The Shure Model PS1A is an AC power supply that provides phantom power for one or two Shure SM81, SM82, SM85, or other condenser microphones. The PS1A can be used with either balanced or unbalanced low-Impedance microphone inputs, and is designed to handle both microphone and line-level signals. It features extremely low noise, hum and RF susceptibility. The PS1A will operate over a wide range of AC voltages, and provides short-circuit-proof-operation.

The PS1A contains a power switch, power-on indicator, two each male and female XLR connectors, and an internal voltage selector switch for 240-volt, 50/60 Hz operation.
