JBL GTO755.6, GTO75.4 Applications GTO301.1, GTO601.1 and GTO1201.1, Applications GTO75.2

APPLICATIONS – GTO301.1, GTO601.1 AND GTO1201.1

The GTO subwoofer amplifiers are single-channel amplifiers. There are two sets of terminals to make it easy to connect multiple woofers. Either set of (+/–) terminals may be used when connecting woofers.

To the right are two application diagrams to help plan your subwoofer system installation. Figures 2 and 3 show how to configure the GTO subwoofer amplifiers (models GTO301.1, GTO601.1 and GTO1201.1).

NOTE: For simplicity, Figures 2 and 3 do not show power, remote and input connections.

NOTE: Minimum speaker load is 2 ohms.

APPLICATIONS – GTO75.2

The JBL GTO75.2 amplifier can be set up for stereo or bridged-mono operation, as shown in Figures 4 and 5.

NOTE: For simplicity, Figures 4 and 5 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.
