AtlasIED TSD-PA20VG 20W Mono 4O 25V, 70.7V, 100V Power Amplifier

Optimize distributed audio for paging, sound masking and surveillance monitoring with the AtlasIED TSD-PA20VG 20W mono power amplifier. This compact AtlasIED pro amplifier delivers 20W RMS and selectable 4Ω/25V/70.7V/100V outputs, making it ideal for small classrooms, hallways, retail areas and security paging systems. The TSD-PA20VG’s tiny footprint and energy-efficient design simplify installation in constrained spaces and allow multiple units to be powered from a single 24V DC supply (power supply sold separately; use TSD24V2500MA and the TSD Power Calculator for multi-unit setups).

Installers benefit from a balanced input, removable Phoenix-style connectors and a removable front-level control with a security cover for set-and-forget operation. Signal and peak LEDs provide instant visual monitoring for troubleshooting in AV, security and surveillance environments. Backed by a 3-year limited warranty, the TSD-PA20VG is a reliable, cost-effective choice for distributed audio and monitoring applications. Add this amplifier to your next paging, sound masking or CCTV audio project — contact sales or order today.
