Setting Up Levelguard; Security Cover - JBL CS Commercial Solution CSM-21 User Manual

6.8 Setting Up LevelGuard™

To set up LevelGuard™, begin by turning the LevelGuard™ trim pot to twelve o' clock. Use this as your
"baseline" setting. Now turn up the Source volume to the level desired for a particular zone. Check the
LevelGuard™ indicator LED, on quieter passages the indicator should be off. On peak volumes the
indicator should flash amber. If the indicator is constantly on, turn the trim pot clockwise until it flashes
only occasionally. It is useful to set LevelGuard™ so that the LED stays unlit during very low music
volume use, flashes on and off during normal volume use, and then lights continuously as the volume
increases. For best sound quality, use a combination of LED visual cues and adjustments by ear.
