easy balance adjustment of the channels. The test signal
"travels" from channel to channel. Adjust the sound level for
the same apparent loudness from each channel at listening

The center speaker helps achieve precise sound positioning over
a broad sound field.
The surround speakers enhance the "depth" of the sound field.
