In Reply to: RE: 4 ohms vs. 8 ohms - Lowers Supply rails posted by BigguyinATL on March 15, 2012 at 06:57:05
Stereophile said there was a 45 degree phase shift in the lower frequency region where the impedance also dipped to four ohms...
Maybe he *should* use the "LOW" switch, or use "HIGH" with caution...
Thanks for chiming in. And thanks for explaining what the switch actually does... it limits current by reducing rail voltage... makes sense!
Cheers,
Presto
Follow Ups:
These usually use a dual tap transformer and a switch. The other way is to actually have a curent limiting circuit employed on the signal - it keeps the rail voltages the same but limits the signal voltage swings. Realy cheap.
Three most important things in Audio reproduction: Keep the noise levels low, the power high and the room diffuse.
