What is the Smart Audio Limiter Trigger (SALT)?

The SALT is an active in-studio decibel listening device designed for fitness facilities. It continuously monitors real-time sound pressure levels using a calibrated internal microphone, and automatically sends a trigger signal to connected mixers or SPL systems when room volume exceeds a preset threshold — creating fully automated volume management without manual intervention.

How does the SALT work?

The SALT listens to the actual sound pressure level in the room using its calibrated internal microphone. When volume crosses your configured limit, it sends a dynamic limiter trigger signal via Cat6 cable to activate noise reduction and limiting inside connected Aeromix mixers or compatible SPL systems — instantly bringing the room back within the safe threshold.

Does it work with my current audio system?

The SALT is designed to integrate with most professional studio sound systems that support an external SPL trigger input. Contact the Fitness Audio team to confirm compatibility with your specific setup before ordering.

Fitness studios are high-energy environments where music and instructor microphones need to be loud enough to drive the class—but not so loud that they cause complaints, hearing fatigue, or regulatory issues.The Smart Audio Limiter monitors the actual sound pressure level in the room and automatically controls the signal when the volume exceeds the defined limit. This ensures consistent audio while keeping studios compliant with building and local sound requirements.

Take control of your studio’s sound environment with the Smart Audio Limiter Trigger (SALT) — an active in-studio decibel listening device designed to monitor real-time sound pressure levels and trigger dynamic audio limiting when preset thresholds are exceeded.

Purpose-built for fitness facilities, SALT continuously listens to room volume using a calibrated internal microphone. When sound levels cross your configured limit, the device sends the required signal link to activate noise reduction and limiting features inside connected mixers and SPL systems.

This creates a fully automated volume management ecosystem — protecting member experience, maintaining compliance, and preventing volume creep without relying on manual intervention.

Whether integrated into Fitness Audio systems or deployed alongside high-end digital mixers, SALT provides precise, enforceable sound control in high-energy studio environments.

An active in-studio decibel listening device for fitness facilities. It continuously monitors real-time sound pressure levels and automatically sends a trigger signal to connected mixers when room volume exceeds a preset threshold — creating fully automated volume management without manual intervention.

Fitness studios need music loud enough to drive classes, but not so loud they cause noise complaints, hearing fatigue, or regulatory issues. The SALT enforces safe, consistent sound levels automatically — protecting member experience and maintaining compliance with local sound requirements.

The SALT listens to the actual room SPL using its calibrated internal microphone. When volume crosses your configured limit, it sends a trigger signal via Cat6 cable to activate limiting inside connected Aeromix mixers or compatible SPL systems — instantly bringing the room back within the safe threshold.

No — the SALT only monitors and intervenes when audio exceeds the preset threshold. Music and microphones remain clear and balanced at normal levels. Limiting is only triggered when the configured limit is breached.

It installs after the mixer and before the amplifier or speakers. It connects to compatible mixers via Cat6 cable using the included female RJ45 connectors, and mounts to a wall or surface using the included surface mount box.

No — the SALT features a coded screen lock that prevents unauthorized adjustment of the configured sound limits. Only authorized facility managers with the code can change settings, ensuring consistent enforcement regardless of who is teaching.

Compatible with Fitness Audio Aeromix 2+2SR and 3+5LS mixers, the Fitness Audio Govn'r SPL Limiter, and most high-end digital mixers that accept an external SPL trigger input.

The SALT is designed to integrate with most professional studio sound systems that support an external SPL trigger input. Contact us to confirm compatibility with your specific setup before ordering.

The SALT supports USB-C standalone power, making it flexible for surface mount installation in the studio without requiring a dedicated rack power supply.

Includes: (1) Smart Audio Limiter Trigger unit, (1) Surface mount box, and (2) Female RJ45 connectors.
