4. Obsluha Ampdoživotní
The Stetsom HL 1200.4 offers several controls to fine-tune your audio experience.
4.1. Level Adjustment (Gain)
The 'LEVEL' controls (gain) allow you to match the input signal from your head unit to the amplifier. Adjust these to prevent distortion and achieve optimal sound clarity. Start with the gain at minimum and slowly increase until desired volume is reached without distortion.
4.2. Crossover Settings (HPF/LPF/Flat)
The crossover switches allow you to direct specific frequency ranges to your speakers or subwoofers:
- HPF (High Pass Filter): Cuts frequencies below a set point, ideal for full-range speakers to prevent them from playing low bass.
- LPF (dolnopropustný filtr): Cuts frequencies above a set point, ideal for subwoofers to ensure they only play bass frequencies.
- BYT: Vypne dělicí prvek a umožní průchod celého frekvenčního rozsahu.
4.3. Zesílení basů
The 'BASS BOOST' control allows you to enhance low frequencies. Use this feature sparingly to avoid distortion and potential damage to your speakers.
