Introduction
The SRS CSD-07D Circle Surround ® Digital Reference Decoder is for use in
professional studio production, mastering and broadcast environments to
monitor audio, video and multimedia programs encoded with Circle Surround
(CS) and other matrix-encoded, two-channel (Lt/Rt) Surround Sound
systems. It can be distributed across two-channel carriers such as stereo
broadcast television (analog and digital), cable or satellite transmission, VHS
videotape, computer and console games, CDs, streaming media and two-
channel DVD soundtracks.
As a high-performance 5.1 or 6.1 multichannel decoder, the CSD-07D also
delivers superior performance for decoding of any Dolby Surround ® encoded
content (LCRS). The CSD-07D is a versatile tool for professionals to
accurately monitor the production of such program material and to evaluate
the previously matrix-encoded soundtracks of feature films being prepared
for distribution across consumer two-channel formats.
Aside from functioning as a reference monitor, the CSD-07D also features SRS
Labs’ Xtract ™ technology for use on mono, stereo or LCRS encoded Lt/Rt
signals. This function enables the repurposing of legacy material for newer
discrete or 5.1 Lt/Rt releases. The post process enhancements enable the
mixer to expand the sonic quality in addition to the number of channels
available. Mixers can now make any content fit into their 5.1 or 6.1 mix.
The SRS CSD-07D Decoder allows the user to monitor in six modes; CS
Cinema (for mixing and extracting Film and TV content), CS Music (for mixing
and extracting Music content), CS mono (for extracting mono material to 5.1 or
6.1), LCRS (for monitoring backwards compatibility to legacy LCRS decoders),
stereo or mono. This allows the mixer to review the mix in all standard playback
formats. The seventh mode, Test Mode, cycles pink noise throughout the
channels for calibration purposes. The SRS CSD-07D is the perfect
complement to the SRS CSE-07D Encoder.
