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
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.
