5. Installatie en installatie

Een correcte installatie is cruciaal voor optimale prestaties en veiligheid. Raadpleeg een professionele auto-audio-installateur als u over bepaalde stappen twijfelt.

5.1 Montagelocatie

Kies een montagelocatie die:

• Droog en vrij van vocht.
• Goed geventileerd, zodat de warmte kan worden afgevoerd.
• Secure, preventing movement during vehicle operation.
• Toegankelijk voor bedrading en aanpassingen.

5.2 bedradingsverbindingen

Refer to the installation diagram below for correct wiring. Ensure all connections are secure and properly insulated.

1. Power Connection (POWER): Connect a 6mm² (approx. 10 AWG) power cable from the vehicle's positive battery terminal to the amplifier's "POWER" terminal. Install a 30A fuse within 30cm (12 inches) of the battery.
2. Aardverbinding (GND): Connect a 6mm² (approx. 10 AWG) ground cable from the amplifier's "GND" terminal to a clean, unpainted metal point on the vehicle's chassis. Ensure a solid electrical connection.
3. Op afstand inschakelen (REM): Connect a 0.75mm² (approx. 18 AWG) remote wire from your head unit's remote output to the amplifier's "REM" terminal. This turns the amplifier aan en uit met uw hoofdeenheid.
4. Speaker Connection (SPEAKERS): Connect your subwoofer(s) to the "SPEAKERS" terminals using 2.5mm² (approx. 14 AWG) speaker wire. Ensure the total impedance of the connected subwoofers is 2 Ohms or higher. Observe correct polarity (+ to + and - to -).
5. Audio-ingang (INPUT):
   • RCA-ingang: Sluit RCA-kabels aan van de subwooferuitgang van uw autoradio naar de amplifier's "INPUT L" and "INPUT R" RCA jacks.
   • Hoge ingang: If your head unit does not have RCA outputs, use the high-level input. Connect the speaker outputs from your head unit to the "HIGH INPUT" terminals (+L/-L and +R/-R).

6. Gebruiksaanwijzing

Zodra de amplifier is installed and wired correctly, you can adjust its settings for optimal sound performance.

6.1 Eerste inschakeling

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): Deze controle komt overeen met de 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: Hiermee wordt de middenfrequentie voor de basversterking geselecteerd.
  • VERDIENEN: 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.

7. Onderhoud

The Stetsom IR 400.1 BASS ampDe filter vereist minimaal onderhoud. Volg deze richtlijnen om de levensduur te verlengen:

• Houd de ampDe versterker moet schoon en vrij van stof en vuil zijn. Gebruik een zachte, droge doek om hem schoon te maken.
• Zorg voor voldoende ventilatie rondom de ampversterker. Blokkeer de koelribben of ventilatieopeningen niet.
• Periodically check all wiring connections for tightness and corrosion. Loose connections can cause performance issues or damage.
• If the fuse blows, replace it only with a fuse of the same type and rating (30A). Using a fuse with a higher rating can lead to severe damage or fire.
