ART Pro Audio TPatch - Eight Point Balanced Patch Bay - Manual (Page 7)

USING A PATCH BAY:
Although the ART TPatch, like all patch bays, is
conceptually a simple device, there is a lot in the
terminology and usage conventions that can potentially
cause confusion. Each vertical grouping of two jacks on
the front of the unit and the corresponding two jacks and
switch on the rear of the unit comprise a module and
provides one channel of linked input/output audio
connections. For example, the jacks labeled 1 and 5 on
the front panel and the jacks labeled 1 and 5 on the rear
panel, along with the associated switch, are one
module. All four modules are identical and each may be
individually configured for Half Normal or Normal
operation. Read on to find out what this means.
