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.

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 26 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 28).
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 88.2/96kHz 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 26 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.
