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.
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.
