6. Opsætning og installation

Follow these steps for proper installation of your amplivligere.

6.1 Montering af Amplivligere

1. Choose a mounting location that is dry, well-ventilated, and secure. Ensure adequate airflow around the ampvarmebeholder til afkøling.
2. Marker monteringshullerne ved hjælp af amplifier som skabelon.
3. Drill pilot holes if necessary, taking care not to damage any vehicle wiring or components.
4. Sikre den ampløfteren ved hjælp af passende skruer.

6.2 Strømledninger

1. Power Wire (12VDC): Run a power wire (minimum 9 AWG / 6mm²) directly from the positive terminal of the vehicle's battery to the amplifier's 12VDC terminal. Install an in-line fuse holder within 18 inches (45 cm) of the battery, using a 30A fuse.
2. Jordledning (GND): Run a ground wire (minimum 9 AWG / 6mm²) from the amplifier's GND terminal to a clean, unpainted metal point on the vehicle's chassis. Ensure a solid electrical connection. The ground wire should be as short as possible, ideally less than 3 feet (1 meter).
3. Fjernbetjeningsledning (REM): Run a remote turn-on wire from your head unit's remote output (typically a blue/white wire) to the ampforsyningens REM-terminal. Denne ledning signalerer amplifier til at tænde og slukke med hovedenheden.

6.3 Lydindgangsforbindelse

1. Tilslut RCA-kabler fra din hovedenheds for-amp udgange til amplifier's RCA inputs (1-2 and 3-4).

6.4 Højttalerledninger

The BD400.4 can operate in stereo or bridged mono mode.

Billede 3: Detaljeret view of the speaker terminals, indicating standard and bridged wiring configurations.

• Stereo-tilstand: Connect each speaker to its corresponding positive (+) and negative (-) terminal on the amplifier. Ensure correct polarity. The amplifier supports 4 channels at 2 or 4 Ohms.
• Brokoblet tilstand: To bridge channels (e.g., for a subwoofer), connect the speaker's positive (+) lead to the positive (+) terminal of one channel and the speaker's negative (-) lead to the negative (-) terminal of the adjacent channel, as indicated by the 'BRIDGED' labels on the amplifier (refer to Image 3). The amplifier supports 2 channels when bridged at 2-4 Ohms.

7. Betjeningsvejledning

Efter installationen skal du følge disse trin for at konfigurere og betjene din amplivligere.

7.1 Forstærkningsjustering

1. Set the GAIN controls on the amplifier to their minimum (fully counter-clockwise) position.
2. Turn on your head unit and set its volume to about 75% of maximum.
3. Øg langsomt GAIN-kontrollen på amplifier until you hear distortion, then back it off slightly until the sound is clear.
4. Repeat for both GAIN 1-2 and GAIN 3-4 controls if using all four channels.

7.2 Delefiltreindstillinger

Use the CROSS switches (L-F-H) to optimize the frequency response for your speakers.

• HPF (Højpasfilter): Use for full-range speakers, tweeters, or midrange drivers to block low frequencies that can cause distortion or damage. The HPF is adjustable from 20 to 90Hz at 12dB/octave.
• LPF (lavpasfilter): Use for subwoofers to block high frequencies. The LPF is adjustable from 90 to 20kHz at 12dB/octave.
• FULL (Full Range): Use if your speakers require a full frequency signal or if you are using an external crossover.
