• For the "Speaker Input Level System" setting, connecting the Remote Turn-On Lead is not required due to
the "REMOTE SENSING" function of this product. However, the "REMOTE SENSING" function may not work
depending on the signal source connected. In such a case, connect the Remote Turn-On Lead to an
incoming power supply cord (accessory power) in the ACC position.

line output is used to drive both inputs of the bridged amp.
