Problems When Using The Auto Mcacc Setup - Pioneer SC-LX73 Operating Instructions Manual

04 Basic Setup
• MCACC – The six MCACC presets are used for storing
surround sound settings for different listening
positions. Simply choose an unused preset for now
(you can rename it later in Data Management on
page 107).
• THX Speaker – Select YES if you are using THX
speakers (set all speakers to SMALL), otherwise leave
it set to NO.
4 Set the remote control to the receiver operation
mode, then select START.
5 Follow the instructions on-screen.
Make sure the microphone is connected, and if you're
using a subwoofer, make sure it is switched on and set to
a comfortable volume level.
6 Wait for the test tones to finish, then confirm the
speaker configuration in the GUI screen.
A progress report is displayed on-screen while the
receiver outputs test tones to determine the speakers
present in your setup. Try to be as quiet as possible while
it's doing this.
If no operations are performed for 10 seconds while the
speaker configuration check screen is being displayed,
the Full Auto MCACC Setup will resume automatically. In
this case, you don't need to select 'OK' and press ENTER
in step 7.
• With error messages (such as Too much ambient
noise! or Check microphone.), select RETRY after
checking for ambient noise (see Problems when
using the Auto MCACC Setup on page 44) and
verifying the mic connection. If there doesn't seem to
be a problem, you can simply select GO NEXT and
continue.

The configuration shown on-screen should reflect the
actual speakers you have.
Note
1 If the speaker is not pointed to the microphone (listening position) or when using speakers that affect the phase (dipole speakers, reflective
speakers, etc.), Reverse Phase may be displayed even if the speakers are properly connected.
2 • Depending on the characteristics of your room, sometimes identical speakers with cone sizes of around 12 cm will end up with different size
settings. You can correct the setting manually using the Manual speaker setup on page 109.
• The subwoofer distance setting may be farther than the actual distance from the listening position. This setting should be accurate (taking
delay and room characteristics into account) and generally does not need to be changed.
• If Full Auto MCACC Setup measurement results are incorrect due to the interaction of the speakers and viewing environment, we
recommend adjusting the settings manually.

• If you see an ERR message (or the speaker
configuration displayed isn't correct), there may be a
problem with the speaker connection.
If selecting RETRY doesn't work, turn off the power
and check the speaker connections. If there doesn't
seem to be a problem, you can simply use / to
select the speaker and / to change the setting
and continue.
• If Reverse Phase is displayed, the speaker's wiring
(+ and –) may be inverted. Check the speaker
connections.
– If the connections were wrong, turn off the power,
disconnect the power cord, then reconnect properly.
After this, perform the Full Auto MCACC procedure
again.
– If the connections were right, select GO NEXT and
continue.
7 Make sure 'OK' is selected, then press ENTER.
A progress report is displayed on-screen while the
receiver outputs more test tones to determine the
optimum receiver settings.
Again, try to be as quiet as possible while this is
happening. It may take 3 to 10 minutes.
8 The Full Auto MCACC Setup procedure is completed
and the Home Menu menu reappears automatically.
Be sure to disconnect the microphone from this receiver
upon completion of the Full Auto MCACC Setup.
The settings made in the Full Auto MCACC Setup should
give you excellent surround sound from your system, but
it is also possible to adjust these settings manually using
The Advanced MCACC menu on page 99 or The System
Setup and Other Setup menus on page 109.

Problems when using the Auto MCACC Setup

If the room environment is not optimal for the Auto
MCACC Setup (too much background noise, echo off the
walls, obstacles blocking the speakers from the
microphone) the final settings may be incorrect. Check
for household appliances (air conditioner, fridge, fan,
etc.), that may be affecting the environment and switch

them off if necessary. If there are any instructions
showing in the front panel display, please follow them.
• Some older TVs may interfere with the operation of
the microphone. If this seems to be happening,
switch off the TV when doing the Auto MCACC Setup.
