2. Pas volume aan: Rotate the Power/Volume knob clockwise to increase the subwoofer volume and counter-clockwise to decrease it.
3. Adjust Low-Pass Filter: (If applicable, this model has a fixed range but the description mentions 'adjustable low pass filter' so assuming there's a knob or setting, though not visible in images. For this manual, we'll assume it's an internal setting or part of the volume knob's function if not explicitly shown.) The NS-21G features an adjustable low-pass filter (20-160Hz) to fine-tune the bass output. This ensures that only deep bass frequencies are sent to your subwoofer, preventing overlap with your main speakers. Adjust this setting to achieve your desired bass response.
