Live Event - Sound Level Monitoring

Live Events Monitoring Solution

Live sound events should be enjoyable; a good quality sound and an entertaining show are the foundation for this. It is also important that the sound level does not cause discomfort or damage to the audience’s hearing, nor disturb the neighbors. The XL2 Sound Level Meter is the professional sound level measuring solution for such occasions

Comply with Sound Limits

XL2 Sound Level Meter

The XL2 Sound Level Meter helps you comply with sound limit regulations. Simply power up the meter, select the pre-configured measurement profile and press start. The XL2 measures and logs all levels without further user action, and gives you a red light when you are above the limit. A compressed audio wav-file may be recorded simultaneously.

Monitor the loudest point in the venue

The XL2 measures the correction values between the loudest point of the live event and the actual measurement position, e.g. the front-of-house. These correction values are included with the actual measurement data, thus you have the level at the loudest point in the public area under control.


Automated Report

Load the logged data into a report template and play the XL2 audio file to review any periods when the sound was over the limit, but beyond your control, such as when the audience applause was too loud.

On-Site Supervision

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

The XL View

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 XL View requires an installed Projector PRO Option on the XL2 Sound Level Meter.

The Sound Level Predictor View

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.

Remote Sound Level Monitoring

The XL2 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.
