Troubleshooting
En-68
Audio
● Make sure that the speaker setup microphone is not still
connected.
● 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.
● If the MUTING indicator on the display flashes, press
MUTING on the remote controller to unmute the unit.
● While headphones are connected to the PHONES jack,
no sound is output from the speakers.
● If "Audio Select" - "PCM Fixed Mode" is set to "On", set
it to "Off".
If the above does not solve the problem, check the
following.
 There is no sound from the television
● The input selector of this unit needs to be in the position
that corresponds to the jack where the television is
connected.
● If your TV does not support ARC, you need, in addition
to the HDMI OUT jack connection, a digital optical cable
connection between the digital audio out optical jack of
the TV and the DIGITAL IN OPTICAL jack of the unit or
an analog audio cable connection between the audio
output jack of the TV and the AUDIO IN TV jack of the
unit.
 There is no sound from the connected player
● The input selector of this unit needs to be in the
position that corresponds to the jack where the player is
connected.
● 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.
● With some DVD-Video discs, you need to select an
audio output format from a menu.
 One of the speakers produces no sound
● 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.
 Only the front speakers produce sound
● When the Stereo or Mono listening mode is selected,
only the front speakers and subwoofer produce sound.
 Only the center speaker produces sound
● 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.
 The surround speakers produce no sound
● When the T-D (Theater-Dimensional), 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.
 The center speaker produces no sound
● When the Stereo or Mono listening mode is selected,
the center speaker produces no sound.
 No sound from the back speakers and height
speakers
● Depending on the source and current listening mode,
not much sound may be produced by the speakers. Try
selecting another listening mode.
 The subwoofer produces no sound
● When the input signal does not include a subwoofer
audio element (LFE), the subwoofer may not produce
sound.
 Volume is low
● Check the volume. The volume level is adjustable
between Min, 0.5 to 99.5, Max (100). A level of around
60 is normal in a domestic environment.
 There is no sound from a connected turntable
● If your turntable uses an MC cartridge, you must
connect an audio equalizer and either an MC head amp
or an MC transformer.
 Noise can be heard
● 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.
 The sound changes when I connect my headphones
● When a listening mode other than Direct, Pure
Audio or Mono is selected, connecting a headphone
automatically selects Stereo.
 About DTS signals
● 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.
 The beginning of audio received by an HDMI IN
cannot be heard
● 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.
 The volume has suddenly dropped
● If this unit is used for a long time even after the internal
temperature of this unit exceeds a certain threshold,
the volume may be lowered automatically to protect the
circuitry.
 Cannot increase volume when playing AirPlay,
Spotify, or DLNA
● You can set the upper limit for the volume in "WEB
Setup". After pressing the RCV button on the remote
controller, press the SETUP button, select "6. Hardware"
- "Network" - "IP Address" to display the IP address.
After connecting the unit and your PC or smartphone to
the same router, open the browser, enter the IP address
of the unit in the URL field to display the "WEB Setup"
screen. Change the value for "Max Volume" in " WEB
Setup" and click "Save".
