Quick Install Procedure
This procedure is provided for those who would like to install the PIP card in the shortest time
possible and are already familiar with Harman Pro System Architect and HiQnet. A more complete
installation procedure is outlined in the installation section.
Prepare the amplifi er:
1. Turn down the level controls of the amplifi er and turn off the amplifi er.
2. Unplug the power cord from the AC mains.
3. Remove the existing PIP or cover from the amplifi er back panel (two screws).
4. On the PIP-USP4-CN, make sure that the input sensitivity switches located inside the
amplifi er are in the 26dB mode (middle) position for both, channel 1 and 2.
Install the PIP module into the amplifi er:
5. Carefully ground yourself to the chassis of the amplifi er before installing the PIP card. It is a
good idea to maintain ground contact between yourself and the amplifi er while inserting the
module into the amplifi er in the next step.
6. Position the PIP module so the ribbon cable connectors located along the back edge on the
underside of the module can be clearly seen. Attach the ribbon cables from the amplifi er to
the ribbon-cable connectors. For PIP-Lite, the 20 pin cable (A) should go to the connector
closest to the corner (J2A) and the 18 pin cable (B) should go to the other connector. For
PIP-USP4-CN, make sure to install the supplied ferrite core to the 18 pin cable (B) before
connecting. The 20 pin cable (A) should go to the connector further inside and away from the
corner (AJ9), and the 18 pin cable should connect to the one closest to the corner (BJ5).
Important: Be careful when attaching the ribbon cable to the connector. Applying pressure
to an improperly seated connector could cause the keying tabs, which ensure proper pin
alignment, to break. Connecting the ribbon cables with improper pin alignment will likely
result in damage to the PIP.
7. With both cables fi rmly attached, turn the PIP back to an upright position. Verify that the
cables run untwisted between the amplifi er and the PIP. Insert the PIP into the amplifi er while
taking care not to crimp, pinch or stretch the ribbon cables.
8. Tighten the two PIP mounting screws until it is secured to the amplifi er back panel, making
sure the supplied star-washers contact the PIP panel for a good ground connection.
9. Make sure the amplifi er is left in Dual mode – Bridging is done via software (USP4-CN only)
Install the wiring:
10. Connect the PIP to the Ethernet network used for control. Each PIP must connect to its own
port on a 100 Megabit Ethernet Switch with a standard straight CAT5 network cable. A 10
Megabit connection will work with the PIP-Lite but is not recommended for systems with a
high number of components. A 10 Megabit connection will not work with the PIP-USP4-CN.
11. Connect the amplifi er back to the AC mains and reset the back panel input attenuators to
the proper levels. For the USP4-CN the input attenuators should be set to wide open, no
attentuation for all the features to function properly.
