Crest Theatre Installs New Sound Machine
Millard County Chronicle, 6 July 1933, page 1
The Crest Theatre has installed new sound equipment that runs direct from the electric light system instead of the old way of using radio batteries.
The former system was hard to regulate as the current supplied by the batteries was not constant in volume and caused the machines to fade or increase in volume by turn. Under the new plan the should will always remain constant and true in sound and volume.
The old machines varied in tone cycles from 130 to only 600 so that both the very low tones and the high ones were not clear, whereas on the new machines the cycles embrace the range from 30 to 1500 so that the very lowest bass notes and the very highest violin notes will be clear.
The old machines have been sold.
