This Balanced pre amp circuit is designed to amplify a little line-level audio signal (from 0 dB to 20 dB), and has balanced inputs and outputs. The scheme uses only conventional components, you’ll have no trouble finding in any electronics retailer. For a stereo version, simply to make two copies. Input stageThe input stage is focused on a four-op amp content in the TL084. It is mounted in a simple differential amplifier. It is true that this is not the best possible configuration, but it is much less critical than for a low stage level (preamp, for example) and give results, however, quite satisfactory.
