6. عملیاتي لارښوونې

6.1 بریښنا کول / بندول

The BK-SAM300 offers three power-on modes:

• لاسي حالت: ترتیب کړئ ریموټ چالان کړئ switch to "Manual". Press the front panel د بریښنا تڼۍ د بدلولو لپاره ampژوندی یا بند.
• د موټرو حالت: ترتیب کړئ ریموټ چالان کړئ 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.

۶.۳ د کنټرولونو تنظیم کول

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 (د کراس اوور فریکونسی):
  • که د کارولو په صورت کې LFE ننوت, this control is bypassed. Set your AV receiver's subwoofer crossover frequency.
  • که کارول کیږي لاین IN or سلام په کچه, 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.
• PHASE (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.
• د بیس بوسټ: Use the BASS BOOST controls (Level and Freq) to fine-tune the low-frequency response.
  • فریق: Select the specific low frequency (25Hz to 50Hz) you wish to boost.
  • کچه: Adjust the amount of boost (0dB to 12dB) at the selected frequency. Use sparingly to avoid muddy or boomy bass.

7. ساتنه

• پاکول: سره نښلول amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or aerosol sprays.
• وینټیلیشن: Ensure that the ventilation openings are not blocked by dust or debris. Periodically check and clean if necessary to maintain proper airflow.
• ذخیره کول: که ذخیره کول ampد اوږدې مودې لپاره د لایفیر سره، د بریښنا څخه یې جلا کړئ او په یخ، وچ ځای کې یې وساتئ، د مستقیم لمر وړانګو او سخت تودوخې څخه لرې.
