Now I'm going to show you my amp-odissey so far(I'll try to summ-up as best as I can with my poor english). 1)I bought a "BRAND NEW" EBS cab 4x10 4ohm 1 month ago 2)I bought a "BRAND NEW" EDEN Navigator(pre-owned;as-mint:I tested it very carefully before buying). 3)I received an EDEN Wt1000 power-amp from Basscentral quite 3 weeks ago. Here's the problem: If I used the power amp in bridge mode(1000 watts @4 ohm)I got a terrible distortion,even at very low volumes.While,if I used it in MONO(450 watts @4ohm;A channel only),everithyng is OK. So here's what I did 3 weaks ago: 1)I called to Eden,to see if they could understand where was the problem:the told me that it was in the power-amp. 2)I called to Gard at bass-central:he said they had no responsability,because the power-amp had just arrived from Montrose(Eden);and after this they had immediately shipped it to me. 3)there were no visible damages on the packaging and on the surfaces of the power-amp:so I didn't waste my time with UPS 4)I called to Eden once again:we agreed to try to repair the power amp here in Italy,to avoid other shippings,shipping costs,other wastings of time 5)I brought the power-amp to my tech guys:they looked at it,tested it,and then called to Eden once again:they all agreed it was all due to the preamp-section of the power-amplifier 6)a new preamp-section for the WT1000 arrived yesterday from Eden:my tech-guy installed it.Everithyng seemed cool now.He tested it and was fine;we run all my rack(with the same cables,the same connections)to his SWR Goliath(8 ohm) 1ERFECT,both in mono and bridge. 7)I arrived home...DISTORTION in Bridge mode ON MY EBS!!!!!!!Me,CRAZY..... 8)OK:then the problem is a)or in the EBS... (but why is it ok then in mono mode?If a speaker is bad,it is always bad....I mean: of course there are 550 watts more in bridge,but the distortion comes at very low-volume,while huge volumes in mono are ok; b)or in the power-amp, only if used in bridge mode with a 4 ohm cabinet only(because remember that everything was cool with an 8ohm SWR) 9)So I went to the shop where I bought the EBS:I wanted to compare what was going to happen(distortion) on my EBS,with what would have happened with another one they have in store;I thought:"if mine ones will distorce,while the "in store" one won't,than I will have found the problem,and I will use my EBS Warranty" .......eh!!!!Do you know what:I tryed EVERITHING AS THE SAME(BRIDGE;MONO;Same cables,same connections,same settings,...),and NO DISTORTIONS,neither on the "in store EBS",neither on MINE ONE!!!! :mad 10)To-Night:reharsal...........DISTORTION AGAIN in BRIDGE with my Ebs!!!!!!! For the once who have been able to read so far: HELP!!!!!GIVE ME AN IDEA!!!!!! .May be is the cable I use for connect the power amp to the cab(May be it is ok if I send 450 watts through this cable;while it isn't if I send 1000 watts through it?)???May be it is the cab?May be it is the amp?But,why is the amp always ok with the SWR cab?Why the EBS is ok in mono,and not in bridge?....and why EVERYTHING was perfect then,at the sore I DON'T KNOW WHAT TO THINK;AND TO DO!!! I'm desperate. Thank you for your patience.
