Advanced Setup—Continued

3-5. LFE Level

■a. Dolby Digital

With this setting you can adjust the level of the LFE (Low Frequency Effects) channel for Dolby Digital sources in 1 dB steps from –10 dB to 0 dB (default is 0 dB).

If you find that the low-frequency effects are too loud when playing Dolby Digital sources, lower this setting as necessary.

■b. DTS

With this setting you can adjust the level of the LFE (Low Frequency Effects) channel for DTS sources in 1 dB steps from –10 dB to 0 dB (default is 0 dB).

If you find that the low-frequency effects are too loud when playing DTS sources, lower this setting as neces- sary.

3-7. Theater-Dimensional

These settings are used with the Theater-Dimensional listening mode.

■a. Listening Angle

With this setting you can specify the angle of the front left and right speakers relative to the listening position. Processing for the Theater-Dimensional listening mode is based on this setting. Ideally, the front left and right speakers should be equidistant from the listening posi- tion and at an angle close to one of the two available set- tings.

3-6. Mono

■a. Academy Filter

Early movies had a mono soundtrack that suffered from audible hiss and a poor high-frequency response due to the quality of the film. To improve matters, the high-fre- quencies were boosted before being recorded onto film, and then attenuated to their original levels during play- back in the movie theater. Some old movies have been transferred to newer distribution media without the high- frequencies being attenuated, creating a harsh sound with pronounced hiss. With the Academy Filter function, which is based on the playback techniques used in those days, you can attenuate the high-frequencies to their original levels and enjoy the movie as it was intended to be heard.

On: Academy Filter on.

Off: Academy Filter off (default).

■b. Input Channel

With this setting you can specify how 2-channel sources are handled in the Mono listening mode.

AUTO L+R: The front left and right speakers output the same mix of the left and right channels (default).

Left: The front left and right speakers output the sound recorded in the left channel. Use this option with material that has different languages recorded in the left and right channels.

Right: The front left and right speakers output the sound recorded in the right channel. Use this option with material that has different languages recorded in the left and right channels.

70

20º: Select if listening angle is 20 degrees.

40º: Select if listening angle is 40 degrees (default).

■b. Center

With this setting you can specify whether or not you’re using a center speaker. If you are, the center channel sound will be output by the center speaker when using the Theater-Dimensional listening mode. This reduces the workload of the front left and right speakers, and cre- ates a more articulate sound space. In this case, the set- tings for the distance between the listening position and each individual speaker (see page 43), and the level of each speaker (see page 44) are important, so be sure to set them.

On: Select if using a center speaker.

Off: Select if not using a center speaker (default).

■c. Front Expander

With the Front Expander function you can broaden the width the front stereo image. This can be useful with nar- row listening angles of 20 degrees or less.

On: Front Expander function on.

Off: Front Expander function off (default).

■d. Virtual Surr Level

With this setting you can adjust the level of the virtual surround sound from –3 dB to +3 dB (default is 0 dB). If the clarity is poor, or the effect sounds unnatural, you may be able to improve it by lowering this setting.

■e. Dialog Enhance

With this function you can improve the clarity of the cen- ter channel, which usually contains dialog.

On: Dialog Enhance function on.

Off: Dialog Enhance function off (default).

The procedure for changing these settings is provided on page 68.
