5. Nastavení a instalace
Proper installation is crucial for optimal performance and safety. Refer to Figure 4.2 for connection points on the rear panel.
5.1 Místo montáže
The slim design of the RW-108A allows for flexible mounting. Common locations include under a seat, in the trunk, or behind a truck seat. Choose a location that:
- Provides secure attachment to the vehicle chassis.
- Allows for adequate ventilation around the unit.
- Does not interfere with vehicle operation or passenger safety.
- Is accessible for wiring connections and adjustments.
5.2 Zapojení kabeláže
Follow these steps for wiring your subwoofer:
- Napájení (BATERIE +12V): Connect a heavy-gauge power cable (typically 8-gauge or 10-gauge, depending on cable length) directly from the vehicle's positive battery terminal to the +12V terminal on the subwoofer. Install an in-line fuse (not supplied, typically 20A-30A) within 18 inches (45 cm) of the battery.
- Zem (GND): Connect a heavy-gauge ground cable of the same size as the power cable from the GND terminal on the subwoofer to a clean, unpainted metal surface of the vehicle chassis. Ensure a good electrical connection.
- Dálkové zapnutí (REM): Connect a remote turn-on wire from your head unit's remote output (usually a blue/white wire) to the REM terminal on the subwoofer. This wire tells the subwoofer to turn on and off with your head unit.
- Zvukový vstup:
- Nízkoúrovňový vstup (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer or full-range outputs to the "LOW LEVEL" RCA inputs on the subwoofer.
- Vysokoúrovňový vstup (úroveň reproduktoru): If your head unit does not have RCA pre-outs, use the supplied high-level input harness. Connect the speaker wires from your head unit's front or rear speaker outputs to the corresponding wires on the high-level input harness.
- Dálkové ovládání: Plug the wired bass remote control into the "REMOTE CONTROL" port on the subwoofer. Route the cable to a convenient location for the driver.
Důležité: Double-check all connections before reconnecting the vehicle's battery. Incorrect wiring can cause damage to the subwoofer or vehicle electrical system.
6. Návod k obsluze
Once installed, you can adjust the subwoofer's settings to match your audio system and personal preferences. Refer to Figure 4.2 for control locations.
6.1 Počáteční nastavení a seřízení
- Input Level (GAIN): Start with the "INPUT LEVEL" control set to minimum (MIN). Play a familiar piece of music with strong bass. Slowly increase the "INPUT LEVEL" until you hear distortion, then back it off slightly. This matches the subwoofer's input sensitivity to your head unit's output.
- Nízkopropustný filtr (LPF): This control (labeled "LOW PASS") sets the upper frequency limit for the subwoofer. Adjust it to blend smoothly with your main speakers. A common starting point is 80-100 Hz. Frequencies above this setting will not be reproduced by the subwoofer.
- Zesílení basů: The "BASS BOOST" control provides an adjustable boost at a specific low frequency (e.g., 0-12dB at 50Hz). Use this sparingly to enhance bass impact if desired. Excessive boost can lead to distortion and potential damage.
- Fázové řízení: The "PHASE" switch (0°/180°) helps to ensure the subwoofer's output is in phase with your main speakers. Listen to music and switch between 0° and 180°. Choose the setting that provides the most impactful and cohesive bass response.
- Automatické zapnutí: The "AUTO TURN ON" switch (OFF/DC/VOX) determines how the subwoofer turns on.
- OFF: Subwoofer turns on via the REM wire.
- DC: Subwoofer turns on when it detects a DC offset on the high-level inputs (common with factory head units).
- VOX: Subwoofer turns on when it detects an audio signal on the high-level inputs.
6.2 Wired Bass Remote
The wired bass remote (Figure 4.3) allows you to conveniently adjust the subwoofer's output level from the driver's seat without accessing the unit directly. This control only affects the subwoofer's volume and does not override the main "INPUT LEVEL" setting on the subwoofer itself.
7. Údržba
The MB Quart RW-108A is designed for durability and requires minimal maintenance.
- Čištění: K otření vnější strany jednotky použijte měkký, suchý hadřík. Nepoužívejte agresivní chemikálie, rozpouštědla ani abrazivní čisticí prostředky.
- Větrání: Periodically check that the cooling fins and surrounding area are free from dust, debris, or obstructions to ensure proper heat dissipation.
- Spojení: Occasionally inspect wiring connections to ensure they remain secure and free from corrosion.
- Výměna pojistky: If the subwoofer stops working, check the in-line fuse on the power cable and the fuse on the unit itself (refer to Figure 4.2). Replace with a fuse of the exact same type and rating.
