Interference from Central air and Washing Machine?

[E-A-G-L-E-S]

I get burps out of my sub when my central air and/or clothes washer goes on or off...even sometimes "during" a cycle when it shifts what its' doing?
Nothing out of my speakers though.

What sub is it? A lot of sub amps a class D. That allows the designer to produce despicable power supplies not worthy of the name, to shave dollars.

The power supply of your sub is not able to filer out the spikes from the motor starts and the switching of the appliances.

Either a better sub amp is required or suppression circuits need to be added to the offending appliances.

I doubt you have that on the same circuit as the appliances, if you do get a dedicated circuit for the EP 2500. If it is on a dedicated circuit, then for some reason the spikes from your appliances are getting through the EP 2500.

In that case you will have to use suppression on the appliances. It is always best to deal with interference at source, rather than at the affected device.

To be honest, I'm renting and I'm not sure if it is all on just one circuit or not.
I called my lanlord about it 2 months ago when I first thought of building a diy sub and he has never gotten back to me about it.
I don't know where to look.

If it was all on the same cicuit and there's just too much juice required, would the suppressers help at all?(Not sure that even if I paid I could get a dedicated circuit installed if needed?)

Behringer EP2500

I sense a change in tone to your post once you read that it's the beloved Behringer EP2500.

Chances are, they are on the same phase.
One thing that might help.
If you know how to work in your electrical panel, or know someone that does.
First find out what breaker the sub amp, washer, and AC units are on.
If they are on the same phase; swap the sub amp's breaker position, with the breaker directly above, or below it.
That will put it on a different phase. It will help if the other phase is overloaded and not balanced.

As for the AC unit:
Even though the AC unit uses both phases, there is still a chance this will help, if the phases didn't have balanced loads.

You can also ask your wife or girlfriend, if she will let you do the laundry, after you watch a movie.

This is something I'm going to find someone with more knowledge of than me to help.
Thanks for the help.
I have access to the panel in my spare bedroom, but no expeience or knowledge on the subject.

I have never seen or handled a Behringer, but it seems to be in favor. However the fact that it can behave in this manner even given the fact he is in an apt, probably indicates the unit is not top drawer. I will stick to Quad. After 50 or so years, I see no need to change. Personally, I don't think there are more stable trouble free amps, able to maintain specs year after year on the planet.
