Perfect to display speaker loudness (via lights)
I've been (ab)USING these smal audio 1:1 transformers to create my own line to signal level converters, so that I can hard wire siignal controlled equipment via any standard 4ohm/8ohm etc MAIN high-line-power feeds, for such things as operating speaker driven relays, LED 1.2vdc lights 9with diodes of course) to showcase the positive sine waves that ANY speaker is being fed, up to it's top/full power level, as individual "across-room power level indicators to make "speaker balancing super easy.
