4. OPERATIONS
Selecting input voltage
XH amplifiers accommodate a wide range of signal input voltages (0.2V to 8V). This wide range is split up into three ranges, which are accessible through
switches located in the “Gain” area of the amplifier.
•0.2V-0.6V selects an input sensitivity range between 200mV and 600mV.
•0.6-2V selects an input sensitivity range between 600mV and 2V.
•2V-8V selects an input sensitivity range between 2V and 8V.
The gain rotary control operates within these voltage windows.
Note:
Most decks, even 4V and 5V units do not operate at full output voltage. This requires the switch to be set in the 0.6-2V range.
Setting the operating level
The gain switches allow you to set the nominal operating level of the amplifier from 0.2 to 8V for RCA inputs or 500mV to 5V for speaker level inputs. This wide adjustment range accommodates virtually any source unit brand.
Once you set the correct range using the IVS, you must adjust the gain to match the amplifiers sensitivity to that of the source unit. The gain control is not a volume control. It exists only to allow an amplifier to be used with different models and brands of head units.
Improving bass sound
The amplifiers feature a narrow-frequency band bass boost circuit (known as “high- Q”). Acting much like an equalizer, the bass boost control lets you tune low-frequen- cy audio response to compensate for a less than ideal subwoofer enclosure design. The added boost produces rich, full bass tones that are normally difficult to reproduce in the car audio environment.
•The XH5210 and XH5410 have a switchable gain that is fixed at 45Hz. If you don’t want to boost the bass frequencies, set this control to “OFF.”
•The XH7110 has a variable-frequency bass boost control from 30Hz to 125Hz. It does not have a bass boost on/off switch, but a level control that goes from 0dB to 15dB.
CAUTION
This control can dramatically increase the power output level and could cause speaker damage if you over use it.
XH5210/XH5410/XH7110
Matching subwoofer output to mid-range speakers
The XH7110 features a polarity control switch for reversing the polarity of the output signal. This can be useful when matching the acoustic output of your subwoofers to the output of your mid-range speakers.
Connecting directly to a head unit
The amps provide connections directly to a head unit without a pre-amp output, such as a factory-installed head unit.
WARNING!
When using the speaker (high-level) inputs, the black wire must be grounded at the radio. Failure to do so will result in noise and/or improper operation.
Care and maintenance
Cleaning the case
Use a soft, dry cloth to gently wipe dust and dirt from the unit.
Do not use benzene, thinner, car cleaner, or other cleaners. These substances may damage the unit or cause the paint to peel.
Servicing the unit
In the event that trouble arises, never open the case or disassemble the unit. The internal parts are not serviceable by the user. Opening any components will void the warranty.
CAUTION
Changes or modifications to this product not approved by the manufacturer will void the warranty and will violate FCC approval.

5. INSTALLATION AND WIRING
Read these instructions and the following precautions carefully.
What is included in the box
In addition to this manual, the box contains:
•Amplifier
•High-level speaker input harness
Mounting precautions
If you lack the necessary skills, do not install the amplifier yourself. See your authorized Clarion Dealer for installation recommendations.
•This unit is exclusively for vehicles with a negative ground, 12V power supply.
•This unit requires additional mobile audio components for proper operation.
•Choose a location in the vehicle that provides adequate ventilation around the amplifier. Although any moving air dissipates heat, cool air should run along the length of the fins rather than across them.
CAUTION
Although Clarion amplifiers include heat sinks and protection circuits, mounting an amplifier in a tight space without any air movement will reduce performance and damage the unit’s internal circuitry over time.
The XH7110 does not have a fan. Install it such that air can flow to the bottom of the amplifier.
•Mount the amplifier on a firm, flat surface away from subwoofer enclosures or to any area that is prone to vibration. Do not install the amplifier on plastic or on any other combustible material.
•For easy system setup, mount the amplifier so that the adjustment controls are accessible after installation.
10 XH5210/XH5410/XH7110
•Always use great care when attaching anything to a vehicle! Check clearances on all sides of the planned installation before drilling any holes or installing any screws.
•Make sure the holes you plan to drill will not cut into the fuel tank, fuel lines, brake lines (under the chassis) or electrical wiring. Don’t guess. Check first.
Wiring precautions
Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion Dealer.
•Do not open the case. There are no user-serviceable parts inside. If you require assistance, consult your Clarion Dealer or an authorized Clarion Service Center.
Power
• Before you start, make sure the source unit’s power switch is off.
WARNING!
To prevent short circuits during installation, disconnect the vehicle’s negative (-) battery lead before making any power connections.
Fuses
•To protect the vehicle from fire or explosion in the event of a collision, add an external fuse to the amp’s positive (+) power lead and connect it as close as possible to the vehicle’s plus (+) battery terminal.
Use a fuse rated to the total current consumption of the amplifier. Fuses mounted near the battery should be ~10 Amps larger than fuses on the amplifier itself.
If you are using more than one amplifier, add the total current consumption for the entire system and use the closest available fuse. For example, if you’re connecting both XH5210 and XH5410, install a 100 Amp fuse at the battery.
•Power wire size can greatly affect the performance of your audio system. The Power wire size table indicates the minimum power wire requirements for proper operation.

Manual Owner’s English
Cables
•Whenever possible, route power wire and signal wire on opposite sides of the vehicle. This prevents the signal cables from picking up electrically radiated noise.
•Protect all wire from damage. Where a power wire passes through the fire wall or near exposed metal edges, protect the wire with a rubber or plastic grommet. Use wire loom where possible for further protection.
•Extra cable can cause signal loss and act as an antenna for noise. Use only high quality RCA cables that are no longer than necessary to make a direct connection with the source unit and amplifiers.
•Make sure each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing.
CAUTION
Improper connections may result in unreliable operation and damage the amplifier or the vehicle.
Grounding the amplifier
•A good chassis ground connection is critical to minimize resistance and avoid noise problems.
Use the shortest wire possible. Clean off any paint, primer or sound
deading prior to making this connection.
To minimize resistance and avoid noise problems, securely connect the ground wire to the car chassis and the source unit ground. Using existing bolts is not recommended.

•The last connection you make should
be the ground wire at the amplifier. As the
power supply capacitors in the amplifier are not charged, a spark may be produced when you make this connection.
Use a test light with an incandescent bulb between the ground terminal and the power wire to charge these capacitors if this is a concern. The ground wire is the most important connection to the amplifier. Make sure it is both electrically and mechanically sound.

XH7110 stackable configuration
In this mode, the master amp’s front-panel controls apply to all amplifiers.
For example, setting the crossover frequency on the master sets it on all slaves. This works for all front-panel controls.
Multiple amplifiers can be daisy-chained together. For example, if you had six XH7110’s in a show car, you could control all of them from one master unit (and one remote).
The following describes the configuration of the amplifiers:
Master |
• Route input from the head into the normal mode inputs. |
|
• Set the master/slave switch to Master. |
|
• Route a single RCA cable from the Slave Out to first slave unit. |
First slave |
• Set the master/slave switch to Slave. |

current amplifier’s Slave In. |
Additional slave(s) • Set the master/slave switch to Slave.
•Route a single RCA cable from the previous amplifier’s Slave Out to the current amplifier’s Slave In.
Each amplifier can independently control separate speaker loads (assuming the phase switch on all amplifiers is set the same).
Or, to power a large single load (phase switch opposite on the amplifier), you can bridge across the amplifiers: + and + to load, - and - to each other. The master amp is “speaker +” for in-phase operation.
Any pair of amplifiers could also be bridged, but be careful to set the phase switches correctly.
Setting the gain
After completing the installation, follow these steps to set the gain control and perform the final system checks.
1.Turn the gain control all the way down (counterclockwise).
2.Select the proper input voltage range using the IVS. See “Selecting Input Voltage” in the “Operations” section of this manual.
3.Turn the vehicle’s ignition switch on.
4.Turn the audio system on with the volume turned all the way down.
5.Set all tone or equalization controls to flat positions and turn loudness off.
6.Play a CD and turn the volume up on the head unit until you hear distortion. This should be most of the way up.

7.Turn the volume back down slightly.
8.Slowly increase the gain control (clockwise). Stop when you hear a slight audio distortion.
When the gain is properly set, you should achieve maximum undistorted output with the volume turned up all the way, not half way.
If an oscilloscope is available, monitor the output of the amplifier with the scope, watching for clipping of the waveform. Set the gain so that only minor clipping occurs.
Adjusting the crossover
The XH5210 and XH5410 amplifiers feature fully-adjustable crossovers.
The XH7110 does not have a way to disable the low-pass 24dB slope crossover.
1.On the XH5210 and XH5410, use the X-Over mode switch to select either LP (low pass) or HP (high pass) or OFF for full range.
2.Using the Frequency (Hz) selection control, select the frequency.
Setting the bass boost
1.Initially set the bass boost control to the OFF position.
2.Listen to a variety of music styles (for example, rock, rap, etc.) and switch the bass boost control on until you notice an increase in low bass response.
Note:
Using the bass boost requires the amplifier to produce a great deal of additional power. Use bass boost sparingly.
CAUTION
If you hear a pop caused by speaker overexertion, lower the bass boost to prevent damage to the speaker.
Final system checks
1.Start the engine and turn on the source unit.
2.After a two-second delay, slowly increase the volume control and listen to the audio.
If you hear any noise, static, distortion or no sound at all, check the connections and refer to Troubleshooting. Depending on your system, the volume may become quite loud even at moderate volume control settings. Until you get an “audio feel” for the system’s power, use care when adjusting the controls.
3.Turn the balance controls to their extreme positions and listen to the results. Audio output should match control settings (audio from the left speaker when balance is left).
4.Increase the volume and verify that the amplifier reproduces the audio at full frequencies without distortion.
If you hear distortion check the connections and verify that the gain control is set correctly. Another cause of distortion could be underpowered or damaged speakers. Refer to Troubleshooting.

•Low or no remote turn-on voltage: check remote connections at the amplifier and source unit.
•Blown amplifier fuse: replace with a new fast-blow fuse (same rating).
•Power wires not connected: check battery and ground wiring at the amplifier and check the battery connections.
•Speaker leads shorted: check speaker continuity to ground; it should not show a common ground.
•Speakers not connected or are blown: check speaker connections at the amplifier and measure at speakers. Measure coil impedance at amplifier with speaker wires disconnected.

Whining noise when engine on
•RCA cables too close to the power wire: Separate RCA and power cables. Ground loops are caused by a mismatch in the ground potential (voltage) between two sources. Current flows through the shield of the RCA cable and is quickly picked up by the amplifier. There are several ways to solve this problem:
•Re-ground the amplifier to a more electrically conductive location.
•Re-ground the head unit to a more electrically conductive location.
•Run a ground wire from the head unit to the amplifier ground.
•Upgrade or replace the ground wire on the battery and alternator.
•Run a ground cable from the negative terminal of the battery to the amplifier.
•Wire the entire audio system using a single connection point to the chassis.
•Induced noise: Relocate components away from electrical noise sources:
•Engine control computers.
•ABS brake control modules.

Equalizer: Component that boosts or cuts sound signal frequencies to improve the quality of the sound.
Gain control: gain is the amount of amplification (voltage, current or power) of an audio signal expressed in dB.
Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle per second. IVS: Input Voltage Selector
Octave: the musical principle of dividing sound frequencies into the eight notes of the musical scale.
Ohm: unit of electric resistance PFS: Precise Frequency Selector
RCA input/output: port through which sound travels in and out of the system; “RCA” refers to the type of connector, which was first manufactured by the Radio Corporation of America.
Slope: how fast the sound gets quieter rated in dBs. The higher the dB number, the faster the frequency drops off.
