Mini Glossary for Sound Mode

Allows you to enjoy 5.1 (or 6) discrete channels of high quality digital audio from DTS program sources, such as DVDs and CDs, bearing the DTS trademark. DTS Digital Surround delivers up to 6 channels of transparent audio (i.e., identical to the original masters) and results in exceptional clarity throughout a true 360 degree sound field. The term DTS is a trademark of DTS Technology, LLC. Manufactured under license from DTS Technology, LLC.

The Dolby Digital surround format lets you enjoy up to 5.1 channels of digital surround sound from Dolby Digital program sources. If you play DVDs with the “ ” mark, you can enjoy even better sound quality, greater spatial accuracy, and improved dynamic range.

When playing recordings of live or classical music, this mode provides a feeling similar to actually being in a small concert hall.

When playing recordings of live or classical music, this mode provides a feeling similar to actually being in a large concert hall.

This mode provides a three dimensional effect similar to that of a movie theater.

II

Dolby Pro Logic II creates five full-bandwidth output channels from two-channel sources. This is done using an advanced, high-purity matrix surround decoder that extracts the spatial properties of the original recording without adding any new sounds or tonal colorations. Pro Logic II offers the following five modes:

PROLOGIC Emulation mode:

The Pro Logic Emulation mode offers users the same robust surround processing as original Pro Logic, in case the source content is not of optimum quality, or if there is a desire to hear the program more “as it used to be.” When this mode is used, it is called Pro Logic, as before. There is no “Pro Logic I” mode. The Pro Logic emula- tion mode is optional.

MOVIE mode:

The Movie mode is for use with stereo television shows and all programs encoded in Dolby Surround. The result is enhanced sound field directionality that approaches the quality of discrete 5.1-channel sound.

MUSIC mode:

The Music mode is for use with any stereo music recordings, and provides a wide and deep sound space. The Music mode includes controls that allow the sound to be tailored to individual listening tastes.

VIRTUAL mode:

The Virtual mode is usually used when Pro Logic II is connected to a virtual process for speaker use. However, there might be some virtualizers for which this mode does not produce the intended result. For those virtualizers, Movie mode may give the best surround effect. Virtual mode is designed to be used with the virtual process developed by Dolby Laboratories. The Pro Logic II mode should be called only “Pro Logic II” so the Virtual name can be reserved to describe the speaker virtualization process itself.

MATRIX mode:

The Matrix mode is the same as the Music mode except that the directional enhancement logic is turned off. It may be used to enhance mono signals by making them seem “larger.” The Matrix mode may also find use in auto systems, where the fluctuations from poor FM stereo reception can otherwise cause disturbing surround signals from a logic decoder. The ultimate “cure” for poor FM stereo reception may be simply to force the audio to mono.

SURROUND OFF (2CH STEREO)

Outputs the sound from the front left and right speakers and subwoofer. Standard two channel (stereo) sources completely bypass the sound field processing. This allows you to play any source using only the front left and right speakers and subwoofer. You can select SURROUND OFF by pressing BY PASS on the remote control.
