- Speaker Terminals (L+, L-, R+, R-): Connect to left and right speakers.
- Visok vnos: For connecting to head units without RCA outputs.
- Low Input (RCA): Za priklop glavnih enot z RCA predojačevalnimi izhodi.
- Nadzor ravni: Prilagodi vhodno občutljivost amplifier.
- Stikalo filtra: Selects between Full Range and Low Pass filter modes.
Namestitev in nastavitev
1. Montaža Amplifier
Choose a secure, dry location with adequate ventilation. Avoid mounting near heat sources or in direct sunlight. Use the provided mounting hardware to secure the amplifier.
2. Povezave ožičenja
Ensure the vehicle's battery is disconnected before making any wiring connections.
Napajalne povezave:
- B+ (Positive): Connect to the vehicle's positive battery terminal via a fuse (not included, recommended 15A-20A).
- B- (Ground): Connect to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
- R (Remote Turn-On): Priključite na daljinski izhod vaše glavne enote. Ta žica vklopi ampvklop in izklop sistema za odpravljanje težav z vašim stereo sistemom.
Avdio vhodne povezave:
Choose either High Input or Low Input, but not both simultaneously.
- Visok vnos: If your head unit does not have RCA outputs, connect the speaker outputs of your head unit to the High Input connector using the provided harness.
- Low Input (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit to the amplifier's Low Input jacks.
Priključki zvočnikov:
- Priključite zvočnike na amplifier's speaker terminals (L+, L-, R+, R-). Ensure correct polarity (+ to + and - to -).
- The amplifier supports a minimum speaker impedance of 4 ohms per channel.
Navodila za uporabo
Začetni vklop:
- After all connections are made and verified, reconnect the vehicle's battery.
- Vklopite glavno enoto. amplifier should power on, indicated by the "POWER" LED.
Prilagajanje nastavitev:
- Nadzor ravni: Start with the Level control at its minimum setting. Play a familiar audio track at a moderate volume from your head unit. Slowly increase the amplifier's Level control until you hear distortion, then back it off slightly. This sets the input sensitivity.
- Stikalo filtra:
- POLNO: For full-range speakers (e.g., coaxial speakers).
- NIZKI PREHOD: For subwoofers. This setting filters out high frequencies, allowing only low frequencies to pass through.
Vzdrževanje
- Obdrži ampČistilec naj bo čist in brez prahu in umazanije. Za čiščenje uporabite mehko, suho krpo.
- Zagotovite zadosten pretok zraka okoli amplifier za preprečevanje pregrevanja.
- Občasno preverite vse ožičene povezave glede tesnosti in korozije.
Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Ni napajanja/ni zvoka | Pregorela varovalka | Check and replace the fuse on the power line. |
| Ni napajanja/ni zvoka | Ohlapna napajalna ali ozemljitvena povezava | Verify all power (B+, B-, R) and ground connections are secure. |
| Ni napajanja/ni zvoka | Žica za daljinski vklop ni priključena ali je okvarjena | Ensure the remote wire is connected to the head unit's remote output and is receiving 12V when the head unit is on. |
| Izkrivljen zvok | Level control set too high | Zmanjšajte amplifier's Level control. |
| Izkrivljen zvok | Speaker wires shorted or incorrect impedance | Check speaker wiring for shorts and ensure speakers meet the amplifier's impedance requirements (4 ohms minimum). |
| No Sound from one channel | Faulty RCA cable or speaker wire | Check RCA and speaker connections for the affected channel. |
| Amplifier Pregreva | Nezadostno prezračevanje | Premestite amplifier to a better-ventilated area or clear obstructions. |
| Amplifier Pregreva | Impedanca zvočnika je prenizka | Ensure speakers meet the minimum impedance requirement. |
