Bias Voltage of SD2931 ??

Post by XXL » Sun Apr 10, 2022 11:16 am

Datasheet says 100ma which is about 2.5v. Is this correct before I apply drive ? Iv never used this device before.

Thanks

Connect an amp meter to the PA, slowly increase the bias starting from 0v until you see current being drawn, keep increasing the bias until you see 100mA on the amp meter
