ArcadeJunkie Posted January 27, 2015 Share Posted January 27, 2015 After converting the output of my Odyssey 2 to composite, I have been playing it much more lately. I also have "The Voice" accessory and im just getting annoyed with the fact that the sound comes from the speaker on the unit and not from the TV. I was toying with the idea of hooking up the red/white RCA output jacks to the back of the voice unit and tie them in with the already existing red/white output on the console itself. I have a fair amount of knowledge when it comes to electronics, but I was just wondering if anyone knows what would happen if you hook up 2 audio outputs into one audio input? Would they both play through the TV speakers together without issue? (ive attached a crude diagram for reference) Any help with this would be greatly appreciated. Thanks!

+LS650 Posted January 27, 2015 Share Posted January 27, 2015 I've been thinking of getting the Voice module for my O2, but they are _so_ expensive. I saw a fellow selling one on the videopac.nl forum a couple of days ago: he wanted 125 Euros - about $150 US. I just can't justify that kind of money for it.

CatPix Posted January 27, 2015 Share Posted January 27, 2015 People or prices are crazy. I picked a Voice last year on eBay US for 30us$ (plus shipping). Quote Link to comment Share on other sites More sharing options...

CatPix Posted January 28, 2015 Share Posted January 28, 2015 Mine is a bit weathered but nothing bad. Anyway, for your sound question, there is two options : First, tapping your sound output from the speaker. It's the most straightforward option. Tho it's strongly advised to put a resistor in order to avoid sending too much power into the TV amp. Second, picking up the sound right at the synthetizer chip output. This way the sound will be at low lever and need no protection. It may be too low for the TV tho. The first solution let you control the Voice level, and is easier to do. But you have to keep or remove the speaker. The second is more complex but you get the choice to keep the speaker. Quote Link to comment Share on other sites More sharing options...
ArcadeJunkie Posted January 30, 2015 Author Share Posted January 30, 2015 Thanks for the great advice! looks like i have a date with a soldering iron this weekend... Do you think hooking up 2 sources of audio output into 1 source input would allow for both sources to play at the same time on the tv?

CatPix Posted January 30, 2015 Share Posted January 30, 2015 (edited) Oh they will, no problems for this As I mentionned, the problem might be at the level output. The O² might be much louder than the Voice, or vice-versa. One solution would be to put the O² sound on one sound TV channel and the Voice on the other. It might sound weird tho Edited January 30, 2015 by CatPix Quote Link to comment Share on other sites More sharing options...
ArcadeJunkie Posted January 31, 2015 Author Share Posted January 31, 2015 Well..... I did the mod.... and I must say I am quite impressed! I just disconnected the speaker and wired those leads right to the rca output. The volume for both sound great! Some games are a bit louder than others, but the volume adjustment takes care of the difference! Thanks again for the help my friend! Now.... gotta see if I can integrate he voice and the base so the console doesn't look like it has a big tumor on it..... anyone know if any games don't work at all with the voice unit?

CatPix Posted January 31, 2015 Share Posted January 31, 2015 As far as I'm aware, only the Videpac+ only games may not work with the Voice, so you should be fine. Quote Link to comment Share on other sites More sharing options...
Rolo Posted January 31, 2015 Share Posted January 31, 2015 Most of them do. Also the Videopac+ games. Sometimes a short faulty sound sample of the voice can happen. Not working: BASIC CHESS I'll do some testing and try to find games, that don't work. Normally, I don't switch off "The Voice". Quote Link to comment Share on other sites More sharing options...
Rob Mitchell Posted October 28, 2015 Share Posted October 28, 2015 Well..... I did the mod.... and I must say I am quite impressed! I just disconnected the speaker and wired those leads right to the rca output. The volume for both sound great! Ok I can see asding a small speaker shut off jack on the Voice and a small input jack on the O2 and a short mono 1/8" jack cable between the the two. Thanks!

desiv Posted October 31, 2015 Share Posted October 31, 2015 (edited) After converting the output of my Odyssey 2 to composite, Wait, you were able to do that with an NTSC O2? Did you basically just hook up the wires and have it work, or did you have to add some electronics? I tried the basic video mod on mine but it didn't work. Saw some more complicated (not too bad looking, but) other things to try, but never found one I was confidant enough would work. I'd heard that that some O2's just work with the straight wiring and some don't... Any help would be.. er.. um.. helpful.. I do have a voice module, so once the mod is done, it would be interesting to send the sound to the TV. Tho I kind of like the speaker approach too. Reminds me of my pong unit.. Thanx, desiv Edited October 31, 2015 by desiv Quote Link to comment Share on other sites More sharing options...
