The Gov'nor
The volume policy that enforces itself.
Every facility has a volume policy. Almost none of them have a way to enforce it. The sign gets ignored, the staff meeting wears off in a week, and the level creeps up one notch per class until the neighbors, the landlord, or the front desk have had enough.
The Gov'nor is the enforcement. It's a single rack space limiter that sits between your mixer and your power amp with a hard ceiling set at the level you choose. Below the line, instructors mix however they like. The line itself is not negotiable, because it's not a rule. It's wiring.
When paired with The Trigger, the system becomes fully automated — activating limiting instantly when room SPL thresholds are breached.

The Gov'nor · SPL2.2 limiter
The volume policy that enforces itself.
A single rack space between your mixer and your power amp, with a hard ceiling set at the level you choose. Below the line, instructors mix however they like. The line itself is not negotiable.
How it enforces
It's not a rule. It's wiring.
Set the ceiling once, against a handheld SPL meter or from The Trigger's reading of the room, and the Gov'nor holds it from then on. Below the line the signal passes through untouched and instructors mix normally. Cross it and the limiter engages, whatever the mixer is set to.
The four adjustment controls are on the rear under a security cover that closes with wire seals, so any change leaves evidence. Linked with The Trigger, pulling the plug on either unit cuts the signal to the amp instead of removing the limit.

For the owner or manager
You decide the level: house policy, lease conditions, local noise rules. Set it with a handheld SPL meter and it's enforced every class, whoever is teaching. No staff meeting required.
The front panel has one control, the power switch. Nothing an instructor can nudge.
For the installer
Standard 1RU unit, line level in and out between any mixer and any amp. Pair it with The Trigger for level-triggered limiting, or run it in manual mode. Shipping box 20.5 x 8.3 x 3.9 in, 4.4 lb.
Installers and dealers can apply for trade pricing.
Add The Trigger and the room's actual level sets off the limiting, with the reading on the wall for everyone to see.
Key Features
Set it with a meter. Or let The Trigger run it.
Two ways to run the room. In manual mode, you set the ceiling against a handheld SPL meter, for example capping a class at an average level your policy allows, and the Gov'nor holds it from then on. Link it to The Trigger loudness monitor instead and the system watches the actual room: when the sound exceeds your set level, the Trigger activates the Gov'nor's limiting circuit and pulls the volume back to the line, then releases when the level comes back down. No manager required. It works at 6 AM and 9 PM identically.
Sealed against opinions
Volume limiters have a natural enemy: whoever disagrees with them. The Gov'nor's four adjustment controls sit on the rear panel under a security cover that closes with wire seals, so any change leaves evidence. Up front there's a two-channel green-to-yellow-to-red LED display showing the signal passing through, and exactly one control anyone can touch: the power switch.
Fails silent, not loud.
The classic way around a limiter is to pull it out of the chain. Linked with The Trigger, the Gov'nor is designed so that doesn't work: switch off or unplug either unit and the amplifier receives no signal at all. Bypassing the system doesn't get you loud. It gets you silence, which gets reported immediately. The only way to have sound is to have limited sound.
Works with the gear you already own.
The Gov'nor is brand-agnostic: a standard 1RU unit that connects between any mixer's outputs and any power amp's inputs. It completes the Fitness Audio control chain with your Aeromix mixer and The Trigger, but it will hold the line in front of anyone's amplifier.

FAQ
Does it change how the music sounds below the limit?
No. Below your set ceiling, the signal passes through and instructors mix normally. The limiting only engages when the level crosses the line, and it releases when the volume comes back down.
What stops an instructor from just turning it up?
Nothing stops them from turning the mixer up. The Gov'nor stops it from mattering: the level reaching the amplifier cannot exceed the ceiling you set.
What stops someone from changing the Gov'nor's settings?
The adjustment controls are on the rear panel under a security cover you can close with wire seals. Changing the setting means breaking a seal, and a broken seal is evidence.
Can't someone just unplug it?
Linked with The Trigger, no. The system is designed to fail silent: remove or power off either unit and the amp receives no signal. Nobody bypasses their way to a louder class.
How do I choose the right level?
Set it against a handheld SPL meter to match your house policy, lease conditions, and local noise requirements. Many operators reference workplace noise-exposure guidance for class-length averages, but the right number for your rooms is a decision to make with your installer. The Gov'nor enforces the level you choose; choosing it is yours.
Do I need The Trigger too?
No, manual mode works standalone. But the pair is the complete system: The Trigger reads the actual room and shows everyone the level, the Gov'nor enforces it, and together they're effectively tamperproof.
