IMPORTANT NOTICE

 

ADCOM PROTECTION PLAN 

(U.S.A ONLY) 

ADCOM  offers  the  enclosed  valuable  Limited  Warranty.  Please  read  the  details  on  the 
Warranty card carefully to understand the extent of the protection offered by the Warranty, 
its reasonable limitations, and what you should do in order to obtain its benefits. Please 
register your warranty online at www.adcom.com or www.adcom-usa.com 
 
Be sure to verify that the serial number printed on the rear panel matches the serial number 
on the outer carton. If any number is altered or missing, you should notify us immediately 
in order to insure that you have received a genuine ADCOM product which has not been 
opened, mishandled or tampered with in any way. 

 

UNPACKING

 

Before your GFA-585se left our plant, it was carefully inspected for physical imperfections 
and tested for all electrical performance parameters as a routine part of ADCOM's systematic 
Quality  Control.  This,  along  with  full  operational  and  mechanical  testing,  should  insure  a 
product flawless in both appearance and performance. After you have unpacked the GFA-
585se,  inspect  it  for  physical  damage.  Save  the  shipping  carton  and  all  internal  packing 
materials,  as  they  are  intended  to  reduce  to  a  minimum  the  possibility  of  transportation 
damage, should the amplifier ever need to be shipped again. In the unlikely event damage 
has occurred, notify your dealer immediately and request the name of the carrier so that a 
written claim to cover shipping damages can be initiated. 
THE  RIGHT  TO  A  CLAIM  AGAINST  A  PUBLIC  CARRIER  CAN  BE  FORFEITED  IF  THE 
CARRIER IS NOT NOTIFIED PROMPTLY IN WRITING AND IF THE SHIPPING CARTON 
AND PACKING MATERIALS ARE NOT AVAILABLE FOR INSPECTION BY THE CARRIER. 
SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS BEEN SETTLED.   
 

INSTALLING THE GFA-585se

 

The  GFA-585se  is  equipped  with  large  heatsinks  to  dissipate  the  heat  generated  by  the 
output power transistors. Although during normal home operation the heatsinks will become 
just warm to the touch, there are instances during high-level playback into low impedance 
speakers which will cause the heatsinks to become much warmer than normal. 

Therefore, 

adequate  air  circulation  MUST  be  made  available  to  ensure  proper  heat  dissipation 
from the heatsinks.

 You will ensure the amplifier's long-term, trouble-free operation if you
