Unpacking and Placement
Unpacking Unpack your Proceed ® HPA 2 Power Amplifier and keep all packing materials
for future transport . Shipment of the amplifier without the original packing
material is not recommended, as it is heavy enough to make improvised packag-
ing impractical. Locate and remove all accessory items from the cartons, and store
the cartons for possible future use.
Carefully inspect the product for shipping damage. If you discover any, see your
Proceed dealer immediately.
Placement Your Proceed amplifier may be placed either near the preamplifier/control center
or near the loudspeakers. It may be placed on a shelf or in a cabinet where it is
convenient to operate.
Note that adequate clearance for the AC cord and connecting
cables must be left behind your amplifier. We suggest leaving at
least three inches of free space behind your amplifier to allow all
cables sufficient room to bend without crimping or undue strain.
Ventilation Be sure to allow at least 2 to 3 inches of clearance above your amplifier to allow
heat dissipation through air circulation. The vents on both the bottom and the top
of the amplifier must be kept free from any obstruction which would reduce the
flow of air through the unit. The best rule of thumb is this: if the top of your am-
plifier is too hot to touch when “idle,” it needs better ventilation. If so, consider
drilling holes in the supporting shelf under the amplifier to promote flow-through
ventilation, or use fans to increase air circulation.
Open equipment racks are generally best for power amplifiers, as they allow
ample ventilation. If your amplifier must be located inside a cabinet which re-
stricts airflow, consider using some fans to increase ventilation.
Avoid placement on soft surfaces such as carpeting. If you prefer to have the am-
plifier on the floor near your loudspeakers, be sure to place it on a firm surface.
(A thick piece of tempered glass under the amplifier is aesthetically unobtrusive
while providing firm support and allowing the required ventilation.)
Mechanical drawings are included in this manual to facilitate special installations
and custom cabinet work (see “Dimensions” at the end of this manual).
PRECAUTION For your protection, review “Important Safety Instructions”
before you install your amplifier.
