B Portable Rack Mounting
1.
3.
Rules for mounting in portable racks (road cases) аге basi-
cally the same as for when less than five amplifiers are
mounted in a single rack. However, when mounting a
power amplifier in a case made for housing only one ampli-
fier, mount a blank panel (ventilated) below the amplifier
and make ventilation holes (with a numerical aperture of
0.4 or greater) in the left and right sides of the top panel of
the case (corresponding to the amplifier heat sinks) as
shown in the illustration at right.
See the dimensions diagram for the exact location of the
heat sinks.
* If a blank panel (ventilated) cannot be mounted in the
case, make ventilation holes in the bottom of the case
corresponding to the holes in the top, as shown in the
illustration at right, and attach legs with a height of at
least 20 mm to the bottom to make sure that air can
circulate underneath and through the case.
Positioning the housed amplifier
Place the case so that the ventilation airflow paths are not
blocked.
