It will be timely argument for the RCA line in your sales contract with the dealer, not forgetting the tie-up of general RCA advertising that is to follow. " It is our purpose to stand side by side with the distributor and the dealer in their sales efforts.

This Company is a subsidiary of the English Marconi Co., of which Mr. Marconi is the Chairman of the Board of Directors, and is also the VicePresident of the Canadian Marconi Company.

Ask Our Service Bureau The Mystery of Sound ALL resonant musical instruments give forth rich and mellow tones because they have resonant sound chambers. Human speech is vibrant because it is resonant through a series of graduated sound chambers and released through a perfect projector — the LOUD SPEAKER employs these principles. The sound impulse is taken from the head telephones and transmitted into a perfected sound chamber, the form and design of which is patented. Full sound wave energy is then obtained by setting in vibration a series of ten graduated chambers, the shape, proportion and size of which required months of research to determine. The sound is released through a projector, the curve of which is patented. There is no wave interference; sound from the Richtone is transmitted directly to your ear.
