The AtlasIED TSD-PA20VG is a mono power amplifier engineered for cost-effective distributed audio in commercial installs where space and budget are primary constraints. Supporting 4Ω low-impedance loads alongside 25V, 70.7V, and 100V constant voltage lines, it fits a wide range of installed speaker topologies without requiring additional step-up transformers. Typical deployments include classrooms, hallways, small conference rooms, and paging zones where a reliable, unobtrusive amplifier is required.
For sound masking applications, the TSD-PA20VG can drive up to 34 masking speakers tapped at 0.5W each on a 70.7V line — an unusually high speaker count for an amplifier in this footprint class. Integrators working on small projector systems can also leverage its support for up to 16 ceiling speakers tapped at 1W each on 25V, 70V, or 100V lines. The removable Phoenix-style I/O connectors and built-in cable management simplify termination during rack or surface installation.
Front-panel level control includes a removable knob with a set-and-forget security cover, reducing post-commissioning tampering risk in public or semi-supervised environments. Input signal and peak indicator LEDs provide quick visual monitoring without additional test equipment. The unit requires the TSD24V2500MA external power supply, sold separately; multiple TSD amplifiers can share a single supply based on current draw, making multi-zone deployments more economical.
