The Electro-Voice PA1250T is a rackmount 250W mono power amplifier with a high-performance output transformer ideal for 50V/70V/100V systems in schools, houses of worship, retail spaces, offices, and more. This single-channel amplifier has a simple, easy-to-use interface with the power switch and indicator LEDs on the front panel, while the stepped level control and switch for the selectable 50/70/300 Hz high-pass filter are on the rear. Euroblock input and output connectors are utilized for quick and easy setup.

Comprehensive protection circuitry protects your amplifier from damage caused by overheating, overloads, and short-circuit issues. The output has a delayed connection at power-up to prevent damage to your speakers. Variable-speed fans and a flow-through-chassis design direct airflow from front to rear, and keep the amplifier cool and running smoothly. Integrated rack ears allow direct mounting of the 2 RU enclosure in a standard 19" equipment rack.
