JBL GTO75.2, GTO1201.1, GTO601.1, GTO301.1, GTO75.4 APPLICATIONS - GTO755.6, INPUT MODE switch

APPLICATIONS – GTO755.6

The GTO755.6 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.
