■ I²C CONTROL COMMAND DESCRIPTION

■MASTER VOLUME CONTROL

VOL

The attenuator is consisted of both the Volume1 and Volume2. The total attenuation level is summing of

each attenuation level of the Volume1 and Volume2. The attenuation for both the Volume1 and Volume2 are

always synchronized to have the same attenuation levels for each other, and are not controllable independently

for each other.

•”VOL” : Sets the total attenuation level for the both Ach and Bch(up to 84dB, 0.33dB/step)

■Channel Balance Control

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.
