13.1 Introduction

Webstation Meters is a software tool that lets you as a user monitor and control the Webstation console in an intuitive and user
friendly manner. This manual describes the features Webstation Meters contains and how to setup and use the application.
Software elements

13.1.1 Analog and Digital clock

Webstation meters provides an analog as well as a digital clock which display PC system time the application is running on. The
analog clock contains a seconds dot counter which can be used as indicator for program end time countdown.

13.1.2 PPM meters

Two stereo PPM (Peak-Program-Meters) meters provide real-time and accurate readings of the Master- and CRM(Control Room
Monitor) buss audio levels. A variety of PPM meter scales exist these days with all different ranges and read outs. Based on the
most used scale the following type is used: IEC 60268-10 Type I, DIN scale. This scale ranges from -50 to +5dB.
13.1.3 Silence detection
Since continuous radio is important for a radio station, the Webstation is equipped with a built-in software silence detector
which guards presence of audio signal on the master output. If no sound is present for a specified time, the console generates an
alarm and switches automatically to non-stop mode. When the silence detector is active red line marks in the master PPM bars
indicate the threshold as well as the operating mode which can be left, right or stereo.

13.1.4 MIC ON Timer

The first two modules of the Webstation can be used for connecting microphones. If one of these mic modules is active (source
selector is set to mic, ON is active and fader is up) the MIC ON timer will start. Once the timer is active the elapsed time is shown
in the analog clock area below the system date. The timer will reset if all the mic modules are inactive.
