To check which input is routed to an output, press the
output key.
The input is illuminated.
The distribution matrix remains in status mode after a status
check is performed.

Disconnecting a Signal on a Level
Disconnecting a signal removes the input signal going to an
output device(s) without switching a new input signal to it.
This operation is different than making a switch. When a sig-
nal is disconnected, no other part of the distribution matrix is
affected. Disconnecting an input or output breaks the signal
connection(s) between the input and the output(s) it is routed
to on the specified level.
To disconnect an input or output:
1.
Hold down <Cancel> and press <Change>. The Change
LED begins flashing.
2.
Press a Matrix key to select a level.
Note:
If you do not specify a level, the input or output will
be disconnected on all levels.
3.
Press the key(s) of either the input(s) or output(s) you
want to disconnect.
Multiple inputs and outputs can be specified. Be aware
that specifying an input disconnects it from all outputs;
specifying an output disconnects it from its inputs but
does not affect any other outputs receiving that input.
4.
Press <Take>. The disconnection takes place and the
1YDM returns to status mode.
To check if the output was disconnected from the input:
While in status mode, press the input that was routed to that
output. The LED above the disconnected output should re-
main off.
To disconnect all levels in the distribution matrix:
Hold down <Take> and press <Cancel>. No output keys need
to be pressed.
To check if the outputs were disconnected:
While in status mode press any output key. All input LED’s
should remain off; if they do not, the disconnection did not
work.

Disconnecting a Signal Using QuickDis
You can also disconnect a specified input or output on all lev-
els; this is called QuickDis. QuickDis is designed for
distribution matrices that switch component signals using
multiple I/O boards and multiple levels. If the signals need to
be disconnected quickly, all at once, QuickDis is the answer.
For example, if a distribution matrix is used to control com-
