05 Listening to your system Using Stream Direct Use the Stream Direct modes when you want to hear the truest possible reproduction of a source. All unnecessary signal processing is bypassed. AUTO/ STEREO/ BD MENU DIRECT A.L.C. STANDARD ADV SURR • While listening to a source, press AUTO/ DIRECT to select Stream Direct mode. • AUTO SURROUND - See Auto playback on page 33. • DIRECT - Sources are heard according to the settings made in the Surround Setup (speaker setting, channel level, speaker distance), as well as with dual mono settings.1 You will hear sources according to the number of channels in the signal. • PURE DIRECT - Analog and PCM sources are heard without any digital processing. Using the Sound Retriever 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.2 RECEIVER SLEEP TV SOURCE CONTROL RECEIVER INPUT SELECT INPUT HDD 1 DVD 2 VCR 3 DISP S.RETRIEVER SB CH CH SELECT EQ 4 5 6 CH MIDNIGHT SPEAKERS LEV 7 8 9 DIMMER LEV PHASE CH SHIFT • Press RECEIVER , then press S.RETRIEVER to switch the sound retriever on or off. 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). During multichannel playback, LFE (LowFrequency Effects) signals as well as lowfrequency signals in each channel are assigned to the subwoofer or other the subwoofer and the most appropriate speaker. At least in theory, however, this type of processing involves a group delay that varies with frequency, resulting in phase distortion where the low-frequency sound is delayed or muffled by the conflict with other channels. With the Phase Control mode switched on, this receiver can reproduce powerful bass sound without deteriorating the quality of the original sound (see illustration below).
