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 oper-
ation, 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 opera-
tion is 4 ohms.
