情境
A stereo line-level source feeds two isolated outputs per channel using 1:1 audio transformers, preventing ground loops between multiple amplifiers.
這張圖裡有什麼
看懂背後的決策。
01
Use 1:1 transformers per output to break ground loops
02
Keep secondary circuits floating to preserve galvanic isolation
03
Terminate each isolated output with a load resistor matching typical line impedance
Reuse for passive stereo distribution or isolating ground loops when driving multiple amplifiers, recorders, or powered speakers from a single line source.
