The wiki page has some good information and the "short answer" is correct. However, the long answer is quite incorrect in stating that the "right" amount of attenuation is a particular function of the amplifier rating/sensitivity (unless, again, your goal is to listen to full-scale sine tones continuously).
An amp is not going to fry because of clipping, and clipping isn't even the same thing as exceeding the power rating. For example one could play a waveform of high-amplitude clicks which would mercilessly clip the inputs but otherwise have almost zero power. And besides that, Transporter's outputs have a LOWER maximum voltage than most preamps! A preamp might go to 20VRMS or more (i.e. it could have positive gain). Also, any solid state amp worth a dime will have thermal and/or some form of signal limiting to protect it from damage. They don't just catch fire beyond some threshold (the way that speakers do!). So in summary: - forget the math. - set the attenuators based on your personal, maximum desired listening level. - set it even lower if you want added protection from family members cooking your speakers. - don't worry about overdriving the amp's inputs (in this case). I don't know how to make it more complicated. :) -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=63495 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
