FOREWORD
The formal decisions or agreements of the I E C on technical matters, prepared by Technical Committees on which all the
1)
ational consensus
National Committees having a special interest therein are represented, express, as nearly as possible, an inte rn
of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
In order to promote international unification, the I E C expresses the wish that all National Committees should adopt the text of
3)
the I E C recommendation for their national rules in so far as national conditions will permit. Any divergence between the I E C
recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.
The I E C has not laid down any procedure concerning marking as an indication of approval and has no responsibility when an
4)
item of equipment is declared to comply with one of its recommendations.

SOUND SYSTEM EQUIPMENT
Part 12: Application of connectors for broadcast
and similar use
Scope
1.
This standard applies to circular and concentric connectors to be used for the interconnection of
sound system components for broadcast and similar use and gives the applications and also the
contact arrangement and contact designation for these connectors.
2. Object
In sound systems for broadcast and similar use it is often necessary to connect pieces of
equipment from different manufacturers and even from various countries in order to achieve
desired objectives.
General
3.
3.1 The connectors shall comply with the electrical and mechanical requirements given in I E C
Publications:
– 130-8: Connectors for Frequencies below 3 MHz, Part 8: Concentric Connectors for Audio
Circuits in Radio Receivers;
– 130-9: Part 9: Circular Connectors for Radio and Associated Sound Equipment.
3.2 For safety considerations, reference is required to I E C Publication 65: Safety Requirements for
Mains Operated Electronic and Related Apparatus for Household and Similar General Use.
Notes 1. – The preferred electrical matching values for the interconnection of sound system components are given in I E C
Publication 268-15: Sound System Equipment, Part 15: Preferred Matching Values for the Interconnection of
Sound System Components.
2. – Connectors for the interconnection of sound system components for other applications are dealt with in I E C
Publication 268-11: Pa rt 11: Application of Circular Connectors for the Interconnection of Sound System
Components.
For applications other than those given in this standard, reference is required to I E C Publications 130-8 and
3. –
130-9. At present not all connectors referred to in this standard are included in these publications.
4. Application and contact designation
For circular connectors, the contact arrangement and application shall be as given in Table I and
the contact designation shall be as given in Table II. For concentric connectors the contact
arrangement and application shall be as given in Table III and the contact designation shall be as
given in Table IV.
