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-PIP-USP2 in the shortest time possible.
Less experienced installers or those wishing a full explanation of the installation
procedure are encouraged to go to Section 3 where the full installation procedure
is described.
Prepare the IQ-PIP-USP2:
1. Set the IQ address switch S1 (see Figures 2.1 and 3.1) on the IQ-PIP-USP2 to
an unused IQ address. (Tip: Record the IQ address on the small field labeled
“IQ ADDRESS” that is provided on the PIP panel.)
2. Set the Input/Output Scaling switch S3 (see Figures 2.1 and 3.2) for the desired
scaling.
Prepare the amplifier:
3. Turn down the level controls of the amplifier and turn off the amplifier.
4. Unplug the power cord of the amplifier from the AC mains.
5. Remove the existing PIP™ or cover panel from the amplifier back panel (two
screws).
Install the IQ-PIP-USP2 into the amplifier:
6. Carefully ground yourself to the chassis of the amplifier before installing the IQ-
PIP-USP2. 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.
7. Turn the PIP upside down so you can clearly see the two ribbon cable connec-
tors located on the underside of the board near the back corner (see Figure
2.1). 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
PIP module.
Important: Be careful when attaching the ribbon cable to the connector that
the cable is properly seated before applying pressure to the connector. Forc-
ing 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 result in damage to the PIP
When both cables are firmly attached, turn the IQ-PIP-USP2 back to an upright
position and insert into the PIP opening in the back of the amplifier. Take care
while inserting the PIP to make sure you do not crimp, pinch or stretch the
ribbon cables.
8. Tighten the two PIP mounting screws until it is secured to the amplifier back
panel, making sure the supplied star-washers penetrate the powder-coat fin-
ish of the PIP panel for good ground connection.
Install the wiring:
9. Connect the IQ-PIP-USP2 to the IQ System via the Crown Bus (see Section
3.4 if more information is needed).
10. Connect the audio signal wiring to the IQ-PIP-USP2 (see Section 3.4 if more
information is needed).
11. Connect the amplifier back to the AC mains.
