Commentary
This is an integrated amplifier that condensed the know-how of making sound of the Macintosh tradition.
It uses an electromagnetic switch filled with inert gas. It is resistant to oxidation and enables distortion-free signal switching without contact failure over a long period of time.
The power supply section uses a Macintosh original R-core type power transformer. It can supply a stable voltage against AC voltage fluctuations and is resistant to noise.
It is equipped with a power guard in which the comparator limits the gain and suppresses output distortion when the input / output waveform difference exceeds the maximum power capability, and a sentry monitor circuit which monitors the dynamic operation time, voltage and current of the output stage and controls the current to be within a safe level.
In addition, protection circuits such as DC protection, temperature protection, turn-on delay and in-rush protection are employed.
Equipped with a Blue Eyes Power Meter that displays the actual output power.
