Product Description - JL Audio HD750/1 Owner's Manual

Product descriPtion

The JL Audio HD750/1 is a very powerful
and compact monoblock (single channel),
full-range amplifier utilizing patented Single
Cycle Control™ Class D technology. This
groundbreaking technology delivers reference-
grade sonic performance while requiring
far less current from the vehicle's electrical
system than a conventional amplifier.
Unlike most monoblock amplifiers, the
HD750/1 is a full-range design, so it can be
used as a subwoofer amplifier or as a very
powerful full-range or satellite amplifier,
using a second 750/1 to form a stereo pair.
JL Audio's exclusive R.I.P.S. power supply
design optimizes the output the amplifier for any
impedance between 1.5 and 4 ohms, allowing
you to get full use of the HD750/1's performance
capabilities with a wide range of speaker systems.
The tightly regulated power supply design also
means that the HD750/1's clean power output
capability remains stable over a wide range of
vehicle voltages, resulting in enhanced fidelity.
A flexible input and crossover section permits
operation with a wide variety of source units
and system configurations. The HD750/1's
preamp output can send pass-through signals
from the inputs to feed additional amplifier(s).
