To control the balance between Ach and Bch, the both commands “CHS” and “BAL” should be set. For example,

to move a sound image to Ach-side, Bch should be attenuated with no attenuation on Ach. The command “CHS”

defines the channel should be attenuate, and the command “BAL” defines the attenuation level itself. The

attenuation for the balance control is consisted of the both Volume1 and Volume2, has the same structure with

Master Volume Control described above.
