56
Possible cause
The amp protection system has been acti-
vated.
The HT-R520 is muted and the MUTING
indicator is on.
The HT-R520 is not connected properly.
The speaker cables are not connected
properly.
The wrong input source is selected.
A pair of headphones are connected.
The input signal format is set to PCM or
DTS.
The volume is set at minimum.
The speakers are configured incorrectly.
The source component is not outputting dig-
ital audio.
A compatible digital audio format is not
selected on the source component.
The Stereo, Direct, or Orchestra listening
mode is selected.
The level of the center speaker is set at
minimum.
The Center setting is set to None in the
Speaker Configuration.
You're listening to a mono sound source
(e.g., TV or AM broadcast) and the PL II/PL
IIx Movie or PL II/PL IIx Music listening
mode is selected, so the sound is concen-
trated in the center speaker.
Selected listening mode doesn't use surround
speakers.
Surround speaker output depends on the
source material, and some material may not
use the surround speakers much.
The level of the surround speaker is set at
minimum.
The Surround setting is set to None in the
Speaker Configuration.
Remedy
Contact your Onkyo dealer.
Unmute the HT-R520 (page 37).
Make sure that all audio connecting plugs are
pushed in all the way. And make sure that the
inputs and outputs of all components are con-
nected properly (page 20).
If your turntable doesn't have a built-in
phono preamp, you must connect one
between your turntable and the HT-R520.
If your turntable uses an MC cartridge, you
must use a compatible phono preamp.
Make sure that the polarity of the speaker
cables is correct and that the bare wires are in
contact with metal part of each speaker ter-
minal (page 17).
Select the correct input source (page 32).
Disconnect the headphones (page 37).
Set the input signal format to Auto (page 45).
Turn up the volume (page 32).
Specify which speakers are connected
(page 48), the speaker distances (page 46)
and adjust the individual speaker levels
(page 47).
Check the digital audio output setting on the
connected device. On some games 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.
The center speaker is not used with these
modes (page 40).
Check the volume of the center speaker
(page 47).
Check the Center setting in the Speaker Con-
figuration (page 48).
Select another listening mode (page 39).
When the Stereo or Direct listening mode is
selected, the surround speakers produce no
sound (page 40).
Check the volume of the surround speaker
(page 47).
Check the Surround setting in the Speaker
Configuration (page 48).
