The next two figures show how to
connect the
IQ–P.I.P.–SMT
to other IQ
components with different connec-
tors. Figure 4.10 shows how the
Crown Bus output of the
IQ–P.I.P.–
SMT
should be connected to an IQ
component with a screw terminal
plug. Figure 4.11 shows how the
Crown Bus input of the
IQ–P.I.P.–SMT
should be connected to an IQ com-
ponent with a screw terminal plug.
The IQ components in a Crown Bus
loop are wired sequentially. The loop
begins and ends with the IQ inter-
face. The output of one IQ compo-
nent “loops” to the input of the next
and so on as shown in Figure 4.12.
4.7 A Closer Look at Audio
Signal Wiring
Balanced 3-pin female XLR connec-
tors are provided for audio input con-
nection. The audio cables should be
wired in one of the following manners:
We strongly recommend that bal-
anced wiring be used if possible.
Some important guidelines follow:
• Always use shielded wire.
The higher the density of the
shield (the outer conductor),
the better. Spiral wrapped
shield is not recommended.
• When using unbalanced
lines, keep the cables as
short as possible. Avoid
lengths greater than 10 feet
(3 meters).
• Do not run audio input cables
together with high-level wir-
ing such as loudspeaker
wires or AC cords. (This less-
ens the chance of hum or
noise being induced into the
input cables.)
