Ventilation Recommendation
Excessive heat decreases the optimal lifetime of the power amplifier.
An Over Temp LED indicator on the front panel of the amplifier lights
red when the recommended operating temperature has been exceeded.
The NetPA Ultra amplifiers need to be arranged in a rack environment, so
that the environment around the amplifier does not reach or exceed +122
°F (+50 °C). No more than four amplifiers should be stacked without a
ventilation opening between the groups.
The NetPA U 2002 SB can also be arranged above or below a non-NetPA
Ultra device, but in any case, the environment should never reach or exceed
+122 °F (+50 °C).
