BASICS: Left-Right channels.

[sunder]

Hello Audio(2 channel) friends, Please share your knowledge with me
as I dont know the technical things that: In the Stereo sound, Left
side is ever sounding sharp & with more strength than the Right, OK.
Is there any universal norms on 'Stereo Recording' as to be differentiated
between channels with left should be stronger than the Right? If so, why
particularly Left is stronger? Any reason according to Human hearing?
Then: Are the stereo opamps or other decoders produced as to work as
the music to be reproduced as left should be more sharp &strength?. Then:
Is it right that balancing the Left-Right to make proportionaly to equal by using the 'balance control'? or Is it right that just leave the control in the
centre as the music comes as recorded? Some companies dont put balance
control in the amp. So Please clarify these doubts.
Thank you,
Regards,
sunder.

Properly set up a stereo system should play the main voice or instrument right from the dead centre between the two speakers. All CDs are recorded to work that way.

Modern amplifiers do not have balance control. Unlike AVRs where you can change the relative amplitude between the speakers, you cannot change the settings in a two channel amplifier.

If you are getting unbalanced sound, there could be various reasons:

1. One of your speakers is not working properly
2. There is reflection from a wall near one speaker that is distorting the sound.
3. One of speaker cables is not working properly
4. The positioning of the speakers relative to the hearing position is incorrect.
5. The speakers have not been toed in properly.
6. One of your ears is more sensitive than the other.

Cheers

Thank you Venkatji, your 5th point is the correct one according to my set up.
Then now I have positioned as exactly 30 degree as toed-in.
Once again thank you.
Best regards,
sunder.

besides, ur 6th point isnt of much significance. at any given time, ur right ear is listening to sound from both speakers and so is ur left ear. if ur hearing aint proper, the thing that suffers will be overall sound but mostly stereo imaging .

Venkat sir ,
What is Toed .Sorry My Basics On Much specially speakers Is Still Flawed .

but mostly stereo imaging .

And that is exactly what the OP was talking about.

What is Toed .Sorry My Basics On Much specially speakers Is Still Flawed .

Toeing in is a way of creating a sweet spot where the sound from the left and right speakers will merge accurately for your ears. This is done by turning the speakers as a slight angle inwards towards each other and not keeping them parallel to each other. Generally, toeing is done by drawing a imaginary point some 5 odd feet behind, drawing lines from the speakers to that point, and aligning the speakers with these lines. The speakers and the point will form the three points of a triangle.

toe in is reffered to position your speakers slightly at an angle towards your listening position rather than placing them straight . This helps to create a better stereo image as well as better sweet spot.
Why toe in helps? --
Because the efficiency of a tweeter in a speaker is measured on its axis(90 deg) and it sharply decreases as we move off axis, so depending upon the on axis efficiency data of the tweeter the toe in angle can be determined or it can be done by simple hit and trail.
