Commentary
AD-2 series equalizer amplifier.
Like the AD-E1, it is designed to be compatible with low impedance MC cartridges, and by further expanding the compatible impedance, it is compatible with various MC cartridges.
Current input type is used for the circuit structure.
We have adopted only excellent transistors from domestic and overseas products for important transistors, and we have prepared specially the most important transistors.
In addition, an attenuator using a high-performance thin-film resistor or a precision resistor for sound is used for the resistors.
Film capacitors are used as smoothing capacitors for power supply circuits except for the power stage.
The power transformer, switch, printed circuit board, wiring material, etc. also use parts with consideration for sound quality.
