4.1 Conexións do panel traseiro
Image: Rear panel of the Genius G4B-5000.2K amplificador. Isto view shows the power input terminals (GND, REM, B+) on the left and the speaker output terminals (CH1/BRIDGE, CH2) on the right.
- POWER INPUT (GND, REM, B+): These terminals are for connecting the amplifier to the vehicle's electrical system. 'GND' is for ground, 'REM' is for the remote turn-on signal, and 'B+' is for the main positive battery connection.
- SPEAKER OUTPUT (CH1/BRIDGE, CH2): These terminals are for connecting your speakers. The amplifier supports 2-channel stereo output or can be bridged for a single, more powerful mono output.
4.2 Controis do panel frontal
Image: Front panel of the Genius G4B-5000.2K amplificador. Isto view displays the input RCA jacks, gain controls, subsonic filter, high-pass filter (HPF), low-pass filter (LPF), G-Bass frequency, G-Bass level, output RCA jacks, and remote port.
- INPUT (CH1, CH2): RCA jacks for connecting the audio signal from your head unit or pre-ampmáis vivo.
- GAÑA: Axusta a sensibilidade de entrada do amplifier to match the output of your head unit.
- SUBSONICO: A filter that removes extremely low frequencies below the audible range, protecting subwoofers and improving sound quality.
- HPF (filtro paso alto): Allows frequencies above the set point to pass through, typically used for full-range speakers. Adjustable from 30Hz - 300Hz.
- LPF (filtro paso baixo): Allows frequencies below the set point to pass through, typically used for subwoofers. Adjustable from 50Hz - 500Hz.
- G-BASS FREQ (Bass Boost Frequency): Selects the center frequency for the bass boost. Adjustable from 35Hz - 120Hz.
- G-BASS LEVEL (Bass Boost Level): Adjusts the intensity of the bass boost. Adjustable from 0 - 12dB.
- OUTPUT (CH1, CH2): RCA jacks for passing the audio signal to another amplifier nun multi-amp configuración.
- REMOTO: Port for connecting an optional remote bass level control.
- PROTECT/POWER Indicators: LEDs indicating the amplifier's status. 'POWER' illuminates when the amplifier is on. 'PROTECT' illuminates when the amplifier enters protection mode due to a fault.
5. Configuración e instalación
Unha instalación axeitada é fundamental para o rendemento e a seguridade do seu amplifier. If you are unsure about any step, consult a professional installer.
5.1 Localización de montaxe
- Escolle un lugar seco e ben ventilado, lonxe da luz solar directa e de fontes de calor.
- Asegúrese de que o fluxo de aire quente arredor do ampaletas de arrefriamento do transformador.
- Monte o amplifier securely to a solid surface using the provided mounting hardware.
- Avoid mounting on carpet or other materials that could obstruct airflow.
5.2 Conexións de cableado
Always disconnect the vehicle's negative battery terminal before making any electrical connections.
- Cable de alimentación (B+): Run a heavy-gauge power cable (e.g., 4-gauge or larger, depending on total system power) directly from the positive terminal of the vehicle's battery to the amplifier's 'B+' terminal. Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Cable de terra (GND): Connect a heavy-gauge ground cable (same gauge as power wire) from the amplifier's 'GND' terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Cable de activación remota (REM): Connect a smaller gauge wire (e.g., 18-gauge) from the head unit's remote turn-on output to the amplifier's 'REM' terminal. This wire turns the ampacender e apagar o activador coa unidade principal.
- Cables de entrada RCA: Conecte os cables RCA da toma de corrente da unidade principalamp saídas ao amplifier's 'INPUT' RCA jacks.
- Fíos dos altofalantes: Connect your speakers to the 'SPEAKER OUTPUT' terminals. Ensure correct polarity (+ to + and - to -) for each speaker. For bridged mode, refer to the diagram on the amplifier or consult a professional.
6. Instrucións de funcionamento
Unha vez que amplifier is installed and all connections are secure, you can power on your system and adjust the settings.
- Encendido inicial: Reconnect the vehicle's negative battery terminal. Turn on your head unit. The 'POWER' indicator on the amplifier should illuminate.
- Axuste de ganancia: Comeza co amplifier's GAIN control set to minimum. Play a familiar piece of music at a moderate volume on your head unit (about 75% of maximum). Slowly increase the GAIN control on the amplifier until you hear slight distortion, then back it off slightly. This matches the ampa sensibilidade de entrada do adaptador á saída da unidade principal.
- Filter Settings (HPF/LPF):
- For Full-Range Speakers: Set the HPF to a suitable frequency (e.g., 80Hz-120Hz) to remove low bass frequencies that small speakers cannot reproduce effectively.
- For Subwoofers (Bridged Mode): Set the LPF to a suitable frequency (e.g., 80Hz-100Hz) to allow only low frequencies to pass to the subwoofer. The SUBSONIC filter can be used to cut frequencies below the subwoofer's resonant frequency (e.g., 20Hz-30Hz).
- Bass Boost (G-BASS): Adjust the G-BASS FREQ and G-BASS LEVEL controls to enhance bass response to your preference. Use sparingly to avoid distortion and speaker damage.
7. Mantemento
The Genius G4B-5000.2K ampO lificador require un mantemento mínimo.
- Limpeza: Limpar periodicamente o ampo exterior do lifador cun pano suave e seco. Non empregue produtos químicos agresivos nin produtos de limpeza abrasivos.
