My early hardware beta running firmware 7.5.0 r7863 (and I should note Erland & I both have very early betas; the circuitry changed enough on newer units that the plastic case shape had to change!) always hisses slightly, whether "on" or "off", about as loud as Erland notes. This seems independent of the Line In gain setting. It is much, much better than the hiss on a couple Tivoli Model One radios I tried. The Model One, despite all the praise it's garnered over the years, has has a hiss that's audible from 1-2 meters, and is noticeable even when Model One is playing music! I think this is likely to be fixed in software, at least hissing when "off" (and maybe that's why Erland & I see different behavior, maybe he's running Radio firmware that fixes the off hissing); if Radio isn't playing anything, including Line In, it should be easy for the firmware to turn off the amp. IIRC, there was a similar enhancement to the firmware for Boom after Boom was publicly released. I know of at least on Radio performance enhancement that hasn't been rolled out yet specifically because some folks like Erland & I still have the older hardware. It could well be that the best hiss fix needs newer hardware, and therefore won't be rolled out for another month or two (?), when all Radio early access testers have production level hardware. -- peterw http://www.tux.org/~peterw/ Free plugins: 'AllQuiet' (http://www.tux.org/~peterw/slim/AllQuiet.html) 'Auto Dim/AutoDisplay' (http://www.tux.org/~peterw/slim/AutoDisplay.html) 'BlankSaver' (http://www.tux.org/~peterw/slim/BlankSaver.html) 'ContextMenu' (http://www.tux.org/~peterw/slim/ContextMenu.html) 'FuzzyTime' (http://www.tux.org/~peterw/slim/FuzzyTime.html) 'KidsPlay' (http://www.tux.org/~peterw/slim/KidsPlay.html) 'KitchenTimer' (http://www.tux.org/~peterw/slim/KitchenTimer.html) 'PlayLog' (http://www.tux.org/~peterw/slim/PlayLog.html) 'PowerCenter/BottleRocket' (http://www.tux.org/~peterw/slim/PowerCenter.html) 'SaverSwitcher' (http://www.tux.org/~peterw/slim/SaverSwitcher.html) 'SettingsManager' (http://www.tux.org/~peterw/slim/SettingsManager.html) 'SleepFade' (http://www.tux.org/~peterw/slim/SleepFade.html) 'StatusFirst' (http://www.tux.org/~peterw/slim/StatusFirst.html) 'SyncOptions' (http://www.tux.org/~peterw/slim/SyncOptions.html) 'VolumeLock' (http://www.tux.org/~peterw/slim/VolumeLock.html) ------------------------------------------------------------------------ peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=70788 _______________________________________________ Radio mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/radio
