- CEA-2006 compliant ampaktar ħaj.
3. Setup u Installazzjoni
Installazzjoni xierqa hija kruċjali għall-prestazzjoni u l-lonġevità tiegħek amplifier. Ensure the vehicle's battery is disconnected before beginning installation.
Immuntar tal- Ampaktar ħaj
Choose a mounting location that is dry, well-ventilated, and secure. Avoid mounting in direct sunlight or near heat sources. Ensure sufficient space around the amplifier għaċ-ċirkolazzjoni tal-arja.

Konnessjonijiet tal-Wiring
All wiring should be of appropriate gauge and securely connected. Loose connections can cause poor performance or damage.
- Power (BATTERY): Connect to the positive (+) terminal of the car battery via an inline fuse (not supplied, typically 50A).
- Ground (GROUND): Connect to a clean, unpainted metal point on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote (REMOTE): Connect to the remote turn-on lead from your head unit. This turns the amplifier mixgħul u mitfi bl-istereo tiegħek.
- Input (RCA jew Livell tal-Ispeaker): Connect your audio source. Use RCA cables for preamp outputs from your head unit, or use the speaker-level inputs if your head unit does not have RCA outputs.
- Riżultat tal-Kelliem: Connect your subwoofer(s) to the speaker terminals. The MRV-M500 is a monoblock amplifier, designed for single-channel output.

4. It-tħaddim tal- Ampaktar ħaj
Power-On Inizjali
Once all connections are made and verified, reconnect the vehicle's negative battery terminal. Turn on your head unit. The blue LED indicator on the amplifier should illuminate, indicating it is powered on.
Aġġustament tal-Kontrolli
- Kontroll GAIN: Dan jaġġusta s-sensittività tad-dħul tal- amplifier to match the output level of your head unit. Start with the gain set to minimum and slowly increase it until the desired volume is achieved without distortion.
- LP FILTER (Low-Pass Filter): This control sets the upper frequency limit for the amplifier's output, ensuring only low frequencies are sent to your subwoofer. Adjust this between 50-400 Hz, typically around 80-120 Hz for most subwoofers.
- BASS EQ (Bass Boost): This control allows you to boost bass output at 50 Hz. Use sparingly to avoid distortion and potential speaker damage. Adjust from 0 to +12 dB.
