I am using 2 speakers (Local Made) with amplifier placed near my monitor.
I want to know, is placing speaker near monitor have any -ve effect on monitor ?
Yes, if its not magnetically shielded.
I think only the amplifier affects colour, not the speakers. Therefore I have kept my speakers sideways to the monitor and the amplifier/woofer in the lower desk of the table.
It effects CRT only if not shielded. For LCD, it won't do anything.
Sometimes, the monitor will start showing green or blue at the edges due to the speakers. That can be fixed by degauss though.
Unshielded speaker magnets will affect a CRT monitor by changing the display colours, especially at the sides close to the magnet. The effect will change or go away if you move the speakers.
CRTs, including TV picture tubes, are sencitive to magnetic fields, including the earth's magnetic field. Therefore they have what is called a degaussing circuit built in. This applies a strong alternating magnetic field for a brief moment on switching it on, and demagnetises the tube.
The automatic degaussing mechanism works only if it is switched on from a cold condition. But some monitor models also have provision to degauss the tube manually while it is on, in addition to the auto circuit.
Spealers designed for use with computers have shielded magnets that do not affect the CRT.
Unshielded Speakers have Magnetic waves which gets conflicted with the rays of the cathode...since cathode is of -ve rays...it gets attracted to the speakers north pole and thus the colour distortion arises...prolonged use might also have this effect but it's in very rare cases...
Try not to keep them together for long time as it might make it into permanent damage...
Local made speaker.... i think its unshielded, so its better to keep it away from crt monitor, no problem with LCD though.
when u throw ur amplifier on ur monitor
it will surely affect the colours
