Hiya, I have recently reconnected my Technics SCE790 after not using them for eight months. It was pretty easy to set up but when I play a CD, it will play just one song before the volume cuts off. I can see that the CD is still playing as the monitor is still going but I cant har any sound. I have tried playing different cd's with the same result. I am only using three small speakers - two the same size and one slightly larger one which has '2 way 3 speaker' on it. I plugged the two smaller one's in the left and right sockets and the larger on the centre one. What could be the problem?

Looking at the specs for your system, the amplifier only puts out 23x2 watts. That means each speaker right now will get 23 watts (approx.). This amplifier is built to drive the load (the speakers) that is hooked up to it now. If you were to hook up another set of speakers, they would have to be pretty small (similar to what came with the system) with a higher impedance (over 8 would be good). The issue is the increased load/strain on the amplifier with the new speakers. However, if you are using relatively small speakers, with short run of speaker wire you should be allright (most amps have a temp protection built in, if the amp gets too hot it will shut off). To hook up additional speakers use the terminal that are there. You will 2 right speakers and 2 left. Place both positive ends of the right speakers in the positive terminal on the back of the amp (twist the ends together, if you must) and both negatives in the negative terminal, for the right speaker, on the back of the amplifier. Do the same for both left speakers.
In summary, you can probably hook another set up small speakers (which are only a short distance away from the amp) without much problem assuming you wont be pushing the amplifier to its limits all the time. You may find the amplifier lack punch or looses some sound quality though as the amp is not designed to be driving and controlling that many speakers.
Hope this helps
Darren Kelly-themasterofthrowdown...I've had mine since they came out in 1985. Here's what you do...Each of the 4 channels on the upper right function as an individual equalizer. You set each channel one at a time. So, you have the ability to change channels on your e.q. without resetting your faders(you just push ch. 1 2 3 or 4) and the sound of the music will change according to how you set ch 1 2 3 or 4)DON'T UNPLUG THE SH-8046 WHILE THE MUSIC IS PLAYING OR YOU WILL LOSE YOUR CHANNEL SETTINGS -ALL YOU BLUE LINES WILL END UP STRAIGHT ACROSS AND YOU'LL HAVE TO RESET THE 4 PROGRAMS (AGAIN) you don't have to set all of them*--Now, you set them with your finger (sweeping it up and down on the touch-screen (REMEMBER TO PUSH THE (LOCK) BUTTON FIRST)you have to unlockit it...then you have the ability to adjust you frequencies(the blue lines)once you have a good sound, YOU PUSH A NUMBER...say, 1...then push MEMORY then push 1 again...AND CHANNEL 1 will be set ---do the same thing for the other channels --IF YOU PUSH THE L or R button you can set the E.Q. channels different from each other (if desired --it's just an extra function...and both settings will appear on the screen. But I just keep mine both the same(Left and Right). When you record music(like I do - being a Musician) it is important to be able to listen to the play-back-SO YOU HAVE TO PLUG THE CD RECORDER BACK IN TO (PLAYBACK ON THE REAR OF THE sh-8046-(PUSH (TAPE) TO LISTEN TO YOUR TAPE RECORDERorCD RECORDER)to hear what you recrding sounds like.PUSH -SOURCE- TO GO BACK TO REGULAR PLAY MODE---If you ever walk in and cut you system on and nothing happens, check to see if on SOURCE or TAPE-(rec eq) on the bottom right is supposed to make the music sound better,push it to cut it on/off when you make tapes/CD's the red light should cut on ...Reverse --flips your EQ settings upside down(not such a useful function)....I guess that's all I can tell you, this is the only EQ I need for my overall system and I haven't bought another one for the mixer. IT HAS NEVER MALFUNCTIONED IN 25 YEARS -- I'M USING IT RIGHT NOW FOR MAKING PROFESSIONAL SOUND QUALITY CD's. SO HAVE FUN! Darren Kelly- email@example.com
Don't sweat it unless you're going to chain them to an electric arc wielder or something like that. I think your amp would cut out or the sound would get really bad long before a fire started. ;-)
Any typical amplifier that is NOT driven beyond it's capabilities will do just fine. Just make sure the impedance requirements of the amp and the speakers are in the same ballpark. Speakers being too low is possibly a problem but not dangerous, too high is no biggie.
We also had this same problem, make sure all speaker wires are correctly connected and have no breaks as any wire problems will cause amplifier to cut out. The system works fine now and also plays from the pc without any cut off. Hope this helps.
Does the system perform normally- as long as it works? If yes, then the Amplifier is at fault. It cannot be the output Transistors or IC, as the sound is coming from both channels. If you know solid state servicing, I advice replacing all the electrolytic capacitors in the Output stages of the Amplifier.
Over a period of time these El Caps dry out, and cause headaches.
If you listen to cd's and the sound dos'ent cut out then it cant be the amp. It could be the audio cables are intermittant between the amp and the dvd playerr or they are loose or corroded a little. or ppossible the input your using is going bad on the stereo sytem but I wouldnt think that the whole system was blown if the radio and the cd plays normal.. check out the causes I listed and let us know if you need more assistance\..:)
