The AxelTech Wolf 2MS Dual FM monitor and Streaming unit is an FM monitoring system designed for FM Off Air signal monitoring purposes. The Wolf 2MS allows the broadcaster to receive up to two frequencies thanks to an internal double tuner. Tuners are independent and they can operate in three ways: Continuous reception, Bandscan and SmartScan.Internal tuner ensures high performances in FM reception, RF and MPX audio analysis and RDS data stream output. The monitoring made on FM channels can be a basic RF analysis or an advanced RF, MPX and AUDIO measurement.
During continuous reception mode, each single tuner checks and completely decodes the multiplexed signal:Mono level, Pilot level, Audio and RDS levels are measured and they are always under control. All data, captured during FM Channel monitoring, can be sent to a Network Management System (such as AxelTech’s Ranger) or they can be shown in a common password protected web page. Communication between Wolf and Ranger NMS is SNMP v2C protocol. For all single parameters under monitoring, a threshold can be set. If one or more values go out of range, alarms are delivered.
Once the RF signal is received, audio should be streamed from the transmitter site back to a remote logging system. The streamer input allows to do an internal selection between all inputs available: Tuners, External Analog In, External AES/EBU In. The Wolf 2MS has an an “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-1 or Tuner-2 and this setting is user definable, while audio is available on analog or AES/EBU format.
The Wolf 2MS 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 inputs are over BNC connectors, a XLR balanced stereo analog input and output, AES/EBU input and output. OS and datas are loaded and stored over solid state memory as SD and flash RAM. Universal switching power supply, 1 rack unit space in fan-less configuration, allows to operate worldwide.
