ការដំឡើងនិងការដំឡើង
Careful installation is crucial for optimal performance and safety. Ensure the vehicle's battery is disconnected before beginning.
ទីតាំងដំឡើង៖
Choose a dry, well-ventilated location away from direct sunlight and heat sources. Ensure sufficient space around the amplifier for air circulation to prevent overheating. Secure the amplifier firmly to a solid surface using appropriate hardware.
ការតភ្ជាប់ខ្សែភ្លើង៖
- ថាមពល (B+): Connect a 4 AWG (21mm²) power cable directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Install a 100A fuse within 18 inches (45 cm) of the battery.

នៅពេលដំឡើងរួច សូមអនុវត្តតាមជំហានទាំងនេះដើម្បីកំណត់រចនាសម្ព័ន្ធ និងដំណើរការរបស់អ្នក ampរស់រានមានជីវិត៖
- ការបញ្ចូលថាមពលដំបូង៖ Reconnect the vehicle's battery. Turn on your head unit. The blue LED on the amplifier should illuminate, indicating it is powered on.
- ការកែតម្រូវការទទួលបាន៖ Set the head unit volume to about 75% of its maximum. Slowly increase the amplifier's gain control (Input Sensitivity) until you hear distortion or the red clipping LED illuminates. Then, reduce the gain slightly until the distortion disappears or the red LED turns off. This ensures maximum clean output.
- ការកំណត់តម្រង៖
- HPF (តម្រងឆ្លងខ្ពស់)៖ Use this to block low frequencies from reaching your speakers, typically for full-range or mid-range speakers. Adjust the frequency knob between 20Hz and 90Hz.
- LPF (Low Pass Filter)៖ Use this to allow only low frequencies to pass, typically for subwoofers. Adjust the frequency knob between 90Hz and 20kHz.
- ការធ្វើតេស្តសំឡេង៖ Play various types of music to fine-tune the gain and filter settings for optimal sound quality.
