Amplifier (PZA )
20W, 4Ω/25V/70.7V/100V mono power amplifier.
The TSD-PA20VG is a cost-effective mono amplifier for 4 Ω distributed constant voltage speaker systems. Applications include hallways and classrooms. The TSD-PA20VG is also a cost-effective alternative for small projector systems, as it can be used with up to (16) 25/70/100V ceiling speakers (with 1W each), and its extremely small size allows for easy mounting.
For sound masking applications, the TSD‑PA20VG has the capacity to drive up to 34 masking speakers connected at 0.5 W each on a 70.7 V line. The output is controlled from a front panel potentiometer with removable knob.
The unit requires a power supply that Sold separately for proper operation; multiple TSDs can be powered with one power supply depending on current requirements. You must use the TSD24V2500MA power supply. For multiple TSD applications, use the TSD Energy Calculator to determine the appropriate power supply needed.
