In
response to many requests over the years since the release of Eric Bibb’s
breakthrough album "Spirit & The Blues " we are now pleased to
make this and also "Good Stuff " available on special 45 rpm double LP’s.
Since most
complete CD's are too long to be accommodated on a
regular LP (33 rpm) it was necessary to produce a double
LP, which in turn meant that advantage could be taken of
the use of 45rpm. The main advantages of this is that it is possible to increase the cutting level thus reducing,
in relative terms, the noise of the record. In addition the
increased speed of rotation of the record gives improved high-frequency
performance which is of particularly significance
especially in the later parts of the record as the
circumference progressively reduces.
We
would also like to draw attention to the following:
A cutting lathe requires two signals, one feeding the
cutter head and the other which gives information in
advance to enable the grooves to be packed in the best
possible way without impinging on adjacent grooves.
For this purpose a special tape recorder is required
with one "preview" head for the spacing of the
grooves and one audio head which feeds the cutter.
Between
the heads the tape makes a special loop which provides the required delay.
Because these very special tape recorders are becoming increasingly rare, many
cutting studios have resorted to incorporating a digital delay in the signal
path in order to use an ordinary tape recorder. This means that the audio
signal in the record-groove has first been A / D converted, i.e. digitalized,
then digitally delayed then D/A converted back to analogue. Such a vinyl
record is therefore not truly analogue. Needless to say all Opus3 LP’s, are
of course mastered in the old authentic way and are thus analogue all the way. |
