5. Configuración e instalación

Unha instalación axeitada é fundamental para un rendemento e unha seguridade óptimos. Se tes algunha dúbida sobre calquera parte do proceso de instalación, consulta cun instalador profesional de audio para automóbiles.

5.1 Localización de montaxe

Escolla unha localización de montaxe que:

• Provides sufficient air circulation around the amplifier para refrixeración.
• Is protected from direct sunlight, moisture, and excessive vibration.
• Allows for secure attachment to a solid surface.
• Is away from fuel lines, brake lines, and electrical wiring harnesses.

Common mounting locations include under a seat, in the trunk, or behind a panel.

5.2 Conexións de cableado

Refer to the diagrams below for proper wiring connections. Ensure all connections are secure and insulated.

5.2.1 Power Connection (BATT+)

• Run a heavy gauge power cable (e.g., 8 AWG or larger for 1000W) directly from the positive terminal of the vehicle's battery to the BATT+ terminal on the ampmáis vivo.
• Install an in-line fuse holder with a fuse (appropriate amperage, typically 40-60A for a 1000W amplifier) within 18 inches (45 cm) of the battery.

5.2.2 Ground Connection (GND)

• Connect a heavy gauge ground cable (same gauge as power cable) from the GND terminal on the amplificador a unha superficie metálica limpa e sen pintar do chasis do vehículo.
• Ensure the ground point is free of paint, rust, or dirt for a good electrical connection. The cable length should be as short as possible, ideally less than 3 feet (1 meter).

5.2.3 Remote Turn-On Connection (REMOTE)

• Connect a remote turn-on wire (typically 18 AWG) from the REMOTE terminal on the amplifier to the remote output of your head unit.
• Este fío sinala o ampactivar o adaptador cando a unidade principal estea acendida.

5.2.4 Conexións de saída de altofalantes

• Conecta os teus altofalantes ao amplifier's speaker output terminals. The AT804S is a 4-channel ampmáis vivo.
• Ensure correct polarity (+ to + and - to -) for all speakers.
• O amplifier is 2 Ohm stable, allowing for various speaker configurations. Refer to the diagram for stereo and bridged (mono) wiring options.
• For bridged mode, connect the positive lead of the speaker to the CH1+ terminal and the negative lead to the CH2- terminal for one bridged pair. Repeat for CH3+ and CH4- for the second bridged pair.

5.2.5 Conexións de entrada RCA

• Connect RCA cables from the pre-out outputs of your head unit to the RCA input jacks on the amplifier (CH1/2 INPUT and CH3/4 INPUT).
• If your head unit does not have RCA outputs, the amplifier also supports speaker level inputs.

6. Instrucións de funcionamento

Unha vez que amplifier is installed, follow these steps for initial setup and operation.

6.1 Encendido inicial

• After all connections are made and verified, reconnect the vehicle's negative battery terminal.
• Acenda a unidade principal. O amplifier's POWER LED should illuminate, indicating it is receiving power and is operational. If the PROTECTION LED illuminates, refer to the troubleshooting section.

6.2 Gain Adjustment (Input Level)

• Set the head unit volume to about 75% of its maximum level.
• Aumentar lentamente o amplifier's GAIN control (Input Gain Control) until you hear slight distortion, then back it off slightly until the sound is clear.
• Este control coincide co amplifier's input sensitivity to the output of your head unit and is not a volume control.

6.3 Axustes de crossover

The AT804S features both high-pass and low-pass crossovers to optimize sound for different speakers.

• High Pass Crossover (HPF): Fixed at 200Hz. Use this for full-range speakers to prevent them from playing very low bass frequencies, which can cause distortion and damage.
• Filtro de paso baixo (LPF): This control allows you to set the upper frequency limit for speakers connected to the low-pass channels (typically for subwoofers). Adjust this to allow only frequencies below the set point to pass through. The specific frequency range is continuously variable.
• Adjust the crossover points to blend the sound between your speakers and any subwoofers.

6.4 Control remoto do subwoofer

If a remote subwoofer level control is connected, you can adjust the bass output level from your listening position. This control typically only affects the channels configured for low-pass output.
