We call it The Trigger. It's a Loudness Monitor - the built-in microphone continuously measures the noise level in the room and displays it in coloured LEDs up to a pre-determinded level of loudness you pre-set from 79dB to 109dB in 3dB steps. You can use it as a stand alone product with the 24V DC Powerpack supplied.
Alternatively, you can connect it up to The Gov^nor, for the additional cost - it's our Sound Pressure Level Limiter. Connect the two items using 2 pairs of a Cat 5 cable run. 24V goes up one pair to power it while the control signal comes down to the Gov^nor on another pair to 'trigger' the limiting action. Either way, once it's set at the maximum level you want in that room the top 3 Red LEDs will tell you when you are there and The Gov^nor will hold it at that level.
The Loudness Monitor measures sound in either A Weighting (required by Government Authorities) or C Weighting (recommended by audio engineers if too much bass is the problem). The Fitness Audio Trigger & Gov^nor are simple solutions to an ongoing problem at any venue - not just fitness clubs!
