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.

RECEIVER

Switch on your system components and receiver.

Start by switching on the playback component (for

example a DVD player), your TV

have one), then the receiver (press

• 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 INPUT

SELECTOR dial.

Press S. DIRECT ( 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.

• See also Listening to your system on page 27 for

information on different ways of listening to sources.

Use the volume control to adjust the volume level.

Turn down the volume of your TV so that all sound is

coming from the speakers connected to this receiver.

Note

1 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.)

2 If you need to manually switch the input signal type press SIGNAL SEL (page 30).

3 • 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 27 if you need to do this) if you want multichannel surround sound.

4 Phase matching is a very important factor in achieving proper sound reproduction. If two waveforms are 'in phase', they crest and trough together, re-

sulting in increased amplitude, clarity and presence of the sound signal. If a crest of a wave meets a trough (as shown in the upper section of the diagram

above) then the sound will be 'out of phase' and an unreliable sound image will be produced.
