Reference Manual
Figure 4.5 shows how the output of the IQ–P.I.P.–SLM is
wired to an IQ component with a similar connector.
Wiring the output of a similar IQ component back to the
input of the IQ–P.I.P.–SLM is simply the reverse.
4.8 A Closer Look at Audio Signal Wiring
Balanced 3-pin removable Eurostyle barrier block con-
nectors are provided for audio input connection. The
audio cables should be wired in one of the following
manners (see Figure 4.9):

2-wire line cord
(or battery power)
Note: If two or more channels with
the same input ground reference
are driven from the same
floating source, connect
only one shield to the
source chassis.

The next two figures show how to connect the IQ–P.I.P.–
SLM to IQ components with different connectors. Figure
4.6 shows how to connect the
IQ–P.I.P.–SLM to an IQ
component with a DIN input connector.

Figure 4.7 shows how to connect an IQ component with
a DIN output connector to the
IQ–P.I.P.–SLM.
The IQ components in each Crown Bus loop are wired
sequentially. The loop begins and ends with the IQ
interface. The output of one IQ component “loops” to
the input of the next and so on as shown in Figure 4.8.
