3.3 Making AV Routings or "Ties" from Front Panel

To make the unit as convenient and intuitive as possible the VSM matrix allows you to
make ties starting from the input channel's point of view or from the output.
In most cases audio and video from the same input are routed to a given output
(synchronized switching). But the Matrix can route the audio and video independently.
You can use the VID and AUD buttons on the front panel to route just one or the other,
or if both buttons are lit, to route synchronously.
3.3.1 Making a tie starting from the output
This is the most natural way of making connections since each output gets is signal
from only one input.
Press one of the output channel buttons. That button will light up and the

inputs routed from that output will light up.
At this point if you change your mind, and do not want to make any changes,

just hit SET. If you want to change to another output channel, use either the
up and down ( ▲▼) buttons to walk through other outputs ; or just select
another output channel.
To route the output to a different input than the one currently connected to,

hit the "candidate" input channel number. This does not actually make the
connection; the new input channel will be blinking. Again if you change your
mind, either hit the same blinking button (it will stop blinking), or hit another
input channel. When you are sure you have selected the input channel you
desire, hit SET.
To blank the output, press the currently lit input button position and then hit

SET
Note that once you enter the channel routing mode from the front panel, if

you do not hit any buttons for approximately 10 seconds, the system will exit
this mode without any user interaction.
3.3.2 Making a tie starting from the input
The procedure is similar to the above but a particular input can be routed to more than
one output or none at all!
Press one of the input channel buttons. That button will light up and ALL the

outputs routed from that input will light up.
If you want to change to another input channel, use either the up and down

(▲▼) buttons to walk through other inputs; or just select another input
channel.
To route the selected input to single or multiple outputs, press the output

buttons. Again, these new outputs are only "candidates" (will be blinking) and
will not be routed until you hit SET.
