Some video sources offer both composite and S-video outputs. In this case, S-video will yield
superior results for video sources that are inherently of the S-video type (i.e., have separate
Y and C signals). Such video sources include DVD, Super-VHS (
S -VHS), and digital satel-
lite (e.g., DSS). For sources, such as laserdisc, that are inherently composite, then either the
composite or S-video outputs may yield the best results, depending upon whether the video
source or the projector/TV monitor has the superior composite-to-S-video converter (comb
filter). For such composite sources, the user is encouraged to experiment to determine
whether composite or S-video gives the best results.
*Video switching with the Signature requires the optional SwitchMaster professional-grade 150 Megahertz video
switcher (see Chapter XI: “Options”). After installing the SwitchMaster (see Chapter III: “C. Hookup”), and pro-
gramming Audio/Video links (see Chapter III: “F. Programming Audio/Video links”), video switching with the
TheaterMaster Signature follows the same procedure described above. With the SwitchMaster, however, the composite
connection from the SwitchMaster’s “Main” video outputs to the projector/TV monitor is optional, due to Switch-
Master’s internal composite-to-S-video converter (comb filter). This comb filter makes it possible to leave your projec-
tor/TV monitor permanently switched to S-video, and to do
all
video switching (among both composite and
S-video inputs) with the SwitchMaster. The composite connection from SwitchMaster’s Tape/Mon outputs to your
VCR is needed, however, since SwitchMaster’s Tape/Mon outputs do not have their own, dedicated comb filter.
F. Choosing a playback mode:
1. “Normal” PCM digital or analog source material (non DTS or Dolby Digital):
Choosing a playback mode (e.g., Pro Logic, Matrix, Mono-Enhanced, or Stereo) is
accomplished by pressing
Surround , Matrix, Stereo , or Mono , respectively, on page 2
of the remote control’s TheaterMaster device.
The Surround button initiates Dolby Pro Logic surround-sound decoding, and is
intended for use with source material that is surround-sound encoded. (You may not
always know whether a given program is surround-sound encoded or intended to be
played back in normal stereo. Experimentation will determine which sounds best.)
When Dolby Pro Logic decoding is selected using the
Surround
button, the bottom-
most circle on the source indicator (daisy pattern) will illuminate (see figure, below). This
bottom circle indicates the presence of a mono surround signal. This pattern distinguish-
es Dolby Pro Logic decoding from normal stereo, and from Dolby Digital sources that
have stereo surrounds. (See section “2. Dolby Digital source material” below).
The
Matrix
button is designed to provide enhanced enjoyment of stereo source material.
Matrix mode implements a standard Hafler matrix for the surround speakers (LS = L-R,
RS = R-L). In addition, a small amount of delay is added to the surrounds. This mode is
able to extract the sound field ambiance that is naturally embedded in a great many stereo
recordings, particularly those recorded with a single stereo microphone. It can also be
desirable on some multi-tracked music material and for stereo movies not recorded in
Dolby Surround. Matrix mode is compatible with HDCD playback.
(Note: Matrix mode
cannot be selected in “3Stereo” mode, in which the surround speakers have been de-activated.)
The
Stereo
button is intended for music and other stereophonic source material. With a
digital source, in Stereo mode, TheaterMaster functions as an ultra-high-performance,
audiophile D-to-A converter. On the Ovation and
Signature, balanced stereo outputs are
enabled, and HDCD source material is automatically detected and decoded.
