Treble Band Circuit
The shelving characteristics can be obtained for the treble band.
The equivalent circuit and calculation formula during boost are indicated below.
Calculation example
Specification Set frequency: f = 26000 Hz
Gain during maximum boost: G
+10 dB
= 10 dB
Using R1 = 16.240 k
and R2 = 35.461 k
, and inserting the above values in the following formula, we
obtain:

Usage Cautions
Upon power application, the internal analog switch status is undefined. Use an external countermeasure such as
muting until data is set.
When performing initial setting after applying power, send the initial setting data for the left and right channels
prior to canceling mute.
To ensure that the high-frequency digital signals sent to the CL, DI, and CE pins do not spill over to the analog
signal block, either guard these signal lines with a ground pattern, or perform transmission using shielded wires.
