The Crown Audio Division of Crown International, Inc., 1718 West Mishawaka Road, Elkhart, Indiana 46517-4095 U.S.A. warrants to you, the ORIGINAL PURCHASER and ANY SUBSEQUENT OWNER of each NEW Crown purchase by the original purchaser (the “warranty period”) that the new Crown product is free of defects in materials and workmanship, and we further warrant the new Crown product regardless of the reason for failure, except as excluded in this Crown Warranty.

Note: If your unit bears the name “Amcron,” please substitute it for the

name “Crown” in this warranty.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

This Crown Warranty is in effect only for failure of a new Crown product which occurred within the Warranty Period. It does not cover any product which has been damaged because of any intentional misuse, accident, negligence, or loss which is covered under any of your insurance contracts. This Crown Warranty also does not extend to the new Crown product if the serial number has been defaced, altered, or removed.

We will remedy any defect, regardless of the reason for failure (except as excluded), by repair, replacement, or refund. We may not elect refund unless you agree, or unless we are unable to provide replacement, and repair is not practical or cannot be timely made. If a refund is elected, then you must make the defective or malfunctioning product available to us free and clear of all liens or other encumbrances. The refund will be equal to the actual purchase price, not including interest, insurance, closing costs, and other finance charges less a reasonable depreciation on the product from the date of original purchase. Warranty work can only be performed at our authorized service centers. We will remedy the defect and ship the product from the service center within a reasonable time after receipt of the defective product at our authorized service center.

You must notify us of your need for warranty service not later than ninety (90) days after expiration of the warranty period. All components must be shipped in a factory pack. Corrective action will be taken within a reasonable time of the date of receipt of the defective product by our authorized service center. If the repairs made by our authorized service center are not satisfactory, notify our authorized service center immediately.

DISCLAIMER OF CONSEQUENTIAL AND INCIDENTAL DAMAGES

YOU ARE NOT ENTITLED TO RECOVER FROM US ANY INCIDENTAL DAMAGES RESULTING FROM ANY DEFECT IN THE NEW CROWN PRODUCT. THIS INCLUDES ANY DAMAGE TO ANOTHER PRODUCT OR PRODUCTS RESULTING FROM SUCH A DEFECT.

No person has the authority to enlarge, amend, or modify this Crown Warranty. This Crown Warranty is not extended by the length of time which you are deprived of the use of the new Crown product. Repairs and replacement parts provided under the terms of this Crown Warranty shall carry only the unexpired portion of this Crown Warranty.

We reserve the right to change the design of any product from time to time without notice and with no obligation to make corresponding changes in products previously manufactured.

No action to enforce this Crown Warranty shall be commenced later than ninety (90) days after expiration of the warranty period.

Quick Install Procedure

This procedure is provided for those who are already familiar with Crown’s and who would like to install the experienced installers or those wishing a full explanation of the installation procedure are encouraged to go to Section 4 where the full installation procedure is described.

Prepare the IQ–P.I.P.–SLM:

1. Set the IQ address switch SW1 (see Figures 4.1 and 4.2) on the unused IQ address. (Tip: Record the IQ address on the small blank label that is provided on the

Prepare the amplifier:

2. Turn down the level controls of the amplifier and turn off the amplifier.

3. Unplug the power cord of the amplifier from the AC mains.

4. Remove the existing

Install the IQ–P.I.P.–SLM into the amplifier:

5. Carefully ground yourself to the chassis of the amplifier before installing the

. 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.

6. Turn the P.I.P. upside down so you can clearly see the two ribbon cable connectors located on the underside of the top board near the back corner (see Figure 4.3). Attach the ribbon cables from your amp to the ribbon-cable connectors. The 20-pin cable should be connected first, then the 18-pin cable should be connected. Both ribbon cables should run untwisted from the amplifier to the

C. AUX Input/Output Connector

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.* The AUX connector also includes a high-impedance (10 K ohm) input that can sense logic signals and can be programmed to trigger a test or report fault conditions when a logic high is present. In this case the sweep is leading-edge triggered and may be aborted by sending a second leading-edge trigger. (See Section 4.7 for more information.)

E. Data LED

The Data LED 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/Output Connector

A 4-pin, Eurostyle, removable barrier-block connector is provided for both input and output connection to the Crown Bus.

*The AUX output uses inverse logic when it is configured to report a fail condition. Normally high, it switches low when any channel fails a test. In this way it can also indicate a power loss.

G. IQ Address Switch (SW1)

An 8-section DIP switch is used to set the IQ address of the unit (see Section 4.1 and (L) below). A valid IQ address is any number from 1 to 250. Do not use a number higher than 250 since they are reserved for special use. This switch is located on the top (IQ) circuit board. Each IQ component on a Crown Bus is given a unique IQ address so it can be independently controlled and monitored. T wo or mor e IQ components of the same type should NEVER have the same address on the same Crown Bus loop.
