Consumer Interface
In the case of the consumer interface, the standards
call for an unbalanced circuit having a receiver im-
pedance of 75Ω ± 5%. The connector for the con-
sumer interface is an RCA phono plug (fixed
socket described in Table IV of IEC268-11). The
receiver circuit for the consumer interface is shown
in Figure 23.
