Hi, I built 2 hypex UcDHG w/HxR monoblocks about 4 or 5 years ago. At that point the switch mode PSU had not been introduced, so I used. Module amplificateur Hypex UCDHG HxR W . Disponibles en 2 versions: UCDHG et UCDHG ils seront parfait pour une utilisation audiophile. Logo AA 0 The UcDHG amplifier module is a self-contained high- performance class D amplifier intended for a wide range of audio applications.

That meant desoldering the power transistors that do most of the work:. Next up, I had to modify the modules since I wanted to use an outboard aux power supply. I designed the circuit and the PCB in Diptrace. Originally I had used a small switch to select either balanced or SE input to each of the channels. Description The UcDHG amplifier module is a self-contained high-performance class D amplifier intended for a wide range of audio applications, ranging from Public Address systems to ultrahigh-fidelity replay systems for studio and home use.

My amps are dead quiet. However, this suits me quite nicely and I’ll leave it there. I decided to go a little further aiming at wpc and the Hypex modules seems ideal for this. My ordering list was this: Close Accept and continue.

A power amp doing wpc can these days be had for almost nothing, e. A short while later I was done: Cool project, by the way.

And thank you for your kind words. Next up was the rear of the chassis. Customers who bought this product also bought: Anyway, as-is the Hypex is the perfect partner for my GlowMaster and hyypex a hypx, solid bass from my stock ATS-4 and Illuminator-5 speakers.

Sorry, your blog cannot share posts by email. Learn how your comment data is processed. There are three pins. I decided to include manual selection of input via toggle switches as well.

What matters is its ability to deliver some amperes.

This information has been provided to you free of charge for your use but remains the sole property of Hypex Electronics B. This is so cheap we could use the chassis and heat sinks alone and mount our own modules in case we have better ideas. Be patient during sending That meant desoldering the power transistors that do most of the work: My resistor choice to make max -5 dB gain did not exactly turn out the way I wanted.

I bought a VA toroidal transformer locally plus a small 2 x 15 volt transformer also needed for the UcD module, which I wasn’t aware of at the time I ordered the kit. By buying this product you get 14 loyalty points.

It would also have to be a 3 channel amp, driving my center channel as well as my main speakers. Control is based on a phase-shift controlled self-oscillating loop taking feedback only at the speaker output.


The timing of the ucd400ug was controlled by three timer ICs, set to monostable mode and uypex adjusted to a different time period. More from Wikipedia on the phenomenon here. This exact method of grounding virually guarantees no problems due to ground loops no humming etc.

A while back I decided to build a proper power amplifier for my setup. Above the actual measurements displaying the reduction in gain for the 5 stages. The rest I bought locally.

That led me to think up of a new power control board: I think it turned out OK. It was time for a test run: Chief distinguishing features are flat frequency response irrespective of load impedance, nearly frequency-independent distortion behaviour and very low radiated and conducted EMI.

With all that in mind, I purchased a 2U aluminum chassis from modushop. So, it is not what you would call minimal. You can download the full schematics and PCB here: Ready made circuit boards, and all you need is a chassis and a bunch of wires. Pop-free start and stop control Differential audio input Overcurrent and over voltage protection No compromise components LM buffer OpAmp HxR12 ready Improved on-board buffer supply.

I am looking into Hypex now and think a 3 channel system would be a uc400hg deal. This was the end result:. We deliver all of France, and internationally.
