Radio Engineers partnership founded by Al Kahn and Lou Burroughs to service radio receivers, located in the basement of the Century Tire & Rubber Company in South Bend, Indiana. The original investment was $30 and a second‑hand car.
A PA system is designed and built to assist legendary Notre Dame football coach Kntue Rockne at team practices:
"Seated in a specially constructed tower and speaking into a microphone, the noted mentor's caustic remarks will be carried to his team by means of amplifiers which will reach all parts of the practice field."
Rockne refers to the new system as his "electric voice," inspiring the company name. This PA is among the first — if not the first — custom‑made systems of its size, and marks the beginning of a new era in sound reinforcement.
Electro‑Voice incorporates. From Kahn in 1953: "The first block in this new business was the poor quality and high prices of available microphones. Sensing an opportunity, we purchased a lathe and drill press and began making them at the rate of one a week…"
- SPEAKER SYSTEM TO BE MADE HERE
A portable public address system capable of reaching approximately 300 persons will be manufactured by the Electro‑Voice Manufacturing Company, Inc., which Saturday filed articles of incorporation with the secretary of state in Indianapolis.
The incorporators are Albert Kahn and Louis Burroughs, partners in the Radio Engineers, Inc., 119 West Colfax avenue, and Mr. Kahn's father, Maurice L. Kahn, of 1069 Riverside Drive. The new company will manufacture its product on the third floor at 119 West Colfax Avenue, according to Albert Kahn. The incorporation calls for a capital stock of 100 shares at $10 par value.
- Rockne to Coach with Amplifiers
Knute K. Rockne, who has made Notre Dame football teams the talk of the country for many years, will coach his 1930 aggregation "by remote control" as it were, by means of a public address system. Seated in a specially constructed tower and speaking into a microphone, the noted mentor's caustic remarks will be carried to his team by means of amplifiers which will reach all parts of the practice field. Coach Rockne was ill last season and most of the winter and while his physical condition is said to have greatly improved, he is expected carefully to conserve his strength for the arduous duties that will be his this coming fall in whipping another championship team into shape.
The apparatus which he will use is the product of Albert R. Kahn and L. R. Burroughs, South Bend young men who are manufacturing and marketing it under the name of the Electro‑Voice Manufacturing Company, Inc. Their headquarters are at 110 West Colfax avenue. They entered into a contract this week with Mr. Rockne to furnish him the paraphernalia in time for the opening of the practice season.
Noise Cancelling microphone production required by the military dramatically increases production at EV. Total production reaches close to one million microphones annually.
EV moves to Buchanan, Michigan, consolidating in one place and setting the stage for entry into a number of consumer audio markets. EV quickly becomes a highly integrated manufacturer, with in‑house tool making, die casting, plating, painting, coil winding, and more.
