This is Part 11 GB/T 12060 in.

Rules in this section in accordance with GB/T 1.1-2009 given draft.

This part of the international standard IEC 60268-11. 1987 "Sound system equipment - Part 11. Sound system equipment connectors for the interconnection should be

With "non-equivalent.

This Part replaces GB/T 14947-1994 "interconnection of sound system connected with the application."

Compared to major changes in this part of GB/T 14947-1994 as follows.

a) the full text of the editorial changes;

b) increase the foreword;

c) 4.3.2c) and the "Notes" in the "resistance" to "resistor";

d) increasing the "3.5mm mini concentric connectors (four contacts", "2.5mm subminiature concentric connector (3 contacts)";

e) "2.5mm subminiature connector concentric (4 contacts)" three types of concentric connector details, see 5.1;

f) adds three concentric connector types and applications in Table 8, see 5.2;

g) increase the allocation of three kinds of concentric connector contacts in Table 9, see 5.3.

This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
