foundations with their weight and visceral 

impact. Mid and high frequencies will bloom

true to your system’s inherent virtues.

Installation:

Unpacking

Before unpacking your unit, inspect the carton 

for any obvious severe damage to the box and 

internal protective materials. If internal damage 

is likely, contact the carrier who delivered the 

unit before proceeding with unpacking. If, after 

unpacking, shipping damage is evident, contact 

the carrier. Save all shipping and packing 

materials.  You may need them if you should 

ever have to return the unit to the factory for 

servicing.

The box should contain the IT-REFERENCE 

20 unit, detachable AC cord, rack mount kit, 

owner’s manual, and warranty registration 

card.  If anything is missing, please contact 

Furman Customer Service.  Fill out and return 

your warranty registration card.  Registration 

is recommended because it can be used 

to establish whether the unit is within the 

warranty period should your original ownership 

documents be lost, and it assists us in 

informing you about upgrades or other vital 

information.   

Safety Information - Warnings

qualifi ed service personnel when:

  operate normally, or exhibits a marked  

  change in performance.

  The IT-Reference 20 has been dropped, or  

  the enclosure damaged.

ground be present for proper operation. Any 

attempt to operate the IT-Reference 20 

without a safety ground is considered improper
