Input Connections
Connect your audio sources (microphones, line-level devices) to the appropriate input jacks on the amplifier. Refer to the rear panel for specific input types and labels.
Output Connections
Connect your loudspeakers to the amplifier's output terminals. Ensure correct polarity (+ to + and - to -) for all speaker connections. Incorrect wiring can lead to poor sound quality or damage to the equipment. The output connector type is RCA.
4. Operating Instructions
Powering On/Off
To power on the unit, press the power switch located on the front panel. The power indicator light will illuminate. To power off, press the switch again.
Adjusting Input Levels
Each input channel has a dedicated level control knob on the front panel. Rotate these knobs clockwise to increase the input volume and counter-clockwise to decrease it. Adjust each input to an appropriate level to prevent distortion.
Master Volume Control
