The 5761a can be configured for 6-channel,
5-channel or 3-channel operation, as shown
in Figures 10 through 12.
INPUT MODE SWITCH:
• Use INT (internal mode) to send a signal from
the front and rear inputs to the subwoofer.
• Use EXT (external mode) when sending a
dedicated signal to the subwoofer inputs; e.g.,
if your source unit has a subwoofer output.
NOTE: For simplicity, Figures 10 through 12 do
not show power, remote and input connections.
NOTE: Minimum speaker impedance for
stereo operation is 2 ohms. Minimum speaker
impedance for bridged operation is 4 ohms.
APPLICATIONS – 5761a
Figure 10. 6-Channel operation: 5761a amplifier driving full-range front and rear speakers and a pair of subwoofers.
Figure 11. 5-Channel operation: The same as Figure 10, with the subwoofer output bridged to drive a single 4-ohm subwoofer, providing
the speaker with more power.
Figure 12. 3-Channel operation: 5761a amplifier configured for 3-channel operation, where all of the channels are bridged for a
subwoofer and a pair of component speak
