BaseStaon Overview
Front Panel Le
1- Local Headset Connector
The 4-PIN XLR male headset connector is compable 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 four 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 “BaseStaon Sengs.” (Note: the headset must be purchased separately.)
2- Talk Buon and LED
The Talk buon works in conjuncon with the Local Headset Connector. The Talk buon 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 buons. Pressing TALK momentarily will cause the mic buon to latch. The blue
“TALK” LED will stay lit and the microphone will remain enabled. Pressing and holding TALK will cause the buon to
act in a momentary fashion. The blue “TALK” LED will remain lit and the microphone will remain enabled only as long
as the buon is pressed.
3- Call Buon
The Call buon sends a wired intercom-compable call signal to any wireless BeltStaon and any 2-Wire hard wired
intercom device on the intercom channel currently selected for the Local Headset.
4- Mic Kill Buon
The Mic Kill buon sends a signal to wireless BeltStaons that disables Talk buons that are enabled. This buon is for
the wireless system only. No Mic Kill signal is sent out to the hard wired intercom. Mic Kill signals from the hard wired
intercom are accepted and passed through to the wireless users.
A momentary press and release of the MIC KILL disables any wireless BeltStaon Talk buon currently enabled on
the selected channel, as well as the BaseStaon local headset connector. If the Mic Kill buon is pressed and held
for three seconds, all wireless BeltStaon Talk buons on all channels are disabled. A wireless BeltStaon user may
enable a Talk buon at any me aer the Mic Kill buon is pressed and released. The “OFF” indicator appears in place
of the “TALK” indicator on the BeltStaon display and the user will not hear sidetone if both Talk buons are OFF.
5- Local Headset Channel LEDs
The four Local Headset Channel LEDs labeled A through D indicate the currently selected intercom channel for
the BaseStaon local headset. Only one channel may be selected at a me. Pressing the Volume control while in
Operaonal Mode cycles the Channel LEDs in order from A through D.
6- Peak LEDs
The four PEAK LEDs indicate when the mic audio from the local headset is reaching a peak level and is about to
enter into liming. 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 “BaseStaon Sengs.” Seng the mic gain correctly
is crical for quality communicaon audio.
