Operating Instructions
Once installed, the NOBSOUND Bass Control Knob provides two primary adjustments:
- Frequency Control (Left Knob): This knob adjusts the frequency range of the bass output. Rotating it allows you to select the desired low-frequency cutoff, typically between 40Hz and 150Hz. Adjust this to fine-tune which bass frequencies are emphasized or attenuated.
- Gain Control (Right Knob): This knob adjusts the overall output level (volume) of the subwoofer. You can increase or decrease the gain from -12dB to 0dB. This allows for quick adjustments to the bass volume without needing to access your amplifier or head unit settings.
Rotate the knobs gently to achieve your desired sound. These controls are designed for on-the-fly adjustments to match different music genres or personal preferences while driving.
