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.
