This piece of equipment has been disposed of.

This is often referred to as VT 'P169' since in September 2009 it replaced the old VT P169 which was an actual P169. This is actually a slightly lower-quality matrix switcher.

Reference signal

Michael Cullen did an experiment in 2009, where a DA'ed 'YSTV Clock' video signal was put into the reference input: This allowed VT 8x4 to switch inputs. As clock is always on, and in some cases we need to use the unit outside of a show, the matrix is now fed as above, permanently. Magic DaVE B&B would also work, but this way, it doesn't need to be turned on.
