Hello everyone,

Just recently advanced from 8mm to 16mm and I just purchased an EIKI RT-0 16mm sound projector. Can I hook my stereo up to it because it has just one 1/4 jack in the front. My Elmo 8mm HD-1200 I was able to do so but this EIKI has a completely different set-up for adding a sound system?

Or am I better off just using the projector's amp and adding a center channel speaker? And if so do I buy a 4ohm or 8ohm rear channel speaker?
Ant advise on the subject would be greatly appreciated!
Thanks,
Roger

You can just plug it in to your stereo system. Depending on what type you have you'll need a 1/4' jack to whatever inputs you have on the stereo. I would recommend getting one that splits into to channels such as 1/4' jack to rca stereo end. That way depending how fancy your stereo system is you can fake the stereo and surround so you don't just have a mono sound. I did that with my eiki 16mm and my receiver can fake the surround fairly decently. Granted it's never going to sound as good as true stereo or 5.1 but it's better than mono.

Hi Roger, I am not sure you have been given the right advice here. The jack socket is a loudspeaker socket for the 8 ohm speaker not a line out to feed the line in to an amplifier. I may be wrong but you could cause damage to both amps due to the miss matching. Ken Finch.

You are right Ken that it is a loud speaker jack out. You are also right that damage could occur, however you would really have to crank the volume on both the projector and the receiver before damage would occur. Plus I think the only damage would actually occur on the receiver end. If you want it to be perfectly correct you would have to get an inverter to reduce the power sound out signal into a line out signal. I think you can get these for about $20. It all comes down to if you want to take a risk.

For over 20 years I have patched my EIKIs 1/4" jack out to my stereo. Never 1 problem. You can add synthetic stereo with a device. I cant think of what they call it right now but will dig mine out and let you know.

Some years ago a circuit diagram was available on this forum for just this practice. The components were very cheap and a friend of mine built the device, which works very well. It prevents the projector output from accidental short circuit, provides two outlets for connection to a stereo amp (sound is still mono of course)and removes the low frequency muddiness which may
occur using a direct connection.

OK you guys are starting to scare me now because I sure don't want to do any major damage to both of the amps. Now Bill you say you went through your stereo using that 1/4 loudspeaker socket without having any problems? How do you regulate the volume on both the stereo receiver and the projector? Do you have them both at about the same low volume? Any information you can give me would be most helpful because I have the patch cords now and am anxious to hook them up but don't want to blow anything up!
Thanks,
Roger

Roger you will not blow anything up. I keep my projector volume about 1/4 of the way up from off and then use my receiver for the actual sound volume. I keep the projector just low enough for the actual signal to get to the receiver, because I am treating it as if it weren't an amplified signal. I do this so I don't risk damaging anything. I have also done this for years as well and I have never had an issue. You may occasionally get some low signal muddiness as Mal said which you can clean up using one of those inverters I mentioned earlier. Honestly Roger I wouldn't get too worked up, as long as you don't crank up the projector volume and the receiver, you won't blow anything.
