OVERVIEW

A complete and affordable solution for audio level management.

The Symetrix 371 SPL Computer automatically raises and lowers sound system levels in response to changes in ambient noise conditions.
Designed for installations featuring foreground music and/or paging, it ensures that music and announcements are always clearly audible and distinct, but never too loud. Proprietary AmbiSense technology enables the 371 to continuously monitor changing ambient noise levels not just during gaps in the audio program so it can respond quickly to sudden changes. RC-3 Remote Volume Control is available for the 371.

A simple set of step-through menus displayed on the front panel LCD guides you through setup of the 371. You set the parameters of the acoustic environment and then set the way you want the unit to respond to changes in it. In operation, the 371 tracks environmental noise levels, internal signal levels and all the control settings. It makes appropriate gain changes whenever it finds measured characteristics. Menu adjustments determine how much the gain is changed, and how quickly that change occurs.
