Trying stereo and 5.1 surround sound effects

1. Open 14-2.prproj.
2. Drag Music Stereo.wav to the Audio 2 track. (Sorry! It cannot make sound in Audio 1 track.)
3. We cannot drag any mono audio effect to the Music Stereo clip.
4. Drag Effects > Audio Effects > Stereo > Balance to the Music Stereo clip.
5. Drag the Balance slider in the Effect Controls panel left and right while we play this clip.
This clip was mixed with the guitar panned all the way left and the honky-tonk piano panned hard right. If you move the slider all the way to either end, you will hear only one instrument.
The guitar sound might come from the left or right speaker,  so might the piano sound. It depends how we connect speakers to the amplifier and how we place them on the counter.
6. Add 2 keyframes, and have the audio pan from left to right and in reverse.
7. Play the clip.
The sound moves from left to right and, in this case, makes the guitar fade into the piano.
8. Delete Balance and apply Fill Right.
Fill Right (fill from the right)only plays the piano in both left and right channels and discards the guitar. Fill Left (fill from the left)only plays the guitar in both channels and discards the piano.
9. Drag Music 5.1.wav to the sequence, and Premiere adds a 5.1 audio track to accommodate this new audio clip type.
10. Mute the Audio track containing the Music Stereo clip by clicking the speaker button on the left side of the track label.
Not mute both Audio tracks, but only mute the Audio track containing the Music Stereo clip by clicking the speaker button on the the left side of that track label. There is a small error in Chinese translation.
11. Drag Audio Effects > 5.1 > Channel Volume to the Music 5.1 clip.
12. Play the clip and drag the sliders for each channel to experiment with this effect.
Should I use 6 speakers to experiment with it?

formant
Drifting away from us the old Russian satellite becomes smaller and smaller. We PAN with it as we SEE it's on a collision course with something huge.
pan: to rotate (as a motion-picture camera) so as to keep an object in the picture or secure a panoramic effect
honky-tonk:  country music that has a heavy beat and lyrics dealing usually with vice or misfortune
hard:  close in time or space         example: hard right
equalizer:  an electronic device (as in a sound-reproducing system) used to adjust response to different audio frequencies              What does it look like?
fit the bill:  be suitable
