… of high fidelity, or so Columbia Records claims, circa: 1956. At a time when many lesser-than labels were pushing “high fidelity” as more of a general, blanket statement rather than something that could necessarily be guaranteed, Columbia felt the incessant urge to mark themselves above all others with their “360” SOUND symbol. Have a read below from the majestic wonders of “360” SOUND, in Columbia’s own words (as found on the back of Paul Weston and His Music from Hollywood’s Moonlight Becomes You):
The symbol “360” SOUND is the summa cum laude of high fidelity.
It is your GUARANTEE that each record so designated has been engineered and individually tested under the supervision of the Columbia Sound Laboratory.
Starting with the taping of the performance, through strategically placed wide-range microphones, every step in the manufacturing process is checked for peak efficiency — including an actual laboratory-calibrated playback of each disc before it is released.
Not only original masters, but stamper test-pressings are required to match, in A-B tests, the tapes from which they were derived.
Only such rigid control permits production of recordings covering the entire 30 to 15,000 cycle range within a plus or minus 2-decibel tolerance.
Like the 360 degrees of a perfect circle, “360” SOUND is the true spectrum of high fidelity.
For this reason Columbia Records, the oldest name in recording and creator of “Lp”, GUARANTEES without reservation the fidelity of this “360” SOUND record.
