Соединения проводки
The INFDSP4425 features clearly labeled wire connections for straightforward installation.
- Мощность (PWR): Connect the main power wire to the vehicle's positive battery terminal, ensuring an inline fuse is installed close to the battery.
- Земля (земля): Подключите заземляющий провод к чистой, неокрашенной металлической поверхности на шасси автомобиля.
- Удаленный (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.
- Вход: The DSP accepts both RCA (low-level) and speaker-level (high-level) inputs. Connect your audio source to the appropriate input terminals.
- Выход: Connect the speaker outputs to your vehicle's speakers and the subwoofer pre-out to an external subwoofer ampпожизненнее.

Начальная конфигурация
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 webсайт.
Инструкция по эксплуатации
The primary operation of the INFDSP4425 involves using the DSP software to customize your audio settings.
- Программное обеспечение для цифровой обработки сигналов: Launch the DSP software on your connected computer. The interface provides controls for:
- Выравнивание: Adjust the 31-band equalizer for each channel to fine-tune the frequency response.
- Кроссоверы: Set high-pass, low-pass, and band-pass filters for each speaker to direct appropriate frequencies.
- Выравнивание времени: Adjust the delay for each speaker to ensure sound arrives at the listening position simultaneously.
- Gain Control: Independently adjust the output level for each channel.
- Фазовое управление: Adjust the phase of individual channels to correct acoustic issues.
- Переключатель уровня входного сигнала: Set the "INPUT LEVEL" switch on the unit to "LOW" for RCA inputs or "HI" for speaker-level inputs.
- Режим включения: Select the desired turn-on mode using the "TURN-ON MODE" switch:
- РЕМ: Uses a traditional remote turn-on wire from the head unit.
- ДК: Detects a DC offset on the speaker-level inputs to turn on.
- АУДИО: Detects an audio signal on the speaker-level inputs to turn on.
Обслуживание
The Infinity INFDSP4425 requires minimal maintenance.
- Уборка: Периодически протирайте устройство мягкой сухой тканью, чтобы удалить пыль. Не используйте едкие химикаты или абразивные чистящие средства.
- Вентиляция: Ensure that the mounting location allows for adequate airflow around the unit to prevent overheating.
- Соединения: Периодически проверяйте все соединения проводки, чтобы убедиться в их надежности и отсутствии коррозии.
