What to do if my Pioneer S-W90 Subwoofer has no sound but the indicator is lit?
If your Pioneer Subwoofer isn't producing any sound but the indicator light is on, the speaker or accessory RCA plug cord might be incorrectly connected or disconnected. Double-check the connections to ensure they are correctly connected. Also, the LEVEL knob might be set to MIN. Try turning it clockwise slowly to increase the level.
What to do if my Pioneer S-W90 has much noise when listening to AM or FM broadcasts?
If you're experiencing a lot of noise when listening to AM or FM broadcasts with your Pioneer Subwoofer, the AM loop antenna or the FM indoor antenna might be too close to the unit. Try increasing the distance between the AM or FM antenna (for indoor use) and the subwoofer unit.
Why is my Pioneer S-W90 Subwoofer sound distorted?
If your Pioneer Subwoofer is producing distorted sound, it could be due to a level that is set too high. Try turning the LEVEL knob counter-clockwise to decrease it. Also, the input level might be too high. In that case, reduce the amplifier’s output level (volume, bass control, bass boost) by turning it counter-clockwise.
Why does my Pioneer S-W90 Subwoofer make a howling noise?
If you're experiencing a howling noise with your Pioneer Subwoofer, it could be due to a few reasons. First, check if the power supply to the amplifier or speaker switch is turned off; if so, connect the power supply to the amplifier and turn the speaker switch on. Another possible cause is that the subwoofer level is set too high. Try placing the subwoofer a good distance from the speakers and turning the LEVEL knob counter-clockwise to lower the volume.
