TSD-PA20VG 20W Mono 4Ω/25V/70.7V/100V Power Amplifier
The AtlasIED TSD-PA20VG is a compact, cost-effective mono power amplifier designed for bothlow-impedance and distributed constant-voltage speaker systems. Delivering up to 20 watts ofoutput power, the TSD-PA20VG is ideal for classrooms, hallways, paging systems, backgroundmusic applications, projector audio systems, and sound masking installations where reliableperformance and installation flexibility are essential.
- 20-watt mono amplifier for commercial audio applications
- Supports 4Ω, 25V, 70.7V, and 100V speaker systems
- One balanced audio input for professional system integration
- Front-panel level control with removable security cover
- Input signal and peak indicator LEDs for system monitoring
- Removable Phoenix-style I/O connectors for easy installation
- Integrated cable management system for organized wiring
- Compact chassis design for mounting in space-constrained locations
- Energy-efficient operation with low power consumption
- Ideal for paging, background music, projector audio, and sound masking systems
Designed for versatility, the TSD-PA20VG can power both traditional low-impedance speakers andconstant-voltage distributed audio systems. It can support up to sixteen 25V, 70.7V, or 100Vceiling speakers tapped at 1 watt each, making it an economical solution for distributed soundapplications in educational, commercial, and institutional facilities.
For sound masking installations, the amplifier can drive up to 34 masking speakers tapped at0.5 watts each on a 70.7V line. This capability makes it an excellent choice for offices,healthcare facilities, and other environments where speech privacy and acoustic comfort areimportant.
The front-panel output level control allows for quick adjustment during setup and includes aremovable knob with a "set-it-and-forget-it" security cover to help prevent unauthorizedadjustments after installation. Input signal and peak LEDs provide visual confirmation of systemstatus and operating levels.
Additional installer-friendly features include removable Phoenix-style connectors for simplifiedwiring, integrated cable management for clean installations, and a small-footprint chassis that canbe easily mounted in classrooms, equipment racks, lecterns, cabinets, and AV enclosures.
The TSD-PA20VG requires a 24VDC external power supply, sold separately, allowing flexibledeployment alongside other AtlasIED Time Saving Devices (TSD) products.
Ideal Applications
The TSD-PA20VG is ideal for classrooms, hallways, conference rooms, waiting areas, retailenvironments, hospitality venues, paging systems, projector audio systems, background musicdistribution, and sound masking installations.
