6. Cyfarwyddiadau Gweithredu

Unwaith y bydd y amplifier is installed and wired correctly, you can adjust its settings for optimal sound performance.

6.1 Pŵer Cychwynnol

After all connections are made, reconnect the vehicle's battery. Turn on your head unit. The amplifier should power on, indicated by an illuminated LED (if present).

6.2 Adjusting Audio Controls

The Stetsom IR 400.1 BASS features several adjustable controls on its rear panel:

• INPUT LEVEL (MIN/MAX): Mae'r rheolaeth hon yn cyfateb i'r amplifier's input sensitivity to the output level of your head unit. Start with the level at minimum, then slowly increase it until you hear distortion, then back off slightly.
• CROSSOVER (L.P.F. 35Hz ~ 250Hz): The Low Pass Filter (LPF) allows frequencies below the set point to pass through to the subwoofer. Adjust this to blend the subwoofer's output seamlessly with your main speakers. A common starting point is 80Hz-100Hz.
• CROSSOVER (H.P.F. 5Hz ~ 35Hz): The High Pass Filter (HPF) allows frequencies above the set point to pass. For subwoofers, this is typically used to filter out extremely low, inaudible frequencies that can waste amplifier power and potentially damage the subwoofer. Set it to the lowest useful frequency, often around 5Hz-10Hz.
• BASS BOOST (FREQ 35Hz ~ 60Hz, GAIN 0dB ~ +15dB): This control allows you to boost specific bass frequencies.
  • FREQ: Selects the center frequency for the bass boost.
  • ENILL: Adjusts the amount of boost applied to the selected frequency. Use sparingly to avoid distortion and potential damage to your subwoofer.

Recommendation: Make small adjustments and listen carefully to the sound. It is often best to set the gain and crossover points with test tones or familiar music to achieve the desired sound quality.
