Amateur talking pictures and recording (1933)

HOME RECORDING EQUIPMENT 43 suitably provided with extra weights which are carried above the reproducer as indicated by the dotted lines. The remainder of the equipment consists of a control box with leads and adapters and hand microphone. The control box is a junction for the various connections, and at the same time enables spoken voice or radio programmes to be recorded either separately or together. Thus one may _. ;*Position of Weights *C — > <5S Recording Weights Fig. 22. Pacent Recordovox easily record direct voice with music taken from a radio programme as a background.

Thus, since low notes cause greatest sideways swing of the recording point there will be more tendency for the recording needle to jump. Thus it is reasonable to suppose that more weight would have to be provided. In reproducing all that is necessary to do is to remove the extra weight and use the pick-up in the normal manner. Dictating Machines. The present chapter would not be complete without reference to dictating machines which have carried on the work of home recording since the early days of Edison and the phonograph. In principal the dictating machine of to-day as exemplified by the Dictaphone, one of the most popular makes, is similar to the original phonograph employing wax cylinders. In mechanical construction, however, and in method of working the Dictaphone is quite a different proposition. An enormous amount of ingenuity has been displayed in making the processes of
