Patchbays can be changed by inserting jumpers or turning individual modules.
With the help of our ULTRAPATCH PRO PX2000, an easy-to-use 24-Patchbay offering phone jacks through-
out, you can easily understand the four different modes. With the ULTRAPATCH PRO you can select
between the four different operating modes simply by setting a switch on the upper panel (example:
module 17):
4.3.2 Parallel
Fig. 4.1: Patchbay mode parallel
In this mode, all terminals of one module are interconnected. This configuration doesnt make sense at first
glance but is used to split up and send one audio signal (e.g. Aux Send) to several destinations (e.g. effects
devices).
4.3.3 Half-normalled

In this configuration, the contacts of the two jacks on the rear are interconnected. When you insert a plug into
the upper front jack, the signal routed through the rear path is not interrupted. Only when the lower front jack
is used will the rear panel route be split up, so that the two upper and the two lower phone jacks are connected
to one another. This configuration is called input break and is used mainly for insert paths. So you can
easily patch the signal from a mixing console channel at the Patchbay without interrupting the signal flow in
the channel.
4.3.4 Normalled
Fig. 4.3: Patchbay mode normalled
Here, and in contrast to the half-normalled setup, the signal route of the rear phone jacks is interrupted
when you insert a plug both into the upper and lower front jacks.
