The Gov^nor by Fitness Audio is a 1RU rack mounting Sound Pressure Level Limiter. It is usually connected between the mixer outputs and the power amplifier inputs.
When connected to The Trigger using a length of Cat 5/6 cable it will be your sound level "cop". It partners with the Gov^nor to hold the sound level at say 94dBA if it is exceeded for more than 8 seconds at any time. The limiting action only lets go when the operator reduces the volume below the SPL pre-set on the Trigger.
The Trigger can measure a 30dB range in eleven 3dB steps from 79-109dB in either A or C Weighting ranges. "A" Weighting is normally used for healthy hearing levels measured over time. Use "C" Weighting if there's too much bass energy leaking from the venue and upsetting the neighbours! The light bars move faster and hit the red peak levels sooner using "C" Weighting. There's a Loudness v Time Guide printed on the back of the Trigger to help you decide the level to set.
The Gov^nor comes with a rear control cover to protect the Threshold and Limiting Levels. Once set, you can secure them with kevlar cables complete with serial numbered Ammo Box tags (Australia). The front panel shows a 2 channel LED display of the dB level passing through the unit.
