• 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.
Important Tips on Bridging an Amplifier
Low output will result if only one channel input is used. The Y-adapter is not required if a stereo/mono pair
line output is used to drive both inputs of the bridged amp.
