Using the Documentation

The DC-2 can be easily integrated with the various types of loudspeaker systems currently available, including those that are THX certified. By adhering to the rigorous THX Ultra specification, the DC-2 includes THX enhancements for optimizing playback of matrix-encoded film soundtracks as well as Surround EX for those recorded in the Dolby Digital and DTS discrete formats. These enhancements ensure that film soundtracks, which are typically mixed for the acoustics of large theaters, sound as the filmmak- ers intended when played back in the relatively small environment of a home theater.

Because the DC-2 is designed to be customized for your system and your listening space, the information required for installation is extensive.

The Owner's Manual is designed to assist you in installing, calibrating and operating the DC-2. It should be used in conjunction with the remote control when configuring the system to perform optimally in your environment. This manual was written with the underlying assumption that the installer is familiar with audio/video system installation. An Installation Worksheet is provided at the end of this manual for documentation of the settings arrived at during the calibration procedure.

Glossary of Terms	Although the DC-2 performs very complex signal processing, a great deal
	of effort has gone into making the technology behind the effects as transpar-
	ent as possible to the user. To understand the overall organization of the
	unit, it is helpful to define those few terms which are unique to the DC-2.
	AC-3 FX The term AC-3 FX (Dolby Digital Effects) is used to describe all of
	the effects which are compatible with Dolby Digital input signals. Any AC-
	3-capable software and/or source components should be labeled with a
	badge, similar to the one on the DC-2 front panel (AC-3 and DTS versions).
	DTS FX The term DTS FX (Digital Surround Effects) is used to describe all
	of the effects which are compatible with DTS Digital Surround input
	signals. Any DTS-capable software and/or source components should be
	labeled with a badge, similar to the one on the DC-2 front panel (AC-3 and
	DTS versions).
	Downmix describes the process of creating a two-channel output from a
	multichannel (>2) signal. Downmixing is necessary to maintain compatibil-
	ity between multichannel formats and devices such as Dolby Digital and
	DTS, and two-channel formats and devices, such as stereo tape decks and
	VCRs.
