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 Poweramp inputs. It can be set up manually using a Sound Pressure Level Meter to ensure that the sound pressure level in a room runs at no more than an average of 94dBA for an hour's class or dosage (noise level exposure).
Alternatively, it can be connected to The Trigger Lodness Monitor by Fitness Audio or a SoundEar product for a 24/7 triggered limiting action when the sound level exceeds say 94dBA for more than 8 seconds. The limiting action will let go when the volume levels are reduced below the pre-set level. It comes with a rear control security cover and the front panel shows a 2-channel display of the signal level passing through the unit.
