PRODUCT DESCRIPTION
The
JL
Audio HD600/4
is
avery powerful
and
compact four-channel, full-range amplifier
utilizing patented Single Cycle Control'"
Class Dtechnology for all channels. This
groundbreaking technology delivers reference-
grade sonic performance while requiring
far less current from the vehicle's electrical
system than aconventional amplifier.
JL
Audio's exclusive RJ.P.S. power supply
design optimizes the output
of
each channel pair
for any impedance between
1.5
and 4ohms per
channel (3-8 ohms bridged) allowing you to get
full use
of
the HD600/4's performance capabilities
with awide range
of
speaker systems.
The tightly regulated power supply design also
means that the HD600/4's clean power output
capability remains stable over awide range
of
vehicle voltages, resulting in enhanced fidelity.
The HD600/4 flexible, studio-grade signal
processing allows it to be deployed in awide
range
of
system applications:
I)
As afour-channel (150W x
4)
full-range
amplifier, delivering full-range signals to two
separate stereo speaker systems (front and rear,
for example).
2)
As
apowerful
(150W
x
4)
four-channel satellite
amplifier in abi-amplified system, delivering
high-passed signals to front and rear speaker
systems. Preamp outputs permit connection
of
a
separate amplifier to drive the subwoofer system.
3)
As
a600W full-system amplifier in
bi-amplified mode with one channel pair
driving subwoofers in low-pass mode (l50W
x 2
or
300W x
I)
and the other channel pair
driving main speakers in high-pass mode
(150W x
2).
4)
As
avery powerful (300W x
2)
full-range
amplifier, delivering full-range signals to a
stereo speaker system.

5)
As
avery powerful (300W x
2)
two-channel
satellite amplifier in abi-amplified system,
delivering high-passed signals to astereo
speaker system. Preamp outputs permit
connection
of
aseparate amplifier to drive the
subwoofer system.
6)
As
apowerful (300W x
2)
two-channel
subwoofer amplifier in abi-amplified system,
delivering low-passed signals to adual
subwoofer system. Preamp outputs permit
connection
of
aseparate amplifier to drive the
satellite speakers.
The HD600/4's flexible input and crossover
sections permit operation with awide variety
of
source units and system configurations. It can be
operated with asingle pair
of
stereo inputs or with
separate inputs for its front and rear channels.
The HD600/4's preamp output can send pass-
through signals from the Front Inputs only or
it
can sum all four input channels to feed anon-
fading signal to aseparate subwoofer amplifier.
As
we
said, it's very flexible.
