About This Manual
To attain maximum amplifier perfor-
mance, we encourage you to read the
remaining pages before installing and
operating your new JBL Power Series
amplifier. Especially review the
Applications section for ideas on design-
ing and expanding your system. Also,
save these instructions for future refer-
ence. Installation of automo-Important:
tive stereo components can require
extensive experience in performing a
variety of electrical and mechanical pro-
cedures. Although these instructions
explain how to install a JBL Power Series
amplifier in a general sense, they do not
show the exact installation methods for
your particular vehicle. If you do not have
the experience, do not attempt the instal-
lation yourself; instead ask your
Authorized JBL Car-Audio Dealer about
professional installation options.
Installation Precautions and Notes
The JBL Power Series amplifiers have
five levels of circuit protection that moni-
tor the amplifiers and will shut them
down if the electrical-system voltage
drops below 5Vdc or exceeds 18Vdc, tem-
peratures are above 194° F (90° C), short
circuits occur or current draw exceeds
product specifications. For best perfor-
mance, check the intended mounting site
to make sure the operating environment
does not create conditions that will trig-
ger circuit protection.
• Prior to installation, turn off all audio
systems and other electrical devices.
Also disconnect the (–) negative lead
from the vehicle’s battery.
• At the installation site, locate and make
a note of all fuel lines, hydraulic brake
lines and electrical wiring. Use extreme
caution when cutting or drilling in and
around these areas.
• Check clearances on both sides of a
planned mounting surface before
drilling any holes or installing any
screws. Remember that mounting
screws can extend behind the mount-
ing surface.
Thank you for purchasing your new
JBL Power Series™ amplifier. Power
Series amplifiers feature the latest
advances in discrete-circuit topology,
ensuring low distortion and superbly
clean and clear sound quality. In addition
to RCA-type pre-amp inputs, Power
Series amplifiers feature Universal
Interface™, designed to facilitate integra-
tion with factory-installed audio systems
for distortion-free performance that rivals
conventional pre-amp connections.
Included in the Universal Interface circuit
is Common Sense™ turn-on. Common
Sense turn-on senses the common-mode
voltage present on the speaker outputs of
factory and aftermarket radios, turning on
the amplifier without a separate remote
wire. All Power Series amplifiers feature
built-in electronic crossovers and pre-
amp outputs for easy system expansion
without requiring outboard processors.

• Always wear protective eyewear when
using tools.
• When routing cables, keep input signal
cables away from power cables and
speaker wires.
• When making connections, make sure
that each connection is clean, insulated
and properly secured. Observe the
polarity markings on the rear panel.
Refer to the application drawings to set
up the amplifier for operation in stereo,
bridged-mono, bi-amp or tri-mode con-
figurations.
• If the amplifier’s fuse must be replaced,
use only the same rating and type as a
replacement. Do not substitute another
kind.
Controls and Connectors
1. Pre-amp Level Input Connector –
Connects to line-level output from the
source unit.
2. Universal Interface Speaker Level
Connector – Connects to speaker-level
output from the source unit. Provides
Common Sense amplifier turn-on
when used with factory radios
(2-channel on P-7520, 4-channel on
P-7540).
3. Pre-amp Level Output Connector –
Connects to other amps or processors
in the signal chain.
4. Speaker-Output Connector – (2-chan-
nel on P-7520, 4-channel on P-7540).
5. Fuses – P-7520: 30A ATC type, P-7540:
30A ATC type x 2, P-2510: 40A ATC
type.
6. Power Connector – Connection for
12V+, Gnd and Rem.
7. Input-Mode Switch – Sums left and
right inputs.
8. Input Sensitivity Control – Adjusts
input sensitivity for pre-amp level and
speaker-level inputs.
9. Pre-amp Output Selector Switch –
Selects input path for pre-amp output.
Output can be summed from front and
rear inputs with no filter, or filtered by
the front or rear crossover.
10. Rear-Channel Input Selector – Selects
rear-channel input between front input
and rear input.
11. Crossover Selector – Determines
whether the crossover is a High-Pass
filter (HP), Low-Pass filter (LP) or
unfiltered (flat).
12. Crossover Frequency Control –
Determines the crossover frequency
for the amplifier channels (front or
rear) and the pre-amp outputs.
