AKAI AA 5500
The whole page direct connection SEPP-ITL-OTL system circuit was adopted as the power amplifier part, and low distortion Oide power is realized.
Moreover, the ICZ stage direct connection circuit is used also for phone amplifier.
Four tape deck simultaneous connection is possible, and also a microphone jack with a level control, a muting switch, a bus treble control, a high / low cut, and a loudness switch are carried.
A power transistor protection circuit is built in and the Puri Maine independent use is also possible.
