Three Channel (Channel 1, Channel 2, Bridged)
Left and Right are configured for two-channel stereo operation.•
Lowest recommended impedance is 2• Ω stereo.
The third output is configured for a single channel bridged out-•
put.
The bridged outputs lowest recommended impedance is 4• Ω.
Outputs are configured for high-pass, low-pass, or full range •
operation.

NOTE: To get full output in this configuration, band limiting filters as
shown in this diagram may need to be used to prevent the impedance
from dropping too low and engaging protection circuits.
