Figure 5.1: Basic Wiring Example
This diagram illustrates how to connect a 3.5mm audio input source, a DC 5V power supply (e.g., battery), and two small speakers to the amplifier ọkọ.
Step-by-Step Connection:
- So Awọn Agbọrọsọ: Connect your speakers to the 'R+' and 'R-' terminals for the right channel, and 'L+' and 'L-' terminals for the left channel. Ensure correct polarity.
- Sopọ Ipese Agbara: Connect a DC 5V power source to the '+DC5V' and '-DC5V' terminals. Observe correct polarity (+ to +, - to -) to prevent damage. The board features input reverse connection protection.
- So Igbewọle Olohun pọ: Plug your 3.5mm audio cable from your audio source (e.g., smartphone, MP3 player) into the 'Audio IN' port on the amplifier ọkọ.
- Set Mode (Optional): If desired, adjust the MODE jumper. By default, it is set to high electricity level (Class D). For Class AB, set it to low electricity level.
- Set Shutdown (Optional): If desired, adjust the SD jumper. By default, it is set to high electricity level (Shutdown Disable). For Shutdown Enable, set it to low electricity level.
6. Awọn ilana Iṣiṣẹ
Once connected, operate the amplifier board as follows:
- Agbara Tan: Ensure all connections are secure, then apply power to the DC 5V input. The power indicator LED on the board should illuminate.
- Iṣakoso iwọn didun: Rotate the volume knob clockwise to increase the audio output level and counter-clockwise to decrease it.
- Mu Ohun ṣiṣẹ: Bẹ̀rẹ̀ sí í gbọ́ ohùn láti orísun tí o so pọ̀ mọ́.
- Ipo Yipada: If you changed the MODE jumper, the amplifier will operate in either Class D (high efficiency, default) or Class AB (lower power consumption, higher fidelity for some applications).
- Iṣẹ tiipa: If the SD jumper is set to 'Shutdown Enable' (low electricity level), applying a low signal to the SD pin will shut down the chip. The factory default is 'Shutdown Disable' (high electricity level).
