Each model includes a 12dB-per-octave variable
electronic crossover, with the subwoofer amplifiers
offering the JBL Dynamic Bass Optimization Circuit
and an included remote bass-level control that allows
the bass output to be independently adjusted.

speaker connection to the amplifier, eliminating the
need for adapters or special fittings.
FULL-RANGE PREAMP OUTPUTS
In the event that multiple amplifiers are used in an
application, this feature allows for streamlined
system hookup – no high-loss Y-adapters or splitters
are needed.
COMMON-DIMENSION
AMPLIFIER FOOTPRINTS
By designing the GTO Series amplifiers
with two common dimensions, the amount
of space occupied in multiple-amplifier
mounting applications can be optimized.
DYNAMIC BASS OPTIMIZATION
CIRCUIT (DBO)
This provides variable high-pass filtering with
adjustable “Q” below 100Hz (far beyond conventional
bass circuits) by allowing the low-frequency output
to be optimized for specific subwoofer applications.
Frequencies below an enclosure’s tuned frequency
can be attenuated, preventing damage to the
subwoofer and allowing the amplifier’s power
to be better utilized.
