Audio / Level 1
70/100 V amplifier power planner
Size a distributed-audio amplifier from actual transformer taps and explicit spare capacity.
FormulaPamp ≥ (n × Ptap) × (1 + H)
Assumptions
All loudspeakers use the entered tap and are connected to one compatible 70/100 V output.
Limitations
Does not predict SPL, cable loss, circuit redundancy, emergency-system requirements or per-channel constraints.
