RE: arsclist Re: Elgar and Menuhin

["Copeland, Peter" <Peter.Copeland@xxxxx>]

In answering *this* question, I am pleased to acknowledge the help of Steve
Smolian. He gave me a Victor frequency test disk some years ago (dated
"about 1932"), and this clearly documents RCA's extension of the original
Western Electric performance. I suspect (although I have no objective
evidence) that the response above 5.5kHz (the "official" Western Electric
limit) was equalised to bring it flat (or nearly so). It is only -4dB at
10.5kHz. The constant-amplitude turnover was raised in frequency, from 250Hz
(WE) to between 500 and 600Hz (about 250 microseconds), and this
characteristic was also used for Victor's 33rpm long-playing records. The
"diamond" evidently indicates this.  Peter

During a recent visit to Hayes I discovered an internal memo, I assume from
the pressing factory (initials are WSP) to the Artistes' department dated
24th May 1934.  And I quote:

"Each recording will also have a suffix, either a triangle, a square or a
diamond, which will indicate Western Electric, Moving Coil or Victor
recording system respectively, and this is also the same as formerly."

This does seem to back up footnote 3, p 174 of Elgar on Record.  But does
raise the question, what was the Victor recording system?  One assumes that
it refers to the acoustical process devised by Berliner.
