Presenting the eo¥~ · LINE PROFESSIONAL FULL-RANGE SOUND REPRODUCTION ..,• ." I - 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! - - fflEOUEHGY IN C\'CI..ES PER SECOJoN) :ox~ 15 ~ tope speed-f lat from 50-15000 cps, j; 2 d b . 71k- tape speed - flo t from 50-7500 cps, :t2 db. 32f. - tope speed-flat from 504 000 cps, 2: 2 d b.

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. o Q) o ..
