Balancing the sound levels in two channel stereo is simple and direct, but when three or four channels are used,
the task becomes more difficult. To enable the user to accurately set system balance, a steady test signal is played
in one channel at a time and the levels can be adjusted until they match each other. A mid-frequency noise signal is
used so that it will sound similar from all speakers in the system regardless of size or location.
