Operation Manual

Crown amplifiers are quality units that rarely require ser-
vicing. Before returning your unit for servicing, please 
contact Crown Technical Support to verify the need for 
servicing.

This unit has very sophisticated circuitry which should 
only be serviced by a fully trained technician. This is one 
reason why each unit bears the following label:

CAUTION: To prevent electric shock, do not 
remove covers. No user serviceable parts 
inside. Refer servicing to a qualified technician.

Complete the Crown Audio Factory Service Information 
form, in the back of this manual, when returning a Crown 
product to the factory or authorized service center. The 
form must be included with your product inside the box 
or in a packing slip envelope securely attached to the 
outside of the shipping carton. Do not send this form 
separately.

Warranty is only valid within the country in which the 
product is purchased.

5.1 Worldwide Service

Service may be obtained from an authorized service cen-
ter. (Contact your local Crown/Amcron representative or 
our office for a list of authorized service centers.) To 
obtain service, simply present the bill of sale as proof of 
purchase along with the defective unit to an authorized 
service center. They will handle the necessary paperwork 
and repair.

Remember to transport your unit in the original factory 
pack. 

5.2 US and Canada Service

Service may be obtained in one of two ways: from an 
authorized service center or from the factory. You may 
choose either. It is important that you have your copy of 
the bill of sale as your proof of purchase.

5.2.1 Service at a US or Canada Service 
Center

This method usually saves the most time and effort. Sim-
ply present your bill of sale along with the defective unit 
to an authorized service center to obtain service. They 
will handle the necessary paperwork and repair. Remem-

ber to transport the unit in the original factory pack. A list 
of authorized service centers in your area can be obtained 
from Crown Factory Service, or online from 
http://www.crownaudio.com/support/servcent.htm.

5.2.2 Factory Service

Crown accepts no responsibility for non-serviceable 
product that is sent to us for factory repair. It is the

viceable prior to sending it to the factory. Serviceable

For warranty service, we will pay for ground shipping 
both ways in the United States. Contact Crown Customer 
Service to obtain prepaid shipping labels prior to send-
ing the unit. Or, if you prefer, you may prepay the cost of 
shipping, and Crown will reimburse you. Send copies of 
the shipping receipts to Crown to receive reimbursement. 

Your repaired unit will be returned via UPS ground.
