• Input Level (HI/LO): Selects between high-level (speaker-level) or low-level (RCA) input signals.
• Gain Control (MIN/MAX): Saluyukeun sensitipitas input tina amplifier to match the output of your head unit. Start with minimum gain and slowly increase until desired volume is achieved without distortion.
• Crossover (X-OVER - HPF/LPF/FULL): Selects the type of filter for the output.
  • HPF (Saringan High-Pass): Allows frequencies above the set point to pass through, ideal for full-range speakers.
  • LPF (Low-Pass Filter): Allows frequencies below the set point to pass through, ideal for subwoofers.
  • FULL: Allows all frequencies to pass through, bypassing the crossover.
• Frékuénsi (FREQ): Adjusts the cutoff frequency for the HPF or LPF, typically ranging from 32Hz to 320Hz.
• Bass Boost (0dB/12dB): Provides an adjustable bass boost at 45Hz to enhance low-frequency output.
• Fase (0°/180°): Adjusts the phase of the output signal, useful for optimizing bass response with subwoofers.
• Turn-On Mode (DC/REM): Selects how the amplifier hurung.
  • DC: Detects a DC offset on the high-level inputs to turn on the amppangagung.
  • REM: Uses a dedicated remote turn-on wire from the head unit.
