Audio/Video Connector

Note: The connector used is a full size 8-pin 262° DIN, also known as the ‘horse-shoe’ type. A 270° DIN plug does NOT fit without violence.

The 8-pin DIN (audio/video) connector can output several different video signals, for each type you need a special assembled cable.

Output signals

• Composite (CVBS) (PAL)
• S-Video (PAL)
• RGB (PAL)

The Composite and S-Video cables are the same as you use for the original Commodore 64.

Pinout

Pin	Modulated Color	RGB Mode
1	Luma (Y)	Green
2	Ground	Ground
3	Audio Out Left	Audio Out Left
4	Composite (Y+C)	Red
5	Audio Out Right	Audio Out Right
6	Chroma (C)	Blue
7	Not used	CSync
8	Not used	Fast Switching

Audio

The audio outputs have consumer electronic line levels (Line Out) and need to be connected to an external amplifier.

Video

The video signals on pin 1, 4 and 6 have a source impedance of 75 Ohms, with standard 1V-peak video levels. In the modulated color mode, Luma and Composite contain sync information (-0.3V), while Chroma does not. The video blanking of the VIC output has been corrected, and is now in accordance with specification.

The PAL output is non-interlaced, with a field rate of 50.2 Hz, and line rate of 15.639 kHz.

The Fast Switching output is a 1.5V fixed ‘high’ output signal (when terminated with 75 Ohms), that is used on SCART to enable RGB mode. The CSYNC output is a sync-only output that is needed on the SCART signal as a replacement of the composite video or luma signal. In RGB mode, there is no sync information in either R, G or B; i.e. no ‘sync-on-green’.
