Input Awdjo: Connect your audio source (e.g., Tablet, DVD player, Laptop, PC, Smartphone, MP3/MP4 player) to the 'Audio input' RCA jacks on the preampbord aktar ħaj.
Output Awdjo: Connect the 'Audio output' RCA jacks of the preamplifier board to your active speakers or a separate power ampaktar ħaj.
Provvista tal-Enerġija: Connect a DC12V 1A power adapter (not included) to the 'Power 12V' input jack on the board.

Caution: Do not connect the preamplifier to a car's power supply.

4. Istruzzjonijiet Operattivi

4.1 Tixgħel/Jitfi

Once all connections are made, plug in the DC12V 1A power adapter. The tubes will begin to warm up. To turn off, simply unplug the power adapter.

4.2 Kontroll tal-Volum

Use the 'Total vol' knob on the front of the board to adjust the output volume. Start with a low volume setting and gradually increase it to your desired level.

5. Manutenzjoni

5.1 Tindif

To clean the unit, disconnect it from power. Use a soft, dry cloth to wipe down the surfaces. Avoid using liquid cleaners or abrasive materials.

5.2 Sostituzzjoni tat-Tubi

Vacuum tubes have a finite lifespan. If you notice a degradation in sound quality or if a tube fails, you can replace them. Ensure the unit is powered off and cooled down before attempting to remove or install tubes. Gently pull the old tube straight up from its socket and carefully insert the new compatible tube, aligning the pins correctly.

5.3 Ħażna

When not in use for extended periods, store the preamplifier f'post frisk u niexef 'il bogħod mix-xemx diretta u minn temperaturi estremi.

6 Issolvi l-problemi

Problema	Kawża Possibbli	Soluzzjoni

8. Għajnuniet għall-Utenti

Understand its Function: Remember this is a preamplifier, mhux qawwa amplifier. It processes the audio signal to add tube warmth and allows volume control, but it needs a separate power amplifier or active speakers to produce audible sound. It does not have an RMS output power rating as it does not drive speakers directly.
Irrumblar tat-Tubi: Experiment with different compatible tubes (e.g., 6J1, 6K4, GE5654) to find the sound signature that best suits your preferences. Ensure the unit is off and cooled before swapping tubes.
Power Supply Quality: Using a high-quality, stable DC12V 1A power adapter can significantly impact the performance and reduce noise.
