36、 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 a
37、nd even from various countries in order to achieve desired objectives. 3 General For safety considerations, reference is required to IEC Publication 65: Safety Requirements for Mains Operated Electronic and Related Apparatus for Household and Similar General Use. NOTE 1The preferred electrical match
38、ing values for the interconnection of sound system components are given in IECPublication268-15: Sound System Equipment Part15:Preferred Matching Values for the Interconnection of Sound System Components. NOTE 2Connectors for the interconnection of sound system components for other applications are
39、dealt with in IECPublication268-11: Part 11: Application of Circular Connectors for the Interconnection of Sound System Components. NOTE 3For applications other than those given in this standard, reference is required to IEC Publications 130-8 andIECPublication130-9. At present not all connectors re
40、ferred to in this standard are included in these publications. 4 Application and contact designation For low-level 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 low-level concentric connectors,
41、 the contact arrangement and application shall be as given in Table III and the contact designation shall be as given in Table IV.
