Speaker Connections
The speaker outputs can be wired conventionally, or they can be bridged to deliver higher power to a speaker. Refer to the following diagrams when
connecting speakers.
WARNING: This amplifier is capable of delivering high power to the loudspeakers. Please use caution and adequate ear protection if listening to content at
high volume levels, as continued exposure to high sound pressure levels can cause permanent hearing impairment or loss.
