6.1.0.1
Example of implementing parallel inputs
In this example, the signal from the source is split and con-
nected to Level 1 Input 1 and Level 2 Input 1. The signal
routes available to get to the output devices are
In: Level 1 Input 1
Out: Level 1 Output 1
In: Level 2 Input 1
Out: Level 2 Output 1
The source signal can be routed through one or both output
devices. Each split of the source signal should be treated as a
separate input signal.

Loop Back
Loop back is a method that allows mid-switch processing of a
signal. The looped signal can be mixed with other signals,
have noise extracted from it, or be converted to a different sig-
nal type, all within an external processor, before reaching its
final destination.
Using loop back, several input signals can be processed, in
varying order, by the same external device. You can achieve
this by attaching the signals to input connectors on the
1YDM, and attaching the processor to one or more output con-
nectors and one or more input connectors. The signal can
then be routed from the matrix, through the processor, and
through the matrix again to its final output destination. No
new software is required for this application of your 1YDM.
Loop back is highly effective while working with signal modi-
fication devices such as line doublers, digital signal
processors, video effects, video character devices, and other
such equipment.
