- If installing a subwoofer, the front and rear outputs will default to a 100Hz high pass filter to keep the low frequency signals out. If a subwoofer is not being installed, change the front and rear crossover points down to 20Hz for a full range signal, or to the lowest frequency the speakers will play down to.

- Selecting High Pass and Low Pass will provide one crossover frequency adjustment. Selecting Band Pass will provide two crossover frequency adjustments, one for low pass, and one for high pass.

Inputs/Levels

SETUP INSTRUCTIONS CROSSOVER ADJUST BLUETOOTH CONNECTION EQUALIZER ADJUST CONFIGURATION DELAY ADJUST OUTPUTS INPUT/LEVELS Chime Volume Volume: 3 Low Medium High The Chime Volume control is provided to prevent warning tones from being overly loud. Clipping Level Off On Level: 5 Soft Demo Hard The AX-DSP can detect clipping of the audio signals and reduce the level for a period of time to prevent damage to the speakers. Amp Turn On Turn On Delay: 6 0 Seconds 10 Signal Sense Always On The AMP ON line can be turned on whenever accessory power is on, or only when a signal is detected from the radio. Subwoofer Input Front + Rear Subwoofer The Subwoofer output can be driven from the sum of the Front and Rear inputs, or it can be from the Subwoofer input only.

• Chime Volume - Allows the chime volume to be adjusted up or down.
• Clipping Level - Use this feature to protect sensitive speakers like tweeters from being driven past their capabilities. If the output signal of the interface clips the audio will be reduced by 20dB. Turning down the stereo will allow the audio to come back at a normal level. The sensitivity of this feature can be adjusted to the listening preference of the user.

- Amp Turn On

• Signal Sense - Will turn the amp(s) on when an audio signal is detected, and keep on for 10 seconds after the last signal. This ensures the amp(s) won't shut off between tracks.
• Always On - Will keep the amp(s) on as long as the ignition is cycled on.
• Turn on Delay - Can be used to delay audio output to avoid turn-on pops.

- Subwoofer Input - Select Front + Rear
