Stereo preamplifier and equalizer for raising the low output of cassette head to a level that will drive the TAPE-IN input of a stereo amplifier or any stereo preamplifier.
The circuit uses a TDA1522 IC that is specifically designed for the task and provides very low distortion (0.05%), high amplification factor, excellent frequency response (20Hz-40kHz) and includes compensation circuits for the proper equalization of the signal.
The board includes a MUTE function which can be activated by connecting it to the earth.
