Selecting this position will be effective when you must listen to a source in extremely low level. MIN: Adjusts the delay between the main sounds (at the main channels) and dialog etc. The larger the value, the later the dialog etc. This is for making sounds from the left main, center and right main speakers reach your listening position at the same time by delaying the sound from the center speaker if the distance from the center speaker to your listening position is shorter than the distance from the left or right main speaker to your listening position. 3. LFE LEVEL (Adjusting the output level at the LFE (low frequency effect) channel) Control range: ­14 dB to 0 dB (in 2 dB step) Preset value: 0 dB * This adjustment is effective only when the Dolby Digital (AC3) is decoded and the signals of selected source encoded with the Dolby Digital (AC-3) contain LFE signals. 2. DYNAMIC RANGE (Adjusting dynamic range) Choices: MAX/STD/MIN Preset position: MAX * This adjustment is effective only when the Dolby Digital (AC-3) is decoded. Adjusts the output level at the LFE (low frequency effect) channel. If the LFE signals are mixed with signals at other channels to output them from the same speakers, the ratio of LFE signal level to the level of other signals are adjusted. (See page 6 for details about the LFE channel. ) MAX: "Dynamic range" is the difference between the maximum level and the minimum level of sounds. Sounds on a movie originally designed for movie theaters feature very wide dynamic range. Dolby Digital (AC-3) technology can bring the original sound track into a home audio format with this wide dynamic range unchanged. In this position, a source encoded with the Dolby Digital (AC-3) is reproduced in the original sound track's wide dynamic range providing you with powerful sounds like a movie theater. Digital input signal from the COAXIAL terminal 2. Analog input signal 0 ­dB Adjust to the desired output level. 8 If desired, adjust the BASS, TREBLE, BALANCE controls, etc. (refer to page 31) and use the digital sound field processor.

When you select a button other than TAPE/MD MONITOR, make sure that the "TAPE MONITOR" indicator is not illuminated on the display. q If you select the input selector button for a video source without canceling the selection of TAPE/MD MONITOR, the playback result will be the video image from the video source and the sound from the audio tape (or MD etc. ). q Once you play a video source, its video image will not be interrupted even if the input selector button for an audio source is selected. q When you select an input source by pressing the corresponding input selector button, the DSP program (or the state of no DSP program is used) which was used when the same input source was selected the last time will automatically recalled. ANALOG: In this mode, only analog input signal is selected even though digital signal is input at the same time. [. . . ] There are buzzing and whining noises (especially in the evening).
