Main input channels are most often used for the monitor mix, a Compressor in the channel insert would raise
the signal level in soft passages and induce feedback in the monitor system.
4.3 Patchbay
A Patchbay allows to patch the audio signals of most components in your studio from a central point and send
them to other units, which makes your entire cabling better structured and is indispensable for professional
work. If you want to use your studio as effectively as possible then it is preferable to use a complete Patchbay
wiring scheme, but even less sophisticated patchbay solutions will benefit smaller studio configurations.
4.3.1 Patchbay configuration
The majority of commercially available Patchbays include two rows with 24 phone jacks each in a 19" 1 HU
rack panel. On the rear, either a corresponding number of phone jacks or contacts for soldering signal leads
can be found. Each group of four of these phone jacks forms one module. The configuration of some
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
throughout, 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
Fig. 4.2: Patchbay mode 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.
