We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

68 THE TALKING MACHINE WORLD November 15, 1926 MATCHED IMPEDANCE Matched impedance is possible only in the newly developed talking machines. However, very excellent results may be obtained with the old style machines by designing the impedance of the reproducer to the nearest possible value. Onward-Upward-Forward in the science of better sound reproduction TN the ULTRA, you will find the SCIENTIFICALLY proportioned aluminum alloy, as fine as a human hair. Diaphragms by the hundreds were made before this final SCIENTIFIC alloy was achieved, shapes of all kinds were tested, used, improved. And the ULTRA is the final result of all these labors and improvements — the last word in reproduction. The early experiments produced some really good reproducers — you see some of them pictured below. But we believed that the horn of the old type talking machine was capable of still better results. The creation of ULTRA impedance Valves (see front construction of ultra) conceived and perfected in ULTRA made possible that well-known broad tone of ULTRA. The ULTRA, improved and perfected, has gained great popularity and demand. But we have not ceased to seek further perfection wherever possible. Under the direction of the well known acoustical and electrical engineer MAXIMILIAN WEIL, experimentation goes on day after day. ONLY the ULTRA has ADVANCED to meet the exacting requirements of the new electrically cut records. Other important features responsible for ULTRA superiority and demand will be explained from time to time. REMEMBER ; — The better your rec ords are reproduced the more of them you will SELL.
