PLANNING YOUR INSTALLATION

It is important that you take the time to read this manual and that you plan out your installation carefully. The following are some considerations that you must take into account when planning your installation.

Cooling Efficiency Considerations:

The outer shell of your JL Audio amplifier is designed to remove heat from the amplifier circuitry. For optimum cooling performance, this outer shell should be exposed to as large a volume of air as possible. Enclosing the amplifier in a small, poorly ventilated chamber can lead to excessive heat build-upand degraded performance. If an installation calls for an enclosure around the amplifier, we recommend that this enclosure be ventilated with the aid

of a fan. In normal applications, fan-coolingis not necessary.

Mounting the amplifier upside down is strongly discouraged. If mounting the amplifier under a seat, make sure there is at least 1 inch (2.5 cm) of space above the amplifier’s outer shell to permit proper cooling.

Safety Considerations:

Your amplifier needs to be installed in a dry, well-ventilatedenvironment and in a manner which does not interfere with your vehicle’s safety equipment (air bags, seat belt systems, ABS brake systems, etc.). You should also take the time to securely mount the amplifier so that it does not come loose in the event of a collision or a sudden jolt to the vehicle.

Stupid Mistakes to Avoid

Check before drilling any holes in your vehicle to make sure that you will not be drilling through a gas tank, brake line, wiring harness or other vital vehicle system.

Do not run system wiring outside or underneath the vehicle. This is an extremely dangerous practice which can result in severe damage to your vehicle and person.

Protect all system wires from sharp metal edges and wear by carefully routing them, tying them down and using grommets and loom where appropriate.

Do not mount the amplifier in the engine compartment, under the vehicle, on the roof or in any other area that will expose the amplifier circuitry to the elements.

PRODUCT DESCRIPTION

The JL Audio XD200/2 is a two-channel,full-rangeaudio amplifier utilizing JL Audio NexD™ultra-highspeed switching technology to deliver outstanding fidelity and efficiency.

The XD200/2 can be operated with a wide variety of source units and system configurations.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence for a typical amplifier installation, using an aftermarket source unit or OEM Interface processor (like the CleanSweep CL441dsp).

Additional steps and different procedures may be required in some applications. If you have any questions, please contact your authorized JL Audio dealer for assistance.

1) Disconnect the negative battery post connection and secure the disconnected cable to prevent accidentalre-connectionduring installation.This step is not optional.

2) Run 8 AWG (minimum) power wire from the battery location to the amplifier mounting location. Take care to route the wire in such a way that it will not be damaged and will not interfere with vehicle operation. Use 4 AWG or larger power wire and a power distribution block if additional amplifiers are being installed with the XD200/2.

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 securely connected to the amplifier.

4) Run signal cables and remoteturn-onwire from the source unit to the final amplifier mounting location.

5) Run speaker cables from the speaker systems to the amplifier mounting location.

6) Find a good, solid metal grounding point close to the amplifier and connect the negative power wire to it using appropriate hardware (use of the JL Audio ECS master ground lug,XB-MGLUis recommended). Use 8 AWG 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.

8) Connect the positive and negative power wires to the amplifier. A fuse near

the amplifier is not necessary if the XD200/2 is the only device being run from the fused main power wire. If the fused main power wire is shared by the XD200/2 and other amplifiers or devices, fuse each amplifier/device

within 12 inches (30 cm) of wire length, via a fused distribution block or multiple individual fuse blocks/on-boardfuses.

9) Connect the remoteturn-onwire

to the amplifier.

10)Connect the input cables to the amplifier.

11)Connect the speaker cables to the amplifier.

12)Carefully review the amplifier’s control settings to make sure that they are set according to the needs of the system.

13)Install the power wire fuse (20A for a single XD200/2) and reconnect the negative battery post terminal. Install the fuse (20A) near the amplifier (if applicable).

14)Turn on the source unit at a low level to double-checkthat 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 to obtain the right overall output and the desired balance in the system. See Appendix A (page 14) for the recommended input sensitivity setting method.

16)Enjoy the fruits of your labor with your favorite music.

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.

The XD200/2’s “+12 VDC” and “Ground” connections are designed to accept8-4AWG power wire.8 AWG is the minimum required wire size for this amplifier.

If you are installing the XD200/2 with other amplifiers and wish to use a single main power wire, use 4 AWG, 2 AWG or 1/0 AWG main power wire (depending on the overall current demands of all the amplifiers in the system). This large power wire should terminate into a fused distribution block mounted as close to the amplifiers as possible (within 12 inches / 30cm of wire length). The fused output of the distribution block will connect to the XD200/2 with 8 or 4 AWG power wire. JL Audio ECS fused distribution blocks are recommended (XD-FDBU-2andXD-FDBU-4)

Note: Smaller AWG numbers mean bigger wire andvice-versa(1/0 AWG is the largest, 2 AWG is smaller, then 4 AWG, then 8 AWG, etc.).

To connect the power wires to the amplifier, first back out the set screw on the top of the terminal block, 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 terminal block, 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 8 or 4 AWG wire 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-metalconnection between the chassis and the termination of the ground wire. For optimal grounding, we recommend the use of a JL Audio ECS master ground lug(XB-MGLU).Alternatively, a sheet metal screw or bolt can be used with a star washer.

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.

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.

FUSE REQUIREMENTS

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 XD200/2 is being run from that power wire, we recommend a 20A fuse be used.

If fusing the amplifier near its power connections (when more than one amp is being run from the main power wire), use a 20A fuse. MAXI™ plastic-bodyfuses are recommended.

5

TURN-ONLEAD

The XD200/2 uses a conventional +12V remote turn-onlead, typically controlled by the source unit's remoteturn-onoutput. 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 remoteturn-onoutput, the amplifier’sturn-onlead can be connected to +12V via a switch that derives power from anignition-switchedcircuit.

The XD200/2’s “Remoteturn-onconnector is designed to accept 18 AWG – 12 AWG wire. To connect the remoteturn-onwire to the amplifier, first back out the set screw on the top of the terminal block, using the supplied 2.5mm hex wrench. Strip 1/2 inch (12mm) of wire and insert the bare wire into the terminal block, seating it firmly so that no bare wire is exposed. 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 (not the insulation) is firmly gripped by the set screw.

INPUT SECTION

The XD200/2’s input section allows you to send signals to the amplifier section through the use of two differential-balancedinputs.

Input connections are via up to one pair of traditional RCA-typejacks.

Input Voltage Range:

The XD200/2’s input sections are designed to accept signal voltages from 100mV – 4V. This will accommodate all preamp level signals and many speaker level signals.

To use speaker-levelsources, simply splice the speaker output wires of the source unit onto a pair of RCA plugs. (or use JL Audio part

XD-CLRAIC2-SW)No “line output converter” is needed in most cases.

If you find that the output cannot be reduced sufficiently with a direct speaker level signal applied to the amplifier, you may use a “line output converter” to reduce the signal level.

6 | JL Audio - XD200/2 Owner’s Manual

INPUT SENSITIVITY CONTROL

The control labeled “Input Sens.” can be used to match the source unit’s output voltage to the input stage of the amplifier for maximum clean output. Rotating the control clockwise will result in higher sensitivity (louder for a given input voltage). Rotating the controlcounter-clockwisewill result in lower sensitivity (quieter for a given input voltage.)

To properly set the amplifier for maximum clean output, please refer to Appendix A (page 12) in this manual. After using this procedure, you can then adjust the “Input Sens.” level downward if this is required

to achieve the desired system balance.

Do not increase any “Input Sens.” setting for any channel(s) of any amplifier in the system beyond the maximum level established during the procedure outlined in Appendix A (page 12). Doing so will result in audible distortion and possible speaker damage.

7

FILTER CONTROLS

Most speakers are not designed to reproduce the full range of frequencies audible by the human ear. For this reason, most speaker systems are comprised of multiple speakers, each dedicated to reproducing a specific frequency range. Filters are used to select which frequency range is sent to each section of a speaker system. The division of frequency ranges to different speakers can be done with passive filters (coils and/or capacitors between the amplifier outputs and the speakers), which are acceptable and commonly used

for filtering between mid-rangespeakers and tweeters. Filtering between subwoofer systems and satellite speaker systems is best done with active filters, which cut off frequency content at the input to the amplifier. Active filters are more stable than passive filters and do not introduce extraneous resistance, which can degrade subwoofer performance.

The active filter built into the XD200/2 can be used to eliminate potentially harmful and/ or undesired frequencies from making their way through the amplifier sections to the speaker(s).

This serves to improve tonal balance and to avoid distortion and possible speaker failure. Correct use of this filter can substantially increase the longevity and fidelity of your audio system.

1)“Filter Mode” Control: The XD200/2 employs a 12dB per octave filter which can be configured as ahigh-passorlow-passfilter type, or defeated completely by way of thethree-position“Filter Mode” switch:

“Off”: Defeats the filter completely, allowing the full range of frequencies present at the inputs to feed the amplifier. This is useful for systems utilizing outboard active crossovers or requiringfull-rangereproduction from one or more of the XD200/2’s channel pairs.

“LP” (Low-Pass): Configures the filter to attenuate frequencies above the selected filter frequency at a rate of 12dB per octave. This is useful for connection of subwoofer(s) to the XD200/2 in abi-amplifiedsystem.

“HP” (High-Pass): Configures the filter to attenuate frequencies below the selected filter frequency at a rate of 12dB per octave. This is useful for connection of component speakers to the XD200/2 in abi-amplifiedsystem.

2)“Filter Freq. (Hz)” The filter frequency markings surrounding this rotary control are for reference purposes and are generally accurate to within 1/3 octave or better. If you would like to select the filter cutoff frequency with a higher level of precision, consult the chart in Appendix B (page 13).

Tuning Hint:  If you are using the XD200/2 to drive a subwoofer system (“LP mode), a

component satellite speaker system (“HP mode) or both, 80 Hz is a good baseline “Filter Freq. (Hz)” setting. After properly adjusting the “Input Sens.”, as outlined in Appendix A (page 12), you can fine tune the “Filter Freq. (Hz)” control to achieve the desired system frequency response.

REMOTE LEVEL CONTROL (OPTIONAL)

With the addition of the optional Remote Level Control (HD-RLC),you can control the volume of the XD200/2 from the front of the vehicle. This is useful for subwoofer level control, rear channel level control,center-channellevel control or even as a master volume control for the system.

The HD-RLCconnects to the jack labeled “Remote Level Control” on the Connection Panel of the amplifier using a standard telephone cable (supplied with theHD-RLC).If desired, multiple XD (and HD) amplifiers can be controlled from a singleHD-RLCcontroller using a simple phone line “splitter” and multiple phone cables.

When connected to the amplifier, the HD-RLCoperates as follows. At full counterclockwise rotation, the audio will mute completely. At full clockwise rotation the level will be the same as if theHD-RLCwas not connected at all. In other words, it operates strictly as a levelattenuator.

PREOUTS

The XD200/2 incorporates a pass-throughpreamp output section, so that additional amplifiers can be easily added to the system.

The preamp output delivers the same signal that is connected to the Amplifier Inputs. This can be useful for feeding a subwoofer amplifier when the XD200/2 is being used to drive front speaker systems.

Note: The preamp output signal is not affected by any crossover filter selected (if the input signal isfull-range,the preamp output will befull-range).

9

SPEAKER OUTPUTS

The XD200/2’s speaker outputs are designed to accept 16 AWG - 8 AWG wire. To connect the speaker wires to the amplifier, first back out the set screws on the top of the terminal block, 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 terminal block, 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 XD200/2 is designed to deliver power into speaker loads equal to or greater than 2 ohms when using a “stereo” configuration and speaker loads equal to or greater than 4 ohms when using a “bridged” configuration.

Speaker loads below 2 ohms nominal per channel (or 4 ohms bridged) are not recommended and may cause the amplifier to initiate a protection mode which reduces power output.

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 XD200/2 has been designed for bridging of its channel pair without the need for input inversion adaptors.

To bridge the XD200/2, use the “Left +” and “Right speaker connectors only (the

Left and “Right +” remain unused). When bridged, the amplifier will deliver optimum power into a 4 ohm load.

When the XD200/2 is bridged, it

will deliver 200W x 1 into a 4 ohm load or 150W x 1 into an 8 ohm load. Operating a bridged XD200/2 into a load lower than 4 ohms is not recommended. Because a bridged pair of channels requires that both channels receive input, you need to connect both left and right inputs to the source unit. Connection of only one input will result in reduced power output, increased distortion and can cause

the amplifier to overheat. Do not do this!

When the XD200/2 is operating in bridged mode, the output will be in mono (only one channel). This mono channel can contain right channel only information, left channel only information or the sum of the information from both the right and left channels. In order to achieve one of these options, configure the inputs to that pair of channels in one of these two ways:

1)Left Channel Only or Right Channel Only Information: If you wish to send a left-only or right-only signal to the XD200/2, use a “Y-Adaptor” to split the single channel signal into both left and right RCA inputs. This option is useful when using one XD200/2

to drive left channel speakers only and the another XD200/2 to drive right channel speakers only.

2)Left + Right Channel Information:

When bridged and fed by a stereo input, the XD200/2’s channels will automatically combine the left a nd right channels into a summed mono (left + right) channel. This option is useful when using a bridged XD200/2 to drive a subwoofer system

or a summed mono center channel.

STATUS LED / PROTECTION CIRCUITRY

There is a single multi-colorLED on the top surface of the amplifier to indicate the amplifier’s operating status.

1)Flashing Green: amplifier is powering up, audio output is muted.

2)Constant Green: amplifier is on and functioning normally, audio output is active.

3)Constant Red: Indicates that the amplifier has exceeded its safe operating temperature, putting the amplifier into aself-protectionmode, which reduces the peak power output of the amplifier. When its temperature returns to a safe level, the red

light will return to green and the amplifier will return to full-poweroperating mode.

4)Constant Amber (yellow): Indicates

that an over-currentcondition has occurred and is accompanied by a muting of the affected channel(s). Because the muting behavior may be very short in duration, it may manifest itself as an audible, repetitive ticking noise in the output.Over-currentconditions can be caused by a

speaker impedance lower than the optimum load impedance range for the amplifier or a shortcircuit in the speaker wiring. The latter can result from a short circuit between the positive and negative speaker wires or between either speaker wire and the vehicle chassis. The “Status LED” will remain amber for a few seconds, even if theover-currentcondition is of a very short duration. This functionality can be used to diagnose ashort-circuitby only connecting one channel at a time. The“Status LED” will turn amber when you connect the channel that is experiencing

the problem and turn the volume up.

5) LED off / Amplifier Shuts Off Unexpectedly

The only condition that will shut down

an undamaged XD200/2 completely is if battery voltage or remote turn-onvoltage drops below 10 volts. The“Status LED” will turn off when this occurs. The amplifier will turn back on when voltage climbs back above 11 volts. If this is happening in your system, have your charging system and power wiring inspected.

For more information on troubleshooting this amplifier, refer to Appendix D (pages 14, 15).

SERVICING YOUR 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.

If you have any questions about the installation or setup of the amplifier not covered in this manual, please contact your dealer or technical support.

APPENDIX A:

Input Sensitivity Level Setting

Following the directions below will allow the installer to adjust the input sensitivity of the XD200/2 simply and easily in just a few minutes using equipment which is commonly available in installation bays.

Necessary Equipment

Digital AC Voltmeter

CD with a sine-wavetest 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 (-10dB,-20dB, etc.).

The Nine-StepProcedure

1)Disconnect the speaker(s) from the amplifier’s speaker output connectors.

2)Turn off all processing (bass/treble, loudness, EQ, etc.) on the source unit, processors (if used) and amplifier. Set fader control to center position and subwoofer level control to 3/4 of maximum (if used to feed the XD200/2).

3)Turn the “Input Sens.” control all the way down.

4)Set the source unit volume to 3/4 of full volume. This will allow for reasonable gain overlap with moderate clipping at full volume.

5)Using the chart on this page, determine the target voltage for input sensitivity adjustment according to the nominal impedance of the speaker system connected to the amplifier 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 XD200/2) at 3/4 source unit volume.

7)Connect the AC voltmeter to the speaker output connectors of the amplifier. If the channel

pair is operating in stereo, 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 observed with the voltmeter.

9)Once you have adjusted the XD200/2 to its maximum low-distortionoutput level,

reconnect the speaker(s). The “Input Sens.” controls can now be adjusted downward if the amplifier requires attenuation to achieve the desired system balance.

Do not increase any “Input Sens.” setting for any amplifier channel or channel pair 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-adjustthe“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 source unit tone controls or EQ circuits. EQ cuts will not requirere-adjustment.

APPENDIX D: TROUBLESHOOTING

“How do I properly set the input sensitivity on my amplifier?”

Please refer to Appendix A (page 12) to set the input sensitivity for maximum,low-distortionoutput.

“My amplifier doesn’t turn on.”

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 thefuse-holder.

Check the integrity of the connections made to each of the “+12VDC”, “Ground”, and “Remote” terminals. Ensure that no wire insulation is pinched by the terminal set screw and that each connection is tight.

Check to make sure there is +12V at the“Remote” connection of the amplifier. In some cases, theturn-onlead 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 “+12VDC” wire to the “Remote” terminal to see if the amplifier turns on.

“I get a repetitive ticking or popping sound coming out of the speaker(s).”

Check the speaker wires for a possible short, either between the positive and negative leads or between either speaker lead and the vehicle’s chassis ground. If a short is present, you will experience distorted and/or attenuated output. The “Status LED” will turn Amber (yellow) 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 each channel of the amplifier is driving a load equal to or greater than 2 ohms in stereo mode (4 ohms bridged).

“My amplifier’s output fluctuates when I tap 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 terminal block.

Check the input connectors to ensure that they all are making good contact with the input jacks on the amplifier.

14 | JL Audio - XD200/2 Owner’s Manual

“My amplifier shuts off once in a while, usually at higher volumes.”

Check your voltage source and grounding point. The power supply of the XD200/2 will operate with charging system voltages down to 10V. Shutdown problems at higher volume levels can occur when the charging system voltage (or remote turnon voltage) momentarily drops below 10V. 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 may also be necessary to upgrade the ground wire connecting the

battery to the vehicle’s chassis and the power wire connecting the alternator to the battery. Many vehicles employ small (10 AWG - 6 AWG) wire to ground the battery to the vehicle’s chassis and to connect the alternator 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. Grounding problems are the leading cause of misdiagnosed amplifier “failures.”

“My amplifier turns on, but there is no output.”

Check the input signal using an AC voltmeter to measure the voltage from the source unit while an appropriate test tone is played through the source unit (disconnect the input cables from the amplifier prior to this test). The frequency used should be in the range that is to be amplified by the amplifier (example: 50 Hz for a sub bass application or 1 kHz for a full range /high-passapplication). A steady, sufficient voltage (between 0.1 and4.0-volts)should be present at the output of the signal cables.

Check the output of the amplifier. Using the procedure explained in the previous check item (after plugging the input cables back into the amplifier) test for output at the speaker outputs of the amplifier. Remove the speaker wires from the amplifier while doing this to prevent unpleasant noise and possible speaker damage. Turn the volume up approximately half way. 5V AC 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 below.

Check to ensure that the speaker wires are making a good connection with the metal inside the terminal block. The speaker wire connectors are designed to accept up to 8 AWG wire. Make sure to strip the wire to allow for a sufficient connection with the metal inside the terminal block.
