In this mode, when all jacks of the module are inserted, the
audio signals A and B will go separately from front to rear. For
example, you may use this mode to connect mixer outputs to
compressor inputs or compressor outputs to tape inputs.

Here, the contacts of jacks A & B on the rear are interconnected. The configuration is the same as in mode 4. However,
in contrast to mode 4, this mode is usually deployed for equipment
in a fixed installation. For example, most recording studios have
the mixers outputs connected to the recorders inputs most of
the time. It is very convenient to have the signal path through the
patchbay in this manner, with the permanent connections made
at the rear. This also allows you to intercept, divert or replace
the signal easily at the front of the patchbay in a number of ways
by inserting a plug into one of the front jacks (A or B).
Here, the contacts of jacks A & B on the rear are interconnected. When you insert a plug into the upper front jack (A),
the signal routed through the rear path is not interrupted and the
audio source of front A is parallel to the rear jacks (A & B).
Thus, two power amplifiers may, for example, share one audio
source.
After removing the mains hum from the system, make up your
cable looms from the patchbays outwards, and use cable ties,
flexible sheaths, multicores, etc. to keep the back of your racks
orderly.

2. LOOMING PROBLEMS

3. CAUTIONS
Avoid routing digital signals near a patchbay because the pulse
signal used for the transmission of such signals causes heavy
interference in analog signals. Additionally, normal patchbays
change the impedance of the digital cable route, which
causes interference in the digital path. Use the BEHRINGER
ULTRAMATCH PRO SRC2496 specifically designed for this and
other digital signal-related functions.
3. CAUTIONS
ULTRAPATCH PX1000
Microphone inputs operate at a level several orders of magnitude
lower than line levels (+4 dBu or -10 dBV). Therefore, they
should never be routed via a patchbay. In any case, patching in
a field with +48 V DC (phantom power) is to be avoided at all
costs. It is best to plug mics directly into the mixing console or via
special XLR type wall boxes connected to the mic inputs of the
console using good quality balanced multicore cables.

4. LABELLING
With so many patch points in use at any one time, you will
probably never be able to keep track of them without labelling.
Your BEHRINGER ULTRAPATCH PX1000 features white labels
above the upper jacks and white labels below the lower jacks
for the purpose of labelling. When labelling, it is advisable not to
use permanent markers as you may want to re-label, if you
decide to re-configure your patchbay signal routing again.
5. PATCHBAY ORGANIZATION
Attached is an example configuration that shows how you
can use your patchbay. This is only an example to illustrate the
use of your PX1000. Depending on your application, you may
need several PX1000s. It should be noted that patchbays should
be placed one below the other in such a way that the patch
cords dont hang carelessly over the patchbays.
