  • Controle de fase: Adjust the phase of individual channels to correct acoustic issues.
• Chave seletora de nível de entrada: Set the "INPUT LEVEL" switch on the unit to "LOW" for RCA inputs or "HI" for speaker-level inputs.
• Modo de ativação: Select the desired turn-on mode using the "TURN-ON MODE" switch:
  • REM: Uses a traditional remote turn-on wire from the head unit.
  • CC: Detects a DC offset on the speaker-level inputs to turn on.
  • ÁUDIO: Detects an audio signal on the speaker-level inputs to turn on.

Manutenção

The Infinity INFDSP4425 requires minimal maintenance.
