RDL ST-VP2 Automatic Ducking Module

The ST-VP2 Automatic Ducking Module from RDL is a device designed to cut out music when a page is played over your audio system and automatically fade the music back into play when the page is finished. Use of the unit requires a line-level music source from a receiver, satellite decoder, tape, or CD source. The line-level voice source may be provided from a telephone paging system at line level or from a microphone that has been preamplifed to line level.
