Re: [SlimDevices: Audiophiles] rolling back slimserver
If you have other sources, you could use the Inguz DRC plugin. It can be configured to invert absolute polarity. You don't need to make any measurements or anything, just follow the installation instructions, then select the Invert Polarity room correction filter that is provided. Works for me, although whether you can hear the difference is another issue. -- parrydave *modded squeezebox 3/arcam cd92t/arcam a85/arcam avr300 dynaudio contour 1.3mkii/dynaudio focus 200c/mk k-4/rel q150 pioneer pdp-507xd/sky+/harmony 525* parrydave's Profile: http://forums.slimdevices.com/member.php?userid=6079 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] rolling back slimserver
yes the bolder analog mod removes the analog op-amp which effectively reverses the phase of the unit. thus they recommend rolling back to firmware 15 which as i see it can't be done on a mac. as for whether or not you can hear it is up for some debate i guess. wayne from bolder said he can easily tell when his speakers are out of phase, i know others have a much harder time (hence the need for hundreds of dollars gadgets to tell you whether or not your in phase or not). there also appears to be a cult following for firmware 15, who seem to believe it sounds better, but there's already one psychoaccoustics thread started somewhere and i don't want to start another... -- ratso ratso's Profile: http://forums.slimdevices.com/member.php?userid=11493 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

And that change is on the analog outs. So you can reverse the wiring of your analog cables between the SB and the amp/preamp/receiver/whatever. $10 worth of parts at Radio Shack and you can dereverse (yes, I made that word up) phase in hardware. No active components, pure audiophile grade mod! If you do it on those cables, other sources won't be affected.

You can't change the phase of the RCA outputs by rewiring them! That would work with a _balanced_ connection, but you can't do it with the RCAs because their sleeves are both at ground. You _can_, however, invert phase by reversing both speaker connections. ratso: the suggestion to go back to fw15 (now over two years old) is patently ridiculous for reasons I don't have the patience to elaborate right now, but if you search the archives it's all been covered. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] rolling back slimserver
i have a question that could go in many different forums here, thought i'd try it here. bolder suggests using version 1.5 of slimserver to correct for phase issues (i think that's right, audiocircle's server is down right now and i can't pull it up). anyways, the program written to roll back to earlier slim builds is for pc and i have a mac, osx 10.4. anyone know another way to do this or have other suggestions, i really do not want to switch my speaker wires every time i change inputs. -- ratso ratso's Profile: http://forums.slimdevices.com/member.php?userid=11493 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] rolling back slimserver
Versions of the Squeezebox2/3 firmware after 15 -corrected- phase. Pre-15 the phase was backwards. If a modder reversed your phase, then you have a choice: 1) Correct it by reversing the phase on your cables. 2) Correct it by using an ancient version of the firmware that is no longer supported and doesn't support things like OGG or Squeezenetwork. If no one reversed your phase, then ignore the silliness. I will leave it up to you which solution you wish. -- snarlydwarf snarlydwarf's Profile: http://forums.slimdevices.com/member.php?userid=1179 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] rolling back slimserver
yup of course all my files would also be OGG! oh well. maybe we'll get lucky and sean will add an optional build we can download that reverses phase. i give this place a lot of credit, they have always been pretty open to have people poking and prodding at their device. very commendable. -- ratso ratso's Profile: http://forums.slimdevices.com/member.php?userid=11493 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] rolling back slimserver
Did someone mod your SB and reverse the phase? That is the real question... And if they did, just un-reverse it at the cables.

But more importantly, there is no *real* reason to want to use ancient firmware such as version 15. And I can't imagine wanting to use SlimServer version 1.5, I've been using SlimServer for years and it started in the 5.x series then. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Of course, if you have a Squeezebox you wouldn't need anything else, so I guess that's a moot point. ;) -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=36715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
