Introduction
Patch Panels are central switching gears between
audio equipments. They are used to switch and
route analog and digital audio signals from and to
equipments in recording or broadcast studios, OB
vans, churches, theatres, stadiums, arenas, etc.
Neutrik
®
Patch Panels are available in a varety of jack
types, wiring and grounding possibilities.
Common versions accommodating Bantam TT, 1/4“
A-gauge and longframe B-gauge jacks on the front
rows are available.
The mechanical size is designed to fit into 1U 19“
standard racks. All Neutrik patch panels offer various
normalling possibilities between top and bottom
row.
All Neutrik
®
Patch Panels are able to handle digital
audio signals acc. AES3, 48kHz sampling rate.

Audio Normalling
Audio Normalling is usually used with audio patch
panels and is a wiring pattern in which a circuit path
is established from one piece of audio equipment to
another without the use of a patch cord. This pattern
is then considered to be the „normal“ circuit path that
is desired most of the time. If a patch cord is inserted,
the normal circuit path is interrupted and rerouted to a
different circuit path.
Normalled patch panels are most commonly found in
vertical jack pairs: the top jack is designated as the source
and the bottom jack is the destination.
Normalling example: HALF NORMALLED BOTTOM ROW
This is the most common
configuration,
very
often
called HALF NORMALLED. In
this configuration internal
normalling contacts connect
S
R
T
the top jack contact with the
corresponding bottom jack
contact. Inserting a plug in
the bottom jack will
S
interrupt this internal normalling
T
connection, while inserting a patch cord into the top jack
R
doesn‘t interrupt the circuit. (Can be used to monitor the
TN
normalling circuit)

Other versions of normalling are Half Normalled Top Row,
Full Normalled, Parallel and Isolated.

Design Criteria
All NPPA patch panels are fitted with high quality, long life
NJ3TTA gold plated double contact jacks (2x48), featuring best
contact integrity. The unit, robustly housed in a black coated
steel shell, is finished off with a built in cable bar and two large
channel identification strips for perfect management of the
system. The NPPA patch panels are an innovative and compact
patching system (just 1U high) for 19" rack mounting.
S e r i e s
Configuration
The standard version of the NPPA Panel is delivered bottom row
half normalled for each jack pair by default. Further patch ver-
sions are available with fully loaded jack-pairs as:
•
•
•
•
Full Normalled
Half Normalled
Isolated
Parallel
Half Normalled Top
S
R
T
For individual normalling single pre-configured jack-pairs
are offered.
NPPA-TT-IDC is equipped with jumper blocks for individual
switching configurations of each jack channel.
Note: Take care when handling digital signals. Do not use
parallel configuration and avoid other parallel paths when
using half normalled configurations. Parallel paths may lead
to mismatching.

The flexible grounding system provides the following versions:
•
Individual: Each channel is individually grounded by its corresponding cable shield (default configuration).
•
Group: Selected channel grounds are connected via the ground bus on the PCB using solder bridges and track cuts to form a
group that is connected to one common cable shield.
•
Central: All channel grounds (individual top and bottom row) are connected via the ground bus on the PCB using solder
bridges and wired with only one cable shield.
•
Chassis-Common: The same as central grounding but with the addition of the common ground bus (top and / or bottom
rows) connected to the patch panel chassis by means of jumpers
W i r i n g Te r m i n a t i o n s
TT patch panels offer different choices of wiring:
•
•
•
•
•
•
•
Spring loaded push terminals
56 pin Elco/Edac male connectors
90 pin Elco/Edac connectors
50 pin D-SUB connectors
25 pin D-SUB connectors
IDC-Krone terminals
Solder lugs
The spring loaded terminal blocks enable fast and easy wir-
ing. No soldering and screwing necessary. Simply insert the
stripped wire after pressing down the white key. Terminals
accommodate stranded wires up to AWG 20 (0.5 mm
2
) and
solid wires up to AWG 18 (0.75 mm
2
). Push terminals are
gas tight connections.
