Remote Level Control
Requires HD-RLC controller (sold separately).
Multiple amplifiers can be controlled with
one controller by adding standard phone
cable splitter (not included). This is a true
subwoofer level control, not a “bass boost”.
Output Polarity:
Carefully listen to the sub-bass to mid-bass transition with music
that has strong mid-bass content. Select the switch position
which gives the smoothest, most natural mid-bass response. If
using multiple HD750/1’s on multiple subwoofers, make sure this
switch is set to the same position on all amplifiers.
Infrasonic Filter:
Turn “Off” for Sealed Enclosure.
Select “30Hz” for Ported Enclosure.
Input Sensitivity Controls:
Proper adjustment of
these controls is critical!
For virtually all aftermarket
head units, set “Input
Voltage” to “Low”. See
“Input Sensitivity Setting
Guide” on pg. 14 for precise
setting instructions.
Filter Mode & Slope:
Set “Mode” switch to
“LP”. Set “Slope” switch to
“24dB”. Set “Filter Freq.
(Hz)” knob to “85”.
Lower settings are likely to
result in a poor transition
between the upper
response of the W7AE and
the lower response of the
mid-bass speakers.
JL Audio HD750/1:
These settings are intended as a
“baseline” for tuning your system.
Depending on your vehicle and
your preferences, some variation
in the crossover and bass control
settings may be necessary for
optimum performance.
