The I

Q–P.I.P.-MEM

monitor and control capabilities to your Crown PIP™ (programmable input processor) and PIP2-compatible amplifiers.

An IQ2-series component, the IQ– P.I.P.-MEM support Crown’s UCODE protocol and requires an IQ System with an IQ2-compatible IQ Interface (such as IQ-INT V2.00). UCODE (universal code) enables users and third parties to develop custom software objects to control and monitor IQ2-compatible components like the IQ–P.I.P.-MEM.

The IQ–P.I.P.-MEM connects the amplifier to the Crown Bus of an IQ System so the amplifier can be controlled and monitored. It is powered by the amplifier and includes a microprocesser with a memory backup feature that enables the amplifier to resume operation with all of its IQ settings in tact after a power outage.

This manual will help you successfully install your unit. We strongly recommend that you read all the instructions, warnings and cautions contained within. Also for your protection, please send in the warranty registration card today and save the bill of sale since it is your official

proof of purchase.

Reference Manual

IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems

C. Reset Switch

A multifunction reset switch is provided to restore the IQ–P.I.P.-MEM to a prior state. It can be depressed with a straightened paper clip through the small hole in the PIP panel. Press the reset switch for less than 2 seconds and all settings, except the amplifier model scale factors, will be reset with “user default” parameters and the DSPI will flash once. (If no “user default” settings have been stored, the unit will be reset to the “factory default” settings described next.) Press the reset switch for more than 2 seconds and the same settings will be reset with “factory default” parameters and the DSPI will flash twice. After the unit has been reset to the factory default settings, it will behave like a standard P.I.P.FX until it is reprogrammed by an IQ System or it is toggled to the “user default” settings.

D. AUX Connector

A 3-pin male mini XLR connector is provided to control auxiliary equipment. When the AUX feature is turned on, +15 VDC is provided across pin 1 (gnd) and pin 3 (+). A nominal current of 10 mA is available. The AUX connector also includes a high-impedance input that can sense logic signals.

E. DSPI

The DSPI is a Data Signal Presence Indicator which flashes whenever a valid IQ command has been received. The indicator can also be forced to stay on to aid rapid troubleshooting of the Crown Bus wiring.

F. Crown Bus Input Connector

A lockable 5-pin female DIN connector is provided for input connection to the Crown Bus. A mating Switchcraft 502 series connector can be ordered from Crown (part C 7776-5). Pin 1 is negative (–), pin 2 is positive (+), and pin 3 is ground (gnd). Pins 4 and 5 are not used.

G. Crown Bus Output Connector

A lockable 4-pin female DIN connector is used for output connection to the Crown Bus. A mating Switchcraft 502 series connector can be ordered from Crown (part C 7777-3). Pin 1 is negative (–) and pin 2 is positive (+). Pins 3 and 4 are not used.

H. Input Switches (S1, S2)

An 8-section DIP switch is used to configure each input. These switches are located on the bottom circuit board. S1 configures the input of Channel 1 and S2 configures the input of Channel 2. The switches activate a microphone preamp and enable phantom power. The preamp can be turned off (0 dB gain) or set to either 20 or 40 dB of gain. See Section 4.1.

I. PIP Edge Connector

The gold-plated edge connector of the top IQ circuit board inserts into the PIP connector inside the back of the amplifier. Use care when installing a PIP module to be certain that the edge connector is properly inserted into the amplifier’s PIP connector.

Reference Manual

Page 11

IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems

J. Amplifier Output Pad Jumpers (JP4, JP5)

These jumpers enable the circuitry that pads the output signal feeding the IQ–P.I.P.-MEM so it can be properly scaled. Factory default setting for these jumpers is the “OUT” position as marked on the digital circuit board. Switch to the “IN” position whenever the unit is installed into a PIP-style amplifier.

K. PIP2 SIP Sockets (RN1, RN2)

These eight-pin SIP (single in-line package) resistors are provided for full PIP2 compatibility. IQ– P.I.P.-MEM-PIP2 modules (required for PIP2-compatible amplifiers) should come with the SIP networks already installed. The SIP networks are not required and should be absent on standard IQ– P.I.P.-MEM modules.

L. IQ Circuit Board (Top)

The top circuit board contains the

IQ communication circuitry, including the IQ address switch (SW1), amplifier output pad jumpers (JP4, JP5), PIP2 SIP resistors (RN1, RN2) and the PIP edge connector.

M. Audio Circuit Board (Bottom)

The bottom circuit board contains the audio analog circuitry, including the input switches (S1, S2).

N. IQ Address Switch (SW1)

An 8-section DIP switch is used to set the IQ address of the unit (see Section 4.1). This switch is located on the top circuit board. Each IQ component on a Crown Bus is given a unique IQ address so it can be independently controlled and monitored. Two or more IQ components of the same type should NEVER have the same address on the same Crown Bus loop.
