not stored.

Professional Calibration EQ graphical output

Symptom
The EQ response displayed in
the graphical output following
calibration does not appear
entirely flat.
EQ adjustments made using
the Manual MCACC setup on
page 106 do not appear to
change the graphical output.
Lower frequency response
curves do not seem to have
been calibrated for SMALL
speakers.

Display

Symptom
The display is dark or off.
You can't get DIGITAL to
display when using SIGNAL
SEL.
2 DIGITAL or DTS does not
light when playing Dolby/DTS
software.
When playing Dolby Digital or
DTS sources, the receiver's
format indicators do not light.
When playing certain discs,
none of the receiver's format
indicators light.
When playing a disc with the
listening mode set to Auto
Surround or ALC, 2 PL II or
Neo:6 appear on the receiver.
During playback of DVD-Audio,
the display shows PCM.
Remedy
• Check that the speakers are all in phase (make sure the positive (+) and negative (–) terminals are
matched up properly).
• Perform the Full Auto MCACC procedure before the Precision Distance adjustment (see
Automatically conducting optimum sound tuning (Full Auto MCACC) on page 43).
• Place the microphone accurately in the same position as when the Full Auto MCACC procedure
was performed.
• Do not move the speaker used as the reference point. Also, adjust in order, starting from the front
right speaker.
• When adjusting the speaker positions, do not move the speakers much; only move them about 1
inch towards or away from the microphone.
• If you forget exactly where the microphone should be positioned or if there are problems after the
procedure has been performed repeatedly, re-calibrate the distance using the Full Auto MCACC
procedure, then without moving the microphone redo the Precision Distance adjustment.
• Make sure the blue  STANDBY/ON light has gone out before unplugging.
Remedy
• 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.
• Despite level adjustments being made, the filters used for analysis may not display these
adjustments in the graphical output. However, these adjustments are taken into account by the
filters dedicated to overall system calibration.
• 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.
Remedy
• Press DIMMER repeatedly to select a different brightness.
• Check the digital connections and make sure that the digital inputs are assigned correctly (see The
Input Setup menu on page 45).
• If the multichannel analog inputs are selected, select a different input function.
• These indicators do not light if playback is paused.
• Check the playback (especially the digital output) settings of the source component.
• 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 62).
• 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.
• 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.
• Make sure that the receiver is set to AUTO or DIGITAL (see Choosing the input signal on page 62).
• 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.
• This will occur when playing DVD-Audio material over the HDMI connection. This is not a
malfunction.
