Equalized Stereo Preamplifier for Professional Use
Some of the necessary consideration in the design of a stereo preamplifier which will accommodate a multitude of different cartidge types under optimum conditions are discussed. Described also is an actual measurement of the distortion in an over-all stereo disk recording and playback process to investigate the comparison betwen amplifier performance and over-all disk recording-playback performance of today. Signal-to-noise ratio is compared to that of the magnetic tape medium, and the treble adjustment to correct for discrepancies in cartridge response is illustrated.
