Radio age (Jan 1927-Jan 1928)

SB You re there with a Crosley A tremendous Crosley radio achievement for 1927-28 Recent court decisions which clarified the radio patent situation have paved the way for still greater Crosley triumphs. Now — completely available to Crosley— and amplifying Crosley supremacy in fullest measure, are the enormous resources, great discoveries and ideas embodied in patents of 1 — The Crosley Radio Corporation. 2 — The Radio Corp. of America. 3 — The Westinghouse Co. 4— The General Electric Co. 5 — The American Telephone & Telegraph Co. 6 — The Hazeltine Corporation. 7 — The Latour Corporation. under which Crosley is now licensed to manufacture. Here are the seven big tilings which represent radio's greatest advancement, brought together by Crosley and combined with the experience, mass production method and leadership of the Crosley organization. No wonder a waiting radio world pronounces the "Bandbox" at the unprecedented price of $55, Crosley's paramount achievement. The Bandbox is Shielded Radio coils are surrounded by magnetic fields similar in every respect to the magnetic field around the earth that moves the needle of a compass but around radio coils these fields make nuisances of themselves by feeding back on each other. Heretofore it has been customary to make inefficient coils with inefficient fields to prevent such feeding back. The Crosley Bandbox incorporates copper shields around each coil to prevent such feeding back. The coils consequently can be made and are very much more efficient. The amplification of the receiver is, therefore, much higher— the sensitivity is greatly increased. Condensers are also completely shielded from each other in separate metal compartments. Hitherto, only high priced sets have enjoyed this super radio advantage. There is No Oscillation The Bandbox employs completely balanced or neutralized radio frequency stages to prevent oscillation, instead of the common form of losser method. More costly, to be sure, but extremely neccs • ary in achieving such results as are obtained by this marvel of radio reception. For Sharpness — The Acuminators "Bandbox" acuminators enable "fishers" for distant stations to bring them in loud and clear. As powerful telescopes magnify distant scenes, acuminators increase the volume of far-away signals so they seem like local programs. Volume Control This is another big "Bandbox" feature which permits full brass band power for those who want their dance notes strong and loud. For others, it cuts volume down to a soft and gentle murmur, without distortion. Illuminated Dial A Master Station Selector has an illuminated dial for easy reading in shadowy corners. A single knob permits full tuning for ordinary reception of local, nearby and super-powered stations. Installation Simplified A woven cable, containing vari-eolored rubber covered leads makes installation and hook-up easy for the veriest novice. No waiting for the radio service man, should the batteries be changed. Easily Adapted to Consoles Simply remove screws in escutcheon and in base of set. Lift off metal ease. Chassis now stands ready for installation in console cabinet. Opening in console cabinet permits control shafts to protrude. Escutcheon screws in place and — Presto! the console radio is complete. For A C Operation a special Bandbox is available at $65, wired specially for use with the Crosley Power Converter at .$(>(). This special Bandbox utilizes the new K.C.A.
