Stereo-4
Stereo-4, also known as EV (from Electro-Voice) or EV-4, was a matrix 4-channel quadraphonic sound system developed in 1970 by Leonard Feldman and Jon Fixler. The system was heavily promoted by RadioShack stores in the United States, and some record companies released LP albums encoded in this format. It was the first commercial quadraphonic sound system for LP records. Development The original EV system was compatible with the Dynaquad DY system, and is related to Sansui's QS Regular Matrix system. The EV and QS records are very close to each other—it would take an expert to tell them apart by ear. EV decoders were sometimes used to produce pseudo 4-channel effects from 2-channel stereo recordings. In 1973 Electro-Voice signed an agreement with Columbia/ CBS Records to build a new ''universal'' decoder that could decode both SQ and EV records with good results. It could even decode QS records—again, with good results. EV later suggested the same coefficients for an en ...

Quadraphonic Sound
Quadraphonic (or quadrophonic, also called quadrasonic or by the neologism quadio formed by analogy with "stereo"">portmanteau.html" ;"title="/nowiki>portmanteau">formed by analogy with "stereo" sound – equivalent to what is now called 4.0 surround sound – uses four audio channels in which speakers are positioned at the four corners of a listening space. The system allows for the reproduction of sound signals that are (wholly or in part) independent of one another. Four channel quadraphonic surround sound can be used to recreate the highly realistic effect of a three-dimensional live concert hall experience in the home. It can also be used to enhance the listener experience beyond the directional limitations of ordinary two channel stereo sound. Quadraphonic audio was the earliest consumer product in surround sound. Since it was introduced to the public in the early 1970s many thousands of quadraphonic recordings have been made. Quadraphonic sound was a commercial failure ...

Dynaquad
Dynaquad, or DY, was a matrix decoder 4-channel quadraphonic sound system developed by Dynaco in 1969. The system originally had four speakers that were arranged in a diamond shape (centre-front, centre-left, centre-rear, centre-right). Initially (first available in 1969 with th ''Dynaco SCA-80Q'' amplifier ), it was introduced as a derived (2:2:4) four channel "decoding" system based on the Hafler circuit, where the back channels played ambient sounds recovered from standard stereo sounds. As such it wasn't used initially used as an encoding method (a similar approach was used on the Electrovoice Stereo-4 system). Commercial usage A simpler form of Dynaquad was adopted, allowing an easy adaptation of existing home setups. The two forward speakers remain in their normal positions, with the user only needing to add two similarly positioned back speakers, forming a square (front-left, front-right, back-left, back-right). Four channel record pioneers Vanguard Records started to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ovation Records
Ovation Records was an American independent record label based in Glenview, Illinois. The label was founded in 1969 by Dick Schory, who had been on RCA Records with his Percussion Pops Orchestra and had helped create the Dynagroove process used by RCA. The label was created to feature many different genres; the mid-1970s success of The Kendalls gave Ovation an image as a country music label, although it continued to record rock and pop. In the early to mid 1970s most Ovation LPs were released in a 4-channel matrix quadraphonic format, which was also compatible with conventional 2-channel stereo playback systems. The label initially used the EV or Stereo-4 matrix but later changed to QS Regular Matrix Quadraphonic Sound (originally called Quadphonic Synthesizer, and later incorrectly referred to as RM or Regular Matrix) was a phase amplitude Matrix decoder, matrix 4-channel quadraphonic sound system for phonograph records.

LP Record
The LP (from long playing or long play) is an Analog recording, analog sound storage medium, specifically a phonograph record format characterized by: a speed of revolutions per minute, rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire US record industry and, apart from a few relatively minor refinements and the important later addition of stereophonic sound in 1957, it remained the standard format for record albums during a period in popular music known as the album era. LP was originally a trademark of Columbia and competed against the smaller 7-inch sized Single (music), "45" or "single" format by RCA Victor, eventually ending up on top. Today in the vinyl revival era, a large majority of records are based on the LP format and hence the LP name continues to be in use ...
