Smart Audio Limiter Trigger (SALT)
The Gov'nor holds a hard line at the mixer. SALT does the same job digitally — and it brings its own ears. A small in-room sensor listens to the actual level in the space, not just the signal on the wire, and holds your studio at the level you set. When the room pushes past the line, SALT eases it back down and lets go when it settles. Below the line, nothing changes. Your music stays clear, your EQ stays yours, and the vibe stays intact.
Set it up in minutes. Power the sensor over USB-C and run SALT standalone, or link it over Cat6 to a Fitness Audio Aeromix mixer for full integrated limiting. No rack technician, no dashboard, no monthly software.
Whether integrated into Fitness Audio systems or deployed alongside your existing Aeromix mixers and the Gov'nor SPL limiter, SALT provides precise, enforceable sound control in high-energy studio environments.
Spec sheets and manuals
SALT · Smart Audio Limiter Trigger
Listens to the room. Holds the line.
A small in-room sensor measures the level your members actually hear, not just the signal on the wire. Cross the level you set and SALT triggers limiting in connected Aeromix mixers and SPL systems, then lets go when the room settles. Below the line, nothing changes.
How it works
Volume creep, handled without a conversation.
Volume creeps up one notch at a time, class after class. SALT removes the negotiation: the level you set is the level the room keeps, at 6 AM and 9 PM, whoever is teaching. The screen shows the live reading and the state, so anyone walking the floor knows what's happening.
Your music, your EQ and your mix are untouched below the line. When the room pushes past it, SALT eases the level back and releases as soon as it settles.

For the owner
Set the level once to match your lease, your neighbors and your local noise rules. From then on it holds, with no manual intervention and nothing for an instructor to argue with. The three states on screen tell the front desk as much as they tell the instructor.
For the installer
Sensor in the room, in the main output path after the mixer and before the amp. Relay out (NO, COM, NC) with +5V and +VIN/-VIN terminals on the back. A Cat6 link to an Aeromix unlocks the full set of automated limiting; alongside The Gov'nor it adds the room's own ears to a hard ceiling.
Installers and dealers can apply for trade pricing.
Want a hard ceiling at the rack instead of a sensor in the room? That's The Gov'nor. Want the level on the wall for the class to see? That's The Trigger.

Key Features
Listens to the room, not the mixer
SALT measures what your members actually hear. A calibrated internal microphone reads real in-room sound pressure, so a bass-heavy playlist or a packed class registers the way it should — as louder — even when the mixer's meters say otherwise.
Three lights, one story
Green means all clear. Warning means the room is approaching your line. Limited means SALT has stepped in and limiting is active. Anyone walking the floor — instructor, manager, front desk — knows the state of the room at a glance.
Triggers the gear you already own
When the room crosses your configured level, SALT sends the signal link that activates the noise-reduction and limiting features in connected mixers and SPL systems. It sits in a standard mixer → amp → speakers chain, and connects to Fitness Audio Aeromix mixers over Cat6 for the full set of limiting options.
Automation instead of arguments
Volume creep happens one notch at a time, class after class. SALT removes the negotiation: the level you set is the level the room keeps, at 6 AM and 9 PM, whoever's teaching. No manual intervention, no policing, no repeat conversations.
FAQ
Question not answered here? Email info@fitaud.com.
Will this work with my current mixer and PA?
Yes. SALT is designed to work with most standard studio sound systems — mixer → amp → speakers. If you're using Fitness Audio mixers, it integrates even more cleanly via Cat6 for full limiting options.
Does it change how the music sounds?
No. It doesn't color your audio or change your EQ. It monitors sound levels and only intervenes if levels push past your set threshold — your sound stays clear and professional, just controlled.
Where does it install in the signal chain?
In the main output path — typically after the mixer and before the amp and speakers — with the listening unit placed in the room it's monitoring.
What do the three lights mean?
Green: levels are inside your limit. Warning: the room is approaching the line. Limited: the threshold has been crossed and limiting is active.
Do I need other Fitness Audio equipment?
No for standard setups — SALT works in a conventional mixer-to-amp chain. Pairing it with Aeromix mixers over Cat6 unlocks the complete set of automated limiting features.
