5.2-rasm: orqa view of the Stetsom IR 400.1 BASS amplifier, displaying the Bass Boost, Crossover, Input Level controls, RCA inputs, High Input terminals, and an integrated wiring diagram.
- 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.
- Yerga ulanish (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.
- Masofadan yoqish (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 ampbosh blokingiz bilan ko'targichni yoqing va o'chiring.
- 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 Kirish (KIRISH):
- RCA kiritish: RCA kabellarini bosh qurilmangizning sabvufer chiqishidan ulang amplifier's "INPUT L" and "INPUT R" RCA jacks.
- Yuqori kirish: 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. Foydalanish bo'yicha ko'rsatmalar
Bir marta amplifier is installed and wired correctly, you can adjust its settings for optimal sound performance.
6.1 Dastlabki quvvatlanish
Barcha ulanishlar amalga oshirilgandan so'ng, transport vositasining batareyasini qayta ulang. Bosh blokingizni yoqing. 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): Bu nazorat mos keladi 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.
- Tez -tez: Selects the center frequency for the bass boost.
- GA: 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.
