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
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
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
the top jack contact with the
corresponding bottom jack
contact. Inserting a plug in the
bottom jack will interrupt this
internal normalling connection,
while inserting a patch cord
into the top jack doesn‘t interrupt the circuit. (Can be used
to monitor the 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.
Configuration
The standard version of the NPPA Panel is delivered bottom row
half normalled for each jack pair by default. Further patch versions are available with fully loaded jack-pairs as:
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.
• Full Normalled
• Half Normalled
• Isolated
• Parallel
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.

Grounding
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
Wiring Terminations
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
For Pin assignment of ELCO / EDAC and D-SUB connectors please see drawings on www.neutrik.com
The spring loaded terminal blocks enable fast and easy wiring. 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
solid wires up to AWG 18 (0.75 mm
gas tight connections.
