Yes, the Yamaha AX-630 Amplifier supports two pairs of speakers. You can switch between or use both pairs simultaneously using the A/B speaker selectors. Ensure the impedance of the speakers is within the amplifier's supported range.
To clean the Yamaha AX-630, unplug it and use a dry, soft cloth to wipe the exterior. Avoid using any liquid or aerosol cleaners. Regularly check and clean the cable connections to maintain optimal performance.
Overheating can occur due to poor ventilation. Ensure the amplifier is placed in a well-ventilated area and not stacked with other equipment. Keep the vents clear of dust and debris.
