4.1.2 Other Requirements

Short Circuit Protection at Output Stage

The amplifier should be protected so that no functional failure

occurs when it is operated with a short across its output stage

for 2 minutes. The amplifier should recover after removing the

short condition.

Over Voltage Protection

In case a regulation loop in the unit gets defectives, the output

voltage shall not exceed more than 30% of the nominal value.

Thermal Protection

There should not be any breakdown or activation of any

protection circuit during the entire thermal profile test. Refers to

the Therma

l Profile test stated in Reliability Test Plan for

Multimedia Powered Speaker System.

Environmental Conditions

The unit should work between +5 C till 45 C under ambient

temperature.

The unit should not get damaged within the temperature range

of +5

C till 60 C ambient temperature.
