Audiopole - Limiteur de niveau sonore SPL ONE

The Audiopole SPL ONE sound level recorder limiter is designed to ensure precise and compliant management of sound levels in professional environments.

Compliant with decrees 98-1143 of December 15, 1998 and 2017-1244 of August 7, 2017 as well as the Afnor NF S31-122-1 standard of January 2017, this device ensures effective regulation in overall dBA and dBC levels.

The SPL ONE offers two distinct operating modes. In insertion mode, it acts directly on the broadcast system to maintain sound levels below pre-programmed thresholds, in real time.

In monitoring mode, it monitors ambient sound levels, emits light warnings and can, in the event of prolonged overshoot, cut off the mains power supply via an integrated relay.

Equipped with an embedded web server, the SPL ONE allows configuration and monitoring of sound levels from any computer (Mac or PC) and via any browser, without requiring additional software.

Users can view sound levels, adjust settings and access histories directly online. Recorded data can be viewed for six months, with export options in text, CSV or HTML formats for detailed analysis.

The device also has advanced features such as octave band regulation (in its SPL ONE FB version), fire alarm management, and automatic level reduction when connected doors or windows are opened.

Its installation is facilitated by a complete connectivity: balanced XLR inputs and outputs, RJ45 ports for network connection and remote displays, as well as relay outputs for managing external alerts.

Robust and precise, the SPL ONE adapts to various contexts, from performance halls to public establishments, including work environments requiring rigorous sound regulation.
