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.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems 3 Features With an IQ–P.I.P.-MEM module a Crown amplifier can be monitored and controlled by an IQ System. This typically involves a host computer (usually a PC), attached to the IQ System via an IQ2-compatible IQ interface, running IQ software. Please contact your Crown representative or Crown’s Technical Support Group if you are unfamiliar with IQ software. 3.1 Amplifier Information (PIP2 amplifiers only.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems The output signal of some amplifiers must be padded before the IQ–P.I.P.-MEM can scale them. This is accomplished by setting jumpers JP4 and JP5 on the IQ circuit board to the “IN” position. Only PIP2-compatible amplifiers do not require these pads. Set jumpers JP4 and JP5 to the “OUT” position for them (see Figure 4.8). The output signals of all amplifiers must be scaled in order to “calibrate” the 0 dB level. (See Section 4.5.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems 3.14 Memory Backup A memory backup feature is provided which can be disabled, if desired. The factory default setting is “enabled.” When enabled, it stores all run-time parameters that can be controlled by the IQ software into nonvolatile memory (EEPROM) at approximately one second intervals. When disabled, all run-time parameters are returned to the factory defaults whenever the unit loses power.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems Fig. 4.1 IQ Address Switch (SW1) Location 4 Installation Before beginning, please carefully note: CAUTION: STATIC ELECTRICITY MAY DAMAGE THE IQ–P.I.P.-MEM MODULE. Use caution when handling the unit. Carefully ground yourself BEFORE touching the IQ– P.I.P.-MEM module. For added safety, touch the outer metal collar of either Crown Bus connector (Figure 2.1). This should safely discharge any static electricity through the ground plane of the module.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems the same Crown Bus Loop can have the same address. Suppose, for example, the IQ System has two Crown Bus loops and this IQ–P.I.P.MEM is installed into loop 1 and given address 77. No other IQ–P.I.P.-MEM can have the same address in loop 1. However, an IQ– P.I.P.-MEM in loop 2 can have the same address. Different IQ components in the same Crown Bus loop can have the same address. For example, both an SMX-6 mixer and an IQ–P.I.P.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems Fig. 4.3 Input Switch (S1, S2) Location Fig. 4.4 Input Switch (S1, S2) Settings IMPORTANT: Two switch segments (S1, S2) are required for each setting. Be careful to use both segments or improper operation will result. Switch S1 configures the input to Channel 1 and switch S2 configures the input to Channel 2. CAUTION: The IQ–P.I.P.MEM input preamplifiers should only be used with microphone or low-level signals.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems being installed into a PIP2compatible amplifier, move both jumper JP4 and JP5 on the IQ circuit board to the “OUT” position (Figures 2.1 and 4.8).

The Crown Bus is a serial communication loop designed to transmit IQ commands and data. As implemented in the IQ–P.I.P.-MEM, it is a 20 milliamp current loop operating at a BAUD rate of 38.4 K.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems (shielded or unshielded). If fiber optic wiring is required contact the Crown Technical Support Group (see page 4). Here are some guidelines for twisted-pair wiring: • Use shielded twisted-pair wire at least 26 AWG in size when interference is a problem. The wire should be of good quality and should have low capacitance—30 picofarads/foot or less is good. (West Penn 452 or an equivalent wire works well.

IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems The IQ components in a Crown Bus loop are wired sequentially. The loop begins and ends with the IQ interface. The output of one IQ component “loops” to the input of the next and so on as shown in Figure 4.14. Figure 4.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems 4.7 A Closer Look at Audio Signal Wiring Balanced 3-pin female XLR connectors are provided for audio input connection. The audio cables should be wired in one of the two manners shown in Figure 4.15: We strongly recommend that balanced wiring be used if possible. Some important guidelines follow: • Always use shielded wire. The higher the density of the shield (the outer conductor), the better. Spiral wrapped shield is not recommended.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems 4.8 Using the AUX Connector 4.8.1 AUX Output The IQ System offers tremendous flexibility and the auxiliary feature connector provides a means of tapping into it. It can be used to turn something on/off, send a signal to another component and receive a signal from another component. (See Figure 4.16 for internal circuit diagram.) When the auxiliary feature is turned on by the IQ System software +15 VDC is supplied across pins 1 (ground) and 3 (+).
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems Note: A Crown part number is provided in the given illustration for a suitable solid-state relay (C 73087). Contact your local Crown representative or the Crown factory Parts Department (219-294-8200) to order. By monitoring the operating condition of amplifiers with the IQ System software, the need for additional cooling will be apparent. The same software could then be used to turn on the appropriate AUX connector.
IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems tally controlled attenuator. Following the attenuator, the signals pass through a final output buffer stage, which also can invert the polarity of the signal when required. The audio signal is then fed through the PIP edge card connector and into the amplifier. 5.2 Amplifier Monitoring: “Monitor Inputs” The IQ–P.I.P.-MEM can monitor the status of the amplifier using a number of “monitor inputs.” There are two types of signals—audio and status.

IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems 7 IQ Address Tables This section contains lookup tables for every valid IQ address. The valid addresses are 1 to 250. Remember that address “0” (zero) will put the IQ– P.I.P.-MEM into a stand-alone mode where it is invisible to the IQ System and acts like a “dumb” balanced audio input. Do not use an address number higher than 250! Addresses above 250 are reserved for special system use.
