5. Setup
Follow these steps to correctly set up your ampbord aktar ħaj.
Dijagramma tal-Wiring:
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 ampbord aktar ħaj.
Konnessjoni Pass Pass:
- Qabbad l-Ispeakers: 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.
- Qabbad il-Provvista tal-Enerġija: 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.
- Qabbad l-Input tal-Awdjo: Plug your 3.5mm audio cable from your audio source (e.g., smartphone, MP3 player) into the 'Audio IN' port on the ampbord aktar ħaj.
- 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. Istruzzjonijiet Operattivi
Once connected, operate the amplifier board as follows:
- Qawwa Mixgħul: Ensure all connections are secure, then apply power to the DC 5V input. The power indicator LED on the board should illuminate.
- Kontroll tal-Volum: Rotate the volume knob clockwise to increase the audio output level and counter-clockwise to decrease it.
- Daqq l-Awdjo: Start playing audio from your connected source.
- Bdil tal-Modalità: 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).
- Funzjoni ta' Tfigħ: 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).
