ORTHOPHONIC TALKING
MACHINE REVELATION

A new era in the mechanical re-
production of sound was heralded last
night with the demonstration here Of
the newly invented Orthophonic talk
ing machine, whose announcement has
created a sensation in musical circles.
This instrument, which is declared to
represent q 100 per cent increase OF
efficiency over the old type, was ex-
hibited to a distinguished group of
musicians, critics, and prominent citi-
zens at special advance hearing in
San Antonio arranged by Thomas
Goggan and Bros, Victor dealer, as n
preliminary to the general public hear
ing next Monday evening.
The remarkable advance represented
by the new instrument, which was
developed Jointly by the Victor Talk
ing Machine Company and the Bell
laboratories of the Western Electric
Company, was illustrated by playing
it in direct comparison with the old
type. The audience applauded as Sc
lection after selection bore witness to
the greatly increased range, volume,
and purity of tone achieved by the
new method.
HAS NEW PRINCIPLE.
The Orthophonic talking machine is
based upon newly adapted principle
known as matched impedance," which
has necessitated the complete re-de-
signing of the entire instrument. This
electrical principle, which made pos
sible the perfection of long-distance
telcphonis communication, was trans
lated into mechanical terms BY the
Bell laboratories Of the Western Elec-
trio Company and placed at the dis
posal of the Victor Company. 1t has
resulted in an increase of range, be-
sides doubling the potential volume OF
the reproduction and the clearness
with which the various instruments
and voices may be distinguished.
While the exterior of the instru-
ment has undergone no fundamental
change, the interior is altogether diff.
ferent. One of the striking features
of the new equipment is great horn,
six feet in length, which is ingenious
ly folded and out Of sight within The
body Of the cabinet. Above it is the
usual record turntablc and tone-arm,
the latter of new and improved con-
struction. The Eound box is COM
pletely changed, unique diaphram
of duralumin being substituted for the
old mica disc.
MADE BY MATHEMATICS.
"The entire instrument, from needle
to horn opening, has been carefully
designed, according to mathematical
formula based upon the principle oil
matched impedance," said Mr.. Ko.-
oskey, who conducted the dcmonstra-
ton. "Thus, by perfect coordination
of the various working parts, it has
been made possible to take the sound
impulses from the needle and to con-
duct them smoothly and without dis
tortion into the air. The result Is
music undiluted and undefiled."
Mr.. Thomas Goggan explained that
heretofore there have been three chief
defects in the talking machine-lim'
tied range, limited volume and failure
to bring out clearly the tone color OF
the sounds recorded, that indefinable
quality by which it is possible to dis
tinguish between the various instrl-
ments. or voices even when playing
notes of the same pitch.
COVERS ALL SOUNDS.
~These difficulties. he continu ID.
shave now been removed. The Ortho-
phonic Talking Machine is capable Of
reproducing sounds as high rs tho
highest note Of the piccolo, or as low as
the deepest tone on the bass VOL.
1t can reproduce these soft as whis-
per, or as loud as a shout. And it can
reproduce them in such way that you
can readily identify the notes of the
violin, the cornet, the flute and every
other variety of instrument or voice.
"One of the greatest achievements
of the new method" he said, sis the
successful reproduction of instrn
