Setting the volume at 100 will give you the best signal-to-noise ratio, so that's the general recommendation. Just don't turn your amp's volume too loud! With Sqeezceenter 7.1 and the new firmware it includes, you can use the "fixed output level" option in Squeezecenter to lock both digital and analog output at volume 100. I think you don't actually lose detail until volume 70, but 70 on the SB3 is about -15 dB, so at 70 you've decreased the S/N by 15 dB. Use the "Advanced Search" feature on these forums to find posts by user seanadams (company founder & Squeezebox designer) for the best info on the subject. If you're not using Squeezecenter 7.1 or if you want to lock the output at a lower volume level, see my VolumeLock plugin. Basically, once you get the volume where you want it, you can use the IR remote or Web interface to ask VolumeLock to lock the output. If your amp has an infrared remote control, you should also look at Felix Mueller's IR Blaster plugin. I use this on one SB3 that's hooked up to a mini stereo. IR Blaster fixes the Squeezebox output at a certain level and passes volume up / volume down commands to your amp once you acquire & set up an "IR blaster" infrared dongle. -- peterw http://www.tux.org/~peterw/ free plugins: http://www.tux.org/~peterw/#slim AllQuiet BlankSaver ContextMenu FuzzyTime PlayLog PowerCenter/BottleRocket SaverSwitcher SettingsManager SleepFade StatusFirst SyncOptions VolumeLock ------------------------------------------------------------------------ peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=50544 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
