In every test and critical application, Magnecorders
prove themselves far and away the finest professional
tape recorders available. That explains why Magnecorder is the most widely used professional tape
recorder in the world-used by more engineers and
broadcasters than all others combined. Only Magnecorder provides such flexibility and performance for
a minimum investment.
Applications are endless . Whether it is recording
vibration data and electronics phenomena for ,ndustry , or spoken words and musical sounds for
schools and broadcast stations, the precision-engineered Magnecorder delivers a full-range frequency
response and unwavering accuracy that meet the
high e st standards ever set for recording . Magnecorder's exclusive unit construction permits easy combining of units for every specia!" requirement.
With a Magnecorder working for you , the sound is
recorded exactly as you heard it. The acfual fe sf on
the engineering floo r is preserved for permanent
refere nce. The living voices around the confe rence
table are captured with every cough and intonation
flawlessly intact. The recorded symphony goes on
the air without the slightest audible loss of "live'! quality. Wherever recordings are made, we invite you to
compare the Magnecorder for product, performance
and price. Prove to yourself that Magnecorder has
more to offer you than any other professional recording instrument!

THE FIRST ONE-CASE
PROFESSIONAL TAPE RECORDER
The new Mag.neco rd Voyager PT6-VA H is a single-case
portable recorder designed to lighten all remote recording chores. Built for rugged serv ice in the field, it combines new convenience at no sacrifice of durability and
strength. like all Magnecord units, the Voyager retains
the superb quality that has ",!ade Magnecord the most
widely used of professional tape recorders around
the world.
In design, the Voyag'e r consists of the basic PT6-AH
tape transport, hinged back-to-back with a new recor d/
ployback amplifier with dual equalizer for both l V2 '
and 15- tape speeds. The amplifier swings up into position on top of the recorder unit at a moment's notice,
or slides free for side-by-side operation. Interconnecting cables are permanently plugged in for instant set-up .

THE NEW
FOR 3-DIMENSIONAL
TAPE RECORDINGS OF STARTLING REALISM
like stereo-photography, 3-dimensional tape recording odds depth
and direction to sound. permitting you to hear the sound "all around
you", or isolate one sound from .the rest. The Mognecord Binaural
listens "with two ears", achieving th e most startling realism yet possible by a recording process.
Binaural , sound is fed by two low impedance microphones into the
PT6-BN amplifier. Channels are amplified separately and recorded
simultaneously with dual holf-track Binourol · heads on standard 14magnetic tape . "Binourol" playbacks employ the Binoural amplifier
plus earphones or two converging speakers.
For recording music, Binaural achieves "natural" reproduction of a
degree never before available, virtually duplicating the original performance for instructional purposes or greater listener en joyment.
As a reseorch tool for industry, the Binaural system can be used either
for 3-dimensional sound studies or for any purpose where duol chon·
nels are useful in reco rding synchronous functions. Also, the test can
be recorded on one track, with a spoken commentary or 0 tim e signal
on the other.
