As someone who runs a Transporter's balanced outputs directly into active speakers (ATC SCM100As), here is how I went about things: 1. Connect balanced outputs of TP to input of speakers (of course). 2. Before playing anything, turn digital volume on TP right down. 3. Now start playing something, and gradually increase the volume on the TP until the loudness is a bit greater than you think you'd ever want. 4. Note the attenuation setting on the TP's digital volume control: this is approximately the amount of passive attenuation you need to insert between TP and speakers. (You might want to decrease the attenuation a little so you've got something in reserve for real head-banging sessions. For example, if the TP volume control is at -15dB when you get to the loudest you'd ever want, you might consider going for about 12dB of passive attenuation rather than the full 15dB). To work out the best resistor values to use in the attenuators, you need to know the output impednace of the Transporter (it's 100 ohms), the input impedance of your speakers (typically at least 10,000 ohms, often more), and the desired attenuation. Then you can start plugging potential resistor values into the spreadsheet available on the wiki page to find the best compromise effect on source and load impedances that give you the required attenuation. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=34484 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
