The Lowell PA250A is a power amplifier that provides 250 Watts of continuous RMS power directly to an 8 ohm speaker load. It has a switch in the rear that connects internal 20V/70V output transformer for distributed speaker systems. The PA250 can be used to increase the power capability of Lowell's MA Series mixer-amplifiers, or it can serve as an all-in-one telephone system paging solution.
| AC Supply Voltage | 120VAC 60Hz ±10%, 6A circuit breaker |
|---|---|
| Power Consumption | 720W @ Rated Power |
| Power LED (green) | Green LED Lights when product is receiving power |
| Convenience Outlet | 120VAC @ 2A maximum |
| Speaker Level Outputs | Screw terminal strips, 8 ohms bridged, 25V, 70V, 250W RMS |
| Peak LED (red) | If peak LED flashes red, it indicates peaks are approaching full power. Steady red light may indicate the amplifier is being over-driven, there is sub-sonic or ultra-sonic oscillation in the system, or the amplifier is loaded with a shorted speaker line |
| TEL-PAGE Input | Screw terminals, 50mV @ 600 ohms balanced (required for full rated output power) |
| 600 ohms Input | Screw terminals, 500mV @ 600 ohms balanced (required for full rated output power) |
| Frequency Response | 20Hz – 20kHz ±1dB (8 ohms direct output), 20Hz – 16kHz ±1dB (25V/70V transformeroutput) |
