Hello,
i am working for Public address system so when i comply the system with the specification i can't understand what they mean by this could you help me please.
Suppose my public address system needs to deliver 100 W of power maximum.
1. Efficiency 80%. It cannot consume more than 100 W/0.8 Watts
2. When it delivers 25% of maximum power, it must consume less than (100 W * 0.25)/0.69 Watts
3. When not doing anything (waiting for an emergency) it can consume 40 W
