Troubleshooting

—Continued

The subwoofer produces no sound?

• The level of the input signal was too low so the sub-

woofer entered Standby mode. Increase the subwoofer
level slightly on the HT-R530.

• Make sure that the subwoofer’s [POWER] switch is

set to ON (not North American models).

• The subwoofer’s OUTPUT LEVEL control is set at

minimum. Turn it up.

• The subwoofer outputs no sound while only speaker

set B is on. Turn on speaker set A.

• 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 48).

Speaker set B produces no sound?

• Speaker set B outputs only analog input signals. Make

sure that the analog audio cables are connected prop-
erly.

There’s no sound with a certain signal format?

• Check the digital audio output setting on the con-

nected device. On some games consoles, such as those
that can play DVDs, the default setting is off.

• With some DVD-Video discs, you need to select an

audio output format from a menu.

Can’t get 6.1 or 7.1-channel playback?

• When speaker B is turned on, speaker set A is reduced

to 5.1-channel playback.

The volume cannot be set to 79?

• When the levels of all speakers have been calibrated

(pages 39, 47), the maximum volume setting may
change.

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

(page 44).

The DVD analog multichannel input doesn’t
work?

• Check the DVD analog multichannel input connec-

tions (page 25).

• To select the DVD analog multichannel input, press

the [MULTI CH] input selector button.

• 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 players, you won’t be able to playback

DTS material properly even though your player is con-
nected 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.

There’s no picture?

• Make sure that all video connecting plugs are pushed

in all the way (page 22).

• Make sure that each video component is properly con-

nected.

• The AV receiver does not convert between formats. So

if your video component is connected to a component
video input, your TV must be connected to the compo-
nent video output (page 23).

• On your TV, make sure that the video input to which

the AV receiver is connected is selected.

• While the Pure Audio listening mode (not North
