Troubleshooting—Continued

The center speaker produces no sound

•When the Stereo listening mode is selected, the center speaker produces no sound.

•In the Mono listening mode, only the front speakers output sound if the “Output Speaker” setting is set to “Left/Right” (page 98).

•Make sure the speakers are configured correctly (page 90).

The surround back speakers produce no sound

•The surround back speakers are not used with all lis- tening modes. Select another listening mode (page 86).

•Not much sound may be produced by the surround back speakers with some sources.

•Make sure the speakers are configured correctly (page 90).

•While Powered Zone 2 is being used, playback in the main room is reduced to 5.1-channels and the sur- round back speakers produce no sound (page 114).

The subwoofer produces no sound

•When you play source material that contains no infor- mation in the LFE channel, the subwoofer produces no sound.

•Make sure the speakers are configured correctly (page 90).

There’s no sound with a certain signal format

•Check the digital audio output setting on the con- nected device. On some game consoles, such as those that support DVD, the default setting is off.

•With some DVD-Video discs, you need to select an audio output format from a menu.

•Depending on the input signal, some listening modes cannot be selected (pages 80-85).

Can’t get 6.1/7.1 playback

•If no surround back speakers are connected, or the Zone 2 speakers are being used, 6.1/7.1 playback is not possible.

•You can not always select all of the listening modes, depending on the number of the speakers connected (pages 80-85).

The speaker volume cannot be set as required (The volume cannot be set to +18.0 dB)

•Check to see if a maximum volume has been set (page 106).

•After the Automatic Speaker Setup function has been run, or the volume level of each individual speaker has been adjusted (page 94), the maximum volume may be reduced.

•When the “Equalizer Settings” (page 95) is set to “Audyssey”, the maximum possible volume is reduced by 6 dB.

Noise can be heard

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so don’t do it.

•An audio cable may be picking up interference. Try repositioning your cables.

The Late Night function doesn’t work

•Make sure the source material is Dolby Digital, Dolby Digital Plus, and Dolby TrueHD (page 100).

The DVD analog multichannel input doesn’t work

•Check the DVD analog multichannel input connec- tions (page 26).

•To select the DVD analog multichannel input, press the [Multi CH] input selector button.

•Make sure that the “Speakers Type” is not set to “Bi- Amp”. The multichannel DVD input cannot be used if “Speakers Type” is set to “Bi-Amp” (page 45).

•Check the audio output settings on your DVD player.

About DTS signals

•When DTS program material ends and the DTS bit- stream stops, the AV receiver remains in DTS listen- ing mode and the DTS indicator remains on. This is to prevent noise when you use the pause, fast forward, or fast reverse function on your player. If you switch your player from DTS to PCM, because the AV receiver does not switch formats immediately, you may not hear any sound, in which case you should stop your player for about three seconds, and then resume play- back.

•With some CD and LD players, you won’t be able to playback DTS material properly even though your player is connected to a digital input on the AV receiver. This is usually because the DTS bitstream has been processed (e.g., output level, sampling rate, or frequency response changed) and the AV receiver doesn’t recognize it as a genuine DTS signal. In such cases, you may hear noise.

•When playing DTS program material, using the pause, fast forward, or fast reverse function on your player may produce a short audible noise. This is not a mal- function.

The beginning of audio received by an HDMI IN can’t be heard

•Since it takes longer to identify the format of an HDMI signal than it does for other digital audio sig- nals, audio output may not start immediately.

Video

There’s no picture

•Make sure that all video connecting plugs are pushed in all the way (page 21).

•Make sure that each video component is properly con- nected. (pages 24-37)
