Cooling Tips
If you allow spaces between pieces of equipment in your rack,
make sure you block the front with blank, solid (not perforated) pan-
els. This will allow the rack to act as a chimney with hot air exhaust-
ing at the top, not re-circulating between adjacent amplfiers.
2.7—Turn on all equipment ahead of the amplifier
such as
the mixer or preamplifier. Adjust their signal levels to their
optimum “signal to noise” settings as defined in their op-
erating manuals.
2.8—Plug the amplifier into the power receptacle, turn on
the amplifier and adjust its level controls to a desired
setting. Please be sure to follow the steps outlined in the
Operation section (page 29) if this is the first time the am-
plifier is being turned on.
2.9—Check to make sure adequate ventilation has been
provided. Even though this amplifier has some of the
most efficient heat sinks in the marketplace, it must be
able to breathe. So make sure that the front vents are
never blocked and that the exhaust fan (out the back) is
not blocked or covered by cables.
An amplifier running at high sound pressure levels into
low-impedance loads, will typically put out lots of hot air,
so make sure it can go somewhere.
If you are running your equipment in dusty or dirty en-
vironments, it is advisable to pre-filter the air using in-
dustrial furnace filters. These filters can be taped or
fastened to the front of the equipment rack, ensuring a
clean air supply through a large surface area that will
require minimum maintenance.
