Figure 5. Typical Bridged Output
Configuration
Channel pairs 1-2, 3-4, 5-6, and 7-8 may be bridged in a one-channel
input/two-channel output configuration for a maximum of 50 watts of
output power— into 8 Ohms—per bridged channel pair. Ensure that the
Molex plug is in the 8 Ohm receptacle for each bridged pair.
Figure 5 (below) shows a balanced input/bridged output configuration.
After you make the appropriate connections for bridging both channels,
insert the Molex plug into the 8 Ohm receptacle and slide the bridge
switch for the channel pair to the right (ON). The amber LED next to the
switch will indicate that bridging is active.
