Image of A-717V
Commentary

A stereo pre-main amplifier based on A-717 and equipped with S terminal.

It inherits all the technologies used in the A-717, such as direct construction, vibration-free and resonance-free construction, and low-load drive construction.

Equipped with S jacks for two input systems and an output Route 3, it is possible to dub each other by video selector while maintaining high quality image.

The power supply for video is equipped with a dedicated transformer, and the circuit and ground for audio and video are separated to minimize adverse effects on sound quality.
Also, if the V function is set to OFF, the power supply for the video system is turned OFF, preventing interference with the audio system circuit from the root, and the system is designed to be compatible with video while maintaining superior sound quality.
