Sambungan kakuatan
- + 12V (Kakuatan): Connect directly to the positive terminal of the vehicle's battery using a fuse holder within 18 inches of the battery.
- GND (tanah): Sambungkeun kana permukaan logam chassis kendaraan anu bersih sareng teu acan dicét. Pastikeun sambunganna pageuh.
- REM (Jauh Hurungkeun): Sambungkeun ka kaluaran jauh unit sirah anjeun. Kawat ieu ngahurungkeun amplifier sareng mareuman stereo mobil anjeun.
Sambungan Input Audio
- RCA Inputs (Low-Level): Connect to the RCA pre-amp kaluaran unit sirah anjeun.
- Input Tingkat Tinggi: If your head unit does not have RCA outputs, use the high-level inputs by connecting them to your speaker wires.
Sambungan Kaluaran Speaker
- Stereo Mode (2-Channel): Connect one speaker to the left channel outputs (+ and -) and another speaker to the right channel outputs (+ and -).
- Bridged Mode (1-Channel Mono): For higher power output to a single subwoofer, bridge the amplifier. Connect the positive terminal of the speaker to the positive output of one channel and the negative terminal of the speaker to the negative output of the other channel (refer to specific bridging instructions on the amplifier or in a detailed wiring diagram). The LA978 offers 1200 Watts x 1 bridged output.
Parentah Operasi
Sakali dipasang, saluyukeun ampsetélan lampu pikeun kinerja sora anu optimal.
Variabel Input Level (Gain) kontrol
kontrol ieu cocog jeung amplifier's input sensitivity to the output of your head unit. Start with the gain control at minimum, then slowly increase it until you hear distortion, then back it off slightly. Do not use the gain control as a volume knob.
Variabel Hai / Lo Electronic kawin silang Network
Use the crossover controls to filter frequencies. A Low Pass Filter (LPF) allows only low frequencies to pass, ideal for subwoofers. A High Pass Filter (HPF) allows only high frequencies to pass, ideal for full-range speakers or tweeters. Adjust these settings to match your speakers' capabilities and desired sound.
Ngaronjatkeun Bass Ngaronjatkeun
This feature allows you to increase the bass output at a specific frequency. Use sparingly to avoid distortion and potential speaker damage. The amplifier also supports a Jauh Bass naekeun for convenient adjustment from the driver's seat (remote sold separately or included depending on package).
Indikator LED
- Daya ON LED: Illuminates nalika ampliifier nampi daya sareng tiasa dianggo sapertos biasana.
- Perlindungan LED: Illuminates nalika amplifier detects a fault (e.g., thermal overload, short circuit, low voltage). If this LED lights up, immediately turn off your audio system and troubleshoot the issue.
Pangropéa
- beberesih: Paké kaen lemes, garing pikeun ngabersihan ampjaba lifier urang. Ulah make bahan kimia kasar atawa cleaners abrasive.
- Ventilasi: Pastikeun yén amplifier's cooling fins are free from dust and obstructions to maintain proper airflow and prevent overheating.
- Sambungan: Pariksa sacara berkala sadaya sambungan daya, ground, sareng speaker pikeun mastikeun éta aman sareng bébas tina korosi.
