سيٽ اپ ۽ تنصيب
Proper installation is crucial for the amplifier's performance and safety. It is recommended to have this unit installed by a qualified professional.
چڙهڻ جو هنڌ
Choose a mounting location that is dry, well-ventilated, and away from direct sunlight or heat sources. Ensure sufficient airflow around the amplifier's heat sink. The amplifier is designed for freestanding mount.
وائرنگ ڪنيڪشن
- Power Connection (12V): Connect the main power cable from the amplifier to the positive terminal of the vehicle's battery. Use appropriate gauge wire and an inline fuse (not supplied) as close to the battery as possible.
- زميني ڪنيڪشن: گرائونڊ ڪيبل سان ڳنڍيو ampگاڏي جي چيسس جي صاف، غير رنگ ٿيل ڌاتو جي مٿاڇري تي لائفائر. هڪ مضبوط، گهٽ مزاحمتي ڪنيڪشن کي يقيني بڻايو.
- ريموٽ ٽرن آن: ريموٽ ٽرن آن تار کان ڳنڍيو amplifier to the remote output of your head unit. This will turn the ampتوهان جي آڊيو سسٽم سان لائفائر آن ۽ آف ڪريو.
- آڊيو ان پٽ: Connect your audio source (head unit) to the amplifier's input terminals. Use either the high-level inputs (speaker wire from head unit) or low-level inputs (RCA cables from head unit's pre-outs).
- اسپيڪر آئوٽ: پنھنجي اسپيڪر کي ڳنڍيو ampلائفائر جا اسپيڪر آئوٽ پُٽ ٽرمينل. هر اسپيڪر لاءِ صحيح پولارٽي (+ کان + ۽ - کان -) کي يقيني بڻايو.
آپريٽنگ هدايتون
شروعاتي پاور اپ
After all connections are made, turn on your vehicle's ignition and then your audio head unit. The ampلائفائر کي آن ٿيڻ گهرجي، جيڪو LED اشاري سان ظاهر ٿئي ٿو (جيڪڏهن موجود هجي).
حاصل ڪنٽرول ڪنٽرول
The variable gain control allows you to match the amplifier's input sensitivity to the output level of your head unit. Start with the gain control at its minimum setting. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the amplifier's gain control until you hear distortion, then back it off slightly until the sound is clear. Avoid setting the gain too high, as this can lead to distorted audio and potential damage to speakers or the ampوierيڪ زنده
سار سنڀال
The Legacy LA120 amplifier requires minimal maintenance. Regular checks can help ensure its longevity.
- صفائي: وقتي طور تي ٻاهرين حصي کي صاف ڪريو amplifier with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
- وينٽيليشن: Ensure that the heat sink fins are not obstructed by dust or other materials. Proper airflow is essential for cooling.
- ڪنيڪشن چيڪ: Occasionally check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
