Standby control description:

SD is the standby control terminal, low-level mute, high-level work (the control voltage can be from 3v-35v), the default is the working state when delivered, when standby control is required, the R1 resistor on the board needs to be removed, and the external control will do .

Description of gain setting terminal:

The default floating state gain is 40 times. If a higher gain is required, just short-circuit the two pin interfaces on the gain setting end, and the short-circuit gain is 54 times.

The signal input mode can be selected from the following two according to your needs:

1: Signal Balance Input (Differential): Signal+, Signal-,

2: Unbalanced input (single-ended): the - terminal is short-circuited with GND (ground), and the signal is input from the + terminal.

Note:

When the input is unbalanced, be sure to short-circuit the "-" with GND, otherwise the sound will be abnormal, and the chip may be burnt out in serious cases.
