There is one Master patch unit per console, and it carries all the main inputs
and outputs from the Master Audio Module. As with the Channel patch unit it
has two rows of 48 jacks and is connected to the Audio Tower via one 90-pin
Elco snake. All the inputs and outputs to the external studio equipment are
connected to the unit through 38-pin Elco connectors.
As with the Channel unit, the upper jacks are console outputs and lower jacks
are console inputs; signal flow in the patchbay is from top to bottom. All the
upper jacks are half-normalled to the lower jacks.
The 90-way Elco at the far left is the Tower interface. The remaining 5 Elco 38
connectors are the user interface. The pinout diagrams can be found in the
Service Manual.
Note that the Master patchbay labels have blank areas for user label-
ling. These are for the user-definable inputs and outputs to the Master
audio section. Following is a diagram that shows the user inputs and
outputs for a standard Master patch unit. The Channel patch unit also
has user-definable ins and outs.
