The multifunctional equalizer "Eldorado MF-01" is a preamplifier designed to amplify and equalize signal from MM and MC cartridges for vinyl players and from the magnetic heads of reel-to-reel and cassette recorders. In RIAA MM mode only tube amplification is used, in RIAA MC and IEC, NAB / AES, Type I, Type II-IV modes a semiconductor low-noise preamplifier with the possibility to manually select the gain is additionally used. The equalizer is made in one case, which makes it more convenient to use at home. The functionality of the "Eldorado MF-01" can be understood after reading the controls in Figure 1 and in table 1.
