What amplifier class is the AXR85/100?
The AXR85 and AXR100 use class AB amplification.
Can I use 4 or 6 Ohm speakers with the AXR85/100?
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.
