H-3 Headphone + M-20 Amplifier Set
Product Description
The H-3 Headphone + M-20 Amplifier Set electrostatic loudspeaker is very simple in concept, but difficult to construct successfully in practice. lts operation relies on electrostatic attraction and repulsion, in much the same way as a piece of thin paper attracted to a rubber balloon that is charged by rubbing it against fabric.
Imagine a normal speaker as a point source, from which the sound waves produced diffract at a great angle. This causes rapid decrease in volume and quality over a short distance. Then imagine a flat electrostatic panel producing sound from the same input signal. This time the sound waves are produced over a large, flat area, therefore they have very little diffraction, and the volume decreases much less over the same distance. That's the difference that makes this amplifier incredible.
The electrically charged ultra-thin conductive film diaphragm is tensioned and placed close between two metal grids. When a high voltage audio signal is applied to the metal grids, the diaphragm moves in response to the signal, moving towards the grid which at that instant is oppositely charged, and away from the grid which has the same charge as the diaphragm. The diaphragm responds in an essentially linear manner, producing sound waves which are a very accurate reproduction of the original sound. This set brings your favorite artists right to your ears, with incredible sound quality that is perfect for even sound editing artists.
