Price Guide: POA

Successfully installed in 1000s of venues, this unit has been designed by installers to overcome the drawbacks of other products. The main control unit, which is housed in a tough steel case can be fitted at a convenient location out of sight when used with the optional remote indicator. The remote indicator and remote sound pickup microphone are connected using low voltage cable for ease of installation. Simple to fit and operate, the NLX noise limiter incorporates the latest features and is local authority approved. With fully automatic operation, 30 Amp switching capability and built in fire alarm interface this noise limiting device offers straightforward installation and adjustment at a low price.

The sound level in the venue is monitored by the remote microphone and if the preset level is exceeded the amber and red LEDs on the unit begin to light sequentially as a warning. If the sound remains too loud for a period of approximately 10 seconds mains power is disconnected from the sound equipment for 10 seconds and then automatically reconnected; thus no user intervention is required for operation. The trigger level is adjustable as is the sensitivity to bass and treble frequencies. Similarly the trigger / reset time period can be altered if required.

Door / window switch power cut-off connection is available.

An additional sound level is available as an optional extra. This allows two separate volume levels to be set. Door / window switches can then be connected to reduce the permissible sound level when doors or windows are left open or a timer can automatically change levels for different times of the day / night.
