High level Anti-breaking sound open Low level Anti-breaking sound oﬀ Hang in the air Anti-breaking sound open X A9 108 Peripheral parameter setting Gain setting: XA9108 The ampliﬁer gain is set through the external input resistance Ri, and the gain setting follows the following formula: Av=490k/(Ri+15k), Among them, 490k is the built-in feedback resistance, and 15k is the built-in input resistance. Customers can choose according to their own requirements for gain. If necessary, set the value of Ri ﬂexibly. 4 of 5 8/4/21, 04:49 ANT8108 Product Manual V1.0 https://translate.googleusercontent.com/translate_f D A3 h A2 A 0.25 c L A1 L1 5 of 5 8/4/21, 04:49
