Note that if you link a particular input to another, the "master" input cannot be linked to another channel. This also applies to
outputs.
In its simplest use, you can link one or more inputs or outputs to one other and use that to simultaneously change the delay of
all linked channels. Here inputs A, B & C have been linked to input D and a delay of 15ms has been applied to input D;-
As you can see, although the individual channels A, B & C have nothing entered, the delay display shows 15ms for all inputs.
In addition to this simple matched delay, channels linked to others can also have a delay entered and the total delay will equal
the delay entered for the "master" channel plus whatever delay is entered for that channel. Any changes to the "master" delay
will be tracked by any channels linked to it. In this example, Output channels 2, 3 & 4 are linked to output 1. Output two has its
own delay of 10ms, output three 20ms and output four 30ms. We add 10ms to output 1 and see the following;-
If we now increase the delay on Output one to 20ms we see this;-
