In example 3, the StudioPatch Series (6425) is connected to a four-channel compressor, and a four-channel
microphone preamp. Since these two outboard devices use a total of eight channels, one DB25 to 1/4-inch
TRS breakout cable can be used for all of the inputs, and one can be used for all of the outputs. The
patchbay’s channels 1 through 8 will then have the compressor and mic-pre outputs on the top row, and
the compressor and mic-pre inputs on bottom row. In this case, the normalling screw would most likely be
set for non-normalled ("N" position) to prevent the possibility of unwanted feedback loops.
Now, the patchbay has 48 patchpoints, or 24 channels left that can be used. Keep in mind, that you can
create any type of configuration that you wish…this is just one example. The jacks do not all have to be
normalled the same way in groups. It all depends on your particular configuration.
