How to Install Electro-Voice PA1250T Amplifier

• Plan the rack layout and ensure adequate ventilation around the amplifier. Place the PA1250T in a well-ventilated area of the rack or equipment room to prevent overheating during extended use.
• Mount the amplifier in a standard equipment rack using the appropriate mounting screws and hardware. Verify that the mounting location allows clear access to the rear input/output connections and power switch for safe operation and serviceability.
• Connect the AC power supply to a properly grounded outlet matching the amplifier’s requirements. Use a dedicated circuit if possible to minimize noise and interference from other equipment.
• Wire the audio input from your mixer or audio source to the PA1250T’s input connector(s) with balanced cables when possible to reduce hum and noise. Set the input level controls conservatively and gradually increase as you test the system.
• Connect your loudspeakers to the amplifier’s output terminals, ensuring the speaker impedance or load matches the amplifier’s specifications and that all connections are secure. Use quality speaker cables rated for the load and keep runs as short as practical to minimize loss.
• Power on the system and perform a cautious test. Monitor the amplifier for heat buildup and listen for clean, undistorted output. Adjust input levels and gain as needed to avoid clipping while maintaining intelligible speech and musical clarity.
• Document the configuration (inputs, levels, and routing) for troubleshooting and future maintenance. If you plan to integrate additional amplifiers or zones, label cables and keep a clear rack diagram for quick reference.
