Front Panel Overview

Figure 1: Front Panel of Behringer A800 Power Amplifier
The Behringer A800 Power Amplifier features a clean front panel design. On the left is the volume control for Channel A, and on the right is the volume control for Channel B. In the center, an illuminated LED display provides visual feedback on signal levels, including protection, clip, and output indicators for both channels. The model name 'REFERENCE AMPLIFIER A800' is clearly visible below the display.
Connections
- Power Connection: Connect the supplied power cable to the amplifier's AC inlet and then to a suitable power outlet. Ensure the amplifier's power switch is in the OFF position before connecting.
- Input Connections: The A800 supports various input options. Connect your audio source (e.g., mixer, audio interface) to the amplifier's input jacks using appropriate cables (XLR or TRS).
- Output Connections: Connect your passive speakers to the amplifier's output terminals. Ensure correct polarity (+ to + and - to -) for each speaker. The A800 supports both stereo and bridged mono operation. Refer to the rear panel diagram (not shown in image, but implied) for specific output configurations.
- Grounding: For optimal performance and to minimize hum, ensure all connected equipment is properly grounded.
Operating Instructions
Once properly set up, the Behringer A800 is ready for operation. Follow these guidelines for safe and effective use.
- Power On/Off: After all connections are made, switch on your audio source first, then power on the A800. When powering down, switch off the A800 first, then your audio source.
- Volume Control: Use the dedicated volume knobs for Channel A and Channel B to adjust the output level. Start with the volume at its minimum setting and gradually increase to the desired listening level.
- LED Metering: The central LED display provides real-time visual feedback on signal levels. Green LEDs indicate signal presence, while red LEDs (CLIP) indicate signal clipping, which should be avoided to prevent distortion and potential speaker damage. The PROT LED indicates protection mode.
- Stereo and Bridged Mono Operation: The A800 can operate in stereo mode (two independent channels) or bridged mono mode (combining both channels for higher power output to a single speaker). Consult the rear panel markings and the full technical specifications for details on switching modes.
- Overload Protection: The amplifier features built-in overload protection circuitry to safeguard itself and connected speakers from excessive signal levels.
- Convection Cooling: The A800 utilizes convection cooling, meaning it does not have internal fans. Ensure adequate airflow around the unit to prevent overheating.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your Behringer A800 Power Amplifier.
- Cleaning: Disconnect the amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Avoid using abrasive cleaners, solvents, or waxes, as they can damage the finish.
- Ventilation: Ensure that the ventilation openings on the amplifier are not blocked. As the A800 uses convection cooling, proper airflow is essential to dissipate heat. Do not place the unit in an enclosed space without adequate ventilation.
- Storage: If storing the amplifier for an extended period, keep it in a cool, dry place, away from direct sunlight and extreme temperatures.
- Cable Inspection: Periodically inspect all audio and power cables for any signs of wear or damage. Replace damaged cables immediately.
