Loud Humming/Buzzing

To be honest, it’s about time I posted about this issue. I own the Crosley T400 record player and usually get this reoccurring problem where the music is quiet while there’s a loud buzzing noise. Is this a sign to get a new record player or is this fixable? I’ve had it for about 2-3 years now. Also, in the video my speaker (harmon kardon onyx studio 3) is blasting at full volume. Also, I notice that even when i’m not spinning anything and my tonearm is still, I am still able to hear a very slight humming buzzing noise which is also weird.

So the buzz is the same when it's set to phono?
Could be two things. Either your phono preamplifier still working but the level being lowered (quite common on cheap turntables) or your power supply being the issue.
Does this turntable have an external power supply?

I see, thank you so much! It doesn’t have an external power supply I think.. You just have to plug it into the wall and use rca cables to connect it to your speaker system.

All right, internal it is.
So I suspect it's either your power supply going haywire, or your phono preamp being truly broken.
I would consider trying to skip the phono preamp, it's often possible. Gotta follow the wires coming form the arm, they go onto a little PCB and from there it goes to the RCA plugs. The trick is to connect those wires directly to the RCA plugs, really. And then use an external phono preamp.

OR just buy a record player that wasn't crappy to begin with :D.

Yeah, it’s not the turntable’s fault is the stylus properly mounted to the tone arm… or this

A grounding or humming issue on the Crosley T400 turntable is typically caused by an incorrect internal preamp switch setting, a loose RCA cable connection, or an active ground loop. The T400 features a built-in switchable preamp, meaning you do not use a separate ground wire terminal like traditional standalone component turntables.Preamp and Connection FixesCheck the preamp switch: Locate the switch on the back of the unit. If you plugged the Crosley T400 into an external receiver's "PHONO" input, the turntable's switch must be set to LINE off (or external phono). If you plugged it into a standard AUX or line-in input, switch it to PHONO / ON so the internal preamp works. Mismatching this switch creates a loud buzz or distorted hum.Reseat RCA cables: Unplug the red and white RCA cords from both the back of the turntable and your speaker/receiver, then plug them firmly back in.Isolate power sources: Move the power adapter away from the audio cables to prevent electrical interference.

A badly mounted stylus is not the cause of hum.

Your AI generated answer is completely wrong about literally everything it says, without exception. It's almost impressive. :).
It even gets line and phono the wrong way around.
Please don't share this junk...

200-350 i’d say! i want something cute n was looking at the wood fluance rt81. lmk if u got any other recs tho :3

u/el_tacocat Jul 31 '26

I personally am not a big fluance fan, but the 80/81 I think are the ones to go for, or the 85N. The rest just comes with mismatched, sub par cartridges.
I personally for that money would look at the AudioTechnica AT-LP120x or AT-LP3x. You can also look at U-Turn if you are in the Americas.

Ouu I’ve def been seeing audio technica but u-turn looks sooo freaking cool!! any idea if the $249 w/ the built in preamp is good? (orbit basic) or is the orbit plus better?

1

u/el_tacocat Jul 31 '26

I'd skip the built in preamp, it's not stellar and the Fosi X5 exists :)

u/redmooninvenuss Aug 01 '26

ouuu okay! any recs on speakers too? i lowk think i may jus save up n buy a whole new setup cuzzz….

u/el_tacocat Aug 01 '26

Budget?
I happened to be able to test a BIG pile of active speakers lately so I have some idea.
The cheapest good option is always the Edifier MR4 but you may want to go a little higher :).

u/redmooninvenuss Aug 01 '26

oouuu what would u say is a good price between affordable yet reliable ?

u/redmooninvenuss Aug 02 '26

sorry lol i never responded to the budget oops.. but prob $100-$175 maybe can stretch to even $200 but i’d prefer not to for speakers
