In earlier processors we allowed Trifield to operate for configurations with no Centre channel. However we felt it was not of any interest because it amounts, in that case, to a width control in Stereo which we don't provide. At some point we changed the processors to revert to Stereo in the Trifield-no-Centre case.

We really don't think that there is an error in current Trifield code (G61, G68, 861). There is thorough fully-automated process to check each code build. However to be certain we will schedule a check. We have rechecked 568 and 568.2 and they are to spec.

In Trifield, Width changes the signals fed to L & R and the degree to which this is audible will very much depend on the content. Strictly the Width control responds to the magnitude of S = (L-R). To hear this best use open spacious recordings.
