9.3.
ASL WIRELESS CONNECTED TO A PARTY LINE INTERCOM SYSTEM
9.3.1 Base Station Settings
a. Give each TX/RX module in the base
station its own TX/RX channel by rotating
the „Channel select‟ switch.
Try to avoid TX/RX channels to be
physically next to each other, e.g. when
two WS-
400‟s are in your wireless system,
try to set them in this order: TX/RX
channels 2, 4, 6, 8, 1, 3, 5, 7. If one uses a
WS-200 with only two beltpacks, use
TX/RX channels 1 and 6
b. Make sure the interface mode switch at the
rear of the base station is set to “PARTY
LINE”.
c. Connect the party line intercom system via
the XLR-3 connectors at the rear panel of
the base station. Each XLR-3 male and
female pair may connect each TX/RX
module to a channel of the party line
intercom system (see also section 9.3.3).
Everywhere this connection is made, the
internal party line is interrupted.
d. Turn down the side tone trimmers (counter
clockwise).
9.3.2 Wireless Beltpack Settings
e. With the Channel Select switch at the rear
of the beltpack, select the TX/RX channel
according to the WS-200 or WS-400
setting.
f. Connect a headset to the beltpack and
insert fully charged batteries. When the
beltpack is switched on, a single short tone
should be heard and both LED‟s on the
front panel of the unit flash for half a
second. This indicates that the beltpack is
functioning properly.
g. When one pushes the CALL or TALK
button, the LED‟s
on the front panel are lit
and the green LED of corresponding
TX/RX module of the base station is lit. It
proofs the beltpack has connection with
the base station.
h. Turn down the OWN VOICE Volume
trimmer at the side panel of the beltpack
(counter-clockwise)
i. Set the volume control of the beltpack at
approximately 50%
j. Push the TALK button on the beltpack, talk
into the microphone and listen to your own
voice (you might hear a small delay in the
signal)
k. Adjust the side tone trimmer of the
referring TX/RX module in the base station
so that the level of your own voice is as low
as possible
l. Adjust the OWN VOICE trimmer on the
beltpack so that the level of your own voice
is to your liking

9.3.3 Wiring configurations when connecting to a party line intercom system
Connecting to party lines can be done in many different ways. Below a few examples:
Example 1

When two WS-400 base stations are installed
and 8x WS-19 beltpacks are available:
The drawing shows how to connect all WS-19
beltpacks to the same party line.
