4.1 Controles e Indicadores

• Volume: Adjusts the overall output level of the subwoofer. Start with this control at minimum and gradually increase to the desired level.
• Interruptor de alimentação: Turns the subwoofer ON or OFF. Always turn on the subwoofer last in your audio chain and turn it off first.
• Elevação do solo: Helps eliminate hum or buzz caused by ground loops. Engage this switch if you experience such noise.
• Fase: Reverses the phase of the subwoofer's output (0° or 180°). Adjust this to achieve optimal acoustic alignment with your full-range speakers, ensuring the bass frequencies are in phase.
• HPF Bypass: Engages or bypasses the internal High-Pass Filter (HPF). When engaged, the HPF typically filters out frequencies below 800 Hz from the output signal sent to linked full-range speakers.
• Indicador de energia: Illuminates when the unit is powered ON.
• Indicador de clipe: Illuminates when the input signal is too high, causing distortion. If this light flashes frequently or stays lit, reduce the input volume from your source or the subwoofer's volume control.
