What amplifier class is the AXR100D?
The AXR100D uses class AB amplification.
Can I use 4 or 6 Ohm speakers with the AXR100D?
You can use a pair of 4 or 6-ohm speakers, but we do not recommend using two pairs of 4 or 6-ohm speakers with the AXR as this could result in the amplifier overheating, which in the long run could damage the unit.
