05 Listening to your system 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).

The default setting is on and we recommend leaving Phase Control switched on for all sound sources. RECEIVER SLEEP DIMMER PHASE INPUT SELECTOR DD • Press PHASE (PHASE CONTROL) to switch on phase correction. Using Midnight and Loudness The Midnight listening feature allows you to hear effective surround sound of movies at low volume levels. The effect automatically adjusts according to the volume at which you're listening. The Loudness listening feature can be used to get good bass and treble from music sources at low volume levels. • Press MIDNIGHT (MIDNIGHT/LOUDNESS) to switch between MIDNIGHT, LOUDNESS, and OFF. Enhancing dialog • Default setting: OFF The Dialog Enhancement feature localizes dialog in the center channel to make it stand out from other background sounds in a TV or movie soundtrack. • Press DIALOG (DIALOGUE ENHANCEMENT) to switch dialog enhancement on or off. Using the tone controls Depending on what you are listening to, you may want to adjust the bass or treble using the front panel tone control.2 1 Press TONE to select the frequency you want to adjust. Press to switch between BASS and TREBLE. 2 Use the MULTI JOG dial to change the amount of bass or treble as necessary. Wait about five seconds for your changes to be input automatically. 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. 2 The tone controls are only available when Stereo or Front Stage Surround Advance mode are selected (except when STEREO is selected using AUTO SURROUND). 26 En
