The TSD-PA20VG is a cost effective mono amplifier for 4Ω and distributed constant voltage speaker systems. Applications such as house of worship cry rooms, hallways, restrooms, foyers and classrooms will benefit from this compact reliable amplifier. The TSD-PA20VG is also a cost effective alternative for small projector systems as it can be used with as many as (16) 25/70/100V ceiling speakers (tapped at 1W each), plus the extremely small footprint allows for easy mounting. For sound masking applications the TSD-PA20VG has the capacity to drive up to 34 masking speakers tapped at .5W each on a 70.7V line.
Output is gain controlled from a potentiometer on the front panel with removable knob to facilitate installation of a tamper resistant cover (included).
