We must keep in mind the possibility that we're being reeled in by a prankster over this (in which case I applaud sleepysurf's mischief - we can all do with some light relief around here).
But if we are to take what he says at face value, my reading is that the extender is NOT a microphone-based device. He says it's wireless, and I'd expect it to be RF rather than infrared (otherwise it would only work in line-of-sight). If that is the case, then the implication is that when the analogue output is not muted, the SB generates some amount of RFI that triggers the extender, and this interference goes away when the analogue output is muted. That suggests to me that the SB's internal DAC is the source of the RFI. Perhaps if the DAC receives just a stream of zeros, it doesn't bother to do anything. Or maybe even the Squeezebox firmware switches off the internal DAC when the analogue output is muted. Maybe Sean can comment on this. As for getting the extender triggered by turning up the level on the Benchmark DAC1, then we can conclude that even this exalted device can generate the necessary RFI if pushed far enough, so it's not as if the SB's DAC is somehow deficient in this respect. -- cliveb ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=26332 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
