PRODUCT OVERVIEW
Wolf 2MS is a state-of-the-art monitoring system, designed to supervise FM air signals. The accuracy of the onboard
twin tuners allows a very rigorous frequencies scan, 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 .
The FM static modality allows to focus on a single channel, selected and monitored exclusively. Scan mode implies
that up to 32 channels for each tuner can be scanned and supervised in a single analysis. Receiving up to 64 memories
in total, Wolf 2MS allows a complete and accurate scrutiny of RF, MPX, RDS, Audio and RDS data dynamic services. In
smart mode the channel scan time is adjusted automatically according to instantaneous measurements requirements.
Outstanding quality of Wolf 2MS is the integration into a Network Management System. Supporting SNMP protocol,
all data and information captured during FM monitoring are graphically displayed on any kind of web interface. For
simplest configurations not requiring NMS software, Wolf 2MS can send via email a daily report of the 24 hours
events. Wolf 2MS provides a database sheet to manage this information.
Two built-in audio streamers are an essential feature of Wolf 2MS; audio channels can be streamed to a remote
logging system that records both audio and data coming from the transmitter site. The audio stream can also be sent
to a remote player for audio-on-demand purposes. From any site users can listen to each single FM tuner and
streamed audio, using any Internet browser.
Two onboard network interfaces provide maximum flexibility in streaming and connectivity processes. From PCs,
tablets and smartphones broadcasters can control completely Wolf 2MS and access all data and alarms. When an
alarm rises, it is the NMS system that sends notifications via SMS or email or takes an action to fix any possible issue.
External input sources are available: analog Left+Right and digital AES/EBU inputs. Users can connect audio to the
external input sources that should be under control. These audio inputs are constantly monitored: silence detection,
and audio presence. Thorough tests, performed also by end users, showed that Wolf 2MS circuits are extremely safe
and completely unaffected by any kind of radiofrequency interferences
TECHNICAL DESCRIPTION
Wolf 1MS and Wolf 2MS are FM monitoring systems designed for FM Off Air signal monitoring purpose. Wolf 1MS is
provided with one high quality FM tuner, while Wolf 2MS allows the broadcaster to receive up to two frequencies
thanks to internal double tuner. Tuners are each other independents and they can operate in three ways:
Continuous
reception , bandscan and SmartScan .
Internal tuner assures strong 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.
- Continuous reception: a single carrier is selected and under monitoring.
- Bandscan mode: a total of 32 FM Channels can be scanned and monitored in Wolf 1MS and 64 FM Channels
for Wolf 2MS. The bandscan time is also user definable, in a range from 1 second up to 10 seconds for each
channel.
- SmartScan mode allows an intelligent and variable scan time that is adjusted automatically to fit the
instantaneous measurement requirements. This is to avoid false-positive rising errors.
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 kept always under control. All captured datas 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 Wolf 2MS and Ranger NMS is SNMP v2C
protocol. For all single parameter under monitoring, a threshold can be set. If one or more values go out of range,
alarms are delivered.
