4.  You cannot let anybody who isn’t: (A) the AudioControl factory; (B) some-

body authorized in writing by AudioControl to service the BLX-1K.  If any-
one other than (A) or (B) messes with the BLX-1K, that voids your warranty.

5.  The warranty is also void if the serial number is altered or removed, or if 

the BLX-1K has been used improperly.  Now that sounds like a big loop-
hole, but here is all we mean by it. 
Unwarranted abuse is: (A) physical damage (don’t use the BLX-1K as a 
hammer!); (B) improper connections (480 volts into the power jack can fry 
the poor thing); (C) unreasonable use cases (like hot rodding your oven to 
pump out low frequency heat waves).  This is the best home audio prod-
uct we know how to build, but if you mount it to the to the inside of a dish 
washer, something will go wrong. 

6.  The warranty is five years from the date of purchase. 

Assuming you conform to 1 through 6, and it really isn’t all that hard to do, we 
get the option of fixing your old unit or replacing it with a new one.

The Warranty

People are scared of warranties.  Lots of fine print, months of waiting around.  
Well fear no more, this warranty is designed to make you rave about us to your 
friends.  It’s a warranty that looks out for you and helps you resist the temp-
tation to have your friend, “...who’s good with electronics”, try to repair your 
AudioControl product.  So go ahead, read this warranty, then take a few days 
to enjoy the BLX-1K before sending in the warranty card and comments. 
“Conditional” doesn’t mean anything ominous.  The Federal Trade Commission 
tells all manufacturers to use the term to indicate that certain conditions have 
to be met before they’ll honor the warranty.  If you meet all of the conditions, 
we will warrant all materials and workmanship on the BLX-1K for one year 
from the date you bought it (five years if it is installed by an authorized United 
States AudioControl dealer). We will fix or replace it, at our option, during that 
time.
Here are the conditional conditions:

1.  You have to fill out the product registration over at our website 

www.

audiocontrol.com

 and send it to us within 15 days after purchasing the 

BLX-1K.

2.  You must keep your sales receipt for proof of purchase showing when and 

from whom the unit was bought.  We’re not the only ones who require 
this, so it’s a good habit to be in with any major purchase.

3.  The BLX-1K must have originally been purchased from an authorized 

AudioControl dealer.  You do not have to be the original owner, but you do 
need a copy of the original sales slip.
