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 pos-
sible (see also
Problems when using the Auto MCACC Setup
). If the noise
level cannot be kept low enough, you will have to set up the surround sound manually
(
).
When using only one surround back speaker, connect it to the
SURROUND BACK L
(Single)
terminals.
To use a 5.1-channel speaker set, use the surround speakers for the surround channel,
not the surround back channel.
Make sure there are no obstacles between the speakers and the microphone.
If
Reverse Phase
is displayed, try the following:
— The speaker’s wiring (+ and –) may be inverted. Check the speaker connections.
— Depending on the type of speakers and their installation conditions,
Reverse Phase
may be displayed even if the speakers are properly connected. If this happens, select
GO NEXT
and continue.
— If the speaker is not pointed to the microphone (listening position) or when using
speakers that affect the phase (dipole speakers, reflective speakers, etc.), it may not be
possible to properly identify the polarity.
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 (bass reproduction capabilities of the speakers, room
size, speaker placement, etc.) this may occur in some cases. Change the speaker setting
manually in
, and use the
ALL (Keep SP System)
option for
the
Auto MCACC
menu in
on
problem.
Can’t adjust the Fine Speaker Dis-
tance setting properly.
Check that the speakers are all in phase (make sure the positive (+) and negative (–)
terminals are matched up properly).
SC-LX88 only
: Gauge (value) does not
increase with the
Precision Distance
adjustment.
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)
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 cm towards or away from the microphone.
If you forget exactly where the microphone should be positioned or if there are prob-
lems 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.
The display shows
KEY LOCK ON
when you try to make settings.
With the receiver in standby, press
u
STANDBY/ON
for about 5 seconds 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.
Do not pull out the power cord while conducting the settings. (The settings will be stored
when both the main zone and sub zone turn off. Turn off all zones before pulling out the
power cord.)

Certain listening modes or

When
Operation Mode
is set to
Basic
, the Pioneer-recommended settings are made and
not all of the functions can be used. To use all of the functions without restrictions, set
Operation Mode
to

Feels like there is no subwoofer EQ
effect.
The effect becomes less when the set frequency value of the crossover frequency is low.
When setting a high frequency value, the subwoofer EQ effect becomes stronger. How-
ever, setting a higher crossover frequency increases the share that the subwoofer bears
for low-frequency playback. For that reason, it is disadvantageous in terms of the phase
point of view. Set to your preference.
Professional Calibration EQ graphical output
Symptom
Remedy
The reverb characteristics graph
after EQ 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 character-
istics 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 mea-
surements.
EQ adjustments made using the
Manual MCACC setup do not appear
to change the reverb characteristics
graph after EQ calibration.
Despite level adjustments being made, the filters used for analysis may not display these
adjustments in the reverb characteristics graph after EQ calibration. However, these
adjustments are taken 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 measur-
able sound is output for display.
