Hva er Phase 4 Stereo? (Vinyl, LP)

[WayAhead]

Var innom godtebutikken igjen (Fretex) og det gikk som det pleier

men fikk med meg denne:

På baksiden står det: "These Stereo records can be played on mono reproducers provided either compatible or stereo cartridge wired for mono is fitted. Recent equipment may already be fitted with a suitable cartridge.If in doubt contact your dealer."
Hørtes så spennende ut at jeg bare måtte ha den....

Skiva er laget i ´74 eller noe og det var vel ikke rocket science å spille av stereoplater om så på mono utstyr den gangen heller?

ok, Googlet Wiki og fant det der:

Phase 4 Stereo was a recording process created by the U.K. Decca Records label in 1961.[1] The process was used on U.K. Decca recordings and also those of its American subsidiary London Records during the 1960s.

Phase 4 Stereo recordings were created with an innovative 10-channel, and later 20-channel, "recording console"[2] (actually a mixing console.) The concept of Phase 4 Stereo has no connection with Quadraphonic sound or "four channel stereo." But because there often are sounds out of phase, the records may also give pleasing results when played on Hafler circuit systems or other simulated four channel systems.

Approximately two hundred albums were released with the process, including popular music, "gimmick" records engineered to make the sound travel from speaker to speaker, records featuring percussion effects, and historical sound effect records. In 1964, a light classical Phase 4 "Concert Series" was produced.

In 1996 a CD, The Phase 4 Experience, was released with recordings from 1966 to 1979 (London 444 788-2 LPX/PY 871).

A space themed version, An Astromusical Odyssey, was arranged by Johnny Keating which included songs from the late 1960s to the early 1970s. A selection can be heard on YouTube.

Phase 4 - Stereo Concert Series: Recording and Mixing Demonstration

A JOURNEY INTO PHASE 4 STEREO SOUND 1965:

 

[Audiophile-Arve]

Phase 4 var også ein underlabel av Decca, som laga klassisk musikk med høg opptakskvalitet. (Har nokre fine sjølv)

Skal ikke se helt bort fra at det kanskje er Decca (og ikke RIAA) eq på den plata

DECCA var i hvertfall veldig aktive på mangr områder mht innspillingsteknikk osv. Det står også ffss på platen. mer om det og Phase4 her:

Stereo (ffss)[edit]
The British Decca recording engineers Arthur Haddy, Roy Wallace and Kenneth Wilkinson developed in 1954 the famous Decca tree, a stereo microphone recording system for big orchestras.

Decca started the first actual stereophonic recording 13–28 May 1954, at Victoria Hall, Geneva, the first European record company to do so; only two months before, RCA Victor had begun the first actual stereophonic recording in the U.S., 6–8 March 1954. Decca archives show that Ernest Ansermet and the Orchestre de la Suisse Romande recorded Antar by Nikolai Rimsky-Korsakov (Decca's official first actual stereo recording); Stenka Razin by Alexander Glazunov; Tamara by Mily Balakirev; Anatoly Liadov's Baba-Yaga, Eight Russian Folksongs, Kikimora; and Le Martyre de saint Sébastien by Claude Debussy. These performances were initially issued only in monaural sound; and in 1959, the stereo version of Le Martyre de saint Sébastien was issued only in the U.S. as London OSA 1104 (OS 25108); and stereo versions of others were finally issued from the late 1960s to the beginning of the 1970s as part of the ""Decca Eclipse"" series (in the U.K.) or "Stereo Treasury" series (in the U.S. on the London label).[30]

The Decca stereo format was called (in succession to ffrr) "ffss", i.e. "full frequency stereophonic sound". With most competitors not using stereo until 1957, the new technique was a distinctive feature of Decca's. Even after stereo became standard and into the 1970s, Decca boasted a special, spectacular sound quality, characterised by aggressive use of the highest and lowest frequencies, daring use of tape saturation and out-of-phase sound to convey a lively and impactful hall ambiance, plus considerable bar-to-bar rebalancing by the recording staff of orchestral voices, known as "spotlighting". In the 1960s and 1970s, the company developed its "Phase 4" process which produced even greater sonic impact through even more interventionist engineering techniques. Big-band leader Ted Heath was an early pioneer of the Decca "Phase 4" sound. Decca recorded some quadrophonic masters that were released in Sansui's quadraphonic system called QS Regular Matrix.

ffss tester som egentlig ikkr forteller stort men det ser ut til at DECCA også produserte "myteomspunne" pickuper.
Platen ble åpenbart kjøpt på steen & StrømOSL i sin tid. (price tag)

Jo, men den artikkelen du likner til omhandler ikke det.
Tabellen her sier noe om forskjellene:

Og - enkelte Phono-trinn har valgbar EQ-kurve:

Ja da er det er sikkert riktig det. Et sted jeg var innom stod det vel at DECCA generelt "boosted" topp og bunn? på sine innspillinger for denne perioden.

Forøvrig likte jeg aldri DECCA (Stones mfl) innspillinger. De låt "blikkboks" på utstyret de ble spilt på (70 tallet eller deromkring) Tenkte at DECCA måtte være tysk... HaHa...

Decca er en gigant - både musikalsk og lydmessig. Finner en original stereoeoplate med seriøs klassisk musikk, kanskje 40 til 60 år gammel, har du gjort et varp!!! Finner du i tillegg navn som f.eks. Kenneth Wilson og Kingsway Hall på baksiden av coveret - så skal du vite at du er på Mount Everest når det gjelder til naturlig lyd.
Decca pick-up'er er snadder. Har sine sider, men er på flere måter omtrent uovertrufne.
