Hi
An audio output amplifier rated 4 to 8 Ω, outputting 1 to 20 Watts (~2Vrms to ~11Vrms) depending on its program material and volume adjustment is desired to produce a signal line with all its dynamic range at not more than about ~6Vrms.
Was thinking on using double zeners sensing the audio level to drive series pass transistors self-biased bases to limit current when level exceeds 6Vrms, but would not have dynamic range, would behave as a clipper.
Any suggestions on how to attenuate all the audio dynamic range only when exceeds ~6Vrms ? If possible, with a passive circuit that would be connected to the speaker line far away and derive the 'limited' level ?
It is not a 70V installation, even when a 70V transformer properly connected there would sort of produce the desired attenuation.
