  • My Squeezebox Help
    My squeezebox help Continue SqueezeboxSqueezebox 3 in Logitech housingDeveloperLogitechTypeNetwork Music PlayerRelease date2001Introductory priceUS $199.99 (179.99)Discontinued2012 Squeezebox is a network music player from Logitech. The squeezebox was originally discontinued in favor of a visually similar but simplified Logitech UE Smart Radio, but in 2013 Logitech added an official menu option to install Squeezebox software on Smart Radio, effectively turning it into Squeezebox Radio. History Slim Devices was founded in 2000 and was first known for its SlimServer used for music streaming, but launched a hardware player called SliMP3, capable of playing these streams in 2001. Although the first player was fairly simple only supporting the Wired Ethernet and MP3 native, it was followed two years later by a slightly more advanced player that was renamed Squeezebox. Other versions followed, gradually adding support for additional file formats, Wi-Fi support, gradually adding larger and more advanced displays, as well as a user-focused version of audiophiles. Support for music playback from external streaming platforms such as Pandora, Napster, Last.fm and Sirius has also been added. Devices as a whole have two modes of operation; either autonomously, where the device connects to the Internet streaming service directly, or to a local computer running Logitech Media Server or a network storage device. Both server software and most of the firmware on the latest players are issued under open source licenses. In 2006, Slim Devices was acquired by Logitech for $20 million. Logitech continued to develop the player until it announced its discontinuation in August 2012. The online service mysqueezebox.com needed to use Squeezebox without a private server is still supported by Logitech.

  • The Outlaws' Guide to the Marantz AV7005
    The Outlaws’ Guide to ® the Marantz AV7005 Marantz AV7005 7.1 Channel Pre-amp/Processor Version 1.0 Marantz is a registered trademark of D&M Holdings Outlaw and cowboy logo are registered trademarks of Outlaw Audio, LLC The Outlaws’ Guide to the Marantz AV7005 Important – How To Use This Guide Thank you for purchasing the Marantz AV7005 surround sound processor. The AV7005 is a full-featured surround sound product that offers a wide array of features such as decoding for lossless audio formats, accurate video scaling, and automatic room correction technology. All of these provide great improvements in audio and video performance, increasing your enjoyment of music, television, and movies. However, these amazing technologies carry with them an inevitable side-effect: you have to set it all up and learn how to take advantage of the power and flexibility it offers before you can see and hear the full benefit of all of these new wonders. What The Outlaws’ Guide Won’t Do There are a number of details in the AV7005 User Guide that we have not reproduced in the Outlaws’ Guide. If you need to find out how to set tuner presets or program the remote control to operate other devices, please refer to the AV7005 User Guide. That guide also contains additional details on the network sources offered by the AV7005. What The Outlaws’ Guide Will Do That brings us to this guide. The Marantz AV7005 User Guide covers every bell, whistle, and sprocket under the AV7005’s hood, but we felt that a supporting document from an Outlaw perspective would benefit our customers.

  • Computadoras Electronicas
    COMPUTADORAS ELECTRONICAS Prólogo En la unidad 0 se hace una introducción, definiendo algunos conceptos previos. En la unidad 1 se muestran las diversas tecnologías en las que se fueron construyendo las computadoras. Luego se hace una breve revisión de los principios de circuitos digitales secuenciales y combinacionales, para comprender luego el Hardware principal de la computadora, como ser la Unidad Lógico Aritmética y la Unidad De Memoria. También se exponen las principales tecnologías de semiconductor con las que son construidas las computadoras actuales. Y se hace una descripción funcional de todas y cada una de las partes elementales de la computadora. Finalmente se describen los dos tipos básicos de arquitectura de computadoras ejemplificando cada uno. En la unidad 2 se hace un repaso de sistemas posicionales de numeración haciendo especial énfasis en el hexadecimal y binario. Además se desarrollan los diferentes códigos binarios con los que la maquina almacena y procesa la diversa información digital. En la unidad 3 se hace una integración de las unidades anteriores en la programación de un microcontrolador específico. Haciendo uso de un entorno de desarrollo integrado para tal fin. Utilizando el lenguaje Ensamblador ya que al ser de bajo nivel se puede tener una compresión mas profunda de lo que ocurre a nivel Hardware y poder relacionarlo con el Software. En la unidad 4 finalmente se expone el lenguaje C, luego de haber pasado por el Ensamblador se busca un mayor nivel de abstracción para poder resolver problemas de mayor complejidad. Este material se realizó con fines didácticos y se encuentra en proceso de desarrollo.
