Noises from Aeros Gold Edition

Hey Brennan and All,

I have hiss-like, sizzle-like, and oscillating noises coming from my new Aeros Gold Edition running 5.2.1. The hiss is so loud that it distracts from the music. The signal chain is simply guitar, cable, Aeros, cable, amp. Nothing else. I have tried diiferent guitars, amps, cables and power supplies, all top end products. I have tried different power outlets, some dedicated circuits. I have tried turning off or unplugging electrical / electronic things around the house. I have tried organizing cables to reduce interference - separated, crossing at right angles, ferrite chokes, etc. The retailer sent me a second unit. Same noises. I’ve contacted Singular Sound Support. As I wait for their reply, I thought I’d see if the community has any experience with this. Again, the usual suspect, the PSU, has not proved to be my issue here. Really like the Aeros, just want it play nice in my rig. Thanks for your thoughts!

Quite unusual—not impossible, for two units in a row to have the same symptoms. Support may ask that you provide a video that also displays your pedal sound level and audio input/output.

Some common questions they may also ask:

  1. Does it hiss if using the Singular Sound PSU?
  2. Is there a cell phone nearby?
  3. Have you tried moving it into another room, perhaps one without any fluorescent lights?
  4. Would you consider trying the beta firmware to see if it still makes noise?
  5. You might be further asked to test by isolating the looper by disconnecting everything but headphones and assuming there’s no noise, plugging in one cable at a time, then your guitar and etc.

Hope you resolve it soon. Please let us know what it turns out to be.

Thanks for your reply @persist .

I’ve considered the sound levels a bit as you suggested. I can muffle or tilt the frequency of the hiss with different recording and playback levels, but they never remove it.

I get hiss with all PSU’s including the:

Factory Supplied 500 ma
TrueTone 1 Spot 1,700 ma
Boss PSA120R 500 ma
Boss PSB-1U 2,000 ma

I tested with no cell phones or “electrical emitting” devices around. That was one of my first thoughts too, that maybe it was some RF interference.

I tried different rooms, outlets, no lights on. No change.

As long as SS and the Retailer are fine with me trying the Beta I see no reason why not.

I can’t get the looper to drive any headphones I have from any of the outputs. Nor any stereo amp I have either. I need at least 6db more of boost, so I have to run it through my Yamaha mixer to drive those.

Thanks again for your reply!
