Overview

Multiband Limiter & Sound Level Recorder

The SPL6 is an advanced audio level limiter that stores the sound level samples for at least twelve months. The sound level samples can be viewed using the internal web pages or externally stored through automatic email. Other important data is also stored like powering up, sanctions or possible fraud attempts.

Using the web interface the SPL6 can be read out and adjusted. There is no separate platform depended software required. All users can only view settings and logging. To adjust configuration settings an additional password and license file is required. To connect to the SPL6 a computer or tablet must be equipped with a network connection. When connected to a network or the Internet, the SPL6 can be remotely monitored.

The SPL6 uses a measurement microphone to determine the actual sound level. When measurement shows the sound level exceeding the maximum set level, it will reduce slowly the full sound spectrum to the maximum allowed level. In multiband mode the SPL6 will slightly reduce the single frequency band before adjusting the full spectrum.

With the special correlation detection the SPL6 detects external noise pollution and can ignore for example applauding or screaming audience. This way the maximum sound level is always insured.

The special calender functions allow for different sound levels during the day and year.
