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 product, for a period of three (3) years from the date of purchase by the original purchaser (the “warranty period”) that the new Crown product is free of defects in materials and workmanship. We further warrant the new Crown product regardless of the reason for failure, except as excluded in this 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. W e 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 or at the factory. We will remedy the defect and ship the product fr o m the service center or our factory within a reasonable time after receipt of the defective product at our authorized service center or our factory. All expenses in r emedying the defect, including surface shipping costs in the United States, will be borne by us. (You must bear the expense of shipping the product between any foreign country and the port of entry in the United States and all taxes, duties, and other customs fees for such foreign shipments.)

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, which, if needed, may be obtained from us free of charge. Corrective action will be taken within a reasonable time of the date of receipt of the defective product by us or our authorized service center. If the repairs made by us or our authorized service center are not satisfactory, notify us or our authorized service center immediately.

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 . INCIDENTINCIDENT

1.1 Unpacking

The unit is shipped in a protective

antistatic bag.

CAUTION: STATIC ELECTRICITY MAY DAMAGE THE UNIT. Use cau-

tion when handling the unit. Carefully ground yourself BEFORE touching the unit. For added safety, touch the outer metal collar of either Crown Bus connector. Avoid unnecessarily touching the components, edge connector or solder pads on the circuit

™

boards. Please unpack and inspect the unit

for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately . Only you, the consignee, may initiate a claim with the carrier for shipping damage. Crown will be happy to cooperate fully as needed. Save the shipping carton as evidence of damage for the shipper’s inspection.

Even if the unit arrived in perfect condition, as most do, save all packing materials. NEVER SHIP THE UNIT

WITHOUT THE F ACTOR Y P ACK.

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.

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.

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.
