"Now that I have received the first "batch" of my favorite classical records transferred to CDs, I am readying the second group to be converted. I am thrilled with the CDs; the quality is fabulous....better than the records. I gave away my record player, so I am just thrilled to be able to hear the best of my classical recordings again!"

Matching

Arranging for the impedances presented by a load to be equal to the internal impedance of the generator; this is essential to avoid loss of power. In mikes, the loss results in poorer signal-to-noise ratio. Matching is done by means of a transformer. Where mike impedance is strongly capacitative; e.g., in electrostatic types the output voltage is fed to the grid of a valve and controls the current in an external circuit.
