៣.១. ការតភ្ជាប់បញ្ចូលសំឡេង
The IR 800.4 supports both RCA (low-level) and High Input (high-level) connections. Do not use both simultaneously, as this can cause unwanted noise and ampបញ្ហា lifier ។
- ការបញ្ចូល RCA៖ Connect RCA cables from your head unit's pre-out to the RCA input jacks on the amplifier (CH1/CH2 and CH3/CH4).
- ការបញ្ចូលខ្ពស់៖ If your head unit does not have RCA pre-outs, use the high-level inputs. Connect the speaker wires from your head unit directly to the High Input terminals on the ampកាន់តែចាស់។

ភ្ជាប់ឧបករណ៍បំពងសំឡេងរបស់អ្នកទៅ amplifier's speaker output terminals using 13 AWG cables. Ensure correct polarity (+ to + and - to -). The IR 800.4 supports both stereo and bridge modes. Always check the minimum impedance supported by the amplifier for your chosen configuration.
- របៀបស្តេរ៉េអូ: Connect one speaker per channel. Minimum impedance is 2 Ohms per channel.
- របៀបស្ពាន៖ Combine two channels to power a single speaker or subwoofer for increased power. Minimum impedance is 4 Ohms in bridge mode.

នៅពេលដំឡើងរួច សូមកែតម្រូវ amplifier settings for optimal audio performance:
- ការគ្រប់គ្រងកម្រិត៖ Adjust the "LEVEL" knob for each channel pair (CH1/CH2 and CH3/CH4) to match the output voltage of your head unit. Start with the level at minimum and slowly increase it until the sound is clear and distortion-free at your desired maximum volume.
- Crossover Settings (HPF/LPF):
- HPF (តម្រងឆ្លងខ្ពស់)៖ Fixed at 90 Hz. When active, it allows frequencies above 90 Hz to pass through, typically used for full-range speakers to prevent low bass distortion.
- LPF (Low Pass Filter)៖ Fixed at 90 Hz. When active, it allows frequencies below 90 Hz to pass through, typically used for subwoofers.
- FLAT Mode: When selected, both HPF and LPF are deactivated, allowing the amplifier to reproduce all frequencies supported by the amplifier without filtering.
- បាសជំរុញ: Use this control to enhance low-frequency output. Adjust carefully to avoid distortion.
