Magnetic transducers are used in many types of audio equipment such as phono cartridges and tape or cassette recorders. They generally must be shunted by a damping resistor to give a flat frequency response. This often contributes to a large extent to the total system noise. A method is presented for the design of preamplifiers that greatly reduces this source of noise, giving an improvement of 3-6 dB in typical weighted signal-to-noise ratios.
