Crestron C2N-DAP8RC Digital Audio Processor with Room Control
Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 3
Movie Mode
The Movie mode is for use with VCRs, television shows, and all programs encoded
in Dolby Surround. The result is an enhanced soundfield 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.
• Center Width. This control allows center-channel sounds to be positioned
between the center speaker and the left/right speakers over a range of eight
steps. Step “3” uses a combination of all three front speakers to give the
best vocal imaging and most seamless soundstage presentation, and is
recommended for most recordings. Step “0” places all center sound in the
center speaker. Step “7” places all center sound equally in the left/right
speakers, just as in conventional stereo.
• Dimension. This control allows the user to gradually adjust the soundfield
either toward the front or the rear. This can be useful to help achieve the
desired balance from all the speakers with certain recordings that may
contain either too much or too little spatial effect. Step “3” is the
recommended setting, which has no effect on the sound. Steps “4” through
“6” gradually move the sound forward, and steps “2” through “0” move the
sound toward the surrounds.
• Panorama. This control extends the front stereo image to include the
surround speakers for an exciting “wraparound” effect with side-wall
imaging. It is particularly effective for recordings that have strong left- or
right-channel elements in the mix, since these are detected and accentuated
by the Panorama process.
All three of the above controls may be used alone or in any combination. After
experimenting with them on a few programs, it is easy to understand their effect and
which settings are preferable.
Dolby Digital EX
Dolby Digital EX creates six full-bandwidth output channels from 5.1 channel
sources by adding a rear center channel. This is done using a matrix decoder that
derives three surround channels from the two in the original recording. The center
rear is matrixed into the rear 2-channels of the 5.1 soundtrack, like what Pro Logic
does with the front three channels in the Pro Logic mode. The decoder takes the right
rear and left rear information, which also contains the center rear information, and
extracts the information so that the center rear channel is active. Thus, sound will be
heard out of the center rear speaker as well as the right rear and left rear speakers.
For best results, Dolby Digital EX should be used with movie soundtracks recorded
with Dolby Digital Surround EX.
DTS 5.1
DTS 5.1 is a multi-channel digital signal format developed by Digital Theater
Systems, Inc., that provides channels for the front left, right, and center, surround left
and right, and LFE. The process used by DTS produces audio tracks that closely
match the original master recording, with very little data compression.
