Wolf 2MS and 1MS are state-of-the-art FM radio monitoring devices designed to monitor the presence and quality of the signal on an FM distribution network.

Dual tuners on board allow you to precisely scan frequencies, offer high performance in FM reception, MPX audio encoding and RDS data streaming.This state-of-the-art equipment features three main operating modes: continuous reception, bandscan and smart bandscan.

With static FM mode the user can concentrate on a single channel, selected and monitored exclusively. With the scan mode, up to 32 channels can be scanned and supervised for each tuner in a single analysis. Static FM mode also receives up to 64 memories. Wolf 2MS and 1MS allow you to precisely manage dynamic RF, MPX, RDS, Audio and RDS data services. In intelligent mode, the channel scan time is automatically adjusted to the needs of instant measurements.

Wolf 2MS and 1MS are the ideal probes for a network management system.

All data and information acquired during FM monitoring can be collected from a control room and used to analyse FM network performance in real time or in the past.

Models For simple configurations that do not require NMS software, Wolf 2MS can send a daily 24 hour event report by email.

Wolf 2MS and 1MS provide a database card to manage this information. The two integrated audio streamers are the essential feature of Wolf 2MS (Wolf 1 MS has 1 integrated audio streamer). The audio channels can be transmitted to a remote recording system that records both audio and data from the transmitter site. It is also possible to send the audio streamer to a remote player for audio-on-demand purposes. Users can listen to each individual FM tuner and stream audio anywhere using all Internet browsers.

Two onboard network interfaces offer maximum flexibility in streaming and connectivity processes. From PCs, tablets and smartphones, broadcasters can fully control Wolf 2MS and 1MS and have full access to all data and alarms. When an alarm is triggered, the NMS system sends notifications via SMS or e-mail or takes action to deal with any possible problems.

External input sources are available: analogue Left + Right and digital AES/EBU inputs. Users can connect audio to controlled external input sources. These audio inputs are constantly monitored: silence detection and audio presence. Tests, also performed by end users, have shown that Wolf 2MS circuits are extremely safe and completely free from any kind of radio frequency interference.

Starlight is a digital stereo encoder for broadcast applications that has been designed using highly innovative technology.

The result is the most advanced that a stereo broadcasting system can offer, with an exceptional array of features.

Besides guaranteeing excellent stereo separation between channels, AEV’s Digital Stereo Encoder ensures a transparency of sound never before reached, whilst maintaining exceptional stability.

Starlight can be installed instantly and can be matched perfectly to any transmission system without calibration.

STEREO CODER

It employs a digital modulator at a sampling rate of 32x that generates frequencies at 19 and 38 KHz for respectively the pilot and subcarrier. The employment of a great quantity of “samples” offers a better spectrum clarity and mantains the MPX signal constant. The stereo separation levels are constantly over 65 dB.

COMPOSITE PROCESSOR:

In order to limit the overshoots, Stargate uses “DSP-Filtering” system composed with a couple of digital low-pass filters, an exclusive AEV “hybrid”, that allows not only a phase linear design, but also dynamically flat responses together with 115 dB/oct slope.

The qualities of this system grant perfect spectrum clarity up to 15 KHz.

At the modulator output another “Safety Clipping” stage removes the remaining overshoots produced by the filters.
