58 Tempest®900 2-Channel Wireless Intercom System
Steps to Configure a Multiple BaseStation System
• Locate and configure antennas to minimize RF interference.
• Make Accu-Sync connections.
• Make 2-Wire Connections.
• Configure 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 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
BaseStation’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 BaseStations until one of the linked
BaseStations 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 BaseStations, 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 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 “ClearCom” for Master Mode to function.
