M-06 α
Commentary

This power amplifier is based on the true pure A class system and has been developed by investing new know-how.

The M-06 α has been developed primarily for stereo use, but can also be used as a mono high-power amplifier.
When monaural is used, the coaxial monaural input or the balance input terminal of the cannon connector can be used for direct balance input without using an inverting amplifier.

The power amplifier uses a pure class A system that supplies a constant bias current up to the maximum output.

The power supply section uses a large-capacity toroidal transformer to ensure a stable power supply capability. It is also compatible with low impedance loads from 2 Ω provides excellent speaker drive capability.
In addition, by installing a separate transformer for digital display, interference with the signal system is strictly eliminated.

We use custom-made products such as electrolytic capacitors, copper styrofoam film capacitors, and wire rods.
In addition to PC-OCC wiring, nitrogen gas sealed contact relay, bus bar to reduce power source impedance, attenuator using fixed resistance, and large speaker terminal for very thick cable.

Equipped with a peak meter for digital display.
The display hold time can be switched to 3 levels of 1/3/5 seconds and peak hold is also possible. The display impedance can also be switched to 4/6/8 Ω and the meter brightness can be adjusted to 3 levels with the dimmer switch.
It is also possible to completely disconnect the display from the signal system by turning off the power of the entire display system.

Equipped with a line phase sensor that can detect the polarity of the AC power supply.
