5 minute guide

• With error messages (such as

Too much ambient

noise!

Check Microphone.

) select

RETRY

after

checking for ambient noise (see

Problems when

using the Auto MCACC Setup

below) 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.

If you see an error message (

ERR

) in the right side

column (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 number for surround back) and continue.

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 for Channel Level, Speaker
Distance, Standing Wave and Acoustic Cal EQ.

Again, try to be as quiet as possible while this is
happening. It may take 3 to 7 minutes.

The Auto MCACC Setup has finished! Press RETURN

to go back to the System Setup menu.

Be sure to disconnect the microphone from this receiver
upon completion of the Auto MCACC setup.

The settings made in the Auto MCACC Setup should give
you excellent surround sound from your system, but it is
also possible to adjust these settings manually using the
System Setup menu (starting on page 38).

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.

Playing a source

Here are the basic instructions for playing a source (such
as a DVD disc) with your home theater system.

Switch on your system components and receiver.

Start by switching on the playback component (for
example a DVD player), your TV

and subwoofer (if you

have one), then the receiver (press



RECEIVER

• Make sure the setup mic is disconnected.

Select the input source you want to play.

You can use the input source buttons on the remote
control,

INPUT SELECT

, or the front panel controls.

Press AUTO/DIRECT (AUTO SURR/STREAM

DIRECT) to select ‘AUTO SURROUND’ and start

playback of the source.

If you’re playing a Dolby Digital or DTS surround sound
DVD disc, you should hear surround sound. If you are
playing a stereo source, you will only hear sound from the
front left/right speakers in the default listening mode.

Note

1 If you’re using the front panel display, the diagram in

Listening to Surround Sound

on page 8 indicates (in bold) how each speaker is displayed.

2 You can also choose to view the settings from the MCACC Data Check screen. See

Automatic MCACC (Expert)

on page 38 for more on this.

3 • 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 47.

• 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 Auto MCACC Setup measurement results are incorrect due to the interaction of the speakers and viewing environment, we recommend adjusting

the settings manually.

4 Make sure that the TV’s video input is set to this receiver (for example, if you connected this receiver to the

VIDEO 1

jacks on your TV, make sure that the

VIDEO 1

input is now selected).

5 If you need to manually switch the input signal type press

SIGNAL SEL

(page 32).

6 • You may need to check the digital audio output settings on your DVD player or digital satellite receiver. It should be set to output Dolby Digital, DTS and
88.2 kHz / 96 kHz PCM (2 channel) audio, and if there is an MPEG audio option, set this to convert the MPEG audio to PCM.

• Depending on your DVD player or source discs, you may only get digital 2 channel stereo and analog sound. In this case, the receiver must be set to a

multichannel listening mode (see

Listening in surround sound

on page 29 if you need to do this) if you want multichannel surround sound.
