GENERAL FUNCTION EXPLANATION
Setting Mixer/Gain Settings in XC-Tune
This adjustment is provided for each channel in order to adjust the amplifi er sensitivity so that it will produce maximum power given a variety of different input signal voltages. Setting this control correctly will ensure that you get maximum performance from your amplifi er and is critical to ensuring that minimal noise and distortion is produced.
Clarion recommends the use of an Oscilloscope or distortion detecting device such as the SMD DD-1 or DD-1+ Distortion Detector to properly set amplifi er sensitivity. A headroom setting of approximately 10dB will help to ensure that music that is recorded at low levels can still be reproduced at high volume levels. With this setting, it is the responsibility of the operator to use the amplifi er in a manner that will not produce audible distortion.
Procedure (Oscilloscope) Method:
1. Obtain a test disc with a selection of Sine Waves recorded at -5dB and -10dB.
2. Turn the gain all the way down on the amplifi er (to the left).
3. Connect the ground terminal of the scope lead to the shield of the RCA cable coming from the source unit. Do no connect the scope lead to the speaker output
terminals.
4. Connect the scope probe to a speaker terminal on the channel you want to adjust.
5. Select a Sine wave frequency that is well away from the chosen crossover frequency. For midrange speakers use 1kHz at -5dB, use 40Hz at -10dB for subwoofers.
6. Turn the source unit up as high as possible without distortion.
7. Monitor the output waveform of the amp on the scope.
8. Increase the sensitivity of the amplifi er until the scope waveform shows a small fl at spot on the top or bottom of the waveform. See Figure 2 for an example of what to look for.
SMD DD-1 Method:
1. Following the instructions provided with the DD-1, use the 0dB track to confi rm the output of the audio signal source is unclipped.
2. Connect the DD-1 to the output of the amplifi er and use an appropriate -5dB or -10dB track. Increase the gain on the amplifi er until the Distortion LED illuminates
You should be able to turn the volume up to almost full (or wherever your source unit clips/ distorts) without hearing distortion. If you can’t turn the volume up most of the way without distortion, the sensitivity control is not adjusted properly.

TRI-ON Auto Sensing Turn-ON Control Switch
All XC7 amplifi ers feature an automatic turn-on circuit called TRI-ON that will activate the amplifi er without the need for a connection to the REM terminal. The switch has three positions - SIG, OFF and DC.
SIG - Signal Detect Mode In this setting, the amplifi er will monitor Channel 1 input for the presence of an audio signal. The signal needs to be moderately loud in order for the amplifi er to activate. NOTE: in some applications,if a speaker is still connected to the wires on this input, the voltage produced from speakers moving when a door is closed may be adequate to trick the amp to turn on. This is the least desirable setting.
OFF - Remote Turn-On Connection Mode In this mode, the amplifi er turns on when a 12V signal is connected to the REM terminal. This is the preferred method of turning on the amplifi er.
DC - DC Voltage Detection Mode In this mode, the amplifi er will monitor Channel 1 input for the DC offset voltage produced by a BTL type amplifi er. To check for the presence of BTL, you can monitor the DC voltage on the speaker wires of the signal source. When you turn on the source, you should see 5-6 Volts DC (or more) on the wires. The presence of this DC voltage will activate the amplifi er.
Remote Turn-On Connection
When +12V is applied to this terminal, the amplifi er will turn on. When installing the amplifi er with an after market source unit, this wire is typically Blue with a White stripe. Some OEM source units have a wire that behaves similarly.
Speaker Connections
The XC7420 amplifi er is capable of driving reactive loads with a minimum nominal impedance of 2 Ohms per channel and 4 Ohms when bridged. When wiring speakers in stereo, the positive and negative leads from the speakers should connected to the respective channels positive and negative connections on the amplifi er. When bridging the amplifi er to drive a mono load, only the outside terminals should be used.
Input RCA Connections
The RCA Input connections should be connected to the RCA Pre-amp outputs of an after market head unit. If you are using a head unit or factory amplifi er that only has speaker level outputs, please use the high-level input adapters that are included with each amp. Please wire them according to the adjacent image. Note, there are components in these connectors used to attenuate the signal. Do not substitute conventional RCA terminals for these adapters or damage will occur. Damage from over-driving the input stage of the amplifi er is not covered under the manufacturer’s warranty.
NOTE: When connecting to the output of a factory amplifi er, you may need to install load resistors on the amplifi er outputs to compensate for the output fi ltering circuit of the amplifi er. A 50 Ohm, 5 Watt resistor usually works well.

USB Connection Port
When connecting your Windows (7, 8 or 10) Laptop or Tablet computer to the amplifi er for tuning, please connect the included 6’ USB cable to this port. It is recommended to power the computer from a battery source to completely eliminate the chance of a ground loop on this connection. If you require more cable length, purchase a longer cable. Do not use an extension. You will need a Type A to Type Mini-B USB cable. Use as short a cable as possible for maximum reliability.
XC-Tune Bootloader Activation Switch
This microswitch is used to put the amp into Bootloader mode. The latest version of the XC-Tune software will automatically put the amplifi er into Bootloader mode to perform software updates. It is unlikely that this switch will need to be used.
BC2 Remote Level Control Installation
Clarion includes a remote level control called the BC2 with the XC7420. The function of the BC2 is programmable in the XC-Tune software. You can adjust the operating range of the control and which channels the control adjust. Please refer to the XC-Tune section of this manual for details.
The BC2 can be easily disassembled for custom installations. Please ensure that the contacts on the circuit board never come in contact with any metal surfaces in the vehicle.
INSTALLATION PLANNING AND CONSIDERATIONS
Clarion XC7 amplifi ers are designed for installation in vehicles with 12V electrical systems and a chassis ground confi guration. While Clarion strongly recommends professional installation of our products to maximize the performance of the product, installing the amplifi er yourself can certainly produce impressive results. Please take into consideration the following when planning your installation.
Take care in choosing a mounting location for the amplifi er. Clarion does not recommend mounting an amplifi er to a subwoofer enclosure. Vibration could damage internal components of the amplifi er.
Ensure that the screws used to mount the amplifi er will not damage anything underneath or behind the mounting location such as interconnects, speaker wires, factory wiring harnesses, computer modules, factory fl uid lines, fuel tanks and more. Mounting hardware should be suffi cient to ensure that the amp will not come loose in the event of a vehicle accident.
All wiring running to and from the amplifi er should be planned so that it’s route does not bring it in proximity of any high-current devices or computer modules. This will help to prevent noise from being induced in the audio system.
• XC7 Amplifi ers incorporate balanced differential inputs. As such, Clarion recommends the use of twisted pair interconnects to ensure that the signal on the center pin and shield of the interconnect allow this circuitry to perform to the best of its ability in terms of rejecting unwanted noise.

INSTALLATION PLANNING AND CONSIDERATIONS CON’T
Although the XC7 amplifi ers are suitable for marine installations, they are in no way water resistant. XC7 amplifi ers should be mounted in a dry, well-ventilated location. The marine features of the amp are designed to handle humid conditions commonly associated with installations in boats.
• Amplifi ers dramatically increase the load on the vehicles electrical system. Please confi rm that the vehicle battery and alternator are in good condition. Clarion recommends the use of a heavy duty AGM style battery to increase current delivery and play time. The use of a high quality, low ESR stiffening capacitor will provide increased instantaneous current to the amplifi er.
Supplying adequate current to your amplifi er may require that some of the factory electrical connections under the hood of your vehicle be upgraded. The industry refers to these upgrades as ‘The Big 3’. Performing these upgrades are optional, but highly recommend. Additional current delivery capability will increase the performance and longevity of any electrical component you add to your vehicle. These upgrades include:
- A new ground wire from the engine in your vehicle to the battery ground terminal.
- A new ground wire from the ground terminal of your battery to the chassis of the vehicle.
- A new power wire from the output of your alternator to the positive terminal of your battery. Some vehicles use aluminum or adhesive-bonded connections between body panels and will not allow adequate current to pass. Clarion recommends that a parallel ground wire be installed to decrease resistance in the return path.
INSTALLATION
1. Once a safe and suitable location has been chosen for your amplifi er, remove both top trim pieces from the amplifi er using a 2mm hex driver. Store the four screws and trim pieces in a safe location.
2. Locate the amplifi er and mark the mounting hole locations.
3. Remove the amp and pre-drill the mounting holes.
4. Replace the amplifi er and secure with adequate hardware.
5. Replace the upper trim panel and secure.
6. Make all the power, signal and speaker connections to the amp.
7. Complete the remainder of the system installation and fi nish tuning the amplifi er and system
8. Install the lower trim panel and secure.

Power Connections
Your XC7-Series amplifi er can only produce power if it is fed power effi ciently. Clarion recommends the use of minimum of 4 AWG copper wire for all power and ground connections. The use of undersized power wiring may result in damage to your amplifi er.
Clarion also recommends performing “The Big Three” upgrade to your electrical system when any high power amplifi er is being installed. This includes upgrading the power wire between your battery and the alternator for both positive and ground connections, as well as the ground connection between the battery and the chassis and/or rear ground location.
The amplifi er ground connection is the most important connection in terms of reliable and effi cient operation of your amplifi er. This connection should be made to a solid and secure point on the vehicle chassis, or directly to the battery. Do not use a seat or seatbelt bolt as a ground location. All of the sound deadening, paint and primer must be removed from the chosen ground location. The ground ring terminal(s) should be secured with a bolt and locking fastener. NOTE: Many new vehicles are assembled with extensive aluminum materials, composites and high strength adhesives. Clarion recommends running a ground wire of the same size as the power wire from the negative terminal of your battery to the ground location of your amplifi er. This is known as a parallel ground.
Wiring Precautions
Read all of the wiring precautions prior to making any connections. If you are unsure and/ or don’t have the necessary installation hardware, contact your local Clarion dealer to perform the installation.
1. Before you begin the installation, make sure the vehicle is not running and is in the OFF position.
2. Disconnect the negative (-) lead of the battery (or batteries) before making any power connections.
3. When making connections, be sure that each connection is clean and secure.
4. Insulate connections with split loom or heat shrink tubing where possible.
5. A fuse holder and fuse must be installed on the lead coming from the positive (+) terminal of the battery. This fuse should located as close a possible to the battery terminal for maximum protection. Clarion does not recommend the use of a circuit breaker as a protection device.
6. The battery fuse rating should equal the total current consumption at full output of the amplifi er(s) connected to that wire. Do not install the fuse until the entire installation has been completed.
