Obrázek 6.2: Detailní view of the control panel, illustrating specific settings for each channel group.
6.1 Přepínač režimů
This switch allows you to select the input mode:
- 2CH: For 2-channel input operation.
- 4CH: For 4-channel input operation.
- 5CH: For 5-channel input operation.
6.2 Level Adjustment (Gain)
Adjust the 'Level' knobs for CH1/2, CH3/4, and SUB to match the output voltage of your source unit. Start with the level at minimum and slowly increase until desired volume is achieved without distortion.
6.3 Crossover (X-OVER)
The amplifier features adjustable crossovers for precise sound tuning:
- HPF (High Pass Filter): Allows frequencies above the set point to pass through. Useful for front/rear speakers to prevent low bass distortion.
- LPF (dolnopropustný filtr): Allows frequencies below the set point to pass through. Primarily used for the subwoofer channel.
- PLNÝ: Bypasses the crossover, allowing full range frequencies to pass.
6.4 Basový ekvalizér
The 'Bass EQ' control for the subwoofer channel allows you to boost bass frequencies (0dB to 12dB) for enhanced low-end response.
6.5 Sub Sonic Filter
The 'Sub Sonic' filter (OFF / 25Hz) helps protect your subwoofer by filtering out extremely low frequencies that are inaudible and can cause damage.
6.6 Remote Turn-On (REM TURN ON / DC SENSE ON)
The amplifier offers two methods for remote turn-on:
- REM TURN ON: Uses a traditional remote turn-on wire from your source unit.
- DC SENSE ON: Automaticky otočí amplifier on when a DC offset is detected on the RCA inputs, typically from a factory head unit.
7. Údržba
Pravidelná údržba zajistí dlouhou životnost a optimální výkon vašeho ampživější.
- Čištění: Pravidelně otírejte ampvnější část záchranáře s měkkým, damp hadříkem. Nepoužívejte agresivní chemikálie ani abrazivní čisticí prostředky.
- Kontroly připojení: Annually inspect all power, ground, and speaker connections for corrosion or looseness. Tighten as necessary.
- Větrání: Zajistěte amplifier's mounting location allows for adequate airflow to prevent overheating, despite its efficient heat rejection design.
- Unused Ports: Keep covers on unused RCA jacks and other ports closed to maintain water resistance.
