Axiom Home Page Forums General Discussion Technical Questions No power EP600

I have two 600's which were in storage for a few months (way too long) while I finished my home theater. When I set them back up they both powered up fine but the next day I found that one had no power. I tried swaping out the power cords and fuses but they both work on the one and not the other I also tryed other outlets which did not work either. Any ideas??

Thanks

A bad amp, call Axiom.

Sorry guys found the problem. thought I would pull the voltage regulator to see if there was a problem and found two fuses that I didnt realize were their and one was blown. does this happen often? if so I'm not sure why? other electronics seem to work fine in the same outlet.

It's working now?

Swapped out the fuse and blew that one too??

Could it be it's a problem with the power to your theater? Much as I know you don't want to do this, have you tried moving the 600 that keeps blowing to a different circuit in your house to confirm whether plugging it in there causes the fuse to blow as well? If so, it sounds like a problem in the amp. If not, it might be the power to the room.

If you find it is not a sub-amp problem, you might consider looking at a power center, (Pure AV, Monster etc.)which will give you the option of delay on/off switching which will be easier on the circuit. Maybe a stupid question, but is the cable going from your AVR to the sub ok? Considering the limitations of positioning of the subs, I don't know whether this would be an option for you, but in my case with eight pieces of equipment including two multi-channel power amps on a regular 20 amp circuit, without the power center, I probably would be blowing fuses every time I turned everything on.

I had the same sub plugged into the same outlet about 3 or 4 months ago and it worked fine. I dont have a surge protector or line conditioner plugged into it. are most people doing this? if so I will need to buy 4 of them to protect my whole system. I was thinking of getting one for everything in my equipment rack but its a good 20ft from one sub and about 30ft to the one with the issue.

Sent an email to axiom last night and got a reply to replace both fuses I did this and they blew again. So tonight I called and talked to Brent Tombari who was very friendly and awesome to deal with he said that they will be sending out a new amp. I'm so amazed at the service this company provides this is the best I have been treated by any company to date. sure makes you feel good about purchasing their product. not to mention the steller sound quality that they produce.

Welcome to Axiom CS.

Playa - to answer your earlier question, no, I don't believe you need power conditioners on even one of your power locations unless you know for a fact you have electrical problems in your house. That doesn't sound like the case, so I wouldn't drop the money there, especially with a new amp on the way.

Jason

Thanks for the reply Jason. What is your opinion on running conditioners for the rest of the equipment? AVR, DVD player, ect... Do they realy help in any way?

I have a PF60(Belkin) and I haven't found any difference, other than it's kind of fun to watch how much the input power fluctuates through out a day.

It depends a lot on needs. My Soundbridge had a lot of interference. I got a PF30 and it disappeared. For the rest, I did not see/hear any difference (most of my sources are now connected to it, but not the amps--which includes the subwoofer).

For me a power conditioner isn't a factor for sound or video but since I have several pieces of equipment including two multi-channel power amps, with all the cables hidden behind the racks it all but eliminates the hum in the speakers. In my mind, though, the biggest plus is the delayed and sequential on/off capabilities which reduce the power surge when everything is powered up and prevents pops in the speakers caused by the amps which would occur if they were not sequentially powered down.

Sounds like it's still a worth while investment. What is the pf30 worth?

I see retail they are $199 (pf30) on the belkin site What did you guys pick yours up for and why did you settle on the belkin?

I bought mine from e-cost($326cdn delivered). I trust the belkin name, the PF60 had the highest joule rating I could find and I liked the blue display.

You could also look at Panamax, they make some very good ones as well. Some reports say they are better at noise reduction than belkin, but they have a lower surge joule rating.

Got mine at the link below (Canada) and picked belkin because of comments on the forum. I was not seeking magic, just getting rid of some interference (not groundloop) for the poorly electrically designed Soundbridge (at leats on that aspect).

Personally, I think this is one of those things you buy "just in case" it helps. I thought about it a lot when first setting up my system and decided to wait to see if I noticed any shortcomings before putting the money down on one. Once I'd plugged everything in, I really couldn't detect any problems, so I decided not to invest. I do have a good quality surge protector into which everything is plugged, but that ran me about $30, not ~200.

If I bought one now, I think the primary reason would be aesthetics, but that's just because I don't notice any problems in my setup. If you're like Eric (efalardeau) and you do have issues from interference, then it sounds like a very good investment.

The only general advice I'd offer is to price shop. When I was considering these, I found the retail prices on all of these power conditioners are an absolute joke. 50% off retail was pretty normal when I was shopping.

At the time, this was the one I was going to buy if I picked one up. Belkin AP 41300FC12. Price = $250, Retail = $750.

Here's a link to the NewEgg page that contains significantly more information on the specs of this unit.

It's gotten even cheaper since then it appears... $196 on Amazon.

Wow thanks for all the info guys.

I went the same route as you Jason. I plugged everything into a surge protector to see how it would work. Everything seems to work fine but I do have subwoofer hum and I havent tracked down the source yet. The subs hum worse when the ground screw is removed from the amp and Im not quite sure what this means. Is it a ground loop or am I just picking up intrference somewhere else?

I would bet it is a ground loop. Buy a cheater plug (3 prong to 2 prong adapter). It will cost you about $1. If the cheater plug gets rid of the hum then you have a ground loop within your system.

Also check if the the subwoofer hums if it is only connected to the power outlet (with nothing hooked up to it). If that is the case there is something wrong with the sub.

Dr. House

Not to sure if you are talking about XLR cables but if you are I cant do that my AVR only has the RCA type of pre-out for the subs or are you just talking about the power cable. Correct me if I'm wrong but I thought removing the ground screw would do the same thing as the 2 prong power cord which is just removing the ground.

My only experience wiith ground loops was after adding a subwoofer with a 3 prong power cord. I have never owned a subwoofer that has a chasis ground screw on the back of the amp so I am not sure if that would subsitute for a 2 prong power or not. Hopefully a 600 owner chimes in with their experience.

Here is the troubleshooing guide for the EP600 in the meantime.

Good luck,

Thanks for the link.

I had a hum that was only removed by using a cheater plug. The ground screw helped, but didn't totally remove it. I know the cheater plug is not a great idea electrically, but it does work.

I find it interesting that most of the other subs I have looked at only had 2 prong power cords, now I am guessing it is to stop the ground loop hums.

If you find you do have a ground loop issue mastaplaya and if you do not feel comfortable defeating the ground, I posted below an excellent article by Alan Lofft which shows a methodical way of tackling this issue.
