SE-A1000MK2
Commentary

Stereo power amplifier using MOS class AA circuit.

The SE-A1000MK2 uses a MOS class AA circuit unique to Technics.
This circuit consists of a pure class A voltage control amplifier that uses a MOS FET to control the output terminal and a current supply amplifier that uses a bipolar transistor to supply current to the speakers, which are combined by a Class AA Bridge. Therefore, separate amplifiers are used to amplify the input voltage and supply current to the speakers. The effect of the Class AA Bridge prevents sound quality degradation due to the back electromotive force of the speakers.

A newly developed Take II electrolytic capacitor has been adopted.
This capacitor is an upgraded version of an electrolytic capacitor that uses a bamboo fiber mixed separator. In addition to increasing the mixing rate of bamboo fiber, spiral copper wires are attached to the exterior of the aluminum electrolytic capacitor and fixed with polyolefin sleeves to improve electrical and mechanical performance.

Two types of input terminals are installed : Direct and Normal with level volume.

Equipped with a large meter that can read directly from a 0.001W minute signal.
The back panel is equipped with a switch to turn on / off the power meter light.

OCC wire material is used for internal wiring.

Uses a high-capacity OFC power cord with polarity display.

Gold-plated input terminal is used.

Speaker terminal compatible with banana plug is adopted.
