Sound Level Monitoring

The Projector PRO software displays the XL2 screen in real-time via USB on the connected Windows or Mac computer. For repeated event monitoring, e.g. a festival over several days, the sound level monitoring starts automatically when the computer starts up and ends again with the shutdown. All Projector PRO settings can be saved in a software profile

Every XL3 has an online, built-in large screen (XL-View) mode, which continuously streams three selectable levels together with freely-definable limits. Connect with your iPad, your phone, or any browser-enabled large screen such as a smart TV. This allows the levels to be displayed to all interest groups such as FOH, organizers, audience, authorities and neighbors.

The “XL View” window presents sound levels in large size on the connected computer screen. Users may select to view one, two or three sound pressure levels. Exceeding levels are presented with a pre-warning amber or alarming red color.

The “Sound Level Predictor” visualizes the level history of the current measurement interval and indicates the headroom for the actual measurement period or the next few minutes. Green bars confirm that the present level is well below limits. Red bars are a call to action to reduce the sound level at the mixing desk. This allows the front-of-house engineer to optimize dynamic passages of the band for maximum audience satisfaction while still remaining within the legal limits. The Sound Level Predictor View requires an installed Projector PRO Option on the XL2 Sound Level Meter.

The XL2 and XL3 Sound Level Meter can be connected to the web. Start and stop the measurement using your preferred web browser on a mobile phone, tablet or computer. This provides you all levels at a glance at festivals with multiple stages. Adding a measurement station in the neighborhood helps you keep everything under control and prevents complains about exceeding limits. A view-only link may be forwarded to stake holders, such as neighbors or officials, for their own online monitoring.

An outdoor measurement microphone offers a weather-protected measurement solution for our Sound Level Meters. Together they form a dedicated solution for noise monitoring of outdoor live sound events.
