Why match impedance?
Impedance matching maximizes power transfer from the source to the load and prevents signal reflection.

- 1Enter the source impedance (e.g., output of an amp).
- 2Enter the load impedance (e.g., speaker).
- 3The calculator will show the required turns ratio.
Transformer Matching
The turns ratio (n) of a transformer is the square root of the impedance ratio.
n = √(Zsource / Zload)Variables:
ZsourceSource ImpedanceZloadLoad ImpedanceExample
Tube Amp to Speaker
Inputs:
Source:5000 Ω
Load:8 Ω
Steps:
- 1.Ratio = 5000 / 8 = 625
- 2.Turns = sqrt(625) = 25
Result:
25:1
