IMPORTANT :
The power amplifier, during regular operation, needs a suitable cooling that can be done by
natural or forced ventilation.
Device installation must allow holes that permit a regular air flow. Air scoops are on the
front panel, air exit is from the rear panel.
In case of more amplifiers mounted on a single rack, air exchange could be poor; it’s
advisable, in this case, to provide forced ventilation to the rack too. It’s advisable that the
ventilation take place with the air aspiration from the bottom and the air emission from the
top of the rack.
