Öryggisupplýsingar
Mikilvægar öryggisleiðbeiningar:
- Aftengdu alltaf neikvæða pól rafgeymis ökutækisins áður en uppsetning hefst.
- Tryggðu rétta jarðtengingu til að koma í veg fyrir rafmagnshættu.
- Notið viðeigandi raflögn fyrir tengingu við aflgjafa og hátalara til að koma í veg fyrir ofhitnun og skemmdir.
- Settu upp amplifier securely in a well-ventilated area, away from moisture and direct sunlight.
- Ekki stjórna amplifier if it has been exposed to water or sustained physical damage.
- Leitaðu aðstoðar fagfólks ef þú ert óviss um einhver uppsetningarskref.
Uppsetning og uppsetning
Rétt uppsetning er mikilvæg fyrir afköst og öryggi amplifier. Refer to the diagrams below for connection details.
Uppsetning á Amplíflegri
Choose a mounting location that is dry, well-ventilated, and secure. Avoid mounting on carpet or in enclosed spaces that restrict airflow. Ensure sufficient space around the amplyftara fyrir hitaleiðni.

Rafmagnstengingar
- +12V (Afl): Tengdu beint við jákvæða pól rafgeymis ökutækisins með öryggishaldara innan við 18 cm frá rafgeyminum.
- GND (jörð): Tengdu við hreint, ómálað málmflöt á undirvagni ökutækisins. Gakktu úr skugga um trausta tengingu.
- REM (fjarstýrð kveiking): Tengdu við fjarstýringarútgang höfuðeiningarinnar. Þessi vír kveikir á ampKveiktu og slökktu á hátalaranum með bílstereóinu þínu.
Hljóðinntakstengingar
- RCA Inputs (Low-Level): Tengist við RCA forstillingunaamp útgangar höfuðeiningarinnar.
- Inntak á háu stigi: If your head unit does not have RCA outputs, use the high-level inputs by connecting them to your speaker wires.
Útgangstengingar hátalara
- 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.
Notkunarleiðbeiningar

Stýring á breytilegu inntaksstigi (Gain).
Þessi stjórn passar við 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.
Breytilegt Hi/Lo rafrænt krossnet
Use the crossover controls to filter frequencies. A Lágstreymissía (LPF) allows only low frequencies to pass, ideal for subwoofers. A Hápassasía (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.
Breytilegur Bass Boost
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 Fjarstýrð bassahækkun for convenient adjustment from the driver's seat (remote sold separately or included depending on package).
LED Vísar
- Power ON LED: Lýsir þegar ampRafmagnsgjafinn fær rafmagn og virkar eðlilega.
- Vörn LED: Lýsir þegar 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.
Viðhald
- Þrif: Notaðu mjúkan, þurran klút til að þrífa ampYtra byrði lyftarans. Notið ekki sterk efni eða slípiefni.
- Loftræsting: Gakktu úr skugga um að amplifier's cooling fins are free from dust and obstructions to maintain proper airflow and prevent overheating.
- Tengingar: Athugið reglulega allar tengingar við aflgjafa, jarðtengingar og hátalara til að tryggja að þær séu öruggar og lausar við tæringu.
Úrræðaleit
Ef þú lendir í vandræðum með þinn ampLifier, vísaðu til eftirfarandi algengra vandamála og lausna:
| Vandamál | Möguleg orsök | Lausn |
|---|---|---|
| Enginn rafmagn (slökkt á aflgjafa) | Sprungið öryggi, laus vír fyrir aflgjafa/jarðtengingu/fjarstýringu, bilaður útgangur á fjarstýringu höfuðeiningar. | Check fuse, verify all power connections, test remote wire for 12V. |
| Verndunar-LED kveikt | Short circuit in speaker wiring, amplifier overheating, low voltage. | Check speaker wires for shorts, ensure proper ventilation, verify battery voltage. Allow amplyftara til að kólna. |
| Ekkert hljóðúttak | Loose RCA cables, incorrect gain setting, speaker wires disconnected, head unit settings. | Check all audio connections, adjust gain, verify speaker connections, check head unit output. |
| Bjagað hljóð | Of hátt stillt á styrk, rangar stillingar á krossleiðsluvídd, skemmdir á hátalurum, léleg jarðtenging. | Reduce gain, adjust crossover, inspect speakers, ensure solid ground connection. |
