• Ipo Sitẹrio: Connect the positive (+) and negative (-) terminals of your left speaker to the amplifier's + LEFT - terminals. Repeat for the right speaker using the + RIGHT - terminals. Ensure correct polarity.
• Bridged Mode (Mono): For higher power output to a single speaker (e.g., a subwoofer), connect the speaker's positive (+) terminal to the amplifier's + LEFT + terminal and the speaker's negative (-) terminal to the amplifier's - RIGHT - terminal. Refer to the ampAwọn pato lifier fun ikọlu ti o kere ju ni ipo afara (ni deede 4 ohms).

1. Lẹ́yìn tí gbogbo ìsopọ̀ bá ti wáyé, tún so ẹ̀rọ batiri tí kò ní agbára mọ́ ọkọ̀ náà pọ̀ mọ́.
2. Turn on your head unit. The POWER LED on the amplifier should illuminate green.
3. Ṣeto awọn amplifier's GAIN control to minimum (fully counter-clockwise).
4. Play a familiar piece of music at a moderate volume level on your head unit (around 75% of maximum volume).
5. Slowly increase the GAIN control on the amplifier until you hear distortion, then back it off slightly until the sound is clear. This sets the gain properly to match your head unit's output.

6.2 adakoja Eto

• EKUN: For full-range output, allowing all frequencies to pass through.
• LPF (Àlẹmọ Pass Kekere): Use for subwoofers. Set the FILTER switch to LPF and adjust the LPF knob (50Hz-250Hz) to cut off higher frequencies. A common starting point is 80Hz-100Hz.
• HPF (Àlẹmọ Pass giga): Use for full-range or component speakers to protect them from low frequencies. Set the FILTER switch to HPF and adjust the HPF knob (80Hz-3KHz) to cut off lower frequencies. A common starting point is 80Hz-100Hz.

6.3 Bass didn

The BASS BOOST switch provides an adjustable bass enhancement. Use this feature sparingly and adjust carefully to avoid distortion or speaker damage. Start at 0dB and increase gradually if desired.
