To prevent a fire or shock hazard, do not place any container filled with liquid near this equipment (such as a vase or flower pot) or expose it to dripping, splashing, rain D3-4-2-1-3_B_En or moisture. Before plugging in for the first time, read the following section carefully. The voltage of the available power supply differs according to country or region. [. . . ] ⷠPURE DIRECT ­ Analog and PCM sources are heard without any digital processing. ADVANCE ­ Use to provide a rich surround sound effect directed to the center of where the front left and right speakers sound projection area converges. 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. Use the Stream Direct modes when you want to hear the truest possible reproduction of a source. 2 There are cases where a brief noise is heard before playback of sources other than PCM. Listening to your system 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). 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. 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. It is also recommended you try changing the orientation or the place of your subwoofer. 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. Listening to your system There are a number of additional sound settings you can make using the AUDIO PARAMETER menu. [. . . ] So what sounds "normal" can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. to establish a safe level: · Start your volume control at a low setting. ⷠSlowly increase the sound until you can hear it comfortably and clearly, and without distortion.
