Crown Audio Calculators: Line Loss

A useful calculator for designing audio systems with Crown amplifiers.

This calculator provides line loss with 2-conductor cable on a constant voltage line.

Equation used to calculate the data:

Ploss = 10 * Log [1 – ((2 * RL) / (2 * RL + (Vline squared / Prated))]

RL = (Rref / 1000) * D

Where:
D = length of wire used

Ploss = ower loss in dB

Prated = power driven on line
RL = wire guage resistance
Vline = voltage on line
