- Dimensions: 14.96''(L) x 2.24''(H) x 8.81''(W)
- Ensure at least 2 inches of clearance around the amppenguat untuk pelesapan haba yang betul.
2. Sambungan Pendawaian
Refer to the diagrams below for proper wiring. Incorrect wiring can damage the amplifier or vehicle electrical system.
Imej: Terperinci views of the Lanzar HTG447 amplifier's front and rear panels, illustrating input and output connections, including RCA, gain controls, crossover settings, power input, fuse, and speaker outputs.
Sambungan Kuasa:
- +12V (BATT): Connect directly to the positive terminal of the vehicle's battery using a suitable gauge power cable (e.g., 4-gauge). Install an in-line fuse holder within 18 inches of the battery.
- GND (Tanah): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid electrical connection. Use the same gauge wire as the +12V connection.
- REM (Jauh): Connect to the remote turn-on lead from your head unit. This wire turns the amplifier on and off with the head unit.
Audio Input (RCA) Connections:
- Sambungkan kabel RCA daripada pra-unit kepala andaamp output kepada amplifier's RCA inputs (1CH/2CH and 3CH/4CH).
- The amplifier also features Line Outs for Left and Right Channels, allowing connection to additional amppenyelamat.
Sambungan Output Pembesar Suara:
- Sambungkan pembesar suara anda ke amplifier's speaker terminals. Observe correct polarity (+ to + and - to -).
- For 4-channel stereo operation, connect one speaker per channel.
- For bridged operation (2-channel), connect speakers across the designated bridged terminals (e.g., 1CH+ and 2CH- for one bridged channel). Refer to the diagram on the amplebih hidup.
- The amplifier is 2 Ohm stereo stable. Ensure speaker impedance matches the ampkeupayaan liifier.
Arahan Operasi
Menyelaraskan Kawalan
The Lanzar HTG447 features several adjustable controls to fine-tune your audio system. These controls are located on the front panel of the amplebih hidup.
- Kawalan GAIN: Melaraskan sensitiviti input bagi amplifier to match the output level of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- X-OVER (Crossover) Control:
- PENUH: Full range audio output.
- HPF (Penapis Lulus Tinggi): Allows frequencies above the set point to pass through. Useful for full-range speakers to prevent low bass distortion. Adjustable up to 80KHz.
- LPF (Penapis Lulus Rendah): Allows frequencies below the set point to pass through. Essential for subwoofers. Adjustable from 50Hz-250Hz.
- DASAR ASAS: Provides an adjustable bass enhancement at a specific frequency. Use sparingly to avoid distortion and potential speaker damage.
Nota: Always make small adjustments and listen carefully to the audio output to prevent damage to speakers or the amplebih hidup.
Penyelenggaraan
- Simpan ampPastikan penghawa dingin bersih dan bebas daripada habuk dan serpihan. Gunakan kain lembut dan kering untuk membersihkan.
- Pastikan bukaan pengudaraan tidak terhalang.
- Periksa semua sambungan pendawaian secara berkala untuk kesesakan dan kakisan.
- If a fuse blows, replace it only with a fuse of the same type and rating (20A). Using an incorrect fuse can cause serious damage.
Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| No Power (Power LED Off) | Fius putus, sambungan kuasa/pembumian lemah, tiada isyarat hidupkan jauh. | Check fuses (amplifier and in-line). Verify +12V, GND, and REM connections. Ensure head unit is on. |
| LED Perlindungan Dihidupkan | Overheating, speaker short circuit, impedance too low. | Check for proper ventilation. Inspect speaker wiring for shorts. Verify speaker impedance is within limits (2 Ohm stable). |
| Tiada Output Audio | RCA cables disconnected, gain too low, speaker wires disconnected. | Check RCA connections from head unit. Adjust gain control. Verify speaker wiring. |
| Bunyi Herot | Gain set too high, improper crossover settings, poor quality audio source. | Reduce gain. Adjust LPF/HPF settings. Ensure audio source is clean. |
