Introduction
The SRS CSE-07D Circle Surround
®
Digital Encoder enables audio professionals to
encode up to 6.1 channels of discrete program material (Left, Center, Right, Right
Surround, Center Surround, Left Surround, LFE). 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.
Based on an SRS patented advanced matrix system, Circle Surround encoded Lt/Rt
material is incredibly robust and suitable for either analog or digital distribution. It supports
quality bit rates as low as 40 kbps and delivers compelling home-theater audio performance
at compression rates of 96 kbps and above. Circle Surround is also compatible with a
variety of codecs and compression schemes. Sound designers, mixers and facilities
creating multichannel audio content will find the CSE-07D to be the most flexible and
powerful encoding solution available.
Surpassing the limitations of previous matrix encoders, the CSE-07D Circle Surround Encoder
supports current multichannel material, accepting up to 6.1 channels of discrete audio input for
two-channel Lt/Rt encoding. Circle Surround also provides the unique ability to localize specific
broadband audio signals in the Left or Right surround channel as individual sound sources.
Previous matrix encoders only allow for the encoding of Left, Center, Right and mono,
bandwidth limited, surround channels. Circle Surround now provides the capability to encode
Left, Center, Right, Right Surround, Center Surround, Left Surround and LFE channels. This
major breakthrough in matrix technology raises the potential for audio on all platforms – music,
film, television, games and Internet streaming.
Circle Surround encoded material is backwards compatible with all existing playback formats
from mono to 5.1 channel surround sound (i.e. Circle Surround 5.1 and Pro Logic II
®
)
decoding. Optimal performance, however, is achieved with a Circle Surround II decoder.
For monitoring purposes, the SRS CSD-07D Circle Surround Digital Decoder is the perfect
compliment to the SRS CSE-07D Encoder for professional studio environments. In
addition, the CSE-07D has two channels of analog outputs for backwards compatibility with
analog decoders such as the CSD-07.
