I'm a fan of the CV5000. Good amp for a 5,000watt load @ 4ohm. Hummm, in fact....I think I just found my new amp choice for my 24's.

Thanks man!
Thanks for the confirmation, both!


Glad to have been even a little bit useful, popalock I generally feel like I'm sucking up useful info from this place but not necessarily giving enough back, so I'm glad to have prompted a decision in your mind lol

Mine shall be stereo 2Ohms when it's finally up and running!

(On a side note - don't forget the CV5000 weighs as much as the moon... lol)


Can you tell us nosey people your intended destination country?

Yeah, I used to own a CV5000 a few years back. It's a heavy brute for sure. I'll be using one each @ a 4Ohm mono load for each 24".



I'll be heading to Doha, Qatar (aka: the hottest place on earth, aka: death valley's cousin, aka: 133°F in the shade) for a few years.

Salaam alikum! Kefaha lic? I love the Gulf State Region. I have been in out of that region for the last 10 years for work and leisure.

Enjoy Doha! I might visit Qatar next year.

I was just thinking about your shipping weight considerations! lol

That region is great for earning a LOT of money but the employment rules and also class hierarchy can make life tricky for those from 'outside', as I understand it. That said, english-speaking westerners are near the top of the tree so you will be fine!

It will be interesting to hear your views once you get out there, I would like to go myself

Good looking out on the shipping weight and the insight on the region. I'm pretty sure we will be able to utilize the military APO shipping system, so I'll take that route if necessary.

As for the region, the wifey and I each have about 4 years under our belts living and working in the middle east. I'd say we are more familiar with the culture than most, but we understand and respect that every country has subtle cultural nuances that make each unique.

We will definitely make the best of it.

I have an FP14K that died the other day while sound checking at a festival that we were doing. It ran all concert season last year and about 20 shows this year. powering Martin WS218X's one cab per side for a 4 ohm load. They switch between the Martins or EAW SB1000Z's depending on what rig I have out. My monitor engineer started smelling something burning and went over to the sub rack and one was not on and had the old let the smoke out smell coming from it. I have not even pulled it out of the rack yet to investigate as I just don't have time during my peak season but oh well for what it is worth they sound great when they work. Would I purchase more? well that is something that I would have to think about as I have not had an amp failure in over ten years consider it lucky or what ever but this is the first in that amount of time.

Most likely power board. Easy fix if you can solder. Easier fix if you have them send you the board and get a pro to do it.. Total cost in parts is probably $20-$50

A friend of mine was wondering if he would be able to drive 3 LMS Ultra in series using the FP14k in bridge mode. It obviously depends on the efficiency of the enclosures, but would it be doable? And more important, would it be advisable? He is thinking of doing 6 LMS-U and saving some doe by running two clones in bridge mode.

In series, 3 LMS would be 12 Ohm. Then with a bridged FP14k, it would see 6 Ohm and as I've understood it, it's stable to 4 Ohms in bridged mode. The amp would be at its own 16A breaker at 230V.

DAC/Preamp: miniDSP 4x10 HD and Mytek 192 Stereo DSD DAC
Speakers: JBL 4343B, JBL 4430 and JBL 120Ti
Amplifiers: Emotiva XPR-1, Denon POA 1500, QSC GX5 and Sanway's LabGruppen FP14000 clone
Sub: DIY LMS Ultra 5400

Hey Not, I'm finally fan modding mine and double checking first: I need one resistor per 60mm fan, no resistor for the 80mm fans, correct?

Thanks,
Doug

That's correct. So they're having me try a 1k resistor from the original 2.8k to drop the output voltage. Doesn't seem to matter though, the output voltage stays put at 204v.


Hello Trike,

Can you please post a picture of your power supply board?
There is a trimmer besides the power bank capacitors. The voltage is too high that is why the protection circuit is kicking in.
Has anyone successfully added a pot to the power board? If so can you tell me the part number that I would need to get one for my board? I measured my amp according to Johnson's instructions and it's nowhere close to his stated values. That might explain why my amp keeps clipping at moderately high volumes.

I've got a brand new Sanway Fp 14000 I'd let go if you want to replace yours.
