Usage Cautions
(1) Request to send the initial data at power ON
• Though the circuit initializing the IC inside at power ON is incorporated, be sure to send data to all sub-address as the
initial data at power ON.
• At power ON, muting or other measures must be taken externally till the data is set.

(2) Data is switched by standing up about the ACK clock of the data setting bit.
(3) The auto increment function is moved in the SUB address as follows.
…=>DATA_1=>DATA_2=>DATA_5=>DATA_6=>DATA_26=>DATA_29=>DATA_30=>DATA_31=>DATA

(4) As for the mixing function, half the value in which the Lch volume output and the Rch volume output are added is
output. (Lch+Rch)/2. Please set +6dB if necessary in the output steps.
