The surround back speak-
ers produce no sound?
The level of the surround back speaker is set
at minimum. Check the volume of the surround back
speaker (page 47).
The Surround Back setting is set to None in
the Speaker Configuration. Check the Surround Back setting in the
Speaker Configuration (page 48).
The selected listening mode doesn’t use the
surround back speakers. Select another listening mode. See page 39
for information on listening modes.
Surround speaker output depends on the
source material, and some material may not
use the surround speakers much. If you’re playing a Dolby Digital EX or
DTS-ES source, make sure that the Dolby
Digital/DTS setting is set to On (page 42).
A low-frequency noise or
hum can be heard? The audio connecting cables at the rear of
the HT-R520 are too close to the power cord. Untangle the audio cables and position them
as far away as possible from the power cord.
The sound is too bright or
harsh and the high range is
not clear?
The treble is set too high. Adjust the treble (page 36).
The subwoofer is not work-
ing or is very quiet?
The Subwoofer setting is set to No in the
Speaker Configuration. Check the Subwoofer setting in the Speaker
Configuration (page 48).
The volume of the subwoofer is set at mini-
mum. Check the volume of the subwoofer
(page 47, 33).
Speaker set A is turned off. The subwoofer
output does not work while only speaker set
B is on.
Turn on speaker set A.
Video
There’s no picture on the
TV?
The TV’s input selector is set incorrectly.
Select the correct input on the TV (i.e., the
input to which the HT-R520 is connected).
The video input and output are different for-
mats.
The HT-R520 doesn’t convert between video
formats. It works as a video signal switcher.
Composite video input signals are output
only by composite video outputs. S-Video
input signals are output only by S-Video out-
puts. And component video input signals are
output only by component video outputs.
Remote contr
oller
The buttons on the HT-R520
work OK but those on the
remote controller don’t?
The wrong remote controller mode is
selected.

Can’t use the remote con-
troller with other AV com-
ponents?
You’ve connected a MiniDisc recorder or
CD recorder to the HT-R520 but haven’t
changed the TAPE/MD/CDR display. Press and hold the [TAPE] input selector
button until MD or CDR, as appropriate,
appears on the display.
The wrong remote control code has been
entered.
If more than one code is listed, try each one
(page 50).
With some AV components, certain buttons
may not work as expected and some may not
work at all.
You’re pointing the remote controller at the
wrong AV component.
To control a component connected via ,
point the remote controller at the HT-R520.
To control a component that’s not connected
via

component.
You’ve made an connection but not an
analog audio connection (RCA).

and an analog audio connection (RCA)
between the component and HT-R520, even
if they are connected digitally (page 30).
