Commodore Plus/4 A/V Breakout

This device makes hooking up your plus/4 to a modern tv quick and simple.  

Composite out.

SVideo out

"Stereo Out" (Not TRUE Stereo. plus/4 Mono Audio is split to both R and L outputs)

Documentation:

The A/V-Adaptor allows to connect standard S-Video and Audio or Composite-Video cables to the A/V-Jack of the Commodore plus/4.
A 330 resistor to attenuate the Chroma signal for S-Video is installed, but it can be deactivated by setting a jumper (JP2). This attenuation is required, since the chroma signal has a level, which is too high for standard S-Video.

The two audio output jacks can are connected. This provides an audio signal output on both the Right and Left jacks.

Chrominance HI 
The chrominance signal has a too high level for the standard S-Video chroma signal. The jumper bridges the 330 resistor (R1) to switch off this attenuation.
