IQ-PIP-Lite
Quick Install Procedure
This procedure is provided for those who would like to install the IQ-PIP-Lite in the shortest time
possible and are already familiar with Crown’s IQ System and TCP/IQ. 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 amplifier:
1. Turn down the level controls of the amplifier and turn off the amplifier.
2. Unplug the power cord from the AC mains.
3. Remove the existing PIP or cover from the amplifier back panel (two screws).
Install the IQ-PIP-Lite into the amplifier:
4. Carefully ground yourself to the chassis of the amplifier before installing the IQ-PIP-Lite. 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.
5. Turn the PIP upside down so the ribbon cable connectors located along the back edge on the
underside of the module can be clearly seen (See Figure 3.1). Attach the ribbon cables from
the amplifier to the ribbon-cable connectors. The 20 pin cable (A) should connect to the connector closest to the corner and the 18 pin cable (B) should connect to the other connector.
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.
6. With both cables firmly attached, turn the IQ-PIP-Lite back to an upright position. Verify that
the cables run untwisted between the amplifier and the PIP. Insert the PIP into the amplifier
while taking care not to crimp, pinch or stretch the ribbon cables.
7. 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 finish of the PIP panel for a good
ground connection.
Install the wiring:
8. Connect the IQ-PIP-Lite to the Ethernet network used for TCP/IQ control. Each PIP must connect to its own port on a 100 Megabit Ethernet Switch with a standard straight CAT 5 network
cable. (See Section 3.4 if more information is needed.) A 10 Megabit connection will work but
is not recommended for systems with a high number of components.
9. Connect the audio signal wiring to the IQ-PIP-Lite. (See Section 5.1 for more information.)
10. Connect the amplifier back to the AC mains and reset the back panel input attenuators to the
proper levels.

1 Welcome
The IQ-PIP-Lite is a PIP™ (Programmable Input Processor) input module for PIP2™
compatible amplifiers.* It connects the amplifier to a 100 Mb Ethernet network allowing it
to be remotely controlled and monitored via IQ
Figure 1.1 IQ-PIP-Lite Module
The IQ-PIP-Lite is a TCP/IQ series component. This means it connects to an IQ System®
via 100 Mb Ethernet. This provides faster IQ communications than the previous current
loop, IQ bus, connectivity method. With TCP/IQ, a large (or small) system can be interconnected using standard off-the-shelf 100 Mb Ethernet components (Switches, NICs, and
cables). The IQ-PIP-Lite can also be connected to the same network used to pass CobraNet
1
audio .
The audio path in the IQ-PIP-Lite is processed totally in the analog domain without the
inherent noise induced by analog-to-digital conversions. While DSP-type functions cannot
be supported with this type of architecture, the standard SmartAmp™ features are. These
features include input compressors, multimode output limiters, error reporting and load
monitoring.
1.1 Unpacking
The unit is shipped in a protective antistatic bag. CAUTION: STATIC ELECTRICITY
MAY DAMAGE THE UNIT. Use caution when handling the unit. Carefully ground your-
self BEFORE touching the unit. Avoided unnecessary touching the components or solder
pads on the circuit board. It is best to handle the unit by its front panel only.

Please unpack and inspect the unit for damage that may have occurred during transit. If
damage is found, notify the transportation company immediately. Only the consignee may
initiate a claim with the carrier for shipping damage. Crown will be happy to cooperate fully
as needed. Save the shipping carton as evidence of damage for the shipper's inspection.
Even if the unit arrived in perfect condition, as most do, save all the packing materials.
NEVER SHIP THE UNIT WITHOUT THE FACTORY PACK.
*A PIP2™-compatible amplifier is necessary to use the IQ-PIP-Lite. To determine if the amplifier is PIP2
compatible, look for the logo on the back of the amplifier. The IQ-PIP-Lite is NOT compatible
with older Crown PIP amplifiers unless a USP2 adapter is first installed in the amplifier. See Section 8
for more detail on the USP2 adapter.

Before beginning, please carefully note:
CAUTION: STATIC ELECTRICITY MAY DAMAGE THE UNIT. Use caution when handling
the unit. Carefully ground yourself BEFORE touching the unit. Avoided unnecessary touching
the components or solder pads on the circuit board. It is best to handle the unit by its front
panel only.
3.1 Prepare the IQ-PIP-Lite
The IQ-PIP-Lite comes ready to install in the amplifier. This unit does not require setting the
“IQ address” as the older current loop, Crown bus, units did. Each IQ-PIP-Lite (as well as all
TCP/IQ components) come preprogrammed with a unique network (MAC) address. The IQ
address is then set (automatically or manually) via the IQ control software. (Also a TCP/IP network address will be set automatically.)
3.2 Prepare the Amplifier
Turn down the amplifier level controls (full counterclockwise) and turn off the
amplifier.
Disconnect the amplifier's power cord.
Remove the existing PIP module from the amplifier back panel (two screws). This may involve
disconnecting the PIP module from a PIP2 input adapter. If a PIP2 input adapter is present,
remove ribbon cables from the adapter.

3.4 Install the Wiring
1. Using a straight CAT 5 cable, connect the network connector to a 100 Mb port on an Ethernet switch that is used to form the TCP/IQ control network . For more detail see section 5.2,
TCP/IQ Network Basics. If the PIP module is not to be connected to a TCP/IQ control network, it can be temporarily connected to a computer’s Ethernet port with a twisted cable (TX
and RX pairs switched) to set up the PIP module for desired operation.
2. Connect the audio input wiring. The IQ-PIP-Lite module is equipped with removable barrier block connectors for each channel’s input. See Section 5.1 for more detail on audio
wiring.
3. Connect the AUX wiring if used. See Section 6.1 for more information.
4. Reconnect the amplifier's power cord.
5. Adjust the attenuator levels for optimum system gain on both the amplifier and on the IQPIP-Lite’s control panel (with IQ control software version 5.2 or higher).

4 Operation
With an IQ-PIP-Lite module, a Crown PIP2 amplifier can be monitored and controlled from
a remote location through the use of an IQ system. The PIP module features SmartAmp
capabilities that enable the amplifier to function automatically. For example, the IQ-PIP-Lite
can automatically turn off the high voltage supplies of the amplifier when no input signal is
present. This can lower electrical usage and provide long-term cost savings. The IQ-PIPLite can also automatically limit the audio signal, and detect and report various problems.
In addition, the Load Supervision feature can verify the status of the loads in real time.
The IQ-PIP-Lite module uses Crown's TCP/IQ protocol allowing it to be controlled over an
Ethernet network composed of standard, off-the-shelf 100Mb Ethernet components. Connection to the control computer is made through its standard network adapter. This protocol
still allows the IQ software greater flexibility with custom control pages and third-party controller support (AMX and Crestron) than the older IQ2 protocol.
The following sections describe the IQ PIP features and operation. Most features are controlled and configured using IQ for Windows software version 5.2 or higher. Please contact
a Crown representative or Crown’s Technical Support Group if you are unfamiliar with IQ
software. Figure 4.1 shows the system block diagram.
