U.420 Limited Warranty

Please keep your sales receipt in a safe place.

A.

 LOUD Technologies Inc. warrants all materials, 

workmanship and proper operation of this product for a period 

of 

one year

 from the original date of purchase. You may 

purchase an additional 24-month Extended Warranty (for a 

total of 36 months of coverage). Visit our website and follow 

the “Product Registration” links for details (www.mackie.com). 

If any defects are found in the materials or workmanship or 

if the product fails to function properly during the applicable 

warranty period, LOUD Technologies, at its option, will repair 

or replace the product. 

This  warranty applies only to 

equipment sold and delivered within the U.S. and Canada 

by LOUD Technologies Inc. or its authorized dealers.
B.

 For faster processing, register online at www.mackie.com, 

or you may fill out and mail in the product registration card 

included along with this manual.

C.

 Unauthorized service, repairs, or modification of Mackie 

products will void this warranty. To obtain repairs or replacement 

under warranty, you must have a copy of your sales receipt from 

the authorized Mackie dealer where you purchased the product. 

It is necessary to establish purchase date and determine whether 

your Mackie product is within the warranty period.  

D.

 To obtain warranty repair or replacement:

 1. 

Call Mackie Technical Support at 800/898-3211, 7 AM  

to 5 PM Monday through Friday (Pacific Time) to get 

authorization for repair or replacement. Alternately, go to 

the Mackie website, click “Support” (www.mackie.com/

support), and follow the instructions for reporting a warranty 

issue and submitting a request for an advance replacement. 

 

2. Advance Replacement:

 Mackie will ship a replacement 

unit to you along with an invoice for the suggested 

retail price of the replacement unit. You must return the 

defective unit immediately to cancel the invoice. If you do 

not return the defective unit within 30 days, you must pay 

the full amount stated in the invoice to satisfy your debt.

 

3. Repair:

 When you call Mackie Technical Support, 

explain the problem and obtain a Service Request 

Number. Have your Mackie product’s serial number 

ready. 

You must have a Service Request 

Number before you can obtain factory-

authorized service.

 

 

•  Pack the product in its original shipping carton. Also 

include a note explaining exactly how to duplicate the 

problem, a copy of the sales receipt with price and date 

showing, your daytime phone number and return street 

address (no P.O. boxes or route numbers, please!), and 

the Service Request Number. If we cannot duplicate the 

problem or establish the starting date of your Limited 

Warranty, we may, at our option, charge for service time 

and parts.

 

• Ship the product in its original shipping carton, 

freight prepaid

 to the authorized service center. Write 

the Service Request Number in 

BIG PRINT

 on top of 

the box. The address of your closest authorized service 

center will be given to you by Technical Support, or it 

may be obtained from our website. Once it’s repaired, 

the authorized service center will ship it back by ground 

shipping, pre-paid (if it qualified as a warranty repair). 

 

Note:

 Under the terms of the warranty, you must ship 

or drop-off the unit to an authorized service center. 

The return ground shipment is covered for those units 

deemed by us to be under warranty.

 

Note:

 You must have a sales receipt from an authorized 

Mackie dealer for your unit to be considered for 

warranty repair.

IMPORTANT:  Make  sure that the Service Request 

Number is plainly written on the shipping carton.  

No receipt, no warranty service.
E.

 LOUD Technologies reserves the right to inspect any 

products that may be the subject of any warranty claims before 

repair or replacement is carried out. LOUD Technologies may, 

at our option, require proof of the original date of purchase in 

the form of a dated copy of the original dealer’s invoice or sales 

receipt. Final determination of warranty coverage lies solely 

with LOUD Technologies. 

F.

 Any products returned to one of the LOUD Technologies 

factory-authorized service centers, and deemed eligible 

for repair or replacement under the terms of this warranty 

will be repaired or replaced. LOUD Technologies and its 

authorized service centers may use refurbished parts for repair 

or replacement of any product. Products returned to LOUD 

Technologies that do not meet the terms of this Warranty 

will not be repaired unless payment is received for labor, 

materials, return freight, and insurance. Products repaired 

under warranty will be returned freight prepaid by LOUD 

Technologies to any location within the boundaries of the USA 

or Canada.

G.

 LOUD Technologies warrants all repairs performed 

for 90 days or for the remainder of the warranty period. 

This warranty does not extend to damage resulting from 

improper installation, misuse, neglect or abuse, or to exterior 

appearance. This warranty is recognized only if the inspection 

seals and serial number on the unit have not been defaced or 

removed.

H.

 LOUD Technologies assumes no responsibility for the 

timeliness of repairs performed by an authorized service 

center.

I.

 This warranty is extended to the original purchaser. This 

warranty may be transferred to anyone who may subsequently 

purchase this product within the applicable warranty period 

for a nominal fee. A copy of the original sales receipt is 

required to obtain warranty repairs or replacement.

J.

 This is your sole warranty. LOUD Technologies does not 

authorize any third party, including any dealer or sales 

representative, to assume any liability on behalf of LOUD 

Technologies or to make any warranty for LOUD Technologies 

Inc.

K.

 THE WARRANTY GIVEN ON THIS PAGE IS THE SOLE 

WARRANTY GIVEN BY LOUD TECHNOLOGIES INC. 

AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS 

AND IMPLIED, INCLUDING THE WARRANTIES OF
