Упатства за работа
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:
- Изедначување: Adjust the 31-band equalizer for each channel to fine-tune the frequency response.
- Кросовери: Set high-pass, low-pass, and band-pass filters for each speaker to direct appropriate frequencies.
- Порамнување на времето: Adjust the delay for each speaker to ensure sound arrives at the listening position simultaneously.
- Здобијат со контрола: Independently adjust the output level for each channel.
- Контрола на фазата: Adjust the phase of individual channels to correct acoustic issues.
- Прекинувач за влезно ниво: Set the "INPUT LEVEL" switch on the unit to "LOW" for RCA inputs or "HI" for speaker-level inputs.
- Режим на вклучување: Select the desired turn-on mode using the "TURN-ON MODE" switch:
- РЕМ: Uses a traditional remote turn-on wire from the head unit.
- DC: 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.
