This provides continuity of sound instead of a stage speaker fading down and a surround speaker coming up in level. Encoding of additional channels can be easily accomplished with the Circle Surround studio encoder which is capable of 5 separate channels on the 2 digital surround channels. The CS-3X is designed for future formats. The CS-3X contains 3 full octave equalizers to equalize each of the surround channels for a smooth playback response. Also, a front control button will manually select the desired format for normal split-surround or 3 channel surround operation.
Mono surround information from optical stereo soundtracks feeds all three channels simultaneously.
The transition is automatic if the logic circuits from the CS-3X are tied to the pulse format terminals of any stereo processor. Internal level adjust controls allows the installer to match the levels of the surround outputs and the bypass signals.
