60 Tempest®24 00 4-Channel Wireless Intercom System
Steps to Confi gure a Mul ple BaseSta on System
• Locate and con gure antennas to minimize RF interference.
• Make Accu-Sync or ZSync connec ons.
• Make 2-Wire Connec ons.
• Con gure for the appropriate 2-Wire connec ons.
• Null each BaseSta on.
• Adjust IN/OUT levels if necessary.
Audio Connec ons for Mul ple BaseSta ons
When using mul ple Tempest BaseSta ons, it is o en desirable to share the same communica on channels across some or
all BaseSta ons. To accomplish this, 2-Wire intercom connec ons must be made between the BaseSta ons.
It is advisable to con gure the Accu-Sync op on prior to making the audio connec ons.
There are two speci c modes of opera on 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 termina on to power the
BaseSta on’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 BaseSta ons un l one of the linked
BaseSta ons is set to Master Mode.
Master Mode only func ons 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 BaseSta ons, Master Mode will automa cally
disengage and only channels connected to the hardwired intercom system will con nue to be shared.
In Master Mode, the number of Tempest BaseSta ons that can be linked is only limited by RF factors, which is
impacted by antenna loca on and other environmental factors. Widely distributed antennas may permit up to 10
BaseSta ons to be linked.
Using the 3-PIN XLR male or female connectors on the back of the BaseSta on, connect the intercom channels of each
BaseSta on that will share audio.
Set any one of the BaseSta ons to Master Mode “On.” It is only necessary to set one BaseSta on to Master Mode.
Master Mode se ngs are found at the “Set Base as Master” screen under the “Mul -Base Se ngs” of the Main
Menu.
Once one BaseSta on is in Master Mode, audio will be shared among all BaseSta ons that are connected to that
intercom channel. Lines must be nulled for proper opera on.
The 2-Wire Intercom Type Select Switch on the Tempest BaseSta on front panel
must be set to “ClearCom” for Master Mode to func on.
