I have an issue with background noises whenever I connect my pc to a bass amp (rumble 40) via aux cable. If I then plug in my headphone, all the noises are coming through the headphone as well with the noise also being amplified. The moment I unplug the cable between pc and amp the noises are gone.
This is are bearable if listening through the amp speaker alone, but sometime using the speaker is not always appropriate. Does anyone have a solution for this?
Summary
bass → amp - no noises
bass → amp → headphone - no noises
pc → aux → amp ← bass - noises
sndup(.)net/ygg2/ (noises sample) sorry, I don’t know how to embedded audio directly to the forum yet.
Yeah, sounds like you’re experiencing the dreaded “ground loop”. If plugging into the same outlet isn’t an option, there’s devices you can get that will stop the loop.
I was using the same power strip for both, then try to plug one (amp) into another socket from an adjacent wall outlet. The noises seem to be reduce a little, but still significantly annoy after something is played on the computer, the noises getting louder for a few seconds then reduced when its idling (happened regardless of where I plugged).
I then tried using my laptop, battery w/o power adapter and power w/o battery using same power strip as the amp both yield the same result, NO noise.
I was thinking the same thing, but I just found out that this issue doesn’t happened on my laptop w/ battery pulled out and using power adapter only (ac adapter plugged in the same socket of the amp) does not caused the same issue at my pc.
That thing is half the price of the amp, so I may saving it for now, thanks for the suggestion.
I had the same problem with my Rumble 100 @ikyokara
If I used the Aux in from my computer, no matter how I configured it, then it’s noisy. But If I just plug in my phone and stream music etc into the amp it’s completely silent.
I don’t use my amp to practice this way anymore but the problem you have is not unique.
Hi,
I was having the same problem with my rumble 40 and my PC.
It’s probably a ground issue
If I use the jack out on this pc it makes noise
Bought a usb to jack adapter and now the problem ( noise ) has gone
when you use a pc , always best to use the audio in and outputs which are in the rear side, as these are mostly directly on the motherboard.
the connectors on the front end mostly use unshielded flimsy cables to connect to the motherboard
I used my Fender Mustang Micro on vacation and happily streamed the play-along song via Bluetooth - which has terrible latency! But that did not matter, as the Fender has no noticeable latency for the instrument itself, if you listen through the headphone on the device.
It’s different for some devices when playing to/from PC.
Haven’t checked for the Fender (as I will replace it with a Katana Go) but both my Spark Mini and Go have terrible latency when recording.
This might be due to A/D conversion or sh#tty implementation otherwise.
A USB to analog adapter always does D/A conversion, so it might introduce latency, especially if it’s a low end device.
That is why I always check for recording latency on any new device.
Or skip trying to record through it and just use your dedicated DAI? I’ve got the micro also and found it unuseable to even play through into garageband. I keep it to use while I’m sitting in boring work meetings that I don’t really need to be a part of and it’s fine with an earbud in.
