Professional Calibration EQ graphical output
Display
After using the Auto MCACC
Setup, the speaker size setting
is incorrect. • There may have been some low frequency noise in the room from an air-conditioner, motor, etc.
Switch off all other appliances in the room and use Auto MCACC Setup again.
• Depending on a number of factors (room size, speaker placement, etc.) this may occur in some
cases. Change the speaker setting manually in Speaker Setting on page 85, and use the ALL (Keep
SP System) option for the Auto MCACC menu in Automatic MCACC (Expert) on page 72 if this is a
recurring problem.
Can’t adjust the Fine Speaker
Distance setting (page 75)
properly. • Check that the speakers are all in phase (make sure the positive (+) and negative (–) terminals are
matched up properly).
The display shows KEY LOCK ON
when you try to make settings. • With the receiver in standby, press  STANDBY/ON while holding down SPEAKERS to disable the
key lock.
Most recent settings have been
erased. • The power cord was disconnected from the wall while adjusting this setting.
• Settings are only stored if all the zones are turned off. Turn off all the zones before unplugging the
power cord.
The various system settings are
not stored. • Make sure the blue  STANDBY/ON light has gone out before unplugging.
Symptom Remedy
The EQ response displayed in
the graphical output following
calibration does not appear
entirely flat. • There are cases where the graph does not appear flat (even when selecting ALL CH ADJ in the Auto
MCACC Setup) due to adjustments made to compensate for room characteristics to achieve optimal
sound.
• Areas of the graph may appear identical (before and after) when there is little or no adjustment
needed.
• The graph may appear to have shifted vertically when comparing before and after measurements.
EQ adjustments made using
the Manual MCACC setup on
page 74 do not appear to
change the graphical output. • Despite level adjustments being made, the filters used for analysis may not display these
adjustments in the graphical output. However, these adjustments are taken this into account by the
filters dedicated to overall system calibration.
Lower frequency response
curves do not seem to have
been calibrated for SMALL
speakers. • Low frequencies used in bass management (the subwoofer channel) will not change for speakers
that have been specified as SMALL in the configuration, or do not output these frequencies.
• Calibration is performed, but due to your speakers’ low frequency limitations, no measurable
sound is output for display.
Symptom Remedy
The display is dark or off. • Press DIMMER repeatedly to select a different brightness.
After making an adjustment
the display goes off. • Press DIMMER repeatedly to select a different brightness.
You can’t get DIGITAL to
display when using SIGNAL
SEL. • Check the digital connections and make sure that the digital inputs are assigned correctly (see The
Input Setup menu on page 40).
• If the multichannel analog inputs are selected, select a different input function.
2 DIGITAL or DTS does not
light when playing Dolby/DTS
software. • These indicators does not light if playback is paused.
• Check the playback (especially the digital output) settings of the source component.
When playing Dolby Digital or
DTS sources, the receiver’s
format indicators do not light. • Check that the player is connected using a digital connection.
• Make sure that the receiver is set to AUTO or DIGITAL (see Choosing the input signal on page 55).
• Check that the player isn’t set up so that Dolby Digital and DTS sources are converted to PCM.
• Ensure that if there are several audio tracks on the disc, the Dolby Digital or DTS is selected.
When playing certain discs,
none of the receiver’s format
indicators light. • The disc may not contain 5.1/6.1 channel material. Check the disc packaging for more on what
audio tracks are recorded on the disc.
When playing a disc with the
listening mode set to Auto
Surround or ALC,
2 PL II or
Neo:6 appear on the receiver.
• Make sure that the receiver is set to AUTO or DIGITAL (see Choosing the input signal on page 55).
• If a two channel soundtrack is currently playing (including Dolby Surround encoded), then this is
not a malfunction. Check the disc packaging for details about the audio tracks available.
