KK 遺作

今次吾係摩, 係改

揾返2003年其他一份遺留的作品, Marantz AV-9000

2 色差改 3 個色差

1. BA7613 x 3 (each IC have 3 switch inside)
2. Each IC for 1 unit. i.e. YUV signal into 3 diff. IC.
3. From data sheet, there are 2 pin (logic 0 or 1) to define the output status, see the attached photo.

4. In Marantz or some AV amp, they are only using 2 switch from a 3 switch device, (may be 3 input for top model).

5. You can simple jumping a extra YUV signal to the "unused" pin, when your AV amp is not select that TWO original source, your output will equal to your new signal source.

Still not understand, call me la.

Most of the AV amp can be "modify"
