Quick Install Procedure
This procedure is provided for those who are already familiar with Crown’s IQ System
and who would like to install the IQ–P.I.P.–SLM in the shortest time possible. Less
experienced installers or those wishing a full explanation of the installation procedure
are encouraged to go to Section 4 where the full installation procedure is described.
Prepare the IQ–P.I.P.–SLM:
1. Set the IQ address switch SW1 (see Figures 4.1 and 4.2) on the IQ–P.I.P.–SLM to an
unused IQ address. (Tip: Record the IQ address on the small blank label that is pro-
vided on the
P.I.P. panel.)
Prepare the amplifier:
2. Turn down the level controls of the amplifier and turn off the amplifier.
3. Unplug the power cord of the amplifier from the AC mains.
4. Remove the existing P.I.P. or cover panel from the amplifier back panel (two screws).
Install the IQ–P.I.P.–SLM into the amplifier:
5. Carefully ground yourself to the chassis of the amplifier before installing the IQ–P.I.P.–
SLM. It is a good idea to maintain ground contact between yourself and the amplifier
while inserting the module into the amplifier in the next step.
6. Turn the P.I.P. upside down so you can clearly see the two ribbon cable connectors
located on the underside of the top board near the back corner (see Figure 4.3). Attach
the ribbon cables from your amp to the ribbon-cable connectors. The 20-pin cable
should be connected first, then the 18-pin cable should be connected. Both ribbon
cables should run untwisted from the amplifier to the
P.I.P. card.
Important: Important: Important: Important: Important: Be careful when attaching the ribbon cable to the connector that the cable
is properly seated before applying pressure to the connector. Forcing the cable onto
the connector could cause the keying tabs, which ensure proper pin alignment, to
break. Connecting the ribbon cables with improper pin alignments may well result in
catastrophic damage to the P.I.P. component.
When both cables are firmly attached, turn the IQ–P.I.P.–SLM back to an upright posi-
tion and insert into the P.I.P. opening in the back of the amplifier. Take care while insert-
ing the P.I.P. to make sure you do not crimp, pinch or stretch the ribbon cables.
7. Tighten the two P.I.P. mounting screws until it is secured to the amplifier back panel.
Install the wiring:
8. Connect the IQ–P.I.P.–SLM to the IQ System via the Crown Bus (see Section 4.6 if more
information is needed).
9. Connect the audio signal wiring to the IQ–P.I.P.–SLM (see Section 4.7 if more informa-
tion is needed).
10. Connect the amplifier back to the AC receptacle.
