IQ P.I.P.–SMT
Recommendations: Attach
a small label to the back of
the
P.I.P. to identify whether it
has been set for microphone
or line-level input signals.
And keep the output levels
low if you are uncertain of the
preamplifier settings. Re-
member, Crown is not liable
for damage due to overpow-
ering other components.
3. Set the jumpers JP4 and
JP5.
If the IQ–P.I.P.–SMT is
being installed into a PIP2-
compatible or Macro-Tech
5000VZ amplifier, move both
jumper JP4 and JP5 on the IQ
circuit board to the “OUT” po-
sition (Figures 2.1 and 4.8).
Set both JP4 and JP5 to the
“IN” position for all other am-
plifiers.
4.2 Prepare the Amplifier
4. Turn down the level con-
trols
(full counterclockwise)
and turn off the amplifier .
5. Disconnect the amplifier’s
power cord.
6. Remove the existing P.I.P. or
cover panel from the ampli-
fier back panel (two screws).
For
PIP2 amplifiers, this may
involve disconnecting the
P.I.P. from a PIP2 input
adapter (Figure 4.6). If a
PIP2
input adapter is already
present, do not remove the
ribbon cables from the
adapter. Otherwise you will
have to reconnect them in
Step 10.
7. Set the amplifier input sen-
sitivity to 0.775 V.
(See the
amplifier’s Reference
Manual.)
4.3 Install the IQ–P.I.P.–SMT
into the Amplifier
8. Carefully ground yourself to
the chassis of the amplifier
before installing the
IQ–P.I.P.–
SMT. It is a good idea to
maintain ground contact be-
tween yourself and the ampli-
fier while inserting the
module into the
P.I.P. card
rails (standard P.I.P.-compat-
ible amplifiers) or the PIP2
connector ( PIP2-compatible
amplifiers).
9. Install the IQ–P.I.P.–SMT
into the amplifier:
Standard P.I.P. Amplifiers:
Align the edges of the
IQ–
P.I.P.–SMT in the P.I.P. card
rails and firmly push the unit
in until it is seated against the
mounting bracket (see Figure
4.5).

PIP2 Amplifiers: Connect the
PIP2 input adapter to the two
input cables of the amplifier
(Figure 4.6). Notice that the
PIP2 input adapter should be
positioned with the
P.I.P.
edge connector on top facing
away from the amplifier. The
20 pin cable (A) is connected
first then the 18 pin cable (B)
is connected. Both ribbon
