וויירינג קאַנעקשאַנז
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.
- ערד (GND): Connect the ground wire to a clean, unpainted metal surface on the vehicle chassis.
- ווײַט (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.
- אַרייַנשרייַב: The DSP accepts both RCA (low-level) and speaker-level (high-level) inputs. Connect your audio source to the appropriate input terminals.
- רעזולטאַט: Connect the speaker outputs to your vehicle's speakers and the subwoofer pre-out to an external subwoofer ampליפער.

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:
- יקוואַליזיישאַן: Adjust the 31-band equalizer for each channel to fine-tune the frequency response.
- קראָססאָווערס: Set high-pass, low-pass, and band-pass filters for each speaker to direct appropriate frequencies.
- צייט אַליינמאַנט: Adjust the delay for each speaker to ensure sound arrives at the listening position simultaneously.
- געווינען קאָנטראָל: Independently adjust the output level for each channel.
- פאַסע קאָנטראָל: Adjust the phase of individual channels to correct acoustic issues.
- אינפוט לעוועל סוויטש: Set the "INPUT LEVEL" switch on the unit to "LOW" for RCA inputs or "HI" for speaker-level inputs.
- קער אויף מאָדע: 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.
- אַודיאָ: Detects an audio signal on the speaker-level inputs to turn on.
