I find myself on a frustratingly bad run with my ae system at the minute after my TBD troubleshooting/issues...
As mentioned via email to Robert and I'm the other rains/cirrus thread, my module has a high pitched whine going on through the three outputs.
I'm used to a bit of noise in the ae system, but this is above anything else I have and is instantly noticeable - think broken drumkit01 levels of annoyance.
Does anyone else have this issue with it?

Did some testing to rule out PSU issues - removed from lower row, disconnected and fit module in a 2x16... Same noise issue on the output.

Check is in the making - sorry when my old ears don't recognize the noise issues...

No probs Robert - demo on the way and appreciate things slip through...

So when i put Rains through the headphone out on the power module and absolutely crank everything, I can hear the high pitch whine which is probably the same you're hearing (but sounds like yours is much more prominent). As soon as I back the headphone volume off it starts to drop away quickly to almost inaudible. Through a normal I/O i can maybe barely just hear it on headphones (it's more the sort of sound you sense rather than hear). TBH i find the headphone amp noisy at the best of times, so not at all surprised it's picked up there. I would guess some sort of filtering is not functioning correctly on yours  |

Mine's noticeable out of the main out of the mix module, no amping needed so I'm on the same page as you with a filtering issue. Somewhat fascinated to see if robert can pick it out based on what he says about his hearing! |

I'd appreciate some more input here - waiting (slightly impatiently I admit!) after sending Robert a second demo showing signal to noise on mine... no further reports from other users about an abnormally high s/n and haven't heard it on the handful of demos posted...

Rains noise 3.mp3 (814.28 KB) So Robert and I are trying to work out whether this is a module specific issue (to mine) or something that effects them all. Fwiw I haven't heard it in demos folk have posted, but we'd appreciate any feedback from users who already have the module... Please could anyone with a rains have a listen to the demo above and see if they recognise this behaviour or not. It starts with system noise floor between 0 and 1 seconds, system noise with rains attached from 1 second on - I hit the buttons since you can hear that noise from the rains change when the modes are changed. I recorded this section hotter than the next bit...
I then stimulate the rains at 15 seconds, let the rains ring out, almost to the point of silence at 24 seconds, but with the high frequency noise present. I then disconnect from the mixer module so back to system noise only.

well I’ve had mine since friday and done a good 3 or 4 hours of recording with it in a Vcase7 ( see dAEcksaver thread ) , not noticed any undue noise BUT i don’t use really high quality headphones particularly, i do power from a harleybenton 9v battery ,, the background noise i’m hearing from the mp3 you’ve posted seems similar to when i have O&C and a few other digital modules (TbD eg) in a larger case ,, which i didn’t think there was much i could do about , never really notice it when the noises are noising... I think Roberts nailed it with the mini power strip in this Vcase7 .. it seems very quiet considering there is 2 big digital monsters in there. i never thought the headphone out on the single unit power module was particularly good re: bkgnd noise.. could this be the weak link that needs an overhaul?? |

Just to be clear the noise from the rains is much higher than any high frequency noise I get from o_c, and the TBD modules I have, as can be heard present in the first second of system noise.
Edit: if you haven't noticed it I suspect it's not there - first thing I noticed.

Thanks for replying btw - do me a favour and next time you have the system in front of you check if you get a high pitch whine when connecting to your final out - stimulated or not. |

i don't have rains unfortunately but hopefully someone with it can let you know if they get it or not.
That high pitch frequency changing when Rains is activated is something I get sometimes when I have the Ae audio fed into an external mixer then route to an overdrive pedal turned up then back into the same mixer, when nothing is playing it gets like a line feedback loop.
It disappears once I start playing or turn the drive or volume down on the pedal.
I know separate to your issue but just mentioning in case there is a link or triggers a thought.

Hmm, depends how hot you are recording the first bit but that example seems quite prominent and doesn't sound like my module unless cranking though the headphone amp as mentioned before. Have to admit in the second half I can't hear any unusual noise at all. Might be my ears......

Have to admit in the second half I can't hear any unusual noise at all. Might be my ears...... That first bit is amped up through the recorder and computer - maybe 10 or 11db of gain in total. Second part isnt amped at all - I hear the same high pitched whine, especially when the signal fades out to silence; its a bit less noticeable when playing. Thanks for checking btw - appreciated. Anyone else can compare? I'm starting to wonder whether just sending the module back to Robert for him to compare might be the best idea, though it seems he struggles to hear high frequencies too. I have other 'noisy' modules in the system, but this one is significantly higher. |

After another ten minutes or so of messing I'm pulling this out of the system - it's an amazing module but I can't work with that level of whine/whir or whatever you want to call it: It's too high and I'm not risking tinnitus.
Not sure I've not really got enough here for Robert to establish whether there's a specific issue with my module so not sure what's next. I've mailed Robert to hopefully make a plan.

I have recently got Rains and seem to be having a similar problem to you with your original module. I've tried everything in terms of placement in the rack but the noise is the same even if its the only thing on the bus connected to the master module, unfortunately. |

From memory I didn't notice any, but haven't amped it up to check. I do get quite a bit of system noise in general but I've no issues with my newer rains. I guess whether we have the same issue depends on how loud your whine is? Check in with Robert would be my advice. |
