PatchBay

SSL's PatchBay is a 24 x 8 automated router unit, which may be controlled directly
from the J Series Computer. Each crosspoint comprises a balanced relay closure to
provide a true bi-directional selection. PatchBays can be equally used with analogue
audio, AES/EBU digital audio or machine control lines. If PatchBays are currently not
fitted in your system, contact your local SSL office or distributor for more details.
Select MACHINES followed by PatchBay. The screen will look similar to that shown
opposite, and comprises three main areas. Note that this will show information for the
last PatchBay on the system accessed via this display.

Input/Output Names

To the left of the crosspoint display you will see a column of 'row' boxes. These show
the current assignments for the 8 inputs/outputs of that PatchBay.
Normally, the basic settings for this display will be established during the system
commissioning period. The following instructions are provided should you wish to
change the function of a particular PatchBay.
The legends in the 'row' boxes are selected for individual PatchBays by stabbing on
the upper box (Free in the example opposite). This produces a pop-up from which
alternative functions may be selected for the current PatchBay. If Free is selected on
this pop-up, custom legends for the inputs/outputs may be entered by stabbing on
individual row boxes. Enter the name on the QWERTY keyboard pop-up and press
END.
If Names (in the lower half of the screen) is selected, the current assignments for the 24
inputs/outputs will be seen above the crosspoint display. New entries may be made,
or existing entries changed, by stabbing on one of the boxes. Enter the name on the
QWERTY keyboard pop-up and press END.
Do not attempt to change these input/output entries unless the installation has been
altered.

The Crosspoint Display

Most of the screen is taken up with the crosspoint display, above and to the left of
which you will see the name, eg. VIDEO, INPUTS or OUTPUTS etc., given to the
PatchBay you are currently viewing.
Connections may be simply made by stabbing on the appropriate square in the grid.
Each input-to-output assignment is unique; successful connections will show with a
yellow square. If the PatchBay unit is local to your operating position, you will hear a
faint mechanical click as each assignment is made and the corresponding red LEDs
will light on PatchBay's front panel.
