International orders*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.
LEDs facilitate setup of the unit and also provide visual cues related to the correct operating levels of each of the (2) inputs. The music input includes an AGC compressor that maintains a consistent level of audio from varying music sources. This design feature ensures that the volume level does not change randomly and that voice-overs are not masked during paging.
