Электраправодныя злучэнні
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.
- Зямля (GND): Connect the ground wire to a clean, unpainted metal surface on the vehicle chassis.
- Дыстанцыйны (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.
- Увод: The DSP accepts both RCA (low-level) and speaker-level (high-level) inputs. Connect your audio source to the appropriate input terminals.
- выхад: Connect the speaker outputs to your vehicle's speakers and the subwoofer pre-out to an external subwoofer ampзадымнік.

Пачатковая канфігурацыя
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.
Інструкцыя па эксплуатацыі
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:
- Выраўноўванне: Adjust the 31-band equalizer for each channel to fine-tune the frequency response.
- кросоверы: Set high-pass, low-pass, and band-pass filters for each speaker to direct appropriate frequencies.
- Выраўноўванне часу: 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.
- Кантроль фазы: Adjust the phase of individual channels to correct acoustic issues.
- Input Level Switch: Set the "INPUT LEVEL" switch on the unit to "LOW" for RCA inputs or "HI" for speaker-level inputs.
- Рэжым уключэння: Select the desired turn-on mode using the "TURN-ON MODE" switch:
- REM: Uses a traditional remote turn-on wire from the head unit.
- DC: Detects a DC offset on the speaker-level inputs to turn on.
- АЎДЫЯ: Detects an audio signal on the speaker-level inputs to turn on.
