The 33rd Audio Engineering Society Convention in New York City was a smashing success. A large variety of technical papers were presented by their authors (see AUDIO, October 1967), with audience participation spicing discussions.
The exhibit of professional audio equipment, with over 35 manufacturers displaying their technical wares, garnered favorable comments from attendees. Aside from the interest generated by new products, exhibit booths 'were manned by truly knowledgeable representatives who did a splendid job fielding questions on products and applications.
A number of exciting developments were shown at the exhibit. For example, Dolby Laboratories had a separate listening room where attendees were treated to playback of recorded tapes before and after they were "Dolbyized." Next door, Gotham Audio featured a great many new products, including: Neumann FET transistor microphones, an FM stereo monitoring receiver, miniature integrated amplifier/ speaker system for monitoring purposes, and a direct-reading audio wattmeter.
-------- Electro-Voice displayed its line of professional microphones as
well as hi-fi stereo electronic components. Altec Lansing spotlighted a control
console, "Voice of the Theatre" speaker
systems, and other professional sound equipment. Sennheiser exhibited its
complete line of microphones and other transducers.
---------- Electrodyne featured its audio control console. Gotham Audio's demonstrations
of operating equipment attracted considerable attention. The company's EMT
930 Studio Turntable System is shown in the background. Dr. Neumann (left)
and Stephen Temmer, president of Gotham Audio, are shown in inset.
Among other interesting developments shown at the AES show were: Altec Lansing's solid-state condenser microphone system; Ampex' 24-track, 1-in. tape recorder; Bozak's line of commercial amplifiers; Capps' models of styli, 50X normal size; Computron's (BASF) impressive display of different magnetic tape formulations; Crown's new computer logic control tape transport; Gauss' 120 ips (who says tape speed is getting slower?) tape machine for duplicating purposes; Electro-Voice's long line of microphones, including "shotgun" types; Fairchild Recording's thin-line series of speech input equipment; Lang's custom studio equipment; Nagra's miniature, portable, battery-operated tape recorders; Norelco's line of AKG microphones; Nortronic's broad line of magnetic tape recorder heads; Phase III's electronic music equipment, with Robert Moog showing 'em how; Scully's new professional tape recorders; Sennheiser's wall of mikes of various types; 3M's "Isoloop" tape machine, as well as its magnetic recording tape and "tape-on" speaker wiring system; Universal Audio debuted its battery-operated, three frequency test generator; Vega exhibited its wireless microphone system.
Shown here are some exhibit scenes captured at the show.
------- Dr. Ray Dolby demonstrates how his audio noise reduction system
operates. He A-B'd recorded tapes, made with and without the Dolby system.
Other components used here included Scully tape equipment, an Altec Lansing
audio amplifier, and giant Tannoy speaker systems.
--------- Nortronics displayed its magnetic
tape heads. The 3M Co.'s "Isoloop" professional tape recorder
with front panel removable printed circuit boards. Computron's BASF magnetic
recording tape line. Scully exhibited a broad line of tape equipment. Crown
displayed its 4new computer logic control tape machines.

AES Convention attendees prove that pro's and consumers share some things
in common. That's AUDIO's Ed Canby in the background. Do-it-yourself composition
of electronic music at Phase III's booth.
---- above: Lang shows line of recording and broadcast equipment, including
a new compact mixer and tape playback amplifier. Fairchild Recording's in-depth
line of professional components. Universal Audio featured an FET limiter and
test oscillator. Melcor displayed plug-in modules. Langevin showcased its mixers
and power amplifiers. Bruel & Kjaer exhibited test instruments, including
a new tape recorder for lab measurements. General Radio showed how its Strobotac
(electronic stroboscope) stopped motion of a speaker's vibrating cone so that
its movements can be analyzed.
