RDL ST-VP1 Voice-Over, Paging Module, Manual

Put professional voice-over and paging control exactly where you need it. The Radio Design Labs ST-VP1 voice-over/paging module delivers high-quality, line-level mixing for music-and-voice applications, ideal for paging, mass notification and security/monitoring systems. With dedicated MUSIC and VOICE inputs, you can wire background audio and a paging source (telephone paging or a preamplified microphone) into a single output feeding a paging amplifier. Choose FADE mode to duck music under announcements or CUT mode for an immediate, attention-getting page. Multi-turn trimmers let you set fade depth and fade rate precisely while noiseless electronic switching maintains message intelligibility in surveillance and A/V installations. The compact Stick-On form factor features a durable adhesive mount for quick placement and continuous-duty reliability in professional environments. Use the ST-VP1 alone for simple paging or cascade multiple units for prioritized messages and advanced mass-notification schemes. Add the ST-VP1 to your next security, monitoring or AV deployment to improve clarity and control — contact your supplier to order or to discuss system integration.
