- Compact maar krachtig: de H7PRO beschikt over de TPA3255 digitale high-end klasse D-versterkerchip met een maximaal uitgangsvermogen van maximaal 300 W per kanaal, die moeiteloos 4-8 Ω-luidsprekers kan aansturen en een indrukwekkende geluidskwaliteit levert. Dankzij het compacte formaat is hij geschikt voor verschillende toepassingen, van boekenplanken en desktop-setups tot thuisbioscopen.
- Ontwerp met dubbele VU-meter en balansregelaar: Gebaseerd op de H7 en nadat we veel nuttig advies van onze gebruikers hebben ontvangen, is de H7PRO ontworpen met dubbele VU-meters voor het linker- en rechterkanaal, die dynamisch zwaaien met veranderingen in het audiosignaal. De onafhankelijke volumeregelaars van het linker- en rechterkanaal zijn verwijderd en de balansregelaar toegevoegd om het volume van de linker- en rechterluidsprekers aan te passen voor een egalere en natuurlijkere klank.
- Twee analoge ingangen en een voorversterkeruitgang: de H7PRO combineert een minimalistisch ontwerp met uitzonderlijke functies. Naast de standaard Cinch-ingang beschikt hij ook over een symmetrische XLR-ingang om storingen te minimaliseren en het basisgeluid te verminderen. H7PRO beschikt ook over een voorversterker-RCA-uitgang, waarop een andere versterker en actieve luidsprekers/subwoofer kunnen worden aangesloten om 2.1- of meerkanaals thuisbioscoopsystemen te bouwen.
- Componenten en geluid van audiofiele kwaliteit: de H7PRO maakt gebruik van Japanse ELNA- en Rubycon-filters, professionele audio-inductoren en verzegelde precisiepotentiometers, enz., met een SNR tot 110 dB en een extreem laag basisgeluid, om een uitzonderlijke helderheid en lage vervorming te leveren. Traditioneel design met voldoende warmteafvoer om optimale prestaties en een jarenlange stabiele werking te garanderen.
- Verfijnd vakmanschap en aantrekkelijk uiterlijk: CNC-gefreesde, aangepaste constructie van een aluminiumlegering die zowel duurzaamheid als een luxe uitstraling garandeert. VU-meter om het volume in realtime weer te geven, combineert retro-charme harmonieus met modern design, laat ons een HIFI muzikale reis door de tijd beleven met Douk Audio H7PRO.

Post Traumatic Slave Syndrome
Format: Hardcover
Very well done book that does not make Black People feel angry nor White People guilty but from a gentle and skillful psychological point of view the book will "have you considered the impact of this or that upon both races as the result of Slavery in America?" A folk-like homespun way of tell these truths that masks the clinical questions that all trained psychologist asked..."and how would (does) that make you feel for all of us who ever sat on a couch?" The book made me consider the psychological impact of daily slave life with a WOW again and again as I never thought of the situations the book made me consider. The shared dehumanization of both whites and blacks due to the slave experience which goes a long way towards explaining to me why we as a country cannot truly discuss slavery's impact today. I found it self-healing and very necessary for all, both black and white, but especially for the victims of the African Holocaust my terminology not hers. I thought Dr. Leary PhD, did an excellent job and a high school or even a 6 grader could read the material without difficulty.

Healing & Understanding
Format: Paperback
We are living in a slave master's land (was the Indians..). Hundreds of years of slavery, mental torture and degradation and then "freed." No therapy. No understanding, not even patience. To listen to Dr DeGruy's youtube videos was so enlightening to me. Sorrow, but understanding and then JOY. I didn't understand the anger, towards myself or others. Now, I can see where so much pain has come from. I can show compassion and love towards myself and others. Whatever programming I had, has been deleted--destroyed. I look back with pride, hurt, and know that I, myself, can heal. What a blessing this woman has brought us! Thank you Dr. Joy DeGruy!

Why do black people . . .
Format: Hardcover
I purchased this book because I had many questions I wanted answered. Most of them were questions of "Why?". My biggest question was why we as black people have so many unhealthy habits in how we treat each other.
As a young African American male who was raised by his mother in a predominantly white suburban area, I wanted to know why, when I encountered other black youth in more urban areas, they would tell me I "talk white." What is "talking white?" Basically, talking white means I was talking like I have an education. Why do so many members of the black community (those without an education) reject me for valuing education? Why is it that when one black person fidns a way out of the ghetto, it seems the whole neighborhood, church included, condems that person for leaving "his/her people" and wanting to live in the suburbs with the whites? Why don't we support one-another in this society that has always held us from achieving our full potential?
I wanted to learn why we seem to have no clue of who we are, and so many of us, young and old, strive to "prove" we are "black enough." So talking a certain way makes us black? Or is it eating certain foods that makes us "black"? Listening to only certain kinds of music? We lack a firm sense of cultural identity. We take rebellious pride in being at the bottom, and equate success with "whiteness." We denounce the achievements of any black person and ostracize him from the community. We work to pressure our own to stay at the bottom.
In this very interesting book, the author, Dr. Joy Degruy Leary, proposes a number of explanations for why the African American community has developed these and other unhealthy cultural habits. Leary examines this very real "crabs in the barrel" mentality, as well as many other self-destructive habits which plague the black community. Leary establishes a diagnoses, and calls it Post-Traumatic Slave Syndrome. Leary presents a very strong argument that the behaviors are all symptoms that have been passed down through the generations of African American people from the dawn of the trans-atlantic slave trade to today. Leary uses her own observations to support her theory of Post-Traumatic Slave Syndrome.
This book is a very thoughtful read. The reason I give this work only four stars is because I truly feel that Leary's argument would have been much more affirmed and effective if she had included a visual timeline to help the reader to better understand the timeframes and chain of events in history discussed in the book. The argument also would have been more effective if the author spent more time on each point. At times it seems she's just getting started before summarizing all that was just said and moving on. Scholarly sources are cited and research is used, but the book does not explore any one study or statistic in great depth. It is a fast read.

America's Biggest Lie
African Americans have been brutalized beyond imagination. Then told that they were the ones that were less than human. It boggles the mind. The whites beat, burned, skinned, lynched, mutilated and murdered African Americans at will. And these same whites believe (to this day) that this is their god given right. Even worst was the emotional and intellectual scars left from the lies that were told. If I didn't see the consequence of this everyday, I would think someone was lying to me: Some kind of Cosmic joke. The white criminals are the heroes and the African victims are the villains. This cannot actually be real. But it is. Whites stripped the Africans of their names, religions, dignity, culture and their humanity. Then called them less than human. This slight of hand is beyond comprehension. The funniest part is when I hear Whites yell to blacks "go back to Africa." This is tantamount to kidnapping someone, tying them up, putting them in your basement then yelling at them to get out of your house. Insane. This has been going on for 400 years. Wow. And America thinks it the moral leader of the free world. I have to pinch myself. This has to be a dream.... or a nightmare. The book opened my eyes.
