The CAP21 Advanced 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.
This device supports the connection of two external sensors to register music levels in two different spaces. What’s more, it can remotely send the registered noise levels via telematics and can be connected to an external display to check noise levels on site and show users that they are in a room which isn’t exceeding healthy limits.
The CAP21 Advanced sound limiter boasts optimum sound quality and achieves a powerful level of music with no variations caused by background noise. It’s the highest-rated limiter by today’s most popular DJs, thanks to its frequency response, which can limit sound by bands and maintain optimal audio quality.
The CAP21 Advanced sound limiter is an ideal accessory for soundproofing premises.
Applications: music bars, clubs, pubs, concert halls, theatres, restaurants, etc.
