Why is the Denon SYS-76HT subwoofer sound distorted?

  Sound distortion in your Denon Speaker System's active subwoofer can occur if the volume level is too high. Try turning the volume adjustment control counterclockwise to lower the volume. Alternatively, the connected AV surround receiver (or amplifier) may be distorting the sound. In this case, avoid amplifying the bass sound on the AV surround receiver (or amplifier) by lowering the bass adjustment control or volume.

  If the indicator on your Denon Speaker System's active subwoofer is flashing and no sound is being produced, the protective circuit may have been activated due to excess input or a rise in temperature. To resolve this, set the power switch to the “OFF” position, wait at least 1 minute, and then set the power switch back to the “ON” position. If the problem persists, unplug the power supply cord from the AC power outlet and contact your store of purchase.
