that support DVD, the default setting is off.

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

audio output format from a menu.



● Make sure that the polarity of the speaker cables is 

correct, and that no bare wires are in contact with the 

metal part of speaker terminals.

● Make sure that the speaker cables are not shorting.

● Make sure the speakers are configured correctly.

¼



● When the Stereo or Mono listening mode is selected, 

only the front speakers and subwoofer produce sound.

¼



● If you use the Dolby Surround listening mode with a 

mono source, such as an AM radio station or mono 

TV program, the sound is concentrated in the center 

speaker.

¼



● When the T-D, Stereo or Mono listening mode is 

selected, the surround speakers produce no sound.

● Depending on the source and current listening mode, 

not much sound may be produced by the surround 

speakers. Try selecting another listening mode.

¼

● When the Stereo or Mono listening mode is selected, 

the center speaker produces no sound.

¼



● Depending on the source and current listening mode, 

not much sound may be produced by the speakers. Try 

selecting another listening mode.

¼



● When the input signal does not include a subwoofer 

audio element (LFE), the subwoofer may not produce 

sound.

¼



● Check the volume. The volume level is adjustable 

between Min, 1 to 79, Max (80). A level of around 40 is 

normal in a domestic environment.

¼



● Using cable ties to bundle audio cables with power 

cords, speaker cables, etc. may degrade the audio 

performance, so refrain from doing it.

● An audio cable may be picking up interference. Try 

repositioning your cables.

¼



● When a listening mode other than Direct, Pure Audio 

(European, Australian and Asian models), or Mono is 

selected, connecting a headphone automatically selects 

Stereo.

¼



● When DTS program material ends and the DTS 

bitstream stops, the unit remains in DTS listening 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, you may not hear any sound because the 

unit does not switch formats immediately. In such case, 

you should stop your player for about 3 or more seconds 

and then resume playback.

● With some CD and LD players, you will not be able 

to playback DTS material properly even though your 

player is connected to a digital input on the unit. This is 

usually because the DTS bitstream has been processed 

(e.g., output level, sampling rate, or frequency response 

changed) and the unit does not 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 malfunction.

¼



● Since it takes longer to identify the format of an HDMI 

signal than it does for other digital audio signals, audio 

output may not start immediately.

● When listening to Dolby Digital and/or DTS sound, 

digital connection is necessary.

● Check the digital audio output setting on the connected 

component. On some game consoles, such as those 

that support DVD, the default setting is off.

● After pressing RECEIVER on the remote controller, 

repeatedly press DISPLAY to switch the display on the 

main unit. You can see the input format.

If the above does not solve the problem, check the 

following.

¼



● Depending on the connecting status of the speaker, 

some listening modes may not be selected. Check the 

details in "Selectable Listening Modes" section.

¼



● You need to have either back speakers or height 

speakers connected. After connecting each of the 

speakers, make sure the connection settings in 

"Configuration" - "Speaker Channels" are correct.

● Dolby Atmos play is only possible when the input signal 

is Dolby Atmos.

¼



● The Pure Audio listening mode cannot be selected while 

Zone 2 is on.

● Check that the output jack of the connected equipment 

and the input jack of this unit are connected correctly.

● Make sure that none of the connecting cables are bent, 

twisted, or damaged.

● Make sure the switching of input screens is proper at the 

monitor side such as a TV.

If the above does not solve the problem, check the 

following.

¼



● The input selector of this unit needs to be in the 

position that corresponds to the jack where the player is 

connected.

● While the Pure Audio (European, Australian and Asian 

models) listening mode is selected only video signals 

input through HDMI IN can be output.

● Check if "Resolution Error" is displayed on the main 

unit display when video input via HDMI IN jack is not 

displayed. In this case, the TV does not support the 

resolution of the video input from the player. Change the 

setting on the player.

● Reliable operation with an HDMI-to-DVI adapter is not 

guaranteed. In addition, video signals from a PC are not 

supported.

● Try switching off the DeepColor function. To turn off the 

DeepColor function, simultaneously press the STRM 

BOX and  ON/STANDBY buttons on the main unit. 

While holding down STRM BOX, press  ON/STANDBY 

repeatedly until "Deep Color:Off" appears on the display.
