PRODUCT DESCRIPTION

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence for a

typical amplifier installation, using an aftermarket

source unit. Additional steps and different

procedures may be required in some applications.

If you have any questions, please contact your

authorized JLAudio dealer for assistance.

The JL Audio 500/5 is a five-channel system

amplifier utilizing patented Absolute Symmetry™

Class AB technology for its front and rear channels

and patented Class D technology for its subwoofer

channel. Front and subwoofer channels benefit from

JL Audio's exclusive R.I.P.S. power supply design

which optimizes the output of each section for any

impedance between 1.5 and 4 ohms per channel.

The staggered power distribution of the front

and rear channel pairs (100W x 2 for front and

25 x 2 for rear) allows for a wide variety of

application options.The 500/5 can be operated in

the following modes:

1) As a full-system amplifier in bi-amp mode with

its subwoofer channel driving subwoofers in low-

pass mode (250W x 1), front channels driving front

component speakers (100W x 2) in high-pass

mode and rear channels driving rear component

speakers in high-pass mode (25W x 2).

2) As a full-system amplifier in a tri-amplified

system, delivering band-passed signals through its

front channels to mid-bass/mid-range speakers and

high-passed signals through its front channels to

tweeters.

The 500/5's flexible input and crossover sections

permit operation with a wide variety of source units

and system configurations.The 500/5 can operate

with a single pair of stereo inputs or with separate

inputs for front and rear channel pairs, if the source

unit is equipped with front and rear outputs.The

subwoofer channel can be driven with a discrete

signal from a source unit’s subwoofer output or can

receive its signal from the front and/or rear channel

inputs.

12) Carefully review the amplifier’s control

settings to make sure that they are set according to

the needs of the system.

13) Install power wire fuse (50A for a

single 500/5) and reconnect the negative

battery post terminal.

14) Turn on the source unit at a low level

to double-check that the amplifier is configured

correctly. Resist the temptation to crank it up until

you have verified the control settings.

15) Make necessary adjustments to the input

sensitivity controls of the subwoofer channel and

front and rear channel pairs to obtain the right

overall output and the desired balance between

their outputs. See Appendix B (page 22) for the

recommended input sensitivity setting method.

16) Enjoy the fruits of your labor with your

favorite music.

To connect the power wires to the amplifier, first

back out the set screw on the top of the amplifier,

using the supplied 2.5 mm hex wrench. Strip

1/2 inch (12 mm) of insulation from the end of

each wire and insert the bare wire into the

receptacle on the front panel of the amplifier, seating

it firmly so that no bare wire is exposed.While

holding the wire in place, tighten the set screw

firmly, taking care not to strip the head of the screw.

The ground connection should be made using

the same gauge wire as the power connection

(4 AWG) and should be kept as short as possible,

while accessing a solid piece of sheet metal in the

vehicle.The surface of the sheet metal should be

sanded at the contact point to create a clean, metal-

to-metal connection between the chassis and the

termination of the ground wire.The use of a star

washer to lock down the connection is advisable.

Any wires run through metal barriers (such as

firewalls), must be protected with a high quality

rubber grommet to prevent damage to the

insulation of the wire. Failure to do so may result in

a dangerous short circuit.

1) Disconnect the negative battery post

connection and secure the disconnected cable to

prevent accidental re-connection during installation.

This step is not optional!

2) Run power wire (minimum 4 AWG) from

the battery location to the amplifier mounting

location, taking care to route it in such a way that

it will not be damaged and will not interfere with

vehicle operation. Use 2 AWG or 1/0 AWG

power wire if additional amplifiers are being

installed with the 500/5.

3) Connect power wire to the positive battery

post. Fuse the wire with an appropriate fuse block

(and connectors) within 18 inches (45 cm) wire

length of the positive battery post. This fuse is

essential to protect the vehicle. Do not install the

fuse until the power wire has been connected to

the amplifier.

4) Run signal cables (RCA cables) and remote

turn-on wire from the source unit to the amplifier

mounting location.There are several ways to provide

input to the 500/5. Please read the rest of this manual

carefully to choose the best one for your system.

5) Run speaker wire from the speaker systems to

the amplifier mounting location.

POWER CONNECTIONS

Before installing the amplifier, disconnect the

negative (ground) wire from the vehicle's battery.

This will prevent accidental damage to the system,

the vehicle and your body during installation.

IMPORTANT

+12VDC

Ground Remote

Many vehicles employ small (10 AWG - 6 AWG)

wire to ground the battery to the vehicle chassis and

to connect the alternator's positive connection to the

battery.To prevent voltage drops, these wires should

be upgraded to 4 AWG when installing amplifier

systems with main fuse ratings above 60A.

JL AUDIO 500/5

five-channel system amplifier

6) Find a good, solid metal grounding point close

to the amplifier and connect the negative power wire

to it using appropriate hardware. Use 4 AWG power

wire, no longer than 36 inches (90 cm) from the

amplifier to the ground connection point. In some

vehicles, it may be necessary to upgrade the battery

ground wire. (See page 5 for important notice).

7) Securely mount the amplifier using the

supplied screws.

FUSE REQUIREMENTS

The 500/5's “+12VDC” and “Ground”

connections are designed to accept 4 AWG power

wire. 4 AWG is the only recommended

power wire size for this amplifier.

It is absolutely vital that the main power wire(s)

to the amplifier(s) in the system be fused within

18 inches (45 cm) of the positive battery post

connection.The fuse value at each power wire

should be high enough for all of the equipment

being run from that power wire. If only the

500/5 is being run from that power wire, we

recommend a 50A fuse be used. AGU (big glass

fuse) or MaxiFuse™ (big plastic-body fuse) types

are recommended.

The 500/5's preamp output can send pass-

through signals from the front inputs only, the

subwoofer inputs only OR a sum of the front and

rear input signals.This allows the connection of

additional subwoofer amplifier(s) or full-range

amplifiers.

If you are installing the 500/5 with other

amplifiers and wish to use a single main power wire,

use 2 AWG or 1/0 AWG main power wire

(depending on the overall current demands of all

the amplifiers in the system).This 2 AWG or 1/0

AWG power wire should terminate into a

distribution block mounted as close to the amplifiers

as possible and should connect to the 500/5 with

4 AWGpower wire.

8) Connect the positive and negative power

wires to the amplifier.A fuse near the amplifier is

not necessary.

9) Connect the remote turn-on wire

to the amplifier.

10) Connect the RCA input cables

to the amplifier.

11) Connect the speaker wires to the amplifier.

No fuse is required or recommended directly

before the amplifier power connection. If one is

desired, we recommend the use of a 50A AGU fuse

or MaxiFuse™ type.

Please note that smaller AWG numbers mean

bigger wire and vice-versa (1/0 AWG is biggest, 2

AWG is smaller, then 4 AWG, then 8 AWG, etc.).

TURN-ON LEAD

CROSSOVER CONTROLS

The 500/5 uses a conventional +12V remote

turn-on lead, typically controlled by the source unit's

remote turn-on output.The amplifier will turn on

when +12V is present at its “Remote” input and

turn off when +12V is switched off. If a source unit

does not have a dedicated remote turn-on output,

the amplifier’s turn-on lead can be connected to

+12V via a switch that derives power from an

ignition-switched circuit.

The 500/5's “Remote” turn-on connector is

designed to accept 18 AWG – 8 AWG wire. 12

AWG is more than adequate for this purpose.

To connect the remote turn-on wire to the

amplifier, first back out the set screw on the top of

the amplifier, using the supplied hex wrench. Strip

1/2 inch (12mm) of wire and insert the bare wire

into the receptacle on the front panel of the

amplifier, seating it firmly so that no bare wire is

exposed.When using smaller wire, it may be

necessary to strip 1 inch of insulation from the wire

and fold the bare wire in half prior to insertion.

While holding the wire in the terminal, tighten the

set screw firmly, taking care not to strip the head of

the screw and making sure that the wire is firmly

gripped by the set screw.

rotary control will operate within that window. If

you are using an aftermarket source unit, with

conventional preamp-level outputs, this is most likely

the position that you will use.

The “High” position on each “InputVoltage”

switch selects an input sensitivity range between

800mV and 8V.This is useful for certain high-output

preamp level signals as well as speaker-level output

from source units and small amplifiers.To use

speaker-level sources, splice the speaker output

wires of the source unit or small amplifier onto a

pair of RCA plugs.

Crossovers are groups of individual electronic filters

which allow only certain frequency ranges to pass

through them by attenuating frequencies outside

the selected range.These filters allow the user to

specify what frequency range will be sent out of

each channel section of the amplifier.This, in turn,

allows each speaker system to only reproduce a

range of frequencies it is well-suited for, resulting in

reduced distortion and improved fidelity.

1) “Filter Mode” Control: Located in the “Front

Filter Section”, this switch allows you to configure

the Front Channel filter into one of three modes:

“Off” (Defeated): Defeats the filter for the Front

Channels completely, allowing the full range of

frequencies present at the inputs to feed that pair

of channels.This is useful for systems utilizing

outboard crossovers or requiring full-range

reproduction from these channels.

“BP” (Bandpass): Configures the Front Channel

Filter to attenuate frequencies above the selected

filter frequency and below the frequency selected in

the Rear Channel High-Pass Filter. This creates a

true bandpass filter well-suited for driving mid-bass

or mid-range speakers in a tri-amplified system (see

page 18 for details).

“HP” (High-Pass): Configures the Front Channel

Filter to attenuate frequencies below the selected filter

frequency. Useful for connection of component

speakers to the front channels in a bi-amplified system.

2) “Filter Slope” Control: This switch allows you

to select from two filter slopes.

“12dB”: Configures the Front Channel Filter to

attenuate frequencies below the selected filter

frequency at a rate of 12 dB per octave

Input Sensitivity Adjustment:

Front and Rear Channel “Input Mode” Selection:

Located to the right of the rear channel input

jacks in the “Rear Input Section” is a switch

labeled “F/R Input Mode”.This switch determines

whether the front and rear channels will receive

their input independently (select “4ch”) or from

the “Rear Input Section”jacks only (select “2ch”).

Located next to the “InputVoltage” switch in

each input section is a rotary control labeled “Input

Sens.” Once the appropriate “InputVoltage” range

has been selected, this control can be used to

match up the signal level of the system to produce

the desired level from the amplifier. Rotating the

control clockwise will result in higher sensitivity

(louder for a given input voltage). Rotating the

control counter-clockwise will result in lower

sensitivity (quieter for a given input voltage.) Be

aware that each of the three “Input Sens.”

adjustments will have to be made, regardless of

how many inputs are feeding the amplifier.These

controls will allow you to set the appropriate

relative levels for the subwoofer channels and the

front and rear channels.

INPUT SECTIONS

Three left/right pairs of RCA type jacks are

provided for input (one pair for the subwoofer

channel, one pair for the rear channels and one pair

for the front channels).There are several ways that

the 500/5's inputs can be configured. Please read the

“System Configurations” section of this manual (page

14) carefully to determine the proper configuration

for your application.

InputVoltage Range:

A wide range of signal input voltages can be

accommodated by each of the 500/5's input stages

(200mV – 8V).This wide range is split up into two

sub-ranges, accessible via switches located in each

input section of the amplifier. Be aware that

each input section's “InputVoltage” switch

will have to be configured, regardless of

how many inputs are actually feeding the

amplifier.

IMPORTANT

To properly set each set of amplifier channels

for maximum clean output, please refer to

Appendix B (page 22) in this manual. After using

this procedure, you can then adjust the relative

level of each channel pair by adjusting the input

sensitivity downward on either or both channel

pairs, if they require attenuation to achieve the

desired system balance.

vehicle, different filter slopes may be required to

produce a smooth transition between the sound of

different speakers in the system. Experiment to find

the slope which best matches the acoustic

benefits from the 12 dB per octave slope which lets

more upper bass content pass through.A sub that

fires directly into the listening environment is more

likely to benefit from a 24 dB per octave slope.

The above hint is not a “set-in-stone” rule…You

should always listen to the system carefully to

determine the best choice as vehicle acoustics and

other factors play a big role in choosing the most

appropriate filter slope.

this manual (page 20).

The 500/5's subwoofer channel filter (located in

the “Subwoofer Channel Control Section”

employs an advanced state-variable, low-pass active

filter. This feature is designed to attenuate

frequencies above its filter frequency, so that the

system's subwoofers do not reproduce any audible

midrange content.The low-pass filter in the 500/5 is

fully variable between 40 Hz and 200 Hz via the

“Filter Freq.” control knob and features the ability

to select between a moderate “12dB” per octave

or a steep “24dB” per octave slope.

“LF Boost” or “Infrasonic Filter” processing

selected for the amplifier.When the 500/5 is being

used to drive front, rear and subwoofer speaker

systems, this preamp output mode will deliver a

summed front/rear signal to an additional

subwoofer amplifier, while permitting fading of the

front and rear speaker systems from the source

unit.

3) “Front”: This is a pass-through mode for the

preamp output, delivering the same signal that is

being fed to the “Front Input Section” of the

amplifier (If the input signal is full-range, the preamp

output will be full-range.)This signal is not affected

by the “LF Boost” or “Infrasonic Filter” processing

selected for the amplifier.

The 500/5's subwoofer channel control section

also includes some basic bass processing tools.

These consist of two primary components: a

fixed-frequency, 24 dB / octave infrasonic filter and

a fixed-frequency / “Q”, single-band equalizer

centered at 48 Hz.

the “12dB” or “24dB” position.These features will

not work with the “Sub LP Filter” switch in the

“Off” position.This is to prevent cascading the

processing of multiple amplifiers when configured in

a master / slave arrangement. If you are using an

external active crossover and would like to use the

“LF Boost” and “Infrasonic Filter” features, set the

“Amp LP Filter” switch on “12dB” and rotate the

frequency selection knob fully clockwise to the “200

Hz” position.This will activate the bass processing

features without significantly affecting the crossover

point selected by the external active crossover.

If you connect a load higher than 4Ω nominal

per channel (or 8Ω in bridged mode for the front

and rear channels), power will drop by half with

every doubling of impedance above 4Ω stereo /

8Ω mono. If you connect a load lower than 1.5Ω

nominal per channel, the amplifier protection

circuitry activates a “safe” mode which reduces

amplifier power to protect the circuitry from

failure (the yellow “Low Ω” LED lights to indicate

that this has happened). See page 12 for details.

Speaker loads below 1.5Ω nominal per channel

are not recommended and may cause the amplifier

output to distort excessively.

IMPORTANT

1) “Infrasonic Filter”:The infrasonic filter is a

24 dB / octave high-pass filter, with a fixed cutoff

frequency of 30 Hz.This filter is designed to

conserve amplifier power and protect subwoofer

systems without audibly degrading the sub-bass

output.With ported enclosures, the use of the

infrasonic filter is highly recommended to protect

the speaker(s) from excessive excursion below box

tuning.With sealed enclosures, the use of the filter is

less necessary, but can still help protect the speaker

system.The infrasonic filter can be completely

defeated by selecting the “Off” position on the

“Infrasonic Filter” switch.This bypasses all signal

from flowing through the circuit.

2) LF (Low-frequency) Boost: This feature

allows the user to control the boost of a fixed “Q”,

fixed-frequency equalization band centered at 48

Hz.The “LF Boost” rotary control determines how

much boost (in dB) you are adding to the bass

signal.A range of 0-15 dB of boost is available. If no

boost is desired, rotate the “LF Boost” control fully

counterclockwise.

Regulated, Intelligent Power Supply (R.I.P.S.) design

on its front and subwoofer channels.The operation

of the R.I.P.S. system is independent for each pair of

channels.This sophisticated power supply allows the

amplifier to produce its optimum power (100 watts

x 2 for the front channels and 250 W x 1 for the

subwoofer channel over a wide range of speaker

impedances. Unlike conventional amplifiers that

require a specific impedance to produce optimum

power, the R.I.P.S.-equipped 500/5 gives you the

freedom to use a variety of speaker configurations

that achieve final nominal impedances between 1.5

– 4Ω per channel (without sacrificing power output

or sound quality).When bridged, the front channel

pair will optimize output between 3 – 8Ω.The rear

channel pair will optimize output between 6 - 8Ω.

The operation of the R.I.P.S. circuitry is entirely

automatic and adjusts itself every time the amplifier

is turned on according to the lowest impedance

present at the speaker load.There are no user

controls to configure.The system operates through

multiple stages of impedance optimization, choosing

the stage most appropriate to the actual impedance

of the speakers you connect to it.

The rear channels of the 500/5 do not employ

R.I.P.S. optimization and are designed to deliver rated

power into loads between 3 and 4Ω per channel.

Operating the rear channels below 3Ω may result in

excessive distortion and/or shutting down of these

channels and is not recommended.

CAUTION

If the “Output Mode” switch is in the “Sub LP”

position and the “Sub LP Filter” switch is in the

“Off” position, the preamp output will be a

12dB/octave low-pass with the “Bass Control”

processing added to it. THIS IS NOT A

PREFERRED OPERATING MODE. DO NOT

USE THIS MODE FOR MASTER / SLAVE

CONFIGURATIONS.

Note:The signal level of the “Preamp Output” is

affected by the setting of the “InputVoltage”

switches (of the input section(s) chosen by the

“Signal From” switch). See the “InputVoltage

Range” section (page 6) for details on input voltage

settings.The preamp output level is not affected by

the “Input Sens.”rotary controls.

BRIDGING CONSIDERATIONS

Bridging is the practice of combining the output

of two amplifier channels to drive a single load.

When bridged, each channel produces signals of

equal magnitude, but opposite polarity.The

combined output of the two channels provides

twice the output voltage available from a single

channel.The 500/5 has been designed for bridging

of its front and rear channel pairs without the need

that channel pair.This requires an RCA “Y-adaptor”

(not included.) Connection of only one RCA input

will result in reduced power output, increased

distortion and can cause the amplifier to overheat.

Do not do this! Instead, use a “Y-adaptor” to split

the mono signal into both left and right RCA inputs.

Why a mono signal? If you are bridging a pair of

channels and use a stereo input, the only

information that will reach the amplifier stage is the

common-phase portion of the signal.This may be

useful for passively deriving a center-channel signal,

but is not going to give you a defined left or right

channel. If you are looking to reproduce a single

channel’s signal, you must split the mono signal with

a “Y-adaptor” and connect it to both left and right

RCA inputs for the bridged channel pair.

PROTECTION CIRCUITRY

There are three status indicator lights on the top

of the amplifier. These are as follows:

SERVICINGYOUR JL AUDIO AMPLIFIER

If your amplifier fails or malfunctions, please

return it to your authorized JL Audio dealer so

that it may be sent in to JL Audio for service.

There are no user serviceable parts or fuses

inside the amplifier.The unique nature of the

circuitry in the JL Audio amplifiers requires

specifically trained service personnel. Do not

attempt to service the amplifier yourself or

through unauthorized repair facilities.This will not

only void the warranty, but may result in the

creation of more problems within the amplifier.

1) “Power” (Green): lights to indicate that the

amplifier is turned on and operating normally.

2) “Thermal” (Red): lights to indicate that the

amplifier has exceeded its safe operating

temperature, putting the amplifier into a self-

protection mode, which reduces the power output

of the amplifier. The red light will shut off and the

amplifier will return to normal, full-power operating

mode if the heat sink temperature drops back to a

safe level.

3) “Low Ω” (Amber): lights to indicate that the

impedance of the speaker load connected to the

amplifier is lower than the optimum load impedance

range for the amplifier.When this light is on, a

protection circuit engages and reduces the power

output of the front or subwoofer channel,

depending on which channel is experiencing the

problem.The amber indicator will also light when a

short-circuit is detected in the speaker wiring (this

can be a short between the positive and negative

speaker wires or between either speaker wire and

the vehicle chassis).This can be used to diagnose a

short-circuit by only connecting one of the amplifier

sections at a time (front, rear and subwoofer).

The amber LED will light when you connect the

section that is experiencing the problem and turn

the volume up.

If you have any questions about the installation or

setup of the amplifier not covered in

this manual, please contact your dealer or the

JL AUDIO Technical Department for assistance:

(954) 443-1100

9:00 AM – 5:30 PM Eastern Time,

Monday – Friday

There is only one condition that will shut

down an undamaged 500/5 completely…

If battery voltage drops below 10 volts, the entire

amplifier will shut itself off.The green “Power”

indicator on the top of the amplifier will turn off

when this occurs.The amplifier will turn back on

when voltage climbs back above 10 volts.This may

happen in a rapid cycle when bass-heavy program

material causes a weak charging system to dip

below 10 volts momentarily. If this is happening in

your system, have your charging system inspected to

make sure it is working properly.A 0.5 or 1.0 Farad

rapid-discharge capacitor connected in parallel to

the amplifier power connections will minimize these

short duration voltage dips in most systems that are

having this problem.

For information on troubleshooting this

amplifier, refer to Appendix D (page 26).

SYSTEM CONFIGURATIONS

STEREO BI-AMP MODE:

This is the most common application for a

5-channel amplifier. In this mode, the front satellite

speakers, rear satellite speakers and subwoofer(s) are

independently powered and filtered. Front and rear

channels each have independent high-pass filters and

the subwoofer channel has an independent low-pass

filter. Left and right front satellite channels deliver

100W x 2 @ 1.5 - 4Ω per channel. Left and right

rear satellite channels deliver 25W x 2 @ 3 - 4Ω per

channel. One mono subwoofer channel delivers

250W x 1 @ 1.5 - 4Ω.

Input Connection Options for the Stereo Bi-Amp

mode are as follows:

can be controlled with the source unit fader,

without affecting the level of the subwoofer channel.

See diagram B below.

Note: This configuration can also be set up so

that the subwoofer level tracks with the front

channel level.To configure the system in this

manner, go to the “Subwoofer Channel Control

Section” / “Input From” selector switch and

select “Front” instead of “F+R”.

C) Two pairs of inputs connected to the rear

and subwoofer inputs of the 500/5 (a source unit

or processor with front and rear outputs is

required). In this mode, the source unit or

processor fader adjusts the relative level of the

subwoofer channel vs. all four satellite channels as

a whole.The relative level of the front and rear

channels is pre-set with the amplifier input

sensitivity controls and cannot be adjusted from

the source unit. See diagram C on page 16.

D)Three pairs of inputs connected to the rear,

front and subwoofer inputs of the 500/5.This mode

is applicable for use in systems with a source unit or

processor that provides discrete front, rear and

subwoofer outputs. In this mode, the subwoofer

level and front to rear fading can be controlled from

the front of the vehicle. See diagram D on page 16.

A) Single pair of inputs connected to the rear

inputs of the 500/5. In this mode, the user has no

fading capability between the front and rear channels

and no separate adjustability of subwoofer level from

the front of the vehicle. See diagram A below.

B)Two pairs of inputs connected to the front and

rear inputs of the 500/5 (a source unit or processor

with front and rear pairs of outputs is required). In

this mode, the user has front-to-rear fading

capability with non-fading sub-bass level.This means

that the relative level of the front and rear satellites

IMPORTANT

Some source units and processors with

• If your sub preamp output has a choice between

full-range and low-pass modes, select the full-

range mode and use the 500/5's (likely more

sophisticated) sub low-pass filter by selecting the

“12dB” or “24dB” position on the “Sub LP

Filter” switch. This configuration is illustrated in

the setup diagram.

• If the source unit/processor sub preamp output

has a low-pass filter which is not defeatable, you

can turn the 500/5's low-pass filter off by going

to the “Subwoofer Channel Control Section” /

“Sub LP Filter” switch and selecting the “Off”

position. Depending on the crossover point and

slope of the source unit/processor's filter, you

may wish to engage the 500/5's sub low-pass

filter to fine-tune the sub-bass response.

• If you are using a high-quality outboard active

crossover, you can defeat all of the 500/5's filters

by selecting the “Off” position on the “Sub LP

Filter” switch in the “Subwoofer Channel

Control Section”, the “High-Pass Filter” switch

in the Rear Filter Section and the “Filter Mode”

switch in the Front Filter Section.

L-R Ambience Control:

subwoofer preamp outputs provide low-pass

filtering on these outputs, while others have a full-

range output. Consult your source unit or processor

owner's manual to determine the properties of the

subwoofer preamp output.

• If your sub preamp output is full-range, engage

the 500/5's sub low-pass filter by selecting the

“12dB” or “24dB” position on the “Sub LP

Filter” switch.This configuration is illustrated in

the setup diagram.

This switch, located in the “Rear Filter Section”,

performs a very useful function when operating the

amplifier in bi-amp mode. By switching this circuit to

the “On” position, all signal common to both left

and right channels is removed from the signal

feeding the rear channels of the 500/5.When the

circuit is “On”, the rear channels will only reproduce

the extreme left and right information in the

recording, creating a realistic ambient effect from the

rear channels without detracting from the imaging

of the front speaker system. Experiment with this

switch to determine if this feature enhances the

sound of your system.

STEREOTRI-AMP MODE:

In this mode, the bandpass feature on the front

channels is activated, configuring the 500/5's

crossover sections to true three-way operation.

This allows the independent powering of tweeters,

midwoofers and subwoofer(s) in the system and

gives extensive control over level matching and

crossover parameters. Left and right tweeter

channels (25W x 2 @ 3 - 4Ω per channel), high-

pass filtered. Left and right midwoofer channels

(100W x 2 @ 1.5 - 4Ω per channel), bandpass

filtered. One mono subwoofer channel (250W x 1

@ 1.5 - 4Ω), low-pass filtered.

Input connection options for the Tri-amp Stereo

mode are as follows:

A) Single pair of inputs connected to the rear

inputs of the 500/5. In this mode, the user has no

adjustability of subwoofer level from the front of the

vehicle. See diagram A below.

B)Two pairs of inputs connected to the rear and

subwoofer inputs of the 500/5 (a source unit or

APPENDIX B:

Input Sensitivity Level Setting

JLAudio amplifiers utilizing the Regulated

The Nine-Step Procedure

(follow this procedure for each set of channels)

1) Disconnect the speaker(s) from the

amplifier’s “Front”,“Rear” and “Subwoofer

Output” connectors.

7) Connect the AC voltmeter to the “Speaker

Outputs” or “Subwoofer Output” connectors of

the channel set that you are adjusting. For the

stereo channels, it is only necessary to measure one

channel. If bridged, make sure you test the voltage at

the correct connectors (L+ and R–).

8) Increase the “Input Sens.” control until the

target voltage is delivered for that set of channels.

If excessive voltage is read on either set of channels

with the control at minimum (full counterclockwise),

switch the appropriate “InputVoltage” switch to

“High” and re-adjust.

Intelligent Power Supply (R.I.P.S.) allow delivery of

their rated power when connected to any load

impedance from 1.5 - 4Ω per channel (3 - 8Ω

bridged) and when connected to a charging system

with any voltage from 11 - 14.5V. This design is

beneficial for many reasons. One of these reasons is

ease of setup. Because each JLAudio amplifier will

always deliver the same amount of power within its

operational range of impedances and supply

voltages, the maximum, unclipped output is very

predictable.This makes setting the gain structure via

the input sensitivity controls very simple. Following

the directions below will allow the user to adjust

the input sensitivity of the amplifier(s) simply and

easily in just a few minutes using equipment which is

commonly available in installation bays.

2)Turn “Off” all processing on the source unit

and amplifier (bass/treble, loudness, EQ, etc.).

3) In all three input sections, switch the “Input

Voltage” to “Low” and turn the “Input Sens.”

control all the way down (counterclockwise).

4) Set the source unit volume to 3/4 of full

volume. If either set of channels is being driven by a

source unit’s dedicated subwoofer output, also

adjust the source unit’s subwoofer level control to

3/4 of maximum output.This will allow for

reasonable gain overlap with moderate clipping at

full volume.

5) Using the chart below, determine the target

voltage for input sensitivity adjustment according to

the nominal impedance of the speaker system

connected to each set of outputs.

6)Verify that you have disconnected the

speakers before proceeding. Play a track with an

appropriate sine wave (within the frequency range

to be amplified by the set of channels being

adjusted) at 3/4 source unit volume.

9) Once you have adjusted each set of

channels to its maximum unclipped output level,

reconnect the speaker(s).The “Input Sens.”

controls can now be adjusted downward if any

channels require attenuation to achieve the

desired system balance.

Necessary Equipment

• Digital ACVoltmeter

IMPORTANT

• CD with a sine-wave test tone recorded at 0 dB

reference level in the frequency range to be

amplified for that set of channels (50 Hz for

subwoofer channels, 1 kHz for a midrange

application). Do not use attenuated test tones

(-10 dB, -20 dB, etc.).

Do not increase any “Input Sens.” setting in

the system beyond the maximum level established

during this procedure. Doing so will result in

audible distortion and possible speaker damage.

It will be necessary to re-adjust the “Input

Sens.” for the affected channels if any equalizer

boost is activated after setting the “Input Sens.”

with this procedure.This applies to any EQ boost

circuit, including the amplifier’s “Bass EQ” and

source unit tone controls or EQ circuits. EQ cuts

will not require re-adjustment.

APPENDIX C:

Master/Slave Configurations

With the flexible on-board crossovers and

processing incorporated into the 500/5, it is

possible to connect additional JL Audio 250/1

amplifiers in a “Master/Slave” configuration, with

each amplifier driving its own speaker system but

controlled by the processing and filtering of the

500/5's subwoofer section.This is very useful if

additional subwoofer power is desired in a system.

To create a Master/Slave configuration,

configure the 500/5's subwoofer section as you

would normally do to drive one subwoofer

system, then do the following to connect

additional slave amplifiers:

2) Connect an RCA cable from the 500/5's

preamp outputs to the main input of the first

“Slave” 250/1 amplifier. Set the “Slave” amplifier’s

“Amp LP Filter” to the “Off” position.This will

defeat the LP filter and the bass processing of this

“Slave Amplifier”.

3)The input sensitivity of the two amplifiers

needs to be adjusted independently. Set the

subwoofer channel of the 500/5 and the slave

250/1 amplifier to the same target voltage using

the procedure outlined in Appendix B (page 22).

Do not increase the “Input Sens.” setting for

any amplifier channel in the system beyond the

maximum level established during the procedure

outlined in Appendix B (page 22). Doing so

will result in audible distortion and possible

speaker damage.

4) If you would like to run a third amplifier in

“Slave” configuration, select the “Full-Range”

position on the “Output Mode” switch of the first

“Slave” amp.Then, connect an RCA cable from

the first “Slave” amplifier’s preamp outputs to the

second “Slave” amplifier. As you did with the first

“Slave” amp, set the second “Slave” amplifier’s

“Amp LP Filter” to the “Off” position.Then,

calibrate the third amplifier’s “Input Range” and

“Input Sens.” controls in the same manner as you

did for the second amplifier.

Additional amplifiers may be added to this

“Master/Slave” configuration following the same

procedure as in step 4.

Once you match the input sensitivities of all

the amplifiers, you can use the “Master” amplifier’s

“Sub LP Filter”, “Infrasonic Filter” and “LF Boost”

features to control the “Slave” amplifier(s).

The diagram below shows a Master/Slave

configuration with one “Master” 500/5 (top

amplifier) and two “Slave” 250/1 amplifiers.

Switches and controls that are defeated in the

“Slave” amplifiers are printed in gray.

NOTE: These settings are intended

as a “baseline” for tuning this system. Depending

on the vehicle, personal taste and the audio

components specific to your system, some

variation in the Subwoofer Channel Control

Section, Filter Sections and Input Sections may be

necessary for optimum performance.

1) In the Preamp Output Section of the 500/5

select the “Sub LP” position on the “Signal From”

switch. This will send a parallel, mono-summed

signal from the 500/5's “Sub LP Filter” section to

its preamp outputs.

The Master amplifier’s bass processing features are

active and affect all three amplifiers equally.

APPENDIX D: TROUBLE SHOOTING

“MY AMPLIFIER DOESN’TTURN ON”

“MY AMPLIFIERTURNS ON, BUTTHERE IS NO OUTPUT”

Check the input signal using an AC voltmeter to measure the

Check to make sure there is +12V at the “Remote” connection of

the amplifier. In some cases, the turn-on lead from the source

unit is insufficient to turn on multiple devices and the use of a

relay is required. To test for this problem, jump the “+12V”

wire to the “Remote” terminal to see if the amplifier turns on.

If this does not work, proceed to the next step.

voltage from the source unit while an appropriate test tone

is played through the source unit (disconnect the RCA

cables from the amplifier prior to this test).The frequency

used should be in the range that is to amplified by the

channels being tested (example: 50 Hz for a sub bass

amplifier channel and 1 kHz for a full range amplifier

channel). A steady voltage should be present at the output

of the RCA cables. If you are receiving a sufficient voltage

(between 0.2 and 8.0-volts), check to ensure that the

speaker wires are making a good connection with the metal

inside the amplifier. The connectors are designed to accept

up to an 8 AWG wire. If you are using significantly smaller

wire (14 AWG or smaller), you may have difficulty making

an adequate connection. In this case, you may find it

necessary to “fold” the wire over once (or twice!) so as to

make a solid connection. Make sure to strip the wire to

allow for a sufficient connection with the input or output

of the amplifier.

Check the fuse, not just visually, but with a continuity meter. It is

possible for a fuse to have poor internal connections that

cannot be found by visual inspection. It is best to take the

fuse out of the holder for testing. If no problem is found

with the fuse, inspect the fuse-holder.

“I GET A DISTORTED / ATTENUATED SOUND COMING OUT OFTHE SPEAKER(S)”

Check the speaker wires for a possible short, either between the

positive and negative or between a speaker lead and the

vehicle’s chassis ground. If a short is present you will

experience distorted and/or attenuated output.The

“Low Ω” light may also illuminate in this situation. It may be

helpful to disconnect the speaker wires from the amplifier

and use a different set of wires connected to a test speaker.

Check the nominal load impedance to verify that the front and

subwoofer channels of the amplifier are driving loads

between 1.5 - 4Ω per channel and that the rear channels

are driving loads between 3 - 4Ω per channel.

Check the input signal and input signal cables to make sure signal is

present at all active inputs and the cables are not pinched or

loose. It may be helpful to try a different set of cables and/or a

different signal source to be sure.

Check the output of the amplifier. Using the procedure explained in

the previous check item (after plugging the RCA cables back

into the amplifier) test for output at the speaker outputs of the

amplifier. Unless you enjoy test tones at high levels, it is a good

idea to remove the speaker wires from the amplifier while

doing this. Turn the volume up approximately half way.

5 volts or more should be measured at the speaker outputs.

This output level can vary greatly between amplifiers but it

should not be in the millivolt range with the source unit at half

volume. If you are reading sufficient voltage, check your speaker

connections as explained above.

“MY AMPLIFIER SHUTS OFF ONCE IN AWHILE, USUALLY AT HIGHERVOLUMES”

Check your voltage source and grounding point.The R.I.P.S. power

supply is rated to operate with source voltages between

“MY AMPLIFIER’S OUTPUT FLUCTUATESWHEN ITAP ON IT OR HIT A BUMP”

Check the connections to the amplifier. Make sure that the insulation

for all wires has been stripped back far enough to allow a

good contact area inside the amplifier terminal.

11 - 14.5V. Shutdown problems at higher levels can occur

when the charging system voltage drops below 10 volts.These

dips can be of very short duration making them extremely

difficult to detect with a common DC voltmeter.To ensure

proper voltage, inspect all wiring and termination points. It is

also a good idea to improve the vehicle’s factory ground wire

and termination point. Grounding problems are the leading

cause of mis-diagnosed amplifier failures.

Check the RCA connectors to ensure that both the center pin and

the outer shield are making good contact with the input jacks

on the amplifier.

“HOW DO I PROPERLY SETTHE INPUT SENSITIVITY ON MY AMPLIFIER”

Please refer to Appendix B (page 22) to set the input sensitivity for

maximum, low-distortion output.
