Troubleshooting—Continued

The surround back speakers produce no sound

•The surround back speakers are not used with all lis- tening modes. Select another listening mode (page 81).

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

•Make sure the speakers are configured correctly (page 95).

•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 130).

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 95).

The Zone 2/3 speakers produce no sound

•The Zone 2/3 speakers only output sources that are connected to an analog input. Check to see if the source component is connected to an analog input.

•Powered Zone 2 cannot be used if “Speaker Type: Front(Speaker A)” is set to “Bi-Amp” or “BTL”, or “Speaker Type: Front(Speaker B)” is set to “Normal”, “Bi-Amp”, or “BTL” (page 61).

There’s no sound with a certain signal format

•Check the digital audio output setting on the source component. On some game consoles, such as those that can play DVDs, the default setting is off.

•With some DVD-Video discs, you need to select an audio format from a menu or with the [AUDIO] button on your DVD player’s remote controller.

•Depending on the input signal, some listening modes cannot be selected (pages 82-86).

Can’t get 6.1- or 7.1-channel playback

•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 130).

Can’t select the Pure Audio listening mode

•The Pure Audio listening mode cannot be selected while Zone 2 is on.

The volume cannot be set as required (The vol- ume cannot be set to +18.0 dB)

•Check to see if a maximum volume has been set (page 115).

•After the Automatic Speaker Setup function has been run, or the volume level of each individual speaker has been adjusted (pages 71 and 100), the maximum vol- ume may be reduced.

Noise can be heard

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on can degrade audio performance, so don’t use them.

•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 109).

The DVD analog multichannel input doesn’t work

•Check the DVD multichannel input connections (page 120).

•Make sure that the multichannel input is assigned to the input selector (page 60).

•Make sure that the multichannel input is selected (page 80).

•Make sure that the “Speaker Type” is not set to “Bi-Amp”. The multichannel DVD input cannot be used if “Speaker Type” is set to “Bi-Amp” (page 61).

•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 listening mode and the DTS indicator remains on. This is to pre- vent 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 playback.

•With some CD 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 recog- nize 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, sound may not be output immediately.

Video

There’s no picture

•Make sure that all video connecting plugs are pushed in all the way (page 33).

•Make sure that each video component is properly con- nected (pages 36-49).

•On your TV, make sure that the video input to which the AV receiver is connected is selected.

•While the Pure Audio listening mode is selected, the video circuitry is turned off and only video signals input through HDMI IN can be output.
