About this item
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.
Music and Paging Management
Use this module to manage a music feed and automatically fade in and out when a voiceover is played over your paging system.
Audio and Voice Sources
Use almost any line-level audio source for music and a line-level voice source to configure this unit for music and paging.
LEDs
LEDs on this unit facilitate its setup and management by providing a visual indicator of line status.
Consistent Audio Levels
A special compressor on the module maintains a consistent level of volume with audio despite changes in the audio source.
