Devices to Convert Stereo Audio into Mono for Commodore 1702

Post by DatPhosphorGlow »

Please disregard the bluntness, I'm copying and pasting my thread from another forum.

I need to connect stereo devices (SNES, N64, PSX, etc.) to my Commodore 1702 video monitor that only has composite mono sound output. I understand a Y cable is not the proper way to do this. I also understand that a proper cable can be cheaply and easily built with a soldering iron, some resistors, and a few minutes.

However, I want a plug and play product solution to this issue.

Yes, I have searched. I did find some solutions, but the threads are dated. Maybe there are now more products for this purpose?

The cheapest product I have found is the Monacor SMC-1. I wanted to know if anyone knows of any other product(s) that is/are capable of doing what I need in a similar or preferably lower price range.

I recently researched this for a PVM that only has mono input.

Lots of conflicting opinions out there on this. The argument I decided to buy was this: All modern audio outputting devices, like the ones you mention, have a high* internal impedance. This means you can simply use a Y cable and the signals cannot flow back up each other and cause problems.

I have had no problems using a SNES and Genny with a Y cable.

* edit: I should say "high enough"

If I were you, I'd do this myself. You only need a soldering iron and a couple of resistances. Very low soldering skill required, since you're just soldering resistances with cables and you can HARDLY screw anything up.
