Unpacking and Placement

Unpacking

Unpack your Proceed

®

 AMP 2 or AMP 3 power amplifier and 

keep all packing

materials for future transport

. Shipment of the amplifier without the original

packing material is 

not 

recommended. Locate and remove the heavy gauge AC

power cord, which is tucked into a cardboard slot within the box.

Placement

Your Proceed AMP 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 AMP. We suggest leaving at least
three inches of free space behind your AMP to allow all cables
sufficient room to bend without crimping or undue strain.

Ventilation

Be sure to allow 2 to 3 inches of clearance above your AMP to allow heat dissi-
pation through air circulation. The vents on both the bottom and the top of the
AMP 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 AMP is too
hot to touch when “idle,” it needs better ventilation. If so, consider drilling holes
in the supporting shelf under the AMP 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 AMP
on the floor near your loudspeakers, be sure to place it on a firm surface. (A
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 AMP.
