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.
1 Switch on your system components and receiver.
Start by switching on the playback component (for
example a DVD player), your TV 1 and subwoofer (if you
have one), then the receiver (press RECEIVER ).
• Make sure the setup mic is disconnected.
2 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.
2
3 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 28 for
information on different ways of listening to sources.
4 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.
Better sound using Phase Control
This receiver’s Phase Control feature uses phase
correction measures to make sure your sound source
arrives at the listening position in phase, preventing
unwanted distortion and/or coloring of the sound (see
illustration below).
Phase Control technology provides coherent sound
reproduction through the use of phase matching
4
for an
optimal sound image at your listening position. The
default setting is on and we recommend leaving Phase
Control switched on for all sound sources.
• Press PHASE ( PHASE CONTROL ) to switch on phase
correction.
The PHASE CONTROL indicator on the front panel lights.
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 31).
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 28 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.
