I have pic related and it was working fine for a few years until

order the adapter it comes with

This, though in the process of plugging random fucking power supplies into the thing you could well have fried it. Did you even check the outputs of the supplies against the input requirements listed on the sticker on the back of the unit?

Well I've been taking it to stores around town and having the people that I'm assuming know what they're doing look at it, but I guess it's possible

When I plug it in, it doest make any sounds besides the screech. Like if I hit a drum pad, it doesn't make any change at all to the screech sound. Could that mean it got fried?

That could be a warning sound it makes when it's getting the wrong input, but I really don't know. Hope it's alright anon - hardware is fun until it suddenly doesn't work for no obvious reason.

I did a quick google anon, and the Alesis is a little unusual in requiring an AC input from its adapter - most output DC. Any idea if they got that right when they sold you whatever you're trying to use?

I didn't buy anything. I actually lost the adapter I got with it years ago and have been using a line 6 adapter since then which has worked fine. I accidentally got rid of that though and went to a few electronics stores and no one seems to have anything that turns it on without making it screech

They tried a bunch of different things on it so who knows what got plugged into it. In a few minutes I can look at the original plug where the problem first started though

So the drum machine doesn't say anything about what kind of power it needs besides 9v ac. Pic related is what I used when the problem first started

I know I can probably dig around an online manual and get an answer but I'm pretty busy right now, so I'm just hoping someone is nice enough to go out of their way and help me out

Also it might be worth mentioning that I also have a dl4 which is being powered by the adapter in that picture and could also be powered by the adapter I was using on the alesis, but the alesis only works with the adapter I got rid of

>>71785811
That's a DC output, which isn't what you want. I have no idea what that might or might not have done to the device.

And just as a guide, that solid line with dashes under it between the 9V and 300mA is the symbol for DC. AC would be a wavy line.

As that thread says, DC adapters are far more common, and it's not impossible that you took that device to someone who didn't even think to check whether you needed AC or DC.

Ok, thanks for the help. I'll call alesis tomorrow and see if they know what this means. Hopefully I don't need a new drum machine
