1 Welcome
Crown ScreenArray® PIP modules
are custom two-channel crossover
networks with equalization specifically designed for use with JBL
ScreenArray cinema speaker systems installed in cinemas, studio
production and post-production
environments. The PIP-4622 is designed for use with model 4622
Screen Array system, the PIP-3632
is designed for use with model 3632
Screen Array system, and the PIP4632 is designed for use with model
4632 Screen Array system.
The ScreenArray PIP modules install into the back of Crown PIP2-

compatible amplifiers*, saving
rack space and simplifying system
wiring.
The HD15 connector on Screen
Array PIPs is designed for quick and
easy interface with popular cinema
monitor products such as the USL
CM680.
* You must have a PIP2-compatible
amplifier to use the ScreenArray
PIP modules. To determine if your
amplifier is PIP2-compatible, look
for the
logo on the back of
the amplifier. The ScreenArray PIP
modules are NOT compatible with
older Crown PIP amplifiers.

2 Installation
2.1 Prepare the Amplifier
1. Turn down the level controls (full
counterclockwise) and turn off the
amplifier.
2. Disconnect the amplifier’s power
cord.
3. Remove the existing
amplifier back panel (two screws).
This may involve disconnecting the
PIP from a PIP2 input adapter. If a
PIP2 input adapter is already
present, remove the ribbon cables
from the adapter.
2.2 Install the PIP into the
Amplifier
1. Carefully ground yourself to the
chassis of the amplifier before
installing the PIP module. It is a good
idea to maintain ground contact
between yourself and the amplifier
while inserting the module into the
amplifier.
2. Install the PIP module into the
amplifier: Turn the PIP module over
so that you can clearly see the two
ribbon-cable connectors located on
the underside of the circuit board
(see Figure 2.1). Connect the two
input ribbon cables of the amplifier.
The 20-pin cable (A) should be
connected first, then the 18-pin
cable (B) should be connected.
Both ribbon cables should run
smoothly from the amplifier to the PIP
card (see Figure 2.1).

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 result in damage to the
PIP.
When both cables are firmly
attached, turn the PIP module back
to an upright position and insert into
the
PIP opening in the back of the
amplifier. Take care while inserting
PIP to make sure you do not
the
crimp, pinch or stretch the ribbon
cables.
3. Tighten the two PIP mounting
screws
PIP is secured to the
until the
amplifier back panel. Be sure to use
the supplied star-washers for
good ground connection.

2.3 Choice of Input
Connector and Pad
The HD15 connector on Screen Array
PIPs provides input signal and amplifier
output monitoring with popular cinema
monitor products such as the USL
CM680.
Input and output sensitivity for the USL
CM680 and similar products is 3Vrms.
This relatively high sensitivity coupled
with the gain found in ScreenArray PIPs
limits headroom. For example, the PIP3632 has approximately 11dB of gain at
20 kHz. If the input is 3Vrms at 20 kHz,
there is only 2dB of headroom. In the
vast majority of systems this reduced
headroom will not be a problem.
However, if more headroom is needed,
consider using the defeatable 6.6dB
pad in the PIP ScreenArray
crossovers. When activated, this pad
will attenuate an incoming 3Vrms signal
to 1.4Vrms- providing approximately
8.6dB for headroom. Jumper Z1 is in the
0dB attenuation position by default
(Figure 2.2).
As seen in Figure 2.3, the HD15
connector and the removable terminal
are in parallel. Care should be taken to
not drive both inputs at once. However,
it is acceptable to use the removable
terminal connector to "jumper" the input
signal to another amplifier if necessary.
When a PIP ScreenArray module is
used in conjunction with an USL CM680
or similar product, a single standard
VGA cable can be used to provide input
audio and output voltage-confidence
monitor to and from the amplifier.
A standard VGA cable is a male-tomale cable with High Density 15 pin
connectors on each end. VGA cables
are readily available at most electronics
and computer stores, as they are
utilized on almost every computer
monitor currently in production. (VGA
cables are not included with the PIPs.)
