Häufig gestellte Fragen - APA 4400 CLARION

Wie schließe ich den Verstärker an die Autobatterie an?

Verbinden Sie das BATTERY-Kabel (8 AWG, gelb isoliert) direkt mit dem Pluspol der Batterie und sichern Sie es mit einer externen Sicherung (gleicher Nennwert wie die Gerätesicherung). Das GROUND-Kabel (gleiche Stärke, schwarz) an einen blanken Metallpunkt der Karosserie anschließen. Das REMOTE-Kabel mit dem Remote-Ausgang der Source-Unit verbinden.

Welche Lautsprecherimpedanz kann ich verwenden?

Die empfohlene Impedanz beträgt 4 Ω im Stereo-Modus. Es können Lautsprecher von 2 Ω bis 8 Ω angeschlossen werden. Beachten Sie die Einstellungen des Kanalmodus-Schalters.

Wie stelle ich den Hochpass-/Tiefpassfilter ein?

Verwenden Sie den Filter CH 1/2 oder CH 3/4 Schalter. Wählen Sie HP (Hochpass) um tiefe Frequenzen zu entfernen, LP (Tiefpass) für hohe Frequenzen oder OFF für den vollen Frequenzbereich. Stellen Sie die Grenzfrequenz (50 Hz bis 200 Hz) mit dem Filter Frequency Control ein.

Was ist die Power Guard-Funktion und wie schalte ich sie ein/aus?

Die Power Guard-Schaltung erkennt Übersteuerung und reduziert die Verstärkung, um Verzerrungen zu vermeiden. Sie wird über den Power Guard-Schalter aktiviert (HIGH DEFINITION) oder deaktiviert (HIGH CURRENT). Im deaktivierten Zustand leuchtet die HIGH CURRENT-Anzeige.

Wie wechsle ich den Kanalmodus?

Stellen Sie den Channel Mode Selector für CH 1/2 und CH 3/4 auf STEREO oder MONO. Schalten Sie vor dem Umschalten die Stromversorgung der Source-Unit aus. Die Modi: 4-Kanal (alle Stereo), 3-Kanal (CH 1/2 Stereo, CH 3/4 brückt auf Subwoofer), 2-Kanal (beide Paare brückt).

Warum schaltet sich der Verstärker nach kurzer Zeit ab?

Mögliche Ursache ist ein Überhitzungsschutz. Stellen Sie sicher, dass der Verstärker ausreichend belüftet ist und die Kühlrippen nicht blockiert sind. Prüfen Sie auch, ob die Lautsprecherimpedanz zu niedrig ist oder ein Kurzschluss vorliegt.

Wie reinige ich den Verstärker richtig?

Reinigen Sie das Gehäuse mit einem trockenen, weichen Tuch. Vermeiden Sie Wasser, Reinigungsmittel oder Scheuermittel. Lassen Sie keine Flüssigkeit in die Lüftungsschlitze gelangen.

Welche Sicherung benötige ich und wie tausche ich sie aus?

Der Verstärker verwendet zwei 30 A Automotive-Flachsicherungen (APA4400G). Verwenden Sie nur Sicherungen mit gleicher Stromstärke. Zum Austausch die Abdeckung öffnen, die alte Sicherung entfernen und die neue einsetzen.

Kann ich einen Subwoofer anschließen?

Ja, im 3-Kanal-Modus können Sie einen Subwoofer an die gebrückten Ausgänge CH 3/4 anschließen. Stellen Sie den Filter auf LP (Tiefpass) und den Kanalmodus auf MONO. Die Ausgangsleistung beträgt dann 260 W an 4 Ω.

Was tun, wenn Rauschen oder Störungen im Audio zu hören sind?

Überprüfen Sie die Masseverbindung (kurz und sauber), verlegen Sie Signalkabel getrennt von Stromkabeln, und stellen Sie den Gain richtig ein. Verwenden Sie hochwertige RCA-Kabel und prüfen Sie die Lichtmaschine/Batterie auf Störungen.

APA4400G 100W × 4 channel power amplifier

APA4200G 50W × 4 channel power amplifier

OPERATION AND INSTALLATION MANUAL

-1. INTRODUCTION

Built-In Strong Power Supply

A stable power is supplied even at the instant change of signals through lowering impedance achieved thoroughly by the adoption of PWM DC-DC converter supported by high performance and low loss power MOS-FET, a group of parts with large capacities, low impedance capacitors and toroidal coils and by the further adoption of thick foil substrate (*bus bar), etc. (*APA4400G)

Design emphasizing sound quality

Adopting a low-noise, high slew rate operational amplifier, power amplification element with good current linearity, and through-relays that pass complicated signal lines, this unit has been designed with much consideration of sound quality. Diversified Functions

The preoutput terminal for external amplifier expansion, high-pass/low-pass filter that varies the cut-off frequency from 50 Hz to 200 Hz, and etc., allows full-scale system grade-up of a multi-amplifier, multi-speaker.

Power Guard Circuit

When the amp is in overdrive, this circuit detects any distortion and automatically holds down the input gain to prevent unpleasant clipping distortion. The power guard circuit can be switched on/off with the selector switch.

High definition: power guard on

High current: power guard off

* The power guard circuit is patented by the McIntosh Laboratories of the U.S.A. Built-in Protection Circuit

This circuit protects against damage to the amplifier from overcurrent and overheat caused by an excessive power voltage and short-circuit when overloading.

A channel mode selector switch provides the following high output (rated):

APA4400G

• 4-channel mode ... 100W × 4
• 3-channel mode ... 70W × 2 + 260W × 1
• 2-channel mode ... 200W × 2

APA4200G

• 4-channel mode ... 50W × 4
- 3-channel mode ... 35W × 2 + 110W × 1
• 2-channel mode ... 100W × 2

Protection Circuit

A protection circuit is used to constantly protect against damage to the amplifier from loads, short-circuits, overcurrents, overheating, etc.

Low-heat Design

Reduced power supply circuit heat loss and a large fan (APA4400G) with a high cooling efficiency structure reduce the heat generated during operation.

6. INSTALLATION

The section lists mounting and wiring precautions for installing the Clarion APA4400G/APA4200G car audio amplifier. Combined with the experience of a professional installer, these safeguards are sufficiently detailed to successfully complete installation. If you do not have the necessary skills, do not install the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations.

Mounting Precautions

Although this Clarion amplifier incorporates a large heat sink and multi level protection circuits, mounting any amplifier in a confined space without any air movement can still damage internal circuits over time. Choose a site that provides adequate ventilation around the amplifier. For easy system set-up, mount the amplifier so the controls and fuse will be accessible after installation.

In addition, observe these precautions:

• For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Remember, any moving air will dissipate heat.
• Mount the amplifier on a rigid surface. Do not install the amplifier on plastic or other combustible material.
• Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, brake lines (under chassis), or electrical wiring.

Cautions on installation

1. Be sure to use the screws supplied with this amplifier to install it in your car. Mounting the amplifier using screws other than those supplied may lead to malfunctioning of the unit.
2. When you mount the amplifier, be careful not to damage the wiring in your car with tools or parts such as tapping screws.

Installation procedure

1. Open six holes (ø3.5 mm) to mount the unit.
2. Use the six tapping screws (5 × 30) to secure the unit. (APA4400G) [For fixing the APA4200G, use the four tapping screw (5 × 30).]
3. When mounting the unit on a plastic plate or carpet, use the plate nuts.

Figure 11 Installation Procedure

Wiring Precautions

• Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion dealer.
• Before installation, make sure the source unit power switch is turned OFF.
• Disconnect the negative (-) lead at the battery before making any power connections.
• When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may damage your equipment.
• A secure, clean ground connection is critical to the performance of your Clarion car audio amplifier. Use the shortest ground wire possible to minimize resistance and avoid noise problems.
• Add an external fuse on the positive (+) power lead and connect it as close as possible to the vehicle's (+) battery terminal. Use a rating that equals the total current consumption at full output of all amplifiers in the system. Adding an external fuse will protect the electrical system from short-circuits that can cause fire.
• Refer to Figure 12 when making electrical connections. Connect the amplifier's positive (+) power lead via a fuse directly to the positive (+) terminal on the car battery. Do not connect this wire to the car's fuse panel. Use the yellow-insulated 8 gauge (for APA4400G) or 10 gauge (for APA4200G) (or longer) wire for the amplifier's positive (+) power lead and the same gauge black insulated wire for the ground.
• A ring terminal cannot be used for the speaker output terminal of the APA4400G and the APA4200G, and for the power source terminal of the APA4200G. (The terminal screw has been designed not to come off.)
• When replacing an amplifier's fuse, always use one having the same current rating. Substituting with a higher-rated fuse can reduce protection and may result in serious damage to the amplifier.
• Never ground the speakers to the vehicle chassis or body.
• Make sure that your vehicle's electrical system (i.e., alternator, battery, etc.) is capable of handling the additional load. If you are planning to install a multi-amplifier system, you may need to add a second battery and possibly upgrade the alternator with a higher-output-rated model. Consult your Clarion dealer for recommendations.
• To avoid possible noise problems, run the amplifier's positive (+) power lead along one side of the vehicle to the battery. Run the remote turn-on wire and RCA audio cable down the center, and route the speaker wires along the remaining side. If wires must cross, run the perpendicular to each other.
• When creating passage holes for the power wire, use grommets to eliminate any sharp edges created during drilling. This will protect the wire from being nicked and causing a short-circuit.
• Extra cable causes signal loss and acts 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 or equalizer.
• Depending on the type of system being installed, refer to the examples in Figures 4 through 9 for information on wiring and setting the operation mode.

7. FINAL SYSTEM CHECKS

1. Start the engine and turn on the source unit. After a short two-second delay, slowly raise the volume and listen to the sound. If you hear any noise, static, distortion, or no sound at all, check the connections, and also refer to the "Troubleshooting" section. Depending on your system design, the levels may become quite loud even a low volume control settings. Until you get a "feel" of the power of the system, use care when adjusting the controls.

2. Adjust the balance control from left to right and listen to the results. Audio imaging should match control settings.

3. TROUBLESHOOTING
