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 bot-
tom 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 inter-
rupt the circuit. (Can be used to moni-
tor the normalling circuit)
Other versions of normalling are Half Normalled Top Row, Full
Normalled, Parallel and Isolated.
Introduction
Patch Panels are central switching gears between audio equip-
ments. 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.

Patch Panels are available in a varety of jack types, wir-
ing and grounding possibilities. Common versions accommodat-
ing 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.
