Thanks also to my loving parents, who have always been there for me. The Early Years of the Acoustic Phonograph Its developmental origins and fall from favor 1877-1929 "Mary had a little lamb, its fleece was white as snov^. And everywhere that Mary went, the lamb was sure to go." With the recitation of a child's nursery rhyme, thirty-year- old Thomas Alva Edison ushered in a bright new age--the age of recorded sound. Edison's successful reproduction and recording of the human voice was the end result of countless hours of work on his part and represented the culmination of mankind's attempts, over thousands of years, to capture and reproduce the sounds and rhythms of his own vocal utterances as well as those of his environment. Although the industry that Edison spawned continues to this day, the phonograph is much changed, and little resembles the simple acoustical marvel that Edison created.

    Lynn Olson: a Tiny History of High Fidelity

    A Tiny History of High Fidelity, Part 1 A Rainy Night in Portland, 1936. Thanks to the restoration movement, much of downtown Portland still looks like this. Where do I come from? Where am I going? Who am I? These ancient questions are with us still. With only the slightest of changes, they can be recast into a form that provides a guidepost to the music lover, the audiophile, the hobbyist, and the artisan-engineer. Where does the art of sound reproduction come from? Where is it going? What do I seek from this art? Radio! 1900-1930 In the first years of Electrical Amplification, engineers had their hands full just trying to master the complex and non-intuitive mathematics of vacuum tube amplifiers and oscillators. It is worth keeping in mind that vacuum tubes were electronics in the first half of the Twentieth Century; before Lee DeForest modified Edison's light-bulb, the only form of "amplification" were relays that could repeat and rebuild telegraph signals. Radio relied on tuned circuits, massive brute-force spark-gap transmitters, large long-wave antennas, and crystal-diode rectification that directly powered the headphones. The faint signal that wiggled the headset diaphragm was a infinitesimal fraction of the megawatts that poured in all directions from the transmitter. Records, of course, were purely mechanical and acoustic, and wouldn't work at all if it weren't for horn-gain in recording and playback. What we now think of as electronic engineering back then was electrical engineering, focussed on keeping AC power transmission systems in phase and specialized techniques for pushing a telephone-audio signal down hundreds of miles of wire without benefit of amplification.

    Alan Dower Blumlein Of the men who were responsible for the development of the Marconi-EMI high-definition television system in the early 1930s, the name of Alan Dower Blumlein stands out.

    Redd Microphone Redd Microphone

    REDD MICROPHONE REDD MICROPHONE Continuing in the rich tradition of innovation at EMI, dating back to the early 1930s with Alan Blumlein, the father of ‘Stereo’, the company’s first coil microphones, velocity ‘ribbon’ mics and the “Blumlein pair” technique, Chandler Limited and Abbey Road Stu- dios introduce the first new EMI badged microphone in over a half century, the ‘REDD Microphone’. While the aesthetic is unmistakably classic, an ode to a gilded age of audio, the REDD Microphone is not a U-Type clone, it stands apart and on its own. The patent pending REDD Microphone is a large diaphragm tube condenser microphone, combining mic and preamplifier into the microphone body. Featuring the vacuum tube based REDD.47 Mic Amplifier circuit coupled directly to a custom handmade premium platinum membrane capsule, the REDD Microphone can be used with or without an external preamp. The proximity of the REDD Microphone’s custom capsule to its internal REDD.47 mic preamp circuit, creates the shortest possible path between the two most important elements in the recording chain, delivering a larger than life full-bodied sound, with a silky smooth top-end. Features available from the microphone body, include: 9 gain selections, +4 to +33db in ‘NORM’, extended gain and punch in ‘DRIVE’, Cardioid/Omni patterns, 10db Pad, and Phase. Continu- ous output control and low-contour voicing features are accessible from the high-quality external power supply. HISTORY In 1958, EMI and Abbey Road Studios, through their REDD (Re- cord Engineering Development Department) technical division, designed the REDD.47 line amplifier as a plug-in line amplifier for their new REDD.51 consoles, replacing the Telefunken/Siemens V72s used in early REDD mixing consoles.
