Make sure your useng a balanced out put from your mixer not phono.

I reckon there is a good chance you've got a dodgy mains transformer, or perhaps a blown internal fuse. Sounds very much like the problem is on the AC input board.

How should i connect my subwoofer- is it directly to the speakers or amplifier?t


I'm assuming that you are using a standard amplifier with L and R speaker outputs if a stereo Amp.... or L and R and SUB standard RCA output jacks. If it is a more complicated setup, having surround sound speaker jacks, then look for a SUB OUT jack or plug.
Some Subwoofers are self-powered, having their own, built in amplifier especially designed for that model. Sometimes they require a SUB connection and a power supply to the 110V AC house power too. These sometimes need a connection to a standard 3.5 mm HEADPHONE jack output plug. If it's this type, then the front of your amplifier could have one. Either way, the musical signal from amplifier to the subwoofer must be available on your Amp AND be received by the type of subwoofer you are using.

My powered sub is humming


Does the humming go away if the cable is plugged in but you wiggle it? May be a bad connection on the input jack.

I just got brand new jamo sub 650. But very next day Their is a power turn on problem with the product. I have changed the plugs also I got the monster power cord still sometimes it does not turn on and...


Hi.
This sounds like a resistor problem.
Most likely, when it got shipped to you, it jarred the electronics inside.

Now, because there are several resistors inside of it, I don't recommend just trying to replace them yourself.
I would take it to Fry's, Best Buy, or Radio Shack.

They have electronics repair technicians, and they know how to find the bad resistors quite easily with their testing tools.

I say resistors, as opposed to capacitors.
If it was that, the unit would turn on, and then always shut off within a couple of seconds.

I hope this helps you know what is going on, and I hope it gives you some idea as to what to do next.

Good luck to you, and have a good day.

Bought a used Martin Logan Dynamo subwoofer a couple days ago and have a very loud hum when the ac cord is plugged in, even if the speaker is not connected to an audio source. The "hum" can be heard in any...


Neither the amp or the sub have grounded power cords.

I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.

With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.

I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?

Works fine. Now I have the ML powered from the wall and working normally.

A few more questions-
Does the sub hum without anything plugged into it except for power? If it makes a real loud hum almost a squeal then I think the rca cable between the receiver and the sub is dead shorted and needs to be replaced. If it's more of a low level hum, then it's a ground hum caused by many things, ie........the receiver and the sub being on different power circuits in the house.......sometimes diconnecting the cable tv feed as it enters the room while the sub is connected and humming to see if it stops........the easy fix sometimes is using a 3 to 2 prong ac adapter but lifting the ground on such a powerful amp could be a fire hazard.

My computer sound system


Most likely the sub has the crossover in it, most likely the 2 input cables from whatever device you want to play through the system will plug into the sub then the 2 speaker cables will come out of the sub and go to the speakers, just be sure to have everything connected into and out of the sub and make sure the power cords for the speakers and sub are plugged in, I am assuming this is a self powered system wich means the amplifiers are built into the speakers and sub.

No sound


Willing to bet you've blown the amp, or fused the coil. I've had it happen twice, apparently when running off a power source that apparently couldn't handle the load. Hope it's under warranty - if so Loud Technologies (deals with all Mackies warranty stuff) should be able to replace the unit. Otherwise, you'll need to take it in to a service department and have it checked out.

Good luck, you'll have to arm wrestle with them to get them to replace it.
