Hypex NC400 Mono Block Amplifier - Unassembled DIY Kit
A while back I decided to build a proper power amplifier for my setup. I wanted it to be very good sound-wise, but also quite powerful since my speakers like a lot of power. Hypex recommends that the LMs used as buffers be powered by off-board high quality power supplies, so I decided to go that way.
It may appear to be a simple design, using only a handful of parts, but a look underneath the PCB tells a very different story:.
It is designed specifically for the UcD and is rated at W continuous output W short term. With all that in mind, I purchased a 2U aluminum chassis from modushop. I estimated the total consumption of the 3 LMs to be well under mA, so I went for a VA toroidal transformer with three separate center-tapped windings. Yeah, I know.. I designed the circuit and the PCB in Diptrace. Next up was the rear of the chassis. I think it turned out OK. Next up, I had to modify the modules since I wanted to use an outboard aux power supply.
That meant desoldering the power transistors that do most of the work:. Everything went according to plan, no magic smoke was released, so I proceeded to the final assembly. This was the end result:. Meanwhile, I had built a little power control board, seen above on the bottom left.
Nothing fancy, just a stand-by power supply, the necessary fuses and a couple of high current relays. That led me to think up of a new power control board:.
The timing of the relays was controlled by three timer ICs, set to monostable mode and each adjusted to a different time period. Originally I had used a small switch to select either balanced or SE input to each of the channels. That worked OK, but eventually I wanted to have remote control of the input selection, as well as a better overall solution. That led me to design a small PCB that would house a small signal relay and some control elements. I built three such PCBs and installed them in the amp:.
A logic low at the control pin selects the balanced input, a logic high the single ended. Pin 1 of the XLR socket should be connected to the chassis. They should be electrically isolated from the chassis. There are three pins. This exact method of grounding virtually guarantees no problems due to ground loops no humming etc.
My amps are dead quiet. I am looking into Hypex now and think a 3 channel system would be a good deal. How do yours sound? The Hypex amps are pretty great if you need a lot of power without sacrificing SQ. My center channel is also DIY, using Seas units. Pin 3 of the XLR socket should be connected to the chassis.
And thank you for your kind words. Your email address will not be published. This site uses Akismet to reduce spam. Learn how your comment data is processed. It would also have to be a 3 channel amp, driving my center channel as well as my main speakers. It may appear to be a simple design, using only a handful of parts, but a look underneath the PCB tells a very different story: So, it is not what you would call minimal.
But it is top-notch, technology-wise. All looked well so I proceeded to construct the LMs power supplies. That meant desoldering the power transistors that do most of the work: and soldering in lines to the aux power supply: Perfect! It was time for a test run: Everything went according to plan, no magic smoke was released, so I proceeded to the final assembly. This was the end result: Meanwhile, I had built a little power control board, seen above on the bottom left.
I built three such PCBs and installed them in the amp: I decided to include manual selection of input via toggle switches as well. The Bypass header is for connecting a switch to be used as manual selection between inputs. Share this: Twitter Facebook. Cool project, by the way.

Hypex Nc500 Review
Musical, dynamic, warm, and engaging with a very big soundstage and 3D sound. Hypex Electronics develops and manufactures amplifiers, supplies and DSP's with the highest possible quality in mind. My new Hypex NCMP based amplifier sounds so pure, timing is fine but no muscle on the bones during vocals, drums sounds like beating pots, sound is very detailed but instruments have flat character. This Amplifier in very good condition and been used intermittently since I've had it from new.
The amplifier is handbuilt with highest precision using only highest quality components. The input connectors are Neutriks high quality gold plated XLR sockets. The amplifier has a soft start function and it is turned on with an illuminated switch on the front panel. The amplifier also has a standy mode, to turn it off completly a high quality mains switch on the backpanel is used. The Sparkos Labs SS78 and SS79 Discrete Voltage regulators bring many advantages compared with standard monolithic designs where large capacitors for heavy filtering on the internal voltage can not be implemented. The fully discrete erorr amplifier on the device gives the ability for amazingly high input rejection and unique compensation techniques that are not possible to implement with regular monolithic IC error amplifiers.
Distortion at listening levels 1W is unmeasurable. Anyway, as-is the Hypex is the perfect partner for my EAR or GlowMaster power amps and delivers a firm, solid bass from my reference speakers. Free shipping. OEM pricing and custom design options available. The manufacturer Hypex itself sells a kit that contains an NC module, a W source and a box. Striking similarities between my scope measurements of the miniDSP amp. Price and form factor is very attractive, along with the fun of assembling the amps.
In Stock. Same Business Day Shipping. Domestic Orders Ship FedEx. The Hypex NC Mono Block provides an ultra high-end amplifier for a fraction of the price of comparable units.
That's funny opinion
Understandably, many thanks for your assistance on this matter.
I find that you are not right. I'm sure. I can prove it. Write in PM, we will discuss.
