Better late than never:
I had always said I would make a simple guide/visual on how to bridge the NC502MP/NC252MP externally without modifying the internal wiring. Here it is!

1) Acquire a Female to Male Y-Splitter
2) Leave one Y splitter end as-is (do not modify)
3) Unscrew the other Y splitter end and swap the wires for Pin 2 and 3 (will need to solder)...see attached picture for pin orientation when looking directly at the Male end
4) Once modified, attach the unmodified Y splitter end to Channel 1 and the modified Y splitter end to Channel 2
5) Attach the Positive (Red) Channel 1 binding post on the amp to the Positive (Red) terminal on the speaker
6) Attach the Positive (Red) Channel 2 binding post on the amp to the Negative (Black) terminal on the speaker
*Both Negative (Black) binding posts for Channel 1 and 2 on the amp will remain unused

Attached is a simple diagram

If the DIY route above is not doable, an easy route is to order a Female to Male XLR Y-splitter from Blue Jeans Cable and ask for one of the Male ends to be wired out-of-phase (you would need one such Y cable per bridged channel).

Looking forward to the pictures and review. I would like to see a 2 channel unit with VU meters. Maybe in a case like this. You could just use XLRs for the Amp inputs and RCAs for VU meter inputs if you do not want to mess with meters in the audio chain.

Hey all,

Long-time A/V enthusiast with an extensive history on the AVS forums and more recently following this site for all the technical and objective expertise. After months of looking for the best amplifier setup over the summer, I went a DIY route and built a 4-channel NC502MP and 6-channel NC252MP build using Modushop cases. One of the reasons for the DIY route was the lack of sellers in the US, and at the time of my needs the offerings of US sellers was limited.

I found putting my amplifiers together a fun "hobby"/relaxing during the nights after I got home from school (working on a PhD currently). So I got to thinking, could I offer a no frills, low cost option for US buyers without much overhead/need to charge more than necessary to turn a small profit while providing a quality product? After a couple of weeks of spitballing and working on a case prototype that is cost effective, I believe the answer is yes.

I don't have a website yet or any official pictures (waiting on the cases to arrive and put one together) but I have official cost for my initial offerings settled and can at least confidently announce the following configuration and pricing:

6 channel NC252MP, XLR inputs (Neutrik), 12v trigger, Power LED, Black aluminum 2U case (17" wide, 12" deep) = $1249 shipped
4 channel NC502MP, XLR inputs (Neutrik), 12v trigger, Power LED, Black aluminum 2U case (17" wide, 12" deep) = $1049 shipped
4 channel NC252MP, XLR inputs (Neutrik), 12v trigger, Power LED, Black aluminum 2U case (17" wide, 12" deep) = $849 shipped

These would be my first offerings as they can all fit in the same case. Within the next few days I will have a prototype case that can fit an 8 channel NC252MP or 6 channel NC502MP offering. And last offering would be a case that fits a 2 channel NC502MP or 2/4channel NC252MP offering (so you aren't stuck with the larger 17" wide case for a 4 channel NC252MP). Once the price on these cases are official, I will post pricing.Ohio

My start-up is going to be slow at first. Right now I only have NC252MP modules on hand (the 502's are on backorder). And I am keeping a low stock of parts until I can see how much interest is out there. As I said, this is not going to be a main source of income or business for me. More small profit margins since this is going to be a hobby endeavor and an entry level offering for those in the States. If it gains traction, a website may be up and running by the end of the year. Until then I am open to PM's on here or my email address (if I am allowed to provide it?). As long as I have the modules in stock, turn around time for building would be 1 week maximum.

I have a 6 channel NC252MP offering officially sold to a fellow member on here who lives close to Amir. The plan is once he receives it in a few weeks he is going to ask Amir to review it. I hope to pass but am also open to being tore down if it means bettering my offerings.

Ohio guy? I originally hail from Cleveland.

Nice....Toledo area here. Thought Buckeye Amps would be a simple name and it was available when I registered the business.

Hoping I can provide good quality amps for a bare minimum price margin. Will wait to see what Amir finds if he reviews the one I make for @Lonestar1027

 

[DWPress]

I am very interested indeed. Currently have 3 tabs open deciding on either a Audiophonics, Nord and VTV 4 channel NC252 build. I'll send a PM on top of this post. Looking forward to pictures and actually a 17" case is more ideal for me than something narrower.

 

[Buckeye Amps]

For the time being, here are render pictures of the case. It will be finished, including the side panels, in a Jet Black Powder coat (Medium Gloss, Smooth). The bottom panel has holes cut for direct mounting of the modules. Which also means if you ever want to swap out a module (say change an NC252 to an NC502 if you need more power later on) or add a channel (say you buy the 4 channel NC252 that comes in the 17" case there are already holes in the bottom to easily mount a third module later on down the road). Again, trying to keep the costs down so offering cases that can be used for many different configurations helps. And again, the unused XLR and binding post cutouts will be covered.

It is aluminum all around. 1.6mm top and bottom, 2.6mm front and back.

I apologize to any potential OCD customers (which is myself sometimes) but I decided on the Power LED being in the bottom left front corner instead of dead center.

 

[Matias]

Nice, good luck!

 

[Lonestar1027]

Excited to put this amp to work and get it tested! Looks to be a great value and @Buckeye Amps has been a pleasure to work with.

 

[DWPress]

I'll echo @Lonestar1027 now that I've spoken for Buckeye amp serial number 2!

All my conversations with @Buckeye Amps has been very pleasant today and the last message exchange verified he's figured out the "pin-1" implementation. When this thread gets 30 pages long point them back to post #9

This is gonna be so sweet to output 4 channels at 200W balanced from my forthcoming Okto DAC8PRO. A big step up in SQ from my miniDSP4x10 and cobbled together amp collection.

Moved question to DIY thread

 

[Buckeye Amps]

First post updated with all offerings and pricing, from 8 channel NC252MP's down to stereo NC502MP's.

 

[Buckeye Amps]

It was brought to my attention, but for the 19" case offering, it can accomodate two NC252's and a single NC502. I won't make it an official offering, but it is an option I can put together for the few who may want that.

I have another order of NC252's on their way and will be putting in orders of the larger and smaller cases tomorrow. Waiting until November to order NC502's as they are on back-order and my capital at the moment isn't that high yet (as stated, keeping a low overhead at first due to the slim margins I am trying to offer at).

Thanks all for the interest and even just looking at this thread. I am open to critique and suggestions and requests. This is meant to get more people into the hobby, not for me to feel like I know everything or am superior/above reproach.

 

[Matias]

As soon as possible please post some inner shots. An organizer and tight assembly is a plus in my book.

I will. The moment I get the first order of cases in I'll be putting together both a six channel NC252 build (that will hopefully find its way to Amir in the future) and will have all the good shots. While I am trying to keep things simple and "cheap", I definitely know fit and finish and tidiness goes a long way.

Great to have another option in the US. Interested in your 8 channel NC252MP, I've been looking at the $1,899 VTV 8 channel or two of the $970 Audiophonics HPA-Q250NC. I'm good with XLR only but would prefer RCA as well as I will be using a Denon X6400H until I can go separates. How would you sell me on your amp? Thanks

Christmas has arrived early! The first batch of cases, the 17" wide 6-channel models, arrived today. They are even more well built/put together than I expected. Going to begin the first assembly, a 6 channel NC252MP amp for Lonestar and then post even more pictures.

Wouldn't it be possible to order RCA-XLR cables and use the the amp XLR only?

My selling point would be a low price for the exact same sound quality as other offerings

But really, that's my selling point. I am definitely still using quality parts and paying attention to detail, but since the NCxxxMP modules require no extra input buffers or add-ons that may or may not have a subjective difference, my goal is to offer amps that just work for low cost.

I understand if people have nice RCA cables already. If that is the case, the Emotiva RCA to XLR adapters for $8 work perfectly (and are wired correctly).

Good enough of an answer for me, just wanted to keep you on your toes! Non-stock input buffers/op-amps don't particularly interest me. Was planning to use the Neutrik NA2MPMF XLR to RCA, will have to check out the Emotiva. Glad to have run across this when I did, planning on making the purchase in the next 2-3 weeks. Would like to see a completed build inside and out for one of your amps, the 6 channel version would be fine if that is what you are building first. Also need a 4-5 channel purifi based amp...
