Listening to your system 05 English Deutsch Français Italiano Nederlands Español Phase Control technology provides coherent sound reproduction through the use of phase matching1 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.

Listening with Acoustic Calibration EQ You can listen to sources using the Acoustic Calibration Equalization set in Automatically setting up for surround sound (MCACC) on page 29. Refer to these pages for more on Acoustic Calibration Equalization.

The MCACC indicator on the front panel lights when Acoustic Calibration EQ is active.2 Using surround back channel processing You can have the receiver automatically use 6.1 or 7.1 decoding for 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES), or you can choose to always use 6.1 or 7.1 decoding (for example, with 5.1 encoded material). With 5.1 encoded sources, a surround back channel will be generated, but the material may sound better in the 5.1 format for which it was originally encoded (in which case, you can simply switch surround back channel processing off). • With a 7.1-channel surround system, audio signals that have undergone matrix decoding processing through surround back channel processing to which the Up Mix function is added are output from the surround back speakers.

Each press cycles through the options as follows: • SB ON - Matrix decoding processing for generating the surround back component from the surround component is turned on. Note 1 Phase matching is a very important factor in achieving proper sound reproduction. If two waveforms are 'in phase', they crest and trough together, resulting 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. • If your subwoofer has a phase control switch, set it to the plus (+) sign (or 0°). However, the effect you can actually feel when PHASE CONTROL is set to ON on this receiver depends on the type of your subwoofer. Set your subwoofer to maximize the effect. It is also recommended you try changing the orientation or the place of your subwoofer. • Set the built-in lowpass filter switch of your subwoofer to OFF. If this cannot be done on your subwoofer, set the cutoff frequency to a higher value. • If the speaker distance is not properly set, you may not have a maximized PHASE CONTROL effect. • The PHASE CONTROL mode cannot be set to ON in the following cases: - When the PURE DIRECT mode is switched on. - When the headphones are connected. 2 You can't use Acoustic Calibration EQ with Stream Direct mode and it has no effect with headphones. 37 En
