- 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.
- ગ્રાઉન્ડ કનેક્શન (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.
- રિમોટ ટર્ન-ઓન (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 ampતમારા હેડ યુનિટ સાથે લાઇફાયર ચાલુ અને બંધ કરો.
- 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 -).
- Audio Input (INPUT):
- RCA ઇનપુટ: Connect RCA cables from your head unit's subwoofer output to the amplifier's "INPUT L" and "INPUT R" RCA jacks.
- ઉચ્ચ ઇનપુટ: 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).

એકવાર આ amplifier is installed and wired correctly, you can adjust its settings for optimal sound performance.
૫.૧ પ્રારંભિક પાવર-અપ
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): આ નિયંત્રણ સાથે મેળ ખાય છે 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.
- વારંવાર Selects the center frequency for the bass boost.
- લાભ: 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. જાળવણી
The Stetsom IR 400.1 BASS ampલાઇફાયર્સને ઓછામાં ઓછી જાળવણીની જરૂર પડે છે. તેના લાંબા સમય સુધી ઉપયોગ માટે આ માર્ગદર્શિકા અનુસરો:
- રાખો amplifier clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- આસપાસ પર્યાપ્ત વેન્ટિલેશનની ખાતરી કરો amplifier. Do not block cooling fins or vents.
- 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.
