Professional Calibration EQ graphical output
Display
Can’t record video. • Check that the source is not copy-protected.
• The video converter is not available when making recordings. Check that the same type of video cable is
used for connecting both the recorder and the video source (the one you want to record) to this receiver.
Noisy, intermittent, or distorted
picture.
• Sometimes a video deck may output a noisy video signal (during scanning, for example), or the video
quality may just be poor (with some video game units, for example). The picture quality may also depend on
the settings, etc. of your display device. Switch off the video converter and reconnect the source and display
device using the same type of connection (component, S-video or composite), then start playback again.
Symptom
Remedy
Symptom Remedy
The Auto MCACC Setup
continually shows an error.
• The ambient noise level may be too high. Keep the noise level in the room as low as possible (see also
Problems when using the Auto MCACC Setup
on page 9). If the noise level cannot be kept low enough, you
will have to set up the surround sound manually (page 48).
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 48, and use the
ALL (Keep SP SYSTEM)
option for the
Custom Menu
in
Automatic MCACC (Expert)
on page 37 if this is a recurring problem.
Can’t adjust the Fine Speaker
Distance setting (page 42)
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 the
SPEAKERS
button to
disable the key lock.
Most recent settings have been
erased.
• The power cord was disconnected from the wall while adjusting this setting.
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 ADJUST
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 40 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.
Graphical output data seems to
have disappeared.
• If the power is switched off, the measurement data for graphical output to a PC is cleared.
Symptom
Remedy
The display is dark or off. • Press
DIMMER
on the remote control repeatedly to select a different brightness.
After making an adjustment the
display goes off.
• Press
DIMMER
on the remote control repeatedly to select a different brightness.
