11. AL VIDEO DEVICES Digital video sources and output devices are connected to an SDI switcher or matrix through the BNC type connectors on the back of the machine SDI signals are very high frequency carrying signals and are very sensitive to cable quality and length They are vulnerable to the cliff effect in which the signal will look good after travelling a certain cable length but when the line is only slightly extended the signal crashes completely without any warning Therefore keep the length of the cables at the absolute minimum necessary The machines described in this manual have built in provisions to minimize signal loss and distortions Both the switcher and the matrices have built in cable equalization circuitries to compensate for high frequency cable losses as well as time base correction reclocking circuitries which eliminate signal jitter cumulated along the cables The reclocking circuitry regenerates the signal s clock pulses eliminating signal instability and potential cliff effects With the built in equalization and reclocking circuitries the switcher and matrices can be operated at cable lengths and distances of hundreds of meters when high quality cables are used Turning On the Machine NOTES 1 The machine should only be turned on after all connections are completed and all source devices have been turned on Do not attempt to connect or disconnect any video signal while it is on 2 The socket
