example, let's say we needed to send a signal other
than the mixer's output signal to the recorder's
Channel 1 input. (A keyboard, for example.) All you
would have to do is plug that keyboard's cable into
the corresponding
bottom-front jack of the bay. The
signal from the mixer's Channel 1 Output would be
interrupted, and the keyboard's signal would be
substituted. (Fig 2 d., below.)
Figure 2 d. Arrows indicate direction of signal flow. Here,
we have interrupted the "usually-connected" mixer-to-
recorder signal path just by connecting a keyboard's signal
to the bottom-front jack (which breaks the connection
between top and bottom in the back).

"Full-Normalled"
(Switch to Left Position)
A "Full-normalled" bay is one which allows you to
break the connection between the
rear top and
bottom jacks by plugging a cable into either the
bottom-front jack or the top-front jack.
This configuration is the most versatile of the various
types of bays because you can either "steal" source
signals or substitute different load signals simply by
plugging into either the top or bottom jacks.
Notice, however that the scenario in Figure 2b. on
Page 2 is not possible with a full-normalled bay
configuration. With a full-normalled bay, a signal
could never be sent to top front
and bottom rear at
the same time as it can in a half-normalled bay.

Front
With nothing
plugged into the
front jacks, signal
continues
uninterrupted from
top to bottom in
the rear.

When a cable is
plugged into the
top-front jack, the
signal between top
and bottom in the
rear is interrupted.
When a cable is
plugged into the
bottom-front jack,
the signal between
top and bottom in
the rear is
interrupted.
Figure 3 (a., b., c., d.) Arrows indicate direction of signal
flow. The full-normalled bay acts just like a half-normalled
bay except for scenario "b." above. When a plug is
inserted into the top-front position of a full-normalled bay,
signal between top and bottom in the back is interrupted.
(Compare with half-normalled bay, Fig. 2b., Page 2.)
With cables plugged into
both top and bottom jacks
in the front, the signal
between top and bottom
in the rear is interrupted.
