4. Einrichtung und Installation

4.1 Montage der Ampschwerer

Choose a secure location for mounting the amplifier, such as in the trunk or under a seat. Ensure the location provides adequate ventilation to prevent overheating. Use the provided mounting hardware to secure the ampVerstärker fest auf einer festen Oberfläche befestigen.

4.2 Kabelverbindungen

Before making any connections, ensure the vehicle's negative battery terminal is disconnected.

Stromanschlüsse

• BATT+ (12V Power): Connect a heavy-gauge power cable (e.g., 4 AWG or larger) directly from the positive terminal of the vehicle's battery to the BATT+ terminal on the amplifier. Install an in-line fuse holder (not supplied) within 18 inches (45 cm) of the battery.
• GROUND (GND): Schließen Sie ein dickes Erdungskabel (gleicher Querschnitt wie das Stromkabel) an den GND-Anschluss des Geräts an. ampSchließen Sie den Verstärker an eine saubere, unlackierte Metalloberfläche des Fahrzeugchassis an. Achten Sie auf eine gute elektrische Verbindung.
• REMOTE (REM): Connect a remote turn-on wire (e.g., 18 AWG) from your head unit's remote output to the REM terminal on the ampVerstärker. Dieser Draht schaltet den ampVerstärker mit dem Autoradio ein- und ausschalten.

Lautsprecheranschlüsse

• Connect your subwoofer(s) to the SPEAKER terminals. Ensure correct polarity (+ to + and - to -).
• The AT4000M is 2 Ohm stable. Ensure the total impedance of your connected speakers is not below 2 Ohms.

Eingangsanschlüsse

• Niedrigpegeleingänge (RCA): For best audio quality, connect RCA cables from your head unit's subwoofer or full-range pre-outs to the LEFT and RIGHT RCA INPUTS on the ampschwerer.
• High-Level-Eingänge: If your head unit does not have RCA outputs, connect the speaker wires from your head unit to the HIGH LEVEL INPUTS using the provided connector. The amplifier features remote sensing capability to automatically turn on when a signal is detected.

Remote Bass Knob Connection

• Connect the remote bass knob cable to the 'REMOTE' port on the amplifier's input panel. Mount the bass knob in an accessible location for easy adjustment of subwoofer level.

4.3 Erste Anpassungen

• INPUT LEVEL (Gain): Start with the INPUT LEVEL control set to minimum (MIN). Gradually increase the gain until you achieve a clear, undistorted sound at your desired volume level. Avoid setting the gain too high, as this can cause distortion and damage to speakers.
• FREQ (Low Pass Filter): This control adjusts the low-pass crossover frequency. For subwoofers, set this between 35Hz and 160Hz to filter out higher frequencies, allowing only bass frequencies to pass through. Adjust to blend smoothly with your main speakers.
• BASS-BOOST: This control provides a bass boost from 0 to +18dB at a fixed frequency. Use sparingly to enhance bass response. Excessive bass boost can lead to distortion.

5. Bedienungsanleitung

LED-Anzeigen

• POWER-LED (grün): Leuchtet, wenn die ampDer Verstärker ist eingeschaltet und funktioniert normal.
• PROTECTION LED (Red): Leuchtet, wenn die amplifier enters protection mode due to a fault (e.g., overheating, short circuit, low impedance). If this LED lights up, turn off your audio system and investigate the cause.

Fernsteuerung des Subwoofer-Pegels

The included remote bass knob allows you to conveniently adjust the subwoofer output level from your listening position without needing to access the amplifier direkt.

6. Wartung

• Reinigung: Wischen Sie regelmäßig ab amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or solvents.
• Verbindungen: Regularly check all power, ground, and speaker connections to ensure they are secure and free from corrosion.
• Belüftung: Stellen Sie sicher, dass die amplifier's heat sink fins are not obstructed by debris or other objects to maintain proper cooling.
• Sicherungswechsel: Wenn das amplifier's internal fuses blow, replace them only with fuses of the exact same type and rating. Using incorrect fuses can damage the ampVerstärker oder einen Brand verursachen.
