"Magic Brain" Record Changer and
Magic Tone Cell Win Favor
Since its introduction at the recent
music convention in New York the RCA
Victor's new type of automatic record
changer which plays both sides of the
record without turning it over, directed by
an uncanny "magic brain" has been
hailed by all who have seen it as a re-
markable step forward
in turntable
achievement. Incorporated into the new
Victrola combinations, the magic brain
eliminates old-style needles, extends
record life indefinitely and sets a new
standard in tone quality, according to
Allan B. Mills, RCA Victrola sales man-
ager.
Mr. Mills said that among the other
new features of the device are the Magic
Tone Cell (the pickup cartridge), the
Flexible Tone Bridge and the Jewel-Lite
Scanner. The new RCA Victrola equipped
•with these innovations and the Tandem
Tone Arm will play both sides of 15
records without attention once a starter
button has been pressed.
"The Magic Brain" he said, "provides
demonstrable features on which RCA
Victrola dealers can capitalize more than
they have ever been able to do before.
Automatic home entertainment, both
phonograph and radio, of a quality never
attained commercially before is now a
reality."
To operate a Magic Brain record player
equipped with the Tandem Tone Arm it is
only necessary to stack the records on
the automatic mechanism and press the
starting button. The Tandem Tone Arm,
which is actually two arms and tvo pick-
ups (one for playing the top oi a record
and the other for reproducing the lower
side) shaped somewhat like a tuning
fork, swings over and plays the top side
of the bottom record of the stack which
has been dropped to the turntable. After
reaching the end of the record, the Tan-
dem Tone Arm swings clear of the record
while the direction of the turntable's
revolution is reversed. Then it rises far
enough to make contact with the bottom
side of the record.
When the under side has been played,
the Tandem Tone Arm swings away so
that the record may be deposited gently
into a felt lined compartment, after which
another record from the bottom of the
stack drops into place. The cycle is re-
peated until all the records have been
played. The Magic Brain then automa-
tically shuts off the mechanism.
THE MAGIC TONE CELL
Secret of the remarkable tone quality
achieved with the new instrument is the
Magic Tone Cell, which is an important
Controls of the Magic Brain are ex-
ceedingly simple. The large lever
above the hand in the picture adjusts
the mechanism for playing either one
or both sides of the records. A record
may be rejected while playing by
pushing the starting button. An on-off
switch is the only other control on the
panel. To adjust the drop mechanism
to 10 or 12-inch records, it is only
necessary to turn the support shown
to the far left.
part of each tone arm. The cell is made
up of the Flexible Tone Bridge and the
Jewel-Lite Scanner. The former is a fine
wire filament scientifically designed to
eliminate at the source all objectionable
needle chatter. The scanner is a carefully
ground sapphire point which replaces the
needle. The perfectly balanced Magic
Tone Cell exerts a minimum of pressure
on the record which, combined with per-
fect tracking, assure indefinite life for the
sapphire point and the records and avoids
chatter. Gruelling laboratoy tests, running
into many hundreds of hours, have in-
dicated the life-span of the Scanner and
Bridge to be far beyond the heaviest
demands imaginable.
"With the phonograph compartment
open the 'Jewel-Lite Scanner' running in
the record groove without amplification,
the Magic Tone Cell creates substantially
less sound from mechanical vibration
than the sound which escaped past the
very effective Tone Guard in last year's
instruments," Mr. Mills said.
The vibrating parts of the Magic Tone
Cell, Mr. Mills said, weigh less than a
postage stamp despite their effectiveness
and rugged construction. The Magic Tone
Cell exerts approximately one-half the
pressure on the record of ordinary pickup
mechanisms, and there is no vlifference
in the pressure regardless of whether the
top or the bottom of the record is being
played.
The Magic Brain has been incorporated
in the 1942 Victrola Model V-225. Housed
in a Chippendale style cabinet with the
Magic Brain and all controls available
from the front, the instrument incorporates
a highly efficient chassis with 12 watts
of output through a push-pull audio sys-
tem. The new RCA Victor Teletube for
increased sentitivity. All other radio fea-
tures are of the most advanced design.
THE ROLL OUT "MAGIC BRAIN"
The complete Magic Brain mechanism,
with the exception that it has only one
Tone Arm and plays only one side of a
record automatically, is employed in an-
other new RCA Victrola automatic record
changer which introduces a new feature
achieving a new high in operating con-
venience for an automatic phonograph.
"This is known as the RCA Victrola
Roll-Out Magic Brain," Mr. Mills said.
"The whole automatic record changing
mechanism rolls out of the phonograph
compartment when the front is opened.
At just the right height for convenient
use, this automatic mechanism requires
but the stacking of records on the sup-
porting posts, a gentle touch to return it
to the compartment, and a press of the
starter lever. The cabinet may then be
closed for an automatic record concert
of about three-quarters of an hour. When
the last record has been played, the
mechanism is automatically shut off."
The Magic Brain Roll-Out mechanism is
featured in the 1942 RCA Victrola V-215,
a 9-tube instrument in an attractively
styled cabinet.
Another Magic Brain RCA Victrola
housed in k delightful Sheraton cabinet
is available as Model V-219. A split top
lid provides ready access to the auto-
matic mechanism and all radio controls.
Three low-price RCA Victrola console
models incorporating a completely new
automatic record changer are also in-
cluded in the series.
