Frequently Asked Questions [+]

The fan in my speaker is not spinning, is something wrong? Should the fans in both of my speakers operate exactly the same?
The fan operates as needed to control the internal temperature of the amplifier. There are component tolerances which cause small variations from unit to unit. It is normal for a unit at room temperature to have the fan spin slowly, or not at all, or to stop and start. It is normal for this to vary slightly from unit to unit. It has no impact on the performance of the product.
