Cheap isolation transformers
¿ªÔÆÌåÓýI ran across something that I need to share.? I bought a two-pack of audio transformers on Amazon that work very well for the cost.? Works great to break ground-loop issues, hum, etc.? Cheap too¡ and a WHOLE LOT cheaper than the ElectroVoice transformers I usually buy at $225 each with my RE20¡¯s!? Tried it on my T41 and it does clean up the mic.? Not perfect but cheap. ? ? I have an audio board on the drawing board and it includes cheap open frame (full audio range audio) isolation transformers ? ? Dr. William J.
