Tempest900 2-Channel Operating Manual
Steps to Congure a Multiple BaseStation System
• Locate and congure antennas to minimize RF interference.
• Make Accu-Sync connections.
• Make 2-Wire Connections.
• Congure for the appropriate 2-Wire connections.
• Null each BaseStation.
• Adjust IN/OUT levels if necessary.
Audio Connections for Multiple BaseStations
When using multiple Tempest BaseStations, it is often desirable to share the same communication channels across some or all BaseStations. To
accomplish this, 2-Wire intercom connections must be made between the BaseStations.
It is advisable to congure the Accu-Sync option prior to making the audio connections.
There are two specic modes of operation when using this feature.
When an external hard wired intercom system is NOT present:
Tempest is designed to use any connected 2-Wire intercom system’s power source and termination to power the BaseStation’s internal hybrid
circuitry. When no hard wired system is present, Tempest uses a feature called Master Mode to power and terminate this circuitry. Audio will not
be shared among the BaseStations until one of the linked BaseStations is set to Master Mode.
Master Mode only functions when there is no 2-Wire hard wired intercom system connected. If there is a hard wired intercom connected to any
channel of any of the shared Tempest BaseStations, Master Mode will automatically disengage and only channels connected to the hard wired
intercom system will continue to be shared.
In Master Mode, the number of Tempest BaseStations 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 5 BaseStations to be linked.
Using the 3-PIN XLR male or female connectors on the back of the BaseStation, connect the intercom channels of each BaseStation that will
share audio.
Set any one of the BaseStations to Master Mode “On.” It is only necessary to set one BaseStation 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 BaseStation is in Master Mode, audio will be shared among all BaseStations that are connected to that intercom channel. Lines must
be nulled for proper operation.
The 2-Wire Intercom Type Select Switch on the Tempest BaseStation front panel must be set to “Clear-
Com” for Master Mode to function.
