A history of stereo records in living monophonic sound!

I like how RCA tries to make it their innovation, when in fact it was Westrex who developed the stereo cutting head and Audio Fidelity released the first stereo LP in 1958 (before there was a stereo compliant cartridge available to play it).

Peter Nawalan Actually stereo was used in movie soundtracks, 2 tracks, one for your low to mid range frequency and the other mid to high frequency. Then it on the projected it was actually read by an optical pickup!

Very interesting document of the revolution of how listened the music.

hehe the arm on that groove grinder! the headshell looked like it was tracking at about 10grams..but it probably still sounded better than a Crossley.

So cool!! Even if Westrex was the actual innovator who designed this type of stereo cutter.

In typical marketing fashion, the speaker (from the marketing department) treats stereo LPs as an "exclusive" product of RCA, implying that they invented it and are sole marketers. Actually, Westrex invented the stereo (and mono) disk-cutting system and made it available to all record companies. Also, remember that Columbia, RCA's biggest competitor, had invented the 12" 33 rpm long-play record, which RCA resisted by attempting to market 45 rpm as the standard. It is amusing to see RCA showing off the same 12" records that Columbia had invented!

the first stereo was either left channels or right. eventually they could shift the phase so sound could move from left to right. pink Floyd era

Tangobaldy In 1958 Silvania produced the portable 3 channel speaker phonograph called the "Golden Shield". If something moved from one side to the other it was very apparent tho few artist of the day used this sort of effect.

2:44 ceramic bar. tsk tsk tsk tsk. Magnetic cartridges were not developed yet. Well, the records were pressed with a harder vinyl to compensate for this.

That guys is hot !!
