5 Listening to your system Phase Control technology provides coherent sound reproduction through the use of phase matching 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. Setting the Audio options There are a number of additional sound settings you can make using the AUDIO PARAMETER menu. The defaults, if not stated, are listed in bold. Important • Note that if a setting doesn't appear in the AUDIO PARAMETER menu, it is unavailable due to the current source, settings and status of the receiver.  Press PHASE to switch the P.CTL (Phase Control) ON or OFF. Note • 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, 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. 1 Press RECEIVER , then press AUDIO PARAMETER button. 2 Use / to select the setting you want to adjust. Depending on the current status/mode of the receiver, certain options may not be able to be selected. Check the table below for notes on this. 3 Use / to set it as necessary. See the table below for the options available for each setting. 4 Press RETURN to confirm and exit the menu. Setting/What it does Option(s) EQ (Acoustic Calibration EQ) Switches on/off the effect of Acoustic Calibration EQ. S.DELAY (Sound Delay) Some monitors have a slight delay when showing video, so the soundtrack will be slightly out of sync with the picture. By adding a bit of delay, you can adjust the sound to match the presentation of the video. ON OFF 0 to 500 ms (1 step : 5 ms) Default: 0 MIDNIGHT/LOUDNESSa The MIDNIGHT allows you to hear effective surround sound of movies at low volumes. The LOUDNESS is used to get good bass and treble from music sources at low volumes. M/L OFF MIDNIGHT LOUDNESS S.RTV (Sound Retriever)b When audio data is removed during the compression process, sound quality often suffers from an uneven sound image. The Sound Retriever feature employs new DSP technology that helps bring CD quality sound back to compressed 2-channel audio by restoring sound pressure and smoothing jagged artifacts left over after compression. OFFc ON DUAL MONOd Specifies how dual mono encoded Dolby Digital soundtracks should be played. CH1 - Channel 1 is heard only CH2 - Channel 2 is heard only CH1 CH2 - Both channels heard from front speakers F.PCM (Fixed PCM) OFF This is useful if you find there is a slight delay ON before OFF recognizes the PCM signal on a CD, for instance. When ON is selected, noise may be output during playback of non-PCM sources. Please select another input signal if this is a problem. 4 6 34 28
