I have seen a few different mods about for getting 'Stereo' audio from the front loading NES console, so include pots on the 2 audio channels, another just had 1 dial on the rear of the console and ive recently seen Low-Gains one http://www.youtube.com/watch?v=2vxjL6KTyUs that doesnt use any pots. So which is regarded to be the ideal one to use. Also do any of the NES/Famicon systems have stereo out of the box?
AFAIK, all NES and Famicom variants can be modded for pseudo-stereo; "out of the box" implies that it has pseudo-stereo without any modding, which obviously isn't the case. It's really a matter of personal preference, if you'd like to adjust the volume of each channel depending on the game, then adding pots would be the way to do it. If you'd like to have them equal and at the proper gain for TV speakers, then use resistors instead of pots.
aren't the stereo mods just separating out some of the sound channels to different sides, not actual stereo?
Bingo. I prefer to duplicate the single output for stereo usage. Simply separating the channels doesn't do anything for me short of annoying the hell out of me and I can't stand having only one side of my stereo setup get used due to feeling like half my hearing went bad overnight.
But what about the mods where it just has a dial mounted on the outside of the NES case how does that work?...is it just a volume knob then? So you prefer to have a dual mono setup then by using a Y adapter for the audio RCA on the side of the NES? I guess Low-Gain's mod is the easiest one to do then http://lowgain-audio.com/NESmod.htm, it appears to amplify the audio aswell?? EDIT: Just read the info on his site.... "Pulse Channels ouput on Left Tri/Wave/Noise output on Right (all channels summed to mono if only LEFT output is in use) The output is boosted (fixed amount) to get you a bit more bang for your buck. This output amplifier also provides protection from reverse voltage spikes to your NES's main board."
i would just use dolby prologic ii if you use 5.1 home theater or double mono as APE said, if you use headphones or stereo setup. dolby prologic ii does some surround seperation even from mono sources.
