The Symetrix 571 SPL Computer is an automatic level controller that maximizes intelligibility by changing gain in proportion to environmental noise level changes. In essence, controlling the volume of the sound system by measuring the volume of the ambient noise and then adjusting the system gain accordingly. The operating characteristics of the SPL computer are controlled by a powerful microprocessor, running under Symetrix proprietary software. This reduces the 571’s calibration time and allows the installer to optimize performance for any situation
