Symptoms Remedies

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 47). If the noise

level cannot be kept low enough, you will have to set up the surround sound manually

(page 100).

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 Speaker Setting on page 101, and use the ALL (Keep SP System) option for

the Auto MCACC menu in Automatic MCACC (Expert) on page 92 if this is a recurring

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-LX87 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) on page 46).

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 unplug-

ging 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.)

Symptoms Remedies

Certain listening modes or

HOME MENU items cannot be

selected.

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 Expert (see Operation Mode Setup on page 48).

Professional Calibration EQ graphical output

Symptoms Remedies

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.

Display

Symptoms Remedies

The display is dark or off. Press DIMMER repeatedly to select a different brightness.

The OSD screen is not displayed. The on-screen display is not displayed unless this receiver’s HDMI OUT 1 or HDMI OUT

2 terminal is connected to the TV by HDMI cable. If the TV does not support HDMI, watch

this receiver’s front panel display when performing operations and making settings.

Depending on the type of video input signal (4K, 3D, etc.), the on-screen display may not

be displayed.

You can’t get DIGITAL to display

when using SIGNAL SEL.

Check the digital connections and make sure that the digital inputs are assigned cor-

rectly (see The Input Setup menu on page 47).

2 DIGITAL or DTS does not light

when playing Dolby/DTS software.

These indicators do 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 indica-

tors 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 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.

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.
