Audio Connections for Multiple Base Stations
When using multiple Tempest base stations it is often desirable to share the same communication
channels across some or all base stations. To accomplish this, 2-Wire intercom connections must be
made between the base stations.
It is advisable to configure the Accu-Sync option prior to making the audio connections.
There are two specific modes of operation when using this feature.
When an external hardwired intercom system is NOT present:
Tempest is designed to use any connected 2-Wire intercom system’s power source and termination to
power the base station’s internal hybrid circuitry. When no hardwired system is present, Tempest uses a
feature called Master Mode to power and terminate this circuitry. Audio will not be shared among the
base stations until one of the linked base stations is set to Master Mode.
Master Mode only functions when there is no 2-Wire hardwired intercom system connected. If there is a
hardwired intercom connected to any channel of any of the shared Tempest base stations, Master Mode
will automatically disengage and only channels connected to the hardwired intercom system will continue
to be shared.
In Master Mode, the number of Tempest base stations that can be linked is only limited by RF factors,
which is impacted by antenna location and other environmental factors. Widely distributed antennas may
permit up to 10 base stations to be linked.
The 2-Wire Intercom Type Select Switches on the Tempest base station front panel must be
set to “ClearCom” for Master Mode to function.
Using the 3-PIN XLR male or female connectors on the back of the base station, connect the intercom
channels of each base station that will share audio.
Set any one of the base stations to Master Mode “On”. It is only necessary to set one base station to
Master Mode. Master Mode settings are found at the “Set Base as Master” screen under the “Multi-Base
Settings” of the Main Menu.
Once one base station is in Master Mode, audio will be shared among all base stations that are
connected to that intercom channel. Lines must be nulled for proper operation.
When an external 2-Wire hardwired intercom system IS present:
Set the 2-Wire Intercom Type Select Switches to the proper type and select 2-Wire mode. Connect the
hardwired intercom to the base station. In this configuration each connected Tempest base station
intercom channel will receive power and termination from the wired intercom system. The Tempest base
station functions as an additional wired beltstation from the perspective of the connected 2-Wire system.
Connect either male or female (male and female connectors are electrically identical) 3 pin XLR from the
2-Wire intercom channel to be shared, to the base station that will use the intercom channel. Loop to
other base stations as needed. Repeat for all channels to be shared. See the Wired Intercom Interface
