Adcom GFA-555 PRO Owner's Manual page 3

SECTION 1
WHAT TO DO WHEN XOU OPEN THE BOX
Before each GFA-555 left the factory, it was carefully inspected for physical imperfections as a routine part
of ADCQM's systematic quality control. This along with full electrical testing, should insure a product flawless in both
appearance and performance. After you have unpacked the amplifier, inspect it for physical damage. Save the shipping
carton and all packing materials as they are essential to reduce to a minimum the possibility of transportation damage
should the product ever need to be shipped again. In the unlikely event that damage has occurred, notify your dealer
immediately and request the name of the carrier so that a written claim to cover shipping damage can be initiated.
THE RIGHT TO ANY CLAIM AGAINST A PUBLIC CARRIER CAN BE FORFEITED IF THE
CARRIER IS NOT NOTIFIED PROMPTLY AND IF THE SHIPPING CARTON AND PACKING MATERIAL
ARE NOT AVAILABLE FOR INSPECTION. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS
BEEN SETTLED.
SECTION 2
WHERE TO PUT IT (AND WHERE NOT TO!)
The GFA-555 utilizes large external heat sinks to dissipate heat from the power transistors. The top and
bottom panels of the amplifier have slots to allow air to circulate inside the amplifier. Adequate air circulation must
be available to ensure cool operation of the amplifier. Therefore, the GFA-555 should not be completely enclosed
with other heat producing components, and adequate space around the amplifier should be maintained. We recommend
at least 3 inches on the top and 1 inch on the sides and rear for air circulation. If the GFA-555 is going to be mounted
in an enclosed cabinet, it is recommended that the back of the cabinet have vents to allow air to circulate around the
amplifier. With these considerations in mind, the GFA-555 should perform quite happilv in anv reasonable environment.
Of course, such normal considerations as protection from excessive dust and moisture should alwavs be observed.
The ADCOM GFA-555 power amplifier has been carefully designed with high quality components so that long term
undiminished performance may be expected from the amp when it is operated in accordance with the instructions
provided.
