5. Persediaan dan Pemasangan

Proper installation is crucial for optimal performance and safety. Consider professional installation.

5.1 Lokasi Pemasangan

Choose a dry, well-ventilated location that is protected from direct sunlight and moisture. Ensure sufficient space around the amplifier for air circulation. Avoid mounting on carpet or other materials that could obstruct airflow.

5.2 Sambungan Pendawaian

Refer to the diagrams below for proper wiring. Always disconnect the vehicle's negative battery terminal before making any electrical connections.

5.2.1 Sambungan Kuasa

• +12V (Kuasa): Connect directly to the positive terminal of the vehicle's battery using an appropriate gauge power cable. Install an in-line fuse (not supplied) within 18 inches of the battery.
• GND (Tanah): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid electrical connection.
• REM (Penghidupan Jauh): Connect to the remote output of your head unit. This wire turns the amphidupkan dan matikan lampu isyarat dengan stereo anda.

5.2.2 Signal Input (RCA)

Connect the RCA output from your head unit to the RCA input terminals on the amplebih hidup.

5.2.3 Sambungan Pembesar Suara

Connect your speakers to the speaker output terminals. The MXA214 supports both stereo and bridged mono configurations.

• Mod Stereo: Connect one speaker to the LEFT+ and LEFT- terminals, and another speaker to the RIGHT+ and RIGHT- terminals.
• Mod Mono Jambatan: For a single subwoofer or higher power output, connect the speaker to the LEFT+ and RIGHT- terminals, indicated as BRIDGED. Ensure the speaker impedance is suitable for bridged operation (typically 4 ohms minimum).

6. Arahan Operasi

Once all connections are securely made and verified, reconnect the vehicle's negative battery terminal. The amplifier will power on when your head unit is turned on, indicated by the green POWER LED.

6.1 Penunjuk LED

• KUASA (Hijau): Bercahaya apabila amplifier is receiving power and operating normally.
• PROTECT (Red): Bercahaya apabila amplifier detects a fault (e.g., short circuit, overheating, low voltage) and enters protection mode. The amplifier will shut down to prevent damage.

7. Kawalan dan Pelarasan

The Lanzar MXA214 features several controls to fine-tune your audio system. (Refer to Figure 2 for control locations).

• LEVEL (Gain Control): Melaraskan sensitiviti input bagi amppenguat untuk memadankan vol keluarantage of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
• DASAR ASAS: Provides an adjustable bass enhancement (0 to +18 dB). Use sparingly to avoid distortion.
• CROSSOVER SWITCH (FULL/HPF/LPF): Selects the operating mode for the built-in crossover network.
• PENUH: Full range audio signal is passed to the speakers.
• HPF (Penapis Lulus Tinggi): Allows only frequencies above the set HPF frequency to pass. Useful for full-range speakers to prevent low bass distortion.
• LPF (Penapis Lulus Rendah): Allows only frequencies below the set LPF frequency to pass. Essential for subwoofers.
• HIGH PASS (HPF Frequency Control): Adjusts the cutoff frequency for the High Pass Filter (40 Hz–250 Hz).
• LOW PASS (LPF Frequency Control): Adjusts the cutoff frequency for the Low Pass Filter (40 Hz–250 Hz).
• PHASE CONTROL (0-180°): Adjusts the phase of the output signal. This can help optimize bass response, especially when using a subwoofer with other speakers.
