TONE CONTROL
DEVICE
Strength of High and
Low Notes.
The Introduction of the tone con- trol on radio recolvers has taken American listeners by storm, and the device now ranks almost equal to sensitivity and selectivity importance.
The tone control enables the per- son tuning in to change the tone quality to suit his faney, or to cor. reet acoustic faults in the roon. where the music is being reproduc-
ed.
Most of the sets equipped with the control have an extra knob on the tuning panel with the words, high, and low, on the ends of the scale. When the knob is turned to high, the high, notes are supposed to be brought into prominence, and when it is turned to low then the luw notes are louder.
What actually happens is this. The knob is connected to a rheostat in series with a condenser of pre- determined capacity, and the whole network is ennnected across ame part of the amplifier eircuit or the loud speaker. When the knob in- ercases the resistance in series with the condenser to a value high enough, the high notes come through with their real or natural intensity.
