BaseStation Overview
Front Panel Left
1- Local Headset Connector
The 4-PIN XLR male headset connector is compatible with most Dynamic or Electret headsets that have 4-PIN XLR
female connectors. This headset connector allows a user to communicate on any one of the two intercom channels.
Controls for this connector are located to the immediate right. The mic gain for the Local Headset can be adjusted
from the “Set Mic Gain” menu, under the “BaseStation Settings.” (Note: the headset must be purchased separately.)
2- Talk Button and LED
The Talk button works in conjunction with the Local Headset Connector. The Talk button enables or disables the
microphone for the local headset. A blue “TALK” LED will illuminate when the mic is enabled. Tempest uses an
intelligent latching method for talk buttons. Pressing TALK momentarily will cause the mic button to latch. The blue
“TALK” LED will stay lit and the microphone will remain enabled. Pressing and holding TALK will cause the button to
act in a momentary fashion. The blue “TALK” LED will remain lit and the microphone will remain enabled only as long
as the button is pressed.
3- Call Button
The Call button sends a wired intercom-compatible call signal to any wireless BeltStation and any 2-Wire hardwired
intercom device on the intercom channel currently selected for the Local Headset.
4- Mic Kill Button
The Mic Kill button sends a signal to wireless BeltStations that disables Talk buttons that are enabled. This button is for
the wireless system only. No Mic Kill signal is sent out to the hardwired intercom. Mic Kill signals from the hardwired
intercom are accepted and passed through to the wireless users.
A momentary press and release of the MIC KILL disables any wireless BeltStation Talk button currently enabled on
the selected channel, as well as the BaseStation local headset connector. If the Mic Kill button is pressed and held
for three seconds, all wireless BeltStation Talk buttons on all channels are disabled. A wireless BeltStation user may
enable a Talk button at any time after the Mic Kill button is pressed and released. The “OFF” indicator appears in place
of the “TALK” indicator on the BeltStation display and the user will not hear sidetone if both Talk buttons are OFF.
5- Local Headset Channel LEDs
The two Local Headset Channel LEDs labeled A and B indicate the currently selected intercom channel for the
BaseStation local headset. Only one channel may be selected at a time. Pressing the Volume control while in
Operational Mode cycles the Channel LEDs in order from A to B.
6- Peak LEDs
The two PEAK LEDs indicate when the mic audio from the local headset is reaching a peak level and is about to
enter into limiting. These indicators should not be illuminated during normal use. The mic gain for the Local Headset
connector can be adjusted from the “Set Mic Gain” menu, under “BaseStation Settings.” Setting the mic gain correctly
is critical for quality communication audio.
