P169s are 8x4 video matrix switchers. IE they can simultaneously send any of eight sources to any of four outputs. Crucially (because each of the eight inputs is buffered) the same input can be sent to two, three or four destinations - this couldn't be achieved by simply having a mechanical switch. | P169s are 8x4 video matrix switchers.

The P169 can be controlled via RS232 and so which input feeds each of the four outputs can be dictated remotely. | The P169 can be controlled via RS232 and so which input feeds each of the four outputs can be dictated remotely. | ||

**Ideally we would like to be able to change these names so that the director can easily see which each of the eight inputs is, without resorting to labelling the side of the monitor with LX tape. | **Ideally we would like to be able to change these names so that the director can easily see which each of the eight inputs is, without resorting to labelling the side of the monitor with LX tape. | ||

*P169's may be sensitive to heat - Previous shuffling in the rack to allow for more air circulation seems to have stopped anything else happening to them. | *P169's may be sensitive to heat - Previous shuffling in the rack to allow for more air circulation seems to have stopped anything else happening to them. | ||
