Yes: that's the required LOAD impedance, ie. the input impedance of the device you're driving (the speakers). The output impedance of the amplifier itself (the SOURCE impedance) will be significantly smaller - as opaqueice says, probably less than 0.1 ohms.

High impedances mean that less current gets passed, which of course means lower power. Speakers need to have a fairly low impedance so that sufficient current will pass that you'll get a usable loudness. And in turn, this means the output impedance of the amp must be extremely low. -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
