Unpacking and Placement
Unpacking Unpack your Proceed ® BPA 2 or BPA 3 power amplifier and keep all packing
materials for future transport . Shipment of the amplifier without the origi-
nal 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 BPA 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 BPA. We suggest leaving at least
three inches of free space behind your BPA 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 BPA to allow heat dissipa-
tion through air circulation. The vents on both the bottom and the top of the BPA
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 BPA is too hot
to touch when “idle,” it needs better ventilation. If so, consider drilling holes in
the supporting shelf under the BPA 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 BPA
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).
For your protection, review “Important Safety Instructions”
before you install your BPA.
