Available in one of four different versions, the SoundSign Master Unit can be installed quickly to provide clear information about high noise levels. Simply configure the unit and mount it in the location needed.

Enhance your SoundSign with a range of options and accessories

As well as the CR:203 Data Logger and the CR:202 Remote Display Units, we can provide a range of accessories and options to enhance and expand your SoundSign.

If you need to place the microphone away from the SoundSign, we can supply a range of microphone extension cables, preamplifiers and microphone capsules to allow you to put the measurement microphone up to 50m from the SoundSign.

We can also provide acoustic calibrator, a simple CR:306 sound level meter to help you set the trigger level, as well as outdoor microphones if your noise source is outdoors.
