Select CINEMA to optimize for Dolby Surround encoded movie soundtracks including increased surround separation and full-bandwidth surround channel frequency response.

Select MUSIC to optimize for musical recordings. When the MUSIC mode is selected, three additional parameters will be available on the OSD screen. Use the UP/DOWN buttons on the remote to select a parameter. Use the +/– buttons to change the selected parameter as follows:

•PANORAMA: The Panorama option extends the front stereo image to include the surround speakers for a dramatic “wraparound” effect. The options are OFF or ON.

•DIMENSION: The Dimension option allows you to gradually adjust the soundﬁeld towards the front or towards the rear. There are seven incremental settings from 0 to 6. A setting of 0 shifts the soundﬁeld towards the rear for maximum surround effect. A setting of 6 shifts the soundﬁeld to the front for minimum surround effect. The default setting of 3 provides a “neutral” balance between the two extremes.

•CENTER WIDTH: The Center Width option allows you to spread the signal intended for the center speaker to the left and right front speakers, widening the perceived soundﬁeld. There are eight incremental settings from 0 to 7. With the default setting of 3, there is no center width spreading and all of the center channel information is sent to the center speaker. The maximum setting of 7 shifts all of the center channel signal to the left and right speakers, essentially muting the center speaker and maximizing the soundﬁeld width. Other settings provide incremental steps between the two extremes.

Select GAME to optimize for Dolby Surround encoded video games.

Select PRO LOGIC for original Dolby Pro Logic decoding. Typically, Pro Logic II (Cinema or Music modes) will provide better surround performance, even with older source material. Original Pro Logic mode provides 5.1 channel surround sound, even on 6.1/7.1 channel systems.

When you have completed all the desired adjustments, highlight the INPUT SETUP MENU line at the bottom of the screen and press the ENTER button to return to the INPUT SETUP menu (or just press the ENTER button).

DTS Neo:6

When DTS Neo:6 is selected as the default surround mode on the INPUT SETUP menu, there are additional option settings and parameters available to optimize the surround decoding for various types of recordings, music or movie soundtracks. DTS Neo:6 uses matrix decoding algorithms to derive a center channel and surround channels from 2-channel source material.

In DTS Neo:6 mode, there will only be one choice available on the sub- menu: selecting CINEMA or MUSIC modes. Use the +/– buttons on the remote to change the settings.

•Select CINEMA to optimize the DTS Neo:6 decoding for movie soundtracks.

•Select MUSIC to optimize the DTS Neo:6 decoding for musical recordings.

When you have completed the setting, highlight the INPUT SETUP MENU line at the bottom of the screen and press the ENTER button to return to the INPUT SETUP menu (or just press the ENTER button).

Speakers and Audio

This section of the setup process covers items concerning audio reproduction such as the number of speakers, bass management including subwoofer crossovers, establishing equal output levels for all channels, delay settings, and tone contour settings.

Understanding Speaker Conﬁguration

Home theater systems vary in the number of speakers and the bass capabilities of those speakers. This receiver offers surround modes tailored to systems with various numbers of speakers and bass management features which send bass information to the speaker(s) best able to handle it – subwoofers and/or large speakers. For optimum performance, you must tell the receiver the number of speakers in your system and how bass should be distributed among them.

Note: There are two types of bass in a surround system. The ﬁrst is bass recorded in each of the main channels (front, center, and surround). This bass is present in all recordings and soundtracks. In addition, Dolby Digital 5.1 and DTS 5.1 recordings may have a Low Frequency Effects (LFE) channel – the .1 channel. This LFE channel, typically played by a subwoofer, is used for effects such as explosions or rumble. The use of the LFE channel will vary from soundtrack to soundtrack. Recordings that are not encoded in Dolby Digital or DTS do not have the LFE channel.

The following conﬁguration instructions refer to LARGE and SMALL speakers, referring more to their desired bass conﬁguration than their physical size. Speciﬁcally, use the LARGE setting for speakers that you want to play deep bass signals. Use the SMALL designation for speakers that would beneﬁt from having their bass sent to more capable speakers. The bass management system redirects bass information away from

all SMALL speakers and sends it to the LARGE speakers and/or the SUBWOOFER. It may be useful to think of LARGE as “full-range” and SMALL as “high-pass ﬁltered.”

Four typical examples of the many possible system conﬁgurations illustrate the principles behind bass management:

•Five LARGE speakers and subwoofer: This system requires no bass redirection. All ﬁve speakers play the normal bass recorded in their respective channels. The subwoofer plays only the LFE channel bass. Depending on the soundtrack, there may be minimal use of the LFE channel, so the subwoofer would be under utilized. Meanwhile
