摘要
A playback preamplifier for use on a recording machine utilizing a magnetic recording medium to provide a substantially flat response between a general range of 200 to 6000 Hz. and having a substantially improved signal-to-noise ratio. The circuit includes a three stage amplifier having an overall DC feedback loop. The magnetic transducer is connected in the feedback loop so that the DC feedback current biases the transducer with the DC feedback current.
