IMPEDANCE SELECTOR switch

Do not change the IMPEDANCE SELECTOR switch 

while the power of this unit is turned on, as doing so may 

damage the unit.

If this unit fails to turn on, the IMPEDANCE SELECTOR 

switch may not be fully slid to either position. If this is the 

case, slide the switch all the way to either position when 

this unit’s power supply is completely cut off.

Select the switch position (left or right) according to the 

impedance of the speakers in your system.
