SE-A6MK2
Commentary

Control amplifier with wide D range design.

The equalizer section is equipped with a low-noise ICL equalizer circuit of parallel FET differential and MC basic design.

It employs a newly developed wide dynamic range volume that greatly improves the practical SN ratio. By combining a low-impedance volume with a high-performance drive amplifier, it prevents the SN ratio from deteriorating due to resistance changes.

By installing a SEPP buffer amplifier, a low-output impedance of 2 Ω is realized, and there is no high-frequency degradation caused by the shield wire when the power amplifier is installed remotely.

A newly developed low-distortion LSI for audio-only is used in the electronic switch for the input selector, which has succeeded in reducing distortion by nearly 20 dB compared with the conventional one. Moreover, audio and video signals can be separated on the printed circuit board, preventing degradation of audio signal quality.

The four input jacks (video/aux1, TV/aux2, tape2/VTR, and tape3/DAtape) are connected to the video input jacks, and the video can be switched using the input selector.

Equipped with video/aux1 inputs that can be used by switching the front / rear jacks.

Equipped with rec selector and tape monitor switch that can be used for 3 decks.

Equipped with Super Bus, Super Treble, and unique shelving control that enables more effective voice correction.

It is equipped with control functions such as subsonic filter and audio muting.

Equipped with a computer control terminal.
