The CAP21 Basic sound limiter is specially designed device to act on the sound chain, allowing for the control of levels generated by a music system and preventing regulatory noise protection levels from being exceeded. It acts on the whole audio spectrum and without altering the equalisation and sound quality within the premises.
What’s more, it has an external sensor that records the music level within the premises, creating a more pleasant environment with a stable music level and without variations caused by background noise.
The CAP21 Basic sound limiter is configured with the help of a PC and dBconfig software by dBelectronics.
APPROVED BY ALL NATIONAL AND INTERNATIONAL STANDARDS..
CAP21® SOUND LIMITER - RECORDER
- Spectral analysis of the signal in thirds of octave.
- Configurable frequency range between 63 Hz and 20 kHz.
- Configurable to permitted sound levels.
