Low level (RCA) input signal is preferred for best performance. Typical
The adjustable crossover is used to filter out frequencies above 25Hz ~ 120Hz. Adjust it to where the BAK1500 sound output blends with the rest of the sound system.
The phase control compensates for delay between the BAK1500 output and the rest of the sound system. Begin with the phase control set to 0 degrees. If the sound is adequate from the normal listening position inside the vehicle, no further adjustment is necessary. If the sound is thin or lacking bass, adjust the phase control until the bass is full and punchy.
The input level control (LEVEL) is used to obtain the best possible match between the head unit audio output and the amplifier input. Begin by turning the input level control fully counterclockwise. Next, turn up the head unit volume control around 3/4 of the way up. Adjust the input level control clockwise until audible distortion is heard, then slightly counterclockwise to provide the best match.
The LED indicator illuminates green during normal operation.
