Conexiones de cableado
The INFDSP4425 features clearly labeled wire connections for straightforward installation.
- Power (PWR): Connect the main power wire to the vehicle's positive battery terminal, ensuring an inline fuse is installed close to the battery.
- Tierra (GND): Connect the ground wire to a clean, unpainted metal surface on the vehicle chassis.
- Remoto (REM): Connect the remote turn-on wire to your head unit's remote output. Alternatively, the unit supports DC offset or audio signal sensing for automatic turn-on.
- Aporte: The DSP accepts both RCA (low-level) and speaker-level (high-level) inputs. Connect your audio source to the appropriate input terminals.
- Producción: Connect the speaker outputs to your vehicle's speakers and the subwoofer pre-out to an external subwoofer ampmás duradero.

Configuración inicial
After physical installation, the INFDSP4425 requires configuration using its dedicated DSP software. This software allows for precise tuning of equalization, crossovers, time alignment, and other audio parameters. Connect the unit to a computer via the USB port (labeled PC) and download the software from the official Harman websitio.
Instrucciones de funcionamiento
The primary operation of the INFDSP4425 involves using the DSP software to customize your audio settings.
- DSP Software: Launch the DSP software on your connected computer. The interface provides controls for:
- Igualdad: Adjust the 31-band equalizer for each channel to fine-tune the frequency response.
- Cruces: Set high-pass, low-pass, and band-pass filters for each speaker to direct appropriate frequencies.
- Alineación de tiempo: Adjust the delay for each speaker to ensure sound arrives at the listening position simultaneously.
- Control de ganancia: Independently adjust the output level for each channel.
- Control de fase: Adjust the phase of individual channels to correct acoustic issues.
- Interruptor de nivel de entrada: Set the "INPUT LEVEL" switch on the unit to "LOW" for RCA inputs or "HI" for speaker-level inputs.
- Modo de encendido: Select the desired turn-on mode using the "TURN-ON MODE" switch:
- MOVIMIENTO RÁPIDO DEL OJO: Uses a traditional remote turn-on wire from the head unit.
- CORRIENTE CONTINUA: Detects a DC offset on the speaker-level inputs to turn on.
- AUDIO: Detects an audio signal on the speaker-level inputs to turn on.
Mantenimiento
The Infinity INFDSP4425 requires minimal maintenance.
- Limpieza: Limpie la unidad periódicamente con un paño suave y seco para eliminar el polvo. No utilice productos químicos agresivos ni limpiadores abrasivos.
- Ventilación: Ensure that the mounting location allows for adequate airflow around the unit to prevent overheating.
