Inovonics Aaron 655 FM-HD Rebroadcast Receiver

Description Specifications Video Inovonics Aron 655 FM/HD Radio Rebroadcast Receiver The AARON 655 has a sensitive FM/HD Radio SDR receiver that always returns to the programmed frequency and reception mode after a power interruption. In addition to FM and HD, this Re-broadcast receiver can accept 1-8 audio sources for rebroadcast. This all accepts AES digital and streaming audio inputs with fallback priority selection. Outputs include FM stereo multiplex (MPX) and both analog and AES digital Audio line outputs and output streaming. IP connectivity with a web browser interface allows the unit to be fully accessible remotely from any PC or mobile device, along with audio monitoring. Local GPIO trouble alarms are sent via email as are the alarm logs, full support for SNMP operation. Extensive audio processing includes gated and windowed AGC, a unique syllabic leveler, three-band compression and both broadband 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 feature. The AARON 655 has a built-in RDS encoder that can relay or regenerate incoming RDS and also reformat HD Radio™ ‘PAD’ data for RDS Re-broadcasting. Characteristics Uncompromising DSP-based (SDR) receiver performance Accepts program audio from analog FM, digital HD1 to HD8 programs, streaming sources and analog or AES digital line inputs, all with assignable failover audio backup Audio processing with AGC, parametric EQ, bass ‘punch’ enhancement, multi-band compression, independent broadband/HF peak control and composite clipping A regenerated and peak controlled composite/MPX output, plus balanced analog and AES digital program line outputs for amplifiers with built-in stereo coder. An internal RDS/RBDS encoder that can adjust incoming off-air RDS data, convert HD Radio™ PAD to RDS, convert streamed metadata to RDS, or receive IP Telnet data. An intuitive web interface with remote control and remote audio monitoring; Self-logging reception alarms provide immediate notification by e-mail and SMS SNMP monitoring and remote control of all AARON 655 functions A built-in BandScanner™ for a snapshot of the local RF spectrum Downloads Web interface with Remote control, plus alarm notification by email and SMS Tuning Range 87.5MHz – 107.9MHz in 100kHz steps Sensitivity/Noise Performance 5dBμV for 50dB unweighted, monaural analog-FM SNR Off-Air Frequency Response Analog-FM: ±0.5dB, 20Hz – 15kHz HD Radio™: 20Hz – 20kHz (per certification spec.) AUDIO PROCESSING AGC  Gated, ‘gain-riding’ AGC with ±15dB capture range; dualrate ‘windowed’ operation Leveling Variable ‘syllabic’ 2:1 compression normalizes dialog and music sources Parametric Equalization 4-sections of parametric EQ, each with variable frequency, ‘Q’ and gain Bass ‘Punch’ Variable bass enhancement accents the initial bass attack Compression 3-bands of r.m.s. and peak compression with selectable crossover frequencies, variable master and individual band drive controls Final Peak Control Feed-forward final peak limiting eliminates flat-top clipping; independent HF limiter for pre-emphasis protection Composite Clipper 0dB – 3dB adjustable MPX clipping depth (excludes stereo pilot and RDS subcarrier) Processing Presets 10 factory, 10 user-defined presets RDS/RBDS ENCODER Fields Supported  PI, PTY, PS, RT, M/S, TP, DI, CT, AF HD ‘PAD’ to RDS HD Radio™ Name, Slogan, Artist, Title, Album and Genre may be converted to the RDS scrolling-PS and RT fields Streaming Audio Metadata to RDS Streamed Name, Metadata, Description and Genre may be converted to the RDS scrolling-PS and RT fields Telnet to RDS Accepts dynamic PS and Radio Text updates via IP BANDSCANNER™ A built-in spectrum analyzer utility sweeps the entire FM band (or a selected portion) and presents a graphic display of all signals received, includinag RSSI values and HD Radio™ transmissions. Alarms Fault alarms include radio audio loss, analog audio loss, digital audio loss, stream audio loss, low signal, RDS error, stereo pilot loss and HD Radio™ channel loss. Alarms trigger front-panel indications, local (GPO) closures, browser interface notations, SMS/email dispatches, SNMP. Alarm Logs Alarms are logged and may be downloaded as daily, weekly or monthly CSV files. SNMP All setup and operating controls and alarm functions of the AARON 655 are under SNMP management.
