4.2. Soldering Components to PCBs

Carefully solder all resistors, capacitors, diodes, ICs, and other small components onto the two provided PCBs according to the circuit diagram. Pay attention to component polarity where applicable (e.g., electrolytic capacitors, diodes, LEDs, ICs).

Insert each component into its designated holes on the PCB.
Bend the leads slightly to hold the component in place.
Solder each lead, ensuring a good, shiny solder joint.
Trim excess leads with flush cutters.

4.3. Ceangalaichean Uèir

Connect the speakers, USB power cable, and 3.5mm audio input cable to the PCBs as shown in the wiring diagram. Ensure secure and correct connections to avoid malfunction.

Connect the speaker wires to the designated speaker output terminals on each PCB.
Connect the USB power cable to the power input on one of the PCBs.
Connect the 3.5mm audio input cable to the audio input on the appropriate PCB.
Connect the two PCBs together using the provided interconnecting wires, ensuring correct left (L) and right (R) channel connections.

4.4. Enclosure Assembly

Assemble the transparent acrylic enclosures for each speaker. The PCBs and speakers will fit into these enclosures.

Peel off any protective film from the acrylic panels.
Mount the speakers into the front panel of each enclosure using the provided screws and nuts.
Mount the assembled PCBs into the enclosure, aligning them with the designated standoffs.
Secure all acrylic panels together using the remaining screws and nuts to form the complete speaker boxes.
