IQ Address Switch (SW1) A 3-pin, Eurostyle, removable barrier-block connector is provided to control auxiliary equipment. The AUX output delivers 15 VDC at 15 mA maximum output when switched on and may be controlled via software or may be programmed to switch when a fail condition is present on any channel.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems 3 Features The IQ–P.I.P.-SLM is a powerful companion for any Crown PIP2 amplifier, with a range of features that allow an attached amplifier to be monitored, controlled and tested via the IQ System. The various functions of the IQ–P.I.P.-SLM can be categorized into two areas: auto-control features and signal-and-load-monitoring features. The auto-control features provided by the IQ–P.I.P.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems 3.10 Data Indicator A Data LED is provided on the front panel. It flashes whenever commands addressed to the IQ–P.I.P.-SLM are received. It can be forced to stay on by IQ software to assist with troubleshooting of an IQ System. 3.11 Aux Port A 3-pin Eurostyle removable barrier-block connector is provided to control auxiliary equipment.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems If “user default” settings have been previously established through the IQ software, these settings will be enabled when the reset switch is pressed and immediately released. The “Data” indicator (located on the front panel of the IQ–P.I.P.-SLM) will also flash once to verify this change.. When the reset switch is pressed and held (at least two seconds), the component will switch to the factorydefault settings.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems Note: While the frequency ranges of the tests for each channel will be restricted to those set by individual start/stop parameters, the sweep itself will begin at the lower of the two Start frequencies and end at the higher of the two Stop frequencies. The sweep becomes active/audible only over the frequency range defined for each channel.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems Please note that when Sync Mode is selected, the main audio inputs are used and no digital signal is produced by the IQ–P.I.P.–SLM's internal DDS, since it is assumed that an appropriate alternate DDS (from an IQ–SLM-8, for example) is being properly utilized. When Sync Mode is not selected, however, the IQ–P.I.P.–SLM uses its own DDS and the main audio inputs are disabled. from 1% to 100%.

IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems card and a PIP2 input adapter. If so, remove both the P.I.P. card and the PIP2 adapter by detaching the ribbon cables from the PIP2 adapter. The P.I.P. card and PIP2 adapter may then be inserted into another P.I.P.-compatible amplifier, or may be stored for future use. Be sure to store both the P.I.P. and adapter in antistatic packaging.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems 9. Connect the audio signal wiring to the IQ– P.I.P.–SLM. Two 3-pin Eurostyle barrier block input wiring connectors, one for each channel, are provided on the IQ–P.I.P.–SLM. See Section 4.8 for full instructions. 10. Reconnect amplifier to the AC receptacle. 4.5 Prepare the Audio System Since the IQ–P.I.P.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems commands and data. As implemented in the IQ–P.I.P.– SLM, it is a 20 milliamp current loop operating at a BAUD rate of 38.4 K. The loop must be unbroken. If the system includes an IQ–INT II interface, it can accept eight different Crown Bus loops or zones. Dividing the sound system into different zones, each with its own Crown Bus loop, can have several advantages.

IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems We strongly recommend that balanced wiring be used if possible. Some important guidelines follow: The internal AUX circuit is shown below in Figure 4.10: +15 V • Always use shielded wire. The higher the density of the shield (the outer conductor), the better. Spiral wrapped shield is not recommended. • When using unbalanced lines, keep the cables as short as possible. Avoid lengths greater than 10 feet (3 meters).
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems channels have failed a test. By reversing the logic, the AUX output will not send a pass signal when the unit is turned off or has no power. 4.9.3 Controlling External Devices (AUX Output) There are many other possible uses for the AUX output. For example, it can be used to turn on auxiliary cooling fans. To do this the +15 VDC AUX output would be used to close a relay. The relay would then turn the fans on or off.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems 5 Technical Information The purpose of the IQ–P.I.P.–SLM is to provide remote control and monitoring of a PIP2-compatible amplifier. In addition, the IQ–P.I.P.–SLM provides Load Monitoring functions which allow storage of amplifier voltage (frequency response) and load impedance curves. See Sections 1 and 2 for a detailed description of features and facilities. Figure 5.

IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring for IQ Systems 6 Specifications General Internal Controls: An 8-segment DIP switch is used to set the IQ address (decimal range: 1–250). A Reset switch, accessible with a straightened paper clip through the P.I.P. panel, resets all settings (except the amplifier initialization data) to the “user defaults” if it is pressed for less than 2 seconds or the factory defaults if it is pressed for more than 2 seconds.
IQ–P.I.P.–SLM Programmable Input Processor with Load Monitoring 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.–SLM 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.
