APPLICATIONS – GTO755.6
II
The GTO755.6
II
can be configured for
6-channel, 5-channel or 3-channel
operation, as shown in
Figures 9
through 11
.
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 9 through
11 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.

5-Channel operation: The same as Figure 9, with the subwoofer output bridged to drive a single 4-ohm subwoofer,
providing the speaker with more power.

amplifier configured for 3-channel operation, where all of the channels are
bridged for a subwoofer and a pair of component speakers.
