CONTROLS AND FUNCTIONS
Bass Pro has controls and indicators
that help simplify sonic integration with
almost any vehicle’s unique acoustic
properties. These controls are located
on the amplifier panel, as shown in
Figure 10
.

POWER LED:
This indicator
will glow red when the BassPro is
operating.
GAIN CONTROL:
Use this
control to adjust the relative volume
(loudness) of BassPro with the other
speakers in the vehicle.
CROSSOVER:
Use this control to
adjust the amount of high-frequency
information present in BassPro’s output.
A lower value signifies less high-
frequency content.
3. Turn the head unit ON and play a
selection of your favorite music track
that has substantial bass.
4. Adjust the CROSSOVER control
counterclockwise, until you hear only
low-frequency information.
Example – you should not hear vocals
coming from BassPro when seated in
the normal listening position.
5. Adjust the BASS CONTROL either
clockwise or counterclockwise to suit
your taste, and to avoid audible
distortion.
6. If you elect to not install the Remote
Bass Control, adjust the GAIN
control to the maximum level that
provides undistorted output from the
BassPro, with the head unit’s volume
control at its 3 o’clock setting.
Note: In most cases the above steps
will provide you with satisfactory
results. However, the actual process
may require several readjustments of
each control, since the settings
will interact with one another. If
necessary, consult your authorized
JBL car audio dealer for help in tuning
your system.
AUTO TURN-ON:
For speaker-
level connections, used this switch to
activate (or deactivate) BassPro’s
automatic turn-on circuit. For most
speaker-level applications, slide the
switch to the AUTO position. If you
prefer to use the remote (REM)
connection, slide the switch to the OFF
position.
REMOTE BASS CONTROL:
Use this RJ-11 jack to connect the
supplied remote bass control.
SETTING THE CONTROLS:
1. Make sure the head unit is off and
volume control is set to minimum.
2. On BassPro’s amplifier panel, set the
Crossover to its maximum
frequency of 120Hz, as shown in
Figure 10
.
Note: If using the REMOTE BASS
CONTROL, set GAIN to maximum and
set the BASS CONTROL to the
midpoint.
