Here we offer a Siemens parametric equaliser 75-15, produced in Italy during (apparently) the 1960s, there are few pieces in the world.
The filters are based on R-C circuits (no inductors) and the EQ has 4 switching bands.
The circuits have discrete components with input and output transformer, driven by a Push-Pull stage. These EQs, are built with high-quality components and the possibility to select the mode of operation of each band. By pressing the ‘L’ button the circuit is excluded, with the ‘A’ button the EQ works in passive mode, and with the ‘E’ button the section becomes active, with a range of intervention of +14 dB on the selected frequency. Very high quality of the power supply circuit, whose care in construction reveals the professional destination of a device of this level.
