To Next PageTo Next PageWhy does my Onkyo HT-R500 have a rough or scratchy sound?
If you are experiencing rough or scratchy sound and the high range is not clear on your Onkyo Receiver, use the AUDIO ADJUST function to cut the treble response, as the treble control may be too high.
Why is multichannel audio not outputting from my Onkyo HT-R500 Receiver?
If multichannel audio is not outputting from your Onkyo Receiver, set the input signal format to “Multich.” If the input signal format is set to “Auto” or “Analog”. Check that the multichannel output jacks of the component are connected to the DVD FRONT L/R, SURROUND L/R, CENTER and SYBWOOFER jacks.
Why can't I use the LATE NIGHT function on my Onkyo HT-R500 Receiver?
If the LATE NIGHT function cannot be used on your Onkyo Receiver, check that the Ÿ DIGITAL indicator lights up in the display. The playback source is not Dolby Digital encoded.
Why is sound reproduced from the speakers but not recorded on my Onkyo HT-R500?
If sound is reproduced from the speakers but not recorded when using your Onkyo Receiver, make an analog connection. DTS surround sound is unable to be recorded.
Why are no preset channels selected on my Onkyo Receiver?
If no preset channels are selected on your Onkyo Receiver, the preset data in memory is lost. Preset the radio stations again, because the power cord was unplugged for a long time.
