Häufig gestellte Fragen - MX280/4 JL Audio

Wie schließe ich den Verstärker an die Stromversorgung an?

Verbinden Sie das rote Kabel mit der Batterie+ (12V) und das schwarze mit Masse. Verwenden Sie eine Sicherung nahe der Batterie.

Welche Lautsprecherimpedanz ist empfohlen?

Der Verstärker arbeitet optimal mit 2-8 Ohm pro Kanal. Für gebrückten Betrieb mindestens 4 Ohm.

Kann ich den Verstärker überbrücken (brücken)?

Ja, schließen Sie den Lautsprecher an die positiven Klemmen von Kanal 1 und 2 (oder 3 und 4) an. Die Mindestimpedanz beträgt 4 Ohm.

Warum schaltet sich der Verstärker nach kurzer Zeit aus?

Mögliche Ursache: Überhitzung oder Unterspannung. Überprüfen Sie die Belüftung und die Batteriespannung (mind. 12V).

Welche Sicherung wird benötigt?

Verwenden Sie eine 40A-Flachsicherung in der Nähe der Batterie. Ersetzen Sie nur durch gleichen Typ.

Ist der Verstärker für den Außenbereich geeignet?

Ja, das Modell MX280/4 ist spritzwassergeschützt und für den Marine-Einsatz konzipiert.

Wie stelle ich die Eingangsempfindlichkeit (Gain) ein?

Drehen Sie den Gain-Regler langsam hoch, bis Verzerrungen hörbar werden, dann etwas zurückdrehen.

Kann ich einen Subwoofer anschließen?

Ja, überbrücken Sie zwei Kanäle und schließen Sie einen 4-Ohm-Subwoofer an. Der Verstärker liefert dann 200W RMS.

Was bedeutet die Schutz-LED?

Eine rote LED zeigt Kurzschluss, Überhitzung oder Unterspannung an. Beheben Sie die Ursache vor erneuter Inbetriebnahme.

(1) User manual

Product Description

This is a four-channel, full-range audio amplifier utilizing Class D technology for all channels.

Installation Applications

This amplifier is designed for operation with 12 volt, negative-ground electrical systems. Using this product in systems with positive ground and/or voltages other than 12V may result in damage to the product and will void the warranty. This product is not certified or approved for use in aircraft.

Safety Considerations

- Whenever possible, mount the amplifier in a dry, well-ventilated location that does not interfere with other factory installed electronic devices. If a dry environment is not available, a location that is not exposed to heavy splashing may be used.

- While this amplifier is designed to be water-resistant, it should never be submerged under water or subjected to high-pressure water spray. Do not install where it will be directly exposed to the elements.

- Do not mount the amplifier in the engine compartment or in any areas of extreme heat.

- Securely mount the amplifier so that it does not come loose in the event of a collision/sudden jolt or as a result of repeated vibrations during normal operation.

- Check before drilling to make sure that you will not be drilling into an exterior panel/bull, fuel tank, gas/brake line, wiring harness, or other vital system.

- Do not run system wiring outside or underneath the vehicle/vessel. This is an extremely dangerous practice, which can result in severe damage/injury. - Protect all system wires from sharp edges (metal, fiberglass, etc.) by carefully

routing them, tying them down and using grommets and loom where appropriate.

- Secure all wiring as needed, using cable ties or wire clamps to protect them from moving parts and sharp edges.

Installation Procedure/Connections

1. Disconnect the NEGATIVE battery post connection and secure the disconnected cable to prevent accidental reconnection during installation. This is an essential safety precaution during installation!

2. Connect the RED power lead to the positive (+12V) the minimum power wire size for this amplification

3. An appropriate fuse at the main power wire(s) to the amplifier(s) is vital for vehicle/vessel safety. This fuse must be installed within 18 inches (45 cm) of the positive battery post connection. If this is the only device connected to this main wire, use a 35A fuse. Do not install the fuse until the power wire has been securely connected to the amplifier.

4. Connect the BLACK negative ground lead to a clean, solid metal grounding point near the amplifier. This can be to metal chassis ground, if available. If no metal chassis ground is available, it may be necessary to make this connection to the NEGATIVE battery post. 8 AWG is the minimum ground wire size for this amplifier. All ground connections (source unit and amplifiers) should be made at the same location.

5. Connect the BLUE remote turn-on lead to the source unit's positive (+12V) remote turn-on output. If your 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 6. Signal Input (Low-Level): Connect the amplifier's RCA input jacks to the source unit's ramp level output jacks

1. Signal Input (Hi-Level): If your source unit does not offer preamp level signal outputs, you can splice the speaker output wires of the source unit onto a pair of RCA plugs for each input pair or use the JL Audio ECS Speaker Wire to RCA adaptor (XD-CLRAIC2-SW). Make sure to observe correct polarity in making "Hi-Level Input" connections. Failure to do so will result in a loss of signal (poor performance).

2. Connect the speaker output leads to the corresponding speaker wires.

3. Make necessary adjustments to the filter controls and input sensitivity.

WARNING! Failure to make safe, tight, high-integrity power connections can result in fire and extensive damage!

Control Panel Settings and Adjustments

The amplifier's settings and controls are located on the bottom panel beneath a gasketed, protective cover. Remove the four Phillips head screws from the center panel to access the controls and make adjustments. Replace cover when finished and mount the amplifier.

Status LED's / Protection Circuitry

There are two status indicator lights on the wiring end panel of the amplifier. 1. "POWER" (Green): Lights to indicate that the amplifier is turned on and operating normally.

1. "PROTECT" (Red): Lights to indicate the amplifier's protection circuitry has been activated to prevent product failure due to thermal overload, over current or short-circuit to the amplifier's outputs. When this protection mode is activated, the amplifier will shut down to protect its circuitry. When the problem is corrected, the amplifier will return to normal operation and the "Protect" LED will shut off. Connecting the speaker outputs to impedances lower than 2 ohms stereo (4 ohms bridged) will also cause this protection mode to activate.

POWER(Green LED)	PROTECT(Red LED)	Status	Note
ON	OFF	Normal Operation
OFF	ON	Thermal Protection	Lasts until temp cools to normal
OFF/ON	ON/OFF	Over Current	Green/Red LEDs alternate for 1 second
OFF	ON	Short Circuit	Possible audible "popping" noise

Troubleshooting

Problem	Possible Cause	Solution
How to properly set input sensitivity		Please refer to Appendix A to set the input sensitivity for maximum, low-distortion output.
Amplifier doesn’t turn on	Faulty fuse	Remove fuse and check with continuity meter. Replace if necessary.
	Poor connection integrity	Check “+12V”. Ground; and “Remote” leads for pinched wires; ensure tight connections.
	Insufficient “Remote” input	Make sure there is a sufficient +12V supply at the “Remote” connection; if not a relay may be required.
Intermittent output, fluctuates when I tap on it or hit a bump	Poor connection integrity	Make sure insulation has been properly stripped back at connection points for good contact area.
		Make sure input connectors are making good contact with input jacks of the amplifier.
Distorted, attenuated, or popping sound	Faulty speaker connection (Short Circuit / Over Current Protection)	Inspect speaker wires for possible short-circuit, either together or shorted to the vehicle’s chassis ground.
		Check the nominal load impedance at the amplifier is equal to or greater than 2 ohms stereo (4 ohms bridged).
Output shuts off after a while	Overheating condition (Thermal Protection)	Make sure amplifier mounting area has adequate space for ventilation and heat dissipation.
