4. Opsætning og installation
4.1 Sikkerhedsforanstaltninger
- Disconnect the vehicle's battery before beginning any installation.
- Sørg for korrekt jording for at forhindre elektriske problemer.
- Brug passende ledninger til strøm-, jord- og højttalertilslutninger.
- Monter amplifier securely in a well-ventilated area, away from heat sources and moisture.
4.2 Ledningsforbindelser
The LC-4.800 offers flexible input options for both line-level (RCA) and speaker-level signals. Refer to Figure 3.4 for a visual guide to the connection panel.
- Strømtilslutning: Connect the +12V terminal to the vehicle's positive battery terminal via an appropriate fuse (not supplied).
- Jordforbindelse: Connect the Ground terminal to a clean, bare metal chassis point in the vehicle.
- Fjerntænding: Connect the Remote terminal to the head unit's remote output or use the GTO™ Signal Sense feature.
- Indgangssignaler:
- Line-Level Inputs (RCA): Connect your head unit's RCA outputs to the Front/Left and Rear/Right RCA inputs on the amplivligere.
- Højttalerniveauindgange: For factory stereos, connect the vehicle's speaker wires directly to the Speaker Level Inputs. The amplifier can sum signals if needed.
- Højttalerudgange: Connect your speakers to the Speaker Outputs, observing correct polarity. The amplifier supports 4-channel stereo or 2-channel bridged configurations.
- Optional ACR-1 Remote: If using, connect the ACR-1 remote to the dedicated Remote Level Control port.
Note: For optimal performance and to prevent distortion, it is recommended to use wire ferrules on speaker terminals for a cleaner and more secure connection.
5. Betjening af Amplivligere
5.1 Initial Power-Up and Gain Setting
After all connections are made, reconnect the vehicle's battery. The amplifier should power on. The MILC™ (Maximum Input Level Control) LEDs are crucial for setting proper gain levels.
- Turn your head unit volume up to about 75% of its maximum.
- Slowly increase the gain controls on the LC-4.800 for each channel until the corresponding MILC™ LED just begins to flicker or illuminate.
- Once the LED flickers, back off the gain slightly until the LED is off. This indicates the maximum clean input signal level, preventing clipping and distortion.
Vigtig: Setting gains correctly is vital for sound quality and amplifier longevity. The MILC™ LEDs provide an accurate visual indicator of clipping.
5.2 Crossover Adjustments
The LC-4.800 features adjustable crossover networks to optimize sound for your specific speakers.
- Højpasfilter (HPF): Used for full-range speakers to prevent low frequencies from reaching them, improving clarity and power handling. Adjust the frequency knob to the desired cutoff.
- Lavpasfilter (LPF): Used for subwoofers to allow only low frequencies to pass through. Adjust the frequency knob to the desired cutoff.
- Båndpasfilter (BPF): Allows a specific range of frequencies to pass through, useful for certain mid-range speaker setups.
Experiment with these settings to achieve the best sound balance for your system. Consult your speaker specifications for recommended crossover points.
5.3 AccuBASS™ Control
The AccuBASS™ circuit compensates for factory stereo bass roll-off. Adjust the AccuBASS™ threshold and level controls to restore and enhance bass response without distortion.
6. Vedligeholdelse
The AudioControl LC-4.800 is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:
- Rensning: Rengør med jævne mellemrum ampRengør ydersiden af apparatet med en blød, tør klud. Undgå at bruge skrappe kemikalier eller slibende rengøringsmidler.
- Ventilation: Sørg for amplifier's heat sinks are free from obstructions to allow for proper airflow and cooling. Do not cover the amplivligere.
- Forbindelser: Occasionally check all wiring connections (power, ground, remote, inputs, outputs) to ensure they remain secure and free from corrosion. Loose connections can lead to performance issues or damage.
- Sikringer: De amplifier uses external fuses (40A x 2). If a fuse blows, replace it only with a fuse of the same type and rating. Never use a higher-rated fuse.
