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.

At a glance

  • Comply with Sound Limits
  • Green - amber - red indication
  • Audio file recording

Overview

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.

XL2 Limit Light

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.

Gives You the Green Light

The tricolor Limit LED or the optional external Limit Light gives you the green light when you are within the prescribed limit. It turns yellow or red when reaching or exceeding the pre-set limits.

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.

XL Level View

Connect the XL2 Sound Level Meter to a computer (PC or MAC) and run the Projector PRO software. The optional XL View 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.

Sound Level Predictor

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.

Remote Sound Level Monitoring

NoiseScout connects the XL2 Sound Level Meter to the web. Start and stop the measurement using your preferred web browser on a mobile phone, tablet or computer. The sound levels are presented with a pre-warning amber or alarming red color in case preset limits are exceeded.

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. Even a view-only link may be forwarded to stake holders, such as neighbors or officials, for their online monitoring.

XL View

XL2 + Projector Pro is a necessary tool for a live sound engineer. XL View displays the selected SPL values on the PC-screen, so you don’t need to look aside to the XL2 display while working on the mixing console. If the SPL exceeds the limit you’ve set, the PC screen will start “screaming” red, signaling that the maximum has been reached.

Sound Level Predictor is an indispensable tool during the show. The parameters displayed by the program are unique. It's like an "Attention Assist" in a car. Analyzing the information received, you won’t exceed the local level limit regulations. At the same time, you will have the necessary SPL in reserve for the loud climax of your show. Based on the above mentioned, Projector PRO is the best tool for a live sound engineer to control SPL in the process of mixing.
