The talking machine world (July-Dec 1927)

The Talking Machine World, New York, October, 1927 ^hen ihe hall goes round ihe end for yds. Several different names have been used for the fine tuning adjustments on radio sets. It is well-nigh impossible to build a set in the factory so fhat the three or more tuned circuits will always be adjusted exactly to far away or weak signals. So the Acuminators were developed as secondary adjusters. For nearby or powerful stations they are never needed. The name "Acuminator" was coined from the word "acumen." With all ordinary local broadcasting which is reasonably strong, the adjustment of the circuits with the master selector is plenty close enough. Full volume is easily obtained. But for the very weak and distant signals and in order to get the highest possible degree of amplification, to bring them up to maximum volume, it is necessary that the circuits be tuned very exactly. The Acuminators provide for this. They are very fine tuning adjustments on the first and second tuned circuits and permit the user to tune these two circuits exactly to the same signal to which the third circuit has been adjusted by the master selector. The first two circuits will, of course, be very nearly right but with the Acuminators they can be made exactly right. The effect of the Acuminators is a good deal like usir^g a telescope. They bring the weak, distant signals closer like far-away scenes are brought into the foreground. The Acuminators are an additional refinement provided on Crosley receivers in order that the user may get the maximum possible results. th fHIS new Crosley Sandbox 6 TUBE RECEIVEK c/e /uxe is the nafional radio hit at The "All American" radio of 1928! With license to participate in the enormous radio resources of The Radio Corporation of America, The General Electric Co., The Westinghouse Co., The American Telephone and Telegraph Co., and The Hazeltine and The Latour Corporations, the Crosley Bandbox of 1928 is an "eleven" of super-efficient features and amazing co-ordinated performance. In it are incorporated: 1 — The best idea of balancing. 2 — The best ideas of shielding. 3 — The best ideas of sharp tuning. 4 — The best idea of controlling volume. 5 — The best idea of station selection. 6 — The best idea of finish and color. 7 — The best idea of power tube use. 8 — The best idea of console installation. 9 — The best idea of power supply connections by enclosing all leads in a cable. 10 — The best idea of AC tube operation. 11 — The best idea of converting AC current to . necessary radio DC. Operation of the Bandbox receiver from house current is possible with the AC model at $65, which uses the new amazing R.C.A. AC tubes. Power converter costs $60 more. These new Bandbox receivers are now on display at over 16,000 Authorized Crosley dealers. Their faultless reception of the many wonderful events constantly on the air is proving such a startUng demonstration that a national enthusiasm sweeps the country in the natural exclamation — "You're there with a Crosley!"
