I currently have a Super CD-ROM2 attached to a CoreGrafx II. My AV cable has always been attached to the Super CD-ROM2 av out.
I was looking at a way to optimize the video quality and a local guy offered me a PC Engine modded with RGB output. I was under the impression that plugging the PC Engine into the Super CD-ROM2 would never allow me to play CD games with RGB, only HuCards...
This morning I plugged the AV cable into my CoreGrafx II to test my theory and the CD game played just fine...
Why is there an AV outlet on the Super CD-ROM if the one on the CoreGrafx is sufficient? Am I missing something obvious?  :-k

PC Engine has no A/V out.  Well, no RCA jacks anyway.

i always thought you have to get audio out of the cd rom side.  you may be missing some of the sound by hooking it up how you did.  try playing a music cd and see if it comes out of the console to test.

I have a TG with A/V out on the side - I will try this. I thought I already did, but don't remember now.

The audio passed back to the system is mono.  Use the one on the IFU for stereo.

When the sound no longer works out of your Super CD-ROM² unit, you'll be glad you have that other option.  :P

The PC-Engine CoreGrafx has A/V out via A/V cable port on the side. The original PCE and TG16 do not (instead need adapters/boosters/or DIY cables).

The on on the CG only has mono CD sound mixed with stereo chiptunes. The SCD output is the one you normally want because it's the A/V of the original system, plus stereo mix of CD audio (and ADPCM).

 As someone else pointed out, if the audio amp circuit goes out on the SCD unit - you can always run it with mono CD sound mix via the other route until you can get it fixed.

I remember listening to CD tunes on my TurboGrafx-CD from the Turbo's RF output. It's all in mono of course since no RF jack on any console ever has been in stereo (though technically they could).
