Inovonics 655 AARON FM/HD Receiver
The Inovonics 655 AARON FM/HD Radio™ Rebroadcast Receiver employs a sensitive FM / HD Radio™ SDR-based receiver that invariably returns to the programmed frequency and reception mode following a power interruption. In addition to FM and HD1-8 program sources for rebroadcast, the 655 accepts analog, AES-digital and streaming program inputs with fallback-priority selection. Outputs are FM-stereo-multiplex (MPX) as well as both analog and AES digital program line outputs and output streaming.
 
IP connectivity with a Web-browser interface permits total remote control of the unit from any PC or mobile device, along with remote audio monitoring. Local GPIO failure alarms are augmented with email notifications, alarm logs, and full support for SNMP operation.
 
Comprehensive audio processing includes gated and ‘windowed’ AGC, a unique ‘syllabic’ leveler, three bands of compression, and both wideband and independent HF limiting. 4 sections of parametric EQ, a ‘Bass Punch’ utility, independent Density and Loud/Smooth adjustments, and variable composite processing round-out the processing function. The AARON 655 includes an onboard RDS encoder that can either pass or regenerate incoming RDS, and can also reformat HD Radio™ ‘PAD’ data for RDS retransmission.
