Model Numbers
Currently, there are two models in the RFBA family available: The RFBA and the RFBA Plus. Both units
will be labeled as "RFBA" on the front panel
The RFBA Plus contains every feature of the RFBA, but also adds the ability to operate as a highly
accurate DSP-Based Triple Tuner Modulation Monitor. Every RFBA unit can be upgraded to be an RFBA
Plus via a user-installable software key. If you are interested in upgrading your RFBA unit to the full
capabilities of the RFBA Plus, please contact
Installation and Configurations
Your RFBA is versatile and designed to handle many user configurations. The typical configurations
for the RFBA are: Triple Tuner for EAS/CAP, Triple Tuner Modulation Monitor, Standalone FM
Translator with RDS Encoding, or a Mixed Combination of Other Configurations.
Triple Tuner for EAS/CAP Reception
This all-in-one product allows the user to monitor three separate broadcasts while outputting the audio
to a stand-alone EAS/CAP decoder unit. By separating the tuners from the EAS/CAP decoder, the user
can be assured that the sensitivity of the tuners is not compromised by the harsh EMC noise that is
typically seen in the PC-based EAS/CAP decoder units. In this configuration, the audio signals from the
Phoenix connector may be connected directly to the EAS/CAP decoder unit. The audio level for each
tuner may be digitally adjusted to meet the voltage requirements of your particular EAS/CAP decoder.
The RFBA includes capability for Hi-Jack Avoidance and Squelch functions; in this configuration, users
will typically disable these features. The Hi-Jack and Squelch functions can be adjusted via the front
panel setup menus or via the Ethernet connection.
