حفاظتي هدايتون

• سولڊر جي دونهين کي ساهه کڻڻ کان بچڻ لاءِ هميشه سٺي هوادار علائقي ۾ ڪم ڪريو.
• Use appropriate eye protection (safety glasses) when soldering.
• Ensure your soldering iron is placed in a safe stand when not in use and is unplugged when finished.
• Avoid touching the hot tip of the soldering iron or freshly soldered joints.
• سڀني حصن ۽ اوزارن کي ٻارن ۽ پالتو جانورن جي پهچ کان پري رکو.
• Verify correct component orientation (e.g., electrolytic capacitors, diodes, ICs) before soldering to prevent damage.
• Use a suitable power supply (12V DC) and ensure correct polarity when connecting power to the assembled circuit.

Follow these steps to assemble your Whadda WSAH1803 preamplifier kit. It is recommended to solder components from smallest to largest.

1. اجزاء جي سڃاڻپ: Before soldering, identify all components by their markings and match them to the corresponding positions on the PCB. Resistors are identified by color codes, capacitors by capacitance and voltage, and the IC socket and IC by their pin counts and notch/dot for orientation.
2. Solder Resistors: Insert the resistors into their designated spots on the PCB. Bend the leads slightly on the solder side to hold them in place. Solder each lead and trim the excess.
3. Solder Ceramic Capacitors: Insert the small, non-polarized ceramic capacitors. Solder and trim leads.
4. Solder IC Socket: Place the IC socket onto the PCB, ensuring the notch on the socket aligns with the notch marking on the PCB silkscreen. Solder all pins.
5. Solder Electrolytic Capacitors: These are polarized. Ensure the longer lead (positive) goes into the '+' marked hole or the square pad, and the shorter lead (negative) aligns with the '-' marking or round pad. Solder and trim leads.
6. Solder Potentiometer and Pin Headers: Solder the potentiometer and any pin headers or connectors according to the PCB markings.
7. Insert IC: Carefully insert the Integrated Circuit (IC) into its socket. Ensure the notch on the IC aligns with the notch on the socket and PCB. Apply gentle, even pressure until it is fully seated. Do not solder the IC directly unless specified; use the socket.

Once assembled, follow these steps to operate your mono preampزنده:

1. پاور ڪنيڪشن: Connect a stable 12V DC power supply to the designated power input terminals (usually marked +12V and GND). Ensure correct polarity to prevent damage to the circuit.
2. آڊيو ان پٽ: Connect your audio source (e.g., microphone, low-level audio device) to the audio input terminals (usually marked 'AF IN' or 'SIG IN' and 'GND'). This preamplifier is designed for mono signals.
3. آڊيو آئوٽ: اڳيون ڳنڍيوamplifier's output terminals (usually marked 'AF OUT' or 'SIG OUT' and 'GND') to an amplifier or active speaker system.
4. حاصل ڪرڻ جي ترتيب: Use the onboard potentiometer (often labeled 'GAIN' or 'RV1') to adjust the amplification level of the audio signal. Start with the gain at its lowest setting and gradually increase it to avoid distortion.
5. جاچ: Play an audio signal through your source and listen to the output. Adjust the gain as needed for optimal sound.

سار سنڀال

The Whadda WSAH1803 preamplifier kit requires minimal maintenance. Follow these guidelines to ensure longevity:

• صفائي: Keep the circuit board clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids.
• اسٽوريج: Store the assembled preamplifier in a dry, cool environment, away from direct sunlight and extreme temperatures.
• معائنو: ٽٽڻ يا زنگ جي ڪنهن به نشاني لاءِ سولڊر جوڑوں جو وقتي طور تي معائنو ڪريو. جيڪڏهن ضروري هجي ته ٻيهر سولڊر ڪريو.
• بجلي جي فراهمي: Always use a regulated 12V DC power supply to prevent damage from voltage fluctuations.
