You cant afford to miss a single day. So check it out at www. Our purpose was to design and construct a complete do-it-yourself audio system. After many conversations about the affordable architectures and power re-quests, we ended up choosing two un-common amplifiers: A and the Hypex UcD Audioxpdess latter is a class D amplifier from the Dutch company Hypex www.


The UcD is to be covered in the second part of this article. In this two-part article, the authors present two amplifiers capable of satisfying many users power needs. Ideally mated with high efficiency, 34 mm dome Audax tweeter with JA-waveguide. Where other coils get overheated, youjust order Jantzen C-Coils. Designed for bass, subwoofers andamplifiers.

Absolutely the closest to the idealinductor in the World. Hard as a rock. New round wire coil made of 1. Available as air cored coil and with non-ferrite core.

Superior Cap Even the finestnuances can be heard. The sound never gets over-edged,really superb naturalness witha somewhat bright top-end. Silver Cap Super smooth cap withoutany harsh additions to the sound.

Absolutely neutral tonal apil. A truly outstanding audio part. Silver Gold Cap More resolution,more sound stage.

Fast reaction, life feeling and natural sound. The in-terest aroused by the My Ref. With the thread counts to-taling more than pages.

Figures 1 and 2 show, respectively, the amplification circuit and the power supply with a speaker protection sec-tion.

From the schematic you notice that the My Ref. These are all uncommon features in modern audio amplifiers. Moreover, the Italian design-er of this project has studied Graham Maynards reverse-driven measurements Maynard published various articles on this subject in the magazine EW, be-tween By this test, you can see the DUT damping factor amplitude and phase changes in the audio spectrum. Both Maynard and Penasa found a correlation between the reverse-driven measure-ment and the sonic result.

Their con-clusion was that an amplifier with an almost flat damping factor amplitude, as well as a phase without big rotations, ensures a clean and balanced sound.


If you are interested in the topic, you can read more about it on Mauros home page: There wouldnt be that much interest from the DIY community if this projects musicality or electronic circuit were lacking.

This article uses the first revision A. In this version Pe-nasa wanted to reproduce the sound of a single-stage class A amplifier, such as the JLH 10W or the Aleph, while the rev.

C is a different amplifier rather than an upgrade from rev. You can switch from one revision to the other just by substituting a few components, using the same PCB Figs. As you can see, we used a single face Eurocard.

He suggests that, to make the PCB, you use 70m 2 oz. This PCB has all on board, so you just need to add a cabinet, a transform-er, a switch, and a main fuse to get it ready to rock.
