Axel Technology Puma Re-Broadcast Receiver | RF-FM Monitoring / Audio over-IP encoder.

Whereas FM broadcaster requires cost effective solution to deliver and re broadcast FM content, Puma is cutting edge, most complete and innovative equipment on broadcast marketplace. Axel Technology with Puma set a new industry standard in hardware DSP-based radio equipment.
Puma is high quality frequency-agile FM Re-Broadcast receiver. In addition Puma provides RF-FM monitoring functionalities and an Audio-over-IP encoder in a single equipment.
Thanks to its internal digital-based DSP improved FM tuner, Puma returns a complete MPX signal from the received FM frequency. The MPX circuit optimization assures a high quality MPX signal that can be used to feed directly an FM transmitter or a different MPX signal path with unprecedented MPX performances
Internal  tuner  assures  strong  performances  in  FM  reception,  RF  and  MPX  audio  analysis  and  RDS  data stream output.  The  monitoring  made  on  the FM  channels  can  be  a  basic  RF  analysis  or  an  advanced  RF, MPX  and AUDIO measurement.
The monitoring made on the RF and MPX signal are:
Mono level, Pilot level, Audio  and RDS levels are measured and kept always under control. All captured data during FM  Channel  monitoring  can  be  sent  to  a  Network  Management  System  (such  as  Axel  Technology’s  Ranger) or showed in a common  password protected web page. Communication between Puma  and Ranger NMS is SNMP v2C  protocol.  For  all  single  parameter  under monitoring,  a  threshold  can  be set.  If  one or more values rises out of range, alarms are delivered.
RF sensitivity of 20-30dBuV will be still available for the use as audio and RDS-UECP re-broadcaster. Once the RF signal  is  received,  audio  should be  streamed  from the  transmitter  site  back to  a remote logging system.  The streamer input allows an internal selection between all inputs available: Tuner, External Analog In, External AES/EBU In.
Puma is also completed with “External Input” source: analog Left Right input and Digital Left Right in AES/EBU format. This audio input is continuously monitored: silence detection (Threshold/time and level), left and right presence, peak left, peak right. Rear-panel audio output always presents the audio decoded from Tuner and this setting is user definable while audio is available on Analog or AES/EBU format.
Puma provides a large variety of connection: double Ethernet port, USB and front panel headphone output, 4x GPIn opto coupled and 4x GPOut over relays. Rs232 serial port for RDS-UECP bridging and rebroadcasting purposes, and rear panel placed SD card to store or recall the complete equipment configuration.
RF antenna input is over BNC connector, a XLR balanced stereo analog input and output, AES/EBU input and output. MPX output is also over BNC connector. OS and data are loaded and stored over solid state memory as SD and flash RAM. Universal switching power supply to operate worldwide, 1 rack unit space in fan-less configuration.
