5. Parentah Operasi
5.1. Mimiti Power-Up
After all connections are made and verified, reconnect the vehicle's negative battery terminal. Turn on your head unit. The amplifier should power on, indicated by an LED indicator (if present).
5.2. Adjusting Gain and Crossover
The amplifier features adjustable gain controls to match the output of your head unit and crossover settings to optimize sound for your speakers.
- Kontrol Gain: Start with the gain control set to minimum. Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back off slightly.
- Crossover (HPF/LPF): Adjust the High-Pass Filter (HPF) for full-range speakers to prevent low frequencies from distorting them. Adjust the Low-Pass Filter (LPF) for subwoofers to only allow low frequencies.
5.3. Bass EQ Control
The Bass EQ control allows you to boost low frequencies. Use this feature sparingly and adjust carefully to avoid speaker damage or excessive distortion. Start with the Bass EQ at its minimum setting and increase gradually to achieve the desired bass response.
