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 wear adequate hearing protection if
listening at high volume levels, as continued exposure to high sound pressure levels can cause permanent hearing impairment or loss.

Speakers are bridged with the Crestron Avia™ Audio tool, which can be downloaded from www.crestron.com/software. The possible bridging
combinations are Output 1 & Output 2, Output 3 & Output 4, Output 5 & Output 6, and Output 7 and Output 8.
