AU - α 205
Commentary

A pre-main amplifier of the α -07 series with the technology polished by the α -05 series.

The transmission and amplification circuits are arranged rationally in a spacious chassis size, thereby reducing adverse effects such as signal jumping in the circuit that causes sound quality degradation.

Equipped with CD direct function to transmit digital signal of CD directly to power amplifier section.

Tape2 is equipped with a REC monitor function.
