Power supply: 7.5V to 24V, 6A maximum 2. 0 V to 1VRMS (max) audio signal source, ≤ 600Ω. 3. Speaker: 4 Ω or 8Ω. Setup Condition for 24V Operation 1. Connect + and - speakers terminals to OUT and GND pins of CN2 and CN3 respectively. 2. Connect the + and 1 power supply terminals to Pin 1 and 2 of CN1 respectively. 3. Adjust the power supply to 7.5 ≤ VCC ≤ 24V, (do not turn on). 4. Connect the audio input signal source to the amplifier inputs (IN1, IN2). 5. Turn on the power supply to apply power to the board. 6. To enable the board apply a voltage, 2V ≤ VEN ≤ 6V, to the EN pin. To disable the board connect the EN pin to ground.
