Base Station Operation
Power
If you have followed the instructions in Section 4, “Initial
Equipment Set-Up”, you should now be ready to turn the base
station on.
Set the base station power switch to the on position, by push-
ing the top of the switch.The internal cooling fan will start im-
mediately and the LCD display and front panel indicator lights
will come on in five or six seconds.
Local Headset
Talk Button - Press to enable the audio path from the local
headset. The TALK/O.M. LED will turn green when audio
is enabled. A quick press and release latches on the button.
If the talk function is latched on, pressing the talk button
again will turn it off. If the local headset is not being used,
the talk button should be off. This keeps additional noise
out of the system.
Microphone Gain - Adjusts the headset’s microphone
gain. Adjust so the TALK/O.M. LED flashes from green
to red on loudest speech.
Volume - Adjust the volume to the headset by rotating the vol-
ume control as required for a comfortable listening volume.
Beltpack Connect
Select the audio paths from the base station’s four receivers that
you wish to enable. The corresponding LED above the select
button is on when the audio path is enabled. If a beltpack user
has their beltpack connect path off at the base, that user will no
longer hear their sidetone and their audio will not be passed to
anyone. The user will still be able to hear everyone. The selec-
tion is retained in non-volatile memory, so it will come up
where last left if the unit is power cycled.
Always disable unused audio receive paths. This reduces the
chances that external RF noise can get onto the audio buses
via an open receiver.
Intercom
Intercom Select Button - Press the [SELECT] button to
choose between 2-wire or 4-wire intercom systems. The
green LED will indicate the current mode of the intercom
channel. If the base station is connected to a 2-wire sys-
tem, such as Audiocom (Telex), RTS TW or Clear-Com,
set the intercom to 2-wire. If it is connected to a
four-wire system, such as Matrix type system, set the in-
tercom to 4-wire. The selection is retained in non-volatile
memory, so it will come up where last left if the unit is
power cycled.
In Level Control - Adjusts the audio level of the wired
intercom system’s input to the base station.
Out Level Control - Adjusts the audio level of the base
station’s output to the wired intercom system.
If the base station is used stand-alone with no wired intercom
system connected, it must be set in the 4-wire mode. The
2-wire mode requires that a wired intercom system or appro-
priate load be connected to the intercom. If not loaded, a large
gain increase will take place in the unload intercom channel
which may be high enough to produce a loud “howling”
sound.
Auxiliary
Auxiliary Input Select Button - Press the [SELECT]
button to turn on or off the auxiliary input to the base sta-
tion. The selection is retained in non-volatile memory, so
it will come-up where last left if the unit is power cycled.
In Level Control - Adjusts the audio level of the wired
auxiliary system’s input to the base station.
Out Level Control - Adjusts the audio level of the base
station’s output to the auxiliary XLR plug.
The auxiliary output is always available at the back-panel out-
put XLR. It cannot be switch on or off like the input. Both the
input and output are balanced audio ports. Auxiliary input and
output audio is global. See Section 4 for more details.
