SOURCE: no sound from turntable bought for our hi fi system

Hi droopydraws
I don't know this specific system, but the connections are much the same on most set ups.

Turntable sockets on most amplifiers are referred to as "phono." So the first thing to do, is look on the back of the tuner/amplifier for a pair of sockets that are marked "Phono - L" and "Phono - R." The L and R are for left and right. Connect your turntable should be connected to these sockets. Your tuner/amplifier should have a button or setting to select "Phono" and you should then hear sound from your turntable. If it doesn't work there are two possibilities.

1) The phono input on the back of your tuner/amplifier might be faulty. You can check this very easily by temporarily plugging your CD player or Cassette Deck into the phono input sockets then selecting phono as if you were using the turntable. If there is still no sound, there may be a problem with the switching circuit. If there is sound, the problem will be associated with your turntable. Please note, anything plugged into the phono input will sound tinny, except the turntable because the frequency response is set for optimum sound quality when used with a turntable and not with other sound sources.

2) If you suspect the turntable, carefully remove the headshell and look at the small connections to the stylus, ensure they are firmly pushed onto the pins.

Hope this helps. Regards

My technics sh-eh780 stereo seems to work but the sound is very dull in sound

Unless there's an issue with internal components of the amplifier or speakers, a common cause of this is reversed speaker polarity.

The wires between the + and - terminals of the speakers MUST connect to the same + and - terminals on the back of the stereo amplifier. The speaker wires that came with the stereo are color coded to help prevent mis-wiring. If you did not pay attention to this or used different wires for any reason, you need to ensure that the wires between the each of the speaker's 4 terminals connect to the correct group and + / - terminals on the amp.


See page 6 of the manual here:

Make sure that the surround and center speakers are connected correctly, too.

Good luck!

Check the integrity of your speaker wire, make sure they are 'phased' (-+) properly, also check all other connections, it sounds like the protection ...

When I play a tune there seems to be no base coming though even tho I have replaced the stylus's

Are you speakers configured correctly? The receiver may have bass turned off, or lowered. I doubt it is your cartridge.

What is Phasing and how to set it up

he phase control will help the sound waves from your sub get synced up with those coming from your main speakers. If they arrive out of phase, there's the tiniest delay between **** Jagger's voice and Bill Wyman's bass, for instance. An easy, accurate way of setting the phase control is to reverse the connections on your main speakers (the black wire goes to the red terminal and the red wire to the black terminal). Now play a simple selection, like a jazz instrumental with a good walking bass line, on your system while you're sitting in your listening position. Have a friend dial the phase control on the sub until you hear the least amount of bass. Leave the setting there. Returning your speaker wires to their proper places will now allow you to hear the most bass from your sub.

An equaliser is, put simply, a more complex tone control, giving you the ability to cut or boost more specific frequencies than a tone knob, or bass & treble controls.

It comes in handy for tweaking the sound from your hi-fi to just the way you like it. But beware, as it can make your hi-fi produce sounds that are so bass or treble heavy, that you can damage your speakers if you're not careful.

Adding another compnent into the chain (like a graphic EQ) can add a little background noise but this Technics EQ is a pretty quiet one & you probably won't notice the noise apart from when there's no music playing & you've got the amp turned up high.

If there is significantly less bass even though the speakers are moving approximately the same as before, you may have one speaker wired out of phase. Disconnect one speaker. If the bass increases, double-check your wiring.
