6.1 ማብራት / ማጥፋት

The BK-SAM300 offers three power-on modes:

• በእጅ ሁነታ: ያቀናብሩ በርቀት አብራ switch to "Manual". Press the front panel የኃይል አዝራር ለማዞር ampማብሪያ / ማጥፊያ አብራ ወይም አጥፋ።
• ራስ-ሁናቴ ያቀናብሩ በርቀት አብራ switch to "Auto". The amplifier will automatically turn on when an audio signal is detected at the inputs and will enter standby mode after approximately 15-20 minutes of no audio signal.
• 12V Trigger Mode: Connect a 12V DC trigger cable from your source component (e.g., AV receiver) to the 12V TRIGGER IN terminal. Set the በርቀት አብራ switch to "12V Trigger". The amplifier will power on/off with the source component.

6.2 የማስተካከያ መቆጣጠሪያዎች

Optimal sound quality depends on proper adjustment of the amplifier's controls to match your subwoofer and listening environment.

• GAIN (Volume): Start with the GAIN control at its minimum setting. Play some audio with significant bass content. Slowly increase the GAIN until the subwoofer's output blends seamlessly with your main speakers. Avoid setting the gain too high, as this can lead to distortion.
• FREQ (Crossover Frequency):
  • የሚጠቀሙ ከሆነ LFE ግቤት, this control is bypassed. Set your AV receiver's subwoofer crossover frequency.
  • የሚጠቀሙ ከሆነ መስመር ውስጥ or HI ደረጃ ውስጥ, adjust the FREQ control to blend the subwoofer's output with your main speakers. A good starting point is typically 80Hz-100Hz, but this may vary depending on the size and frequency response of your main speakers. Smaller main speakers usually require a higher crossover frequency.
• ደረጃ (0° - 180°): The phase control helps to ensure that the subwoofer's sound waves are in sync with your main speakers.
  • Play music with a consistent bass line.
  • While listening from your primary listening position, slowly adjust the PHASE control from 0° to 180°.
  • Stop at the position where the bass sounds the loudest and most impactful. If the bass sounds weak or hollow, try adjusting the phase.
• ባስ ጨምሯል Use the BASS BOOST controls (Level and Freq) to fine-tune the low-frequency response.
  • ፍሬቅ Select the specific low frequency (25Hz to 50Hz) you wish to boost.
  • ደረጃ፡ Adjust the amount of boost (0dB to 12dB) at the selected frequency. Use sparingly to avoid muddy or boomy bass.

• ማጽዳት፡ ግንኙነቱን ያላቅቁ amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or aerosol sprays.
• የአየር ማናፈሻ; Ensure that the ventilation openings are not blocked by dust or debris. Periodically check and clean if necessary to maintain proper airflow.
• ማከማቻ፡ በማከማቸት ከሆነ ampለረጅም ጊዜ ሊፋየር፣ ከኤሌክትሪክ ያላቅቁት እና ቀዝቃዛና ደረቅ ቦታ፣ ከቀጥታ የፀሐይ ብርሃን እና ከፍተኛ የሙቀት መጠን ራቅ አድርገው ያስቀምጡት።
