2.5.1
Reducing FS II beltpack echo when talking to a analogue
partyline
partyline
If the Base station and beltpack are not set up correctly the FS II user will
experience an echo when talking to a partyline (either directly or via a group or a
wireless partyline). The echo is caused by either local audio coupling in the
headset due to the microphone gain being set too high or audio reflections from
the partyline that can be minimized by setting a VOX gate on the partyline and
the partyline being auto nulled. An FS II system has a built-in microphone gain
control, but a VOX gate level can also be set in the configuration editor (see next
section).

Include the partyline channel inside a wireless partyline
group
group
It is recommended that when connecting to an analogue partyline system that the
user includes the wireless partylines (WPL). The WPLs reduce the variation in
audio levels heard when talking to analogue partylines. The WPLs are created in
the configuration editor in a similar way to a user creating a group.
