Wolf 1MS & Wolf 2MS FM Radio Monitoring
Everything under control
Wolf 2MS and 1MS are state-of-the-art FM Radio Monitoring devices, designed to control the signal presence and quality over an FM Distribution Network. Onboard twin tuners allow to accurately scan frequencies, they offer high performances in FM reception, MPX audio encoding and RDS data streaming. This cutting-edge equipment features three main operating modes: continuously reception, bandscan and smart bandscan. With FM static mode the user can focus on a single channel, selected and monitored exclusively. Thanks to the scan mode up to 32 channels for each tuner can be scanned and supervised in a single analysis. FM static mode also receives up to 64 memories. Wolf 1MS and 2MS allow to manage accurately RF, MPX, RDS, Audio and RDS data dynamic services. In smart mode the channel scan time is adjusted automatically according to instantaneous measurements requirements
Models
For simple configurations that do not require NMS software, Wolf can send via email a daily report of the 24 hours events. Wolf provides a database sheet to manage these information. The two built-in audio streamers are the essential feature of Wolf 2MS (Wolf 1 MS has 1 built in audio streamer). Audio channels can be streamed to a remote logging system that records both, audio and data, coming from the transmitter site. It is also possible to send audio stream to a remote player for audio-on-demand purposes. Users can listen to each single FM tuner and streamed audio anywhere, using all Internet browsers.
Two onboard network interfaces provide maximum flexibility in streaming and connectivity processes. From PCs, tablets and smartphones broadcasters can completely control Wolf and have full access to all data and alarms. When an alarm is trigged, NMS system sends notifications via SMS or email or takes an action to manage any possible issue.
External input sources are available: analog Left + Right and digital AES/EBU inputs. Users can connect audio to the controlled external input sources. These audio inputs are constantly monitored: silence detection, and audio presence. Tests, performed also by end users, have shown that Wolf circuits are extremely safe and completely free from any kind of radiofrequency interference.
