Description
The TSD-PA20VG amplifier is an economical solution for mono amplification in 4Ω and distributed constant voltage audio systems. Ideal for settings such as hallways and classrooms, the TSD-PA20VG also serves as a budget-friendly option for small projector systems, supporting up to 16 ceiling speakers at 25/70/100V (tapped at 1W each). Its compact design facilitates easy mounting in various environments. For sound masking applications, it can power up to 34 masking speakers (tapped at 0.5W each) on a 70.7V line. The amplifier’s output gain is adjustable via a front-panel potentiometer with a removable knob. The unit requires a separately sold power supply for operation, and multiple amplifiers can be powered from a single power supply depending on their current needs. For optimal power supply selection in multi-unit setups, use the TSD Power Calculator. Notable features include:
– 4Ω/25V/70.7V/100V output options
– One balanced input
– Removable level control with security cover
– Input signal and peak indicator LEDs
– Integrated cable management
– Removable Phoenix-style I/O connectors
– Energy-efficient compact chassis design
– Power supply sold separately
