The Atlas Sound TSD-PA20VG Mono Power Amplifier is a mono amplifier for 4Ω and distributed constant voltage speaker systems. Applications include house of worship cry rooms, hallways, restrooms, foyers and classrooms. The TSD-PA20V is also an alternative for small projector systems as it can be used with as many as 16 25/70/100V ceiling speakers (tapped at 1 watt each), and its small footprint allows for simplified mounting.
For sound masking applications the TSD-PA20VG has the capacity to drive up to 34 masking speakers tapped at 0.5 watts 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. The unit requires a power supply (available separately) for operation.
