Available on special DVD, LD and audio-only discs, DTS provides up to five separate main audio channels and a special dedicated low-frequency channel. Dolby Pro Logic II is the latest version of Dolby Laboratory's benchmark surround technology that decodes full-range, discrete left, center, right, right surround and left surround channels from either matrix surround-encoded programs or conventional stereo sources. The Dolby Pro Logic II Movies mode is optimized for movie soundtracks, while the Pro Logic II Music mode should be used with musical selections. The Pro Logic II Emulation mode re-creates original Pro Logic processing for those who prefer that presentation. Logic 7 is an advanced mode that extracts the maximum surround information from either surround-encoded programs or conventional stereo material. The Logic 7 C, or Cinema, mode should be used with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers increased center-channel intelligibility, and more accurate placement of sounds with fades and pans that are much smoother and more realistic than with other decoding techniques. The Logic 7 M, or Music, mode should be used with analog or PCM stereo sources. Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7 modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact. Uses the information contained in a surround-encoded or two-channel stereo program to create center-channel information. In addition, the information that is normally sent to the rear-channel surround speakers is carefully mixed in with the front-left and front-right channels for increased realism. Use this mode when you have a center channel speaker but no surround speakers. The Theater mode creates a sound field that resembles the acoustic feeling of a standard live performance theater. The two Hall modes create sound fields that resemble a small (Hall1) or medium-sized (Hall 2) concert hall. When only the two front-channel loudspeakers are used, Harman's patented VMAx mode delivers a threedimensional sound space with the illusion of "phantom speakers" at the center and surround positions. The VMAx N, or Near Field, mode should be selected when your listening position is less than five feet from the speakers. The VMAx F, or Far Field, mode should be selected when your listening position is greater than five feet from the speakers. The VMAx modes are also available using the Headphone Jack 4. When headphones are being used, the Far Field mode will appear to push the sound field away from your ears, reducing the "inside the head" sensation often experienced when using headphones. This mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Ideal for playing music in situations such as a party, it places the same signal at the front-left and surround-left, and front-right and surround-right speakers. The center channel is fed a summed mono mix of the in-phase material of the left and right channels. These modes turn off all surround processing and present the pure left- and right-channel presentation of two-channel stereo programs. The Stereo-Direct (Bypass) mode may only be used with analog source inputs, as it preserves the analog format of the audio signal for its entire path of travel through the receiver to the speaker and subwoofer outputs, bypassing all digital processing. Digital bass management is not available in Stereo-Direct mode. The Stereo-Digital mode can be used with either an analog or digital input, as the signal undergoes digital bass management to optimize the distribution of the low frequencies between the main speakers and a subwoofer.
