• High Pass Filter (HPF): speaker level and preamp (front and rear) outputs have a selectable crossover (HPF); off (default), 80Hz, 120Hz, or 160Hz
• Loudness: on/off
• Defeat On/Off: reset the unit to its factory default bass, treble, loudness, and HPF settings by turning on the Defeat function

Subwoofer Pre-out: In addition to the front and rear preamp outputs, the CDE-9881 has a dedicated subwoofer output with a variable level of 0 to +15.

Interrupt Feature: When a device having the interrupt feature (such as a cellular telephone) is connected to the receiver, the audio signal will be automatically muted whenever the interrupt signal is received from that device. The supplied wiring harness contains a pink/black Interrupt lead that needs to be connected to the device's interrupt signal connection.

Dimmer: This unit is equipped with an illumination lead. When the unit's dimmer mode has been set to Auto and the illumination lead has been connected to your vehicle's headlight circuit, the illumination will dim to a fixed, preset level whenever the headlights are turned on. If preferred, you may choose the Manual dimmer mode setting, so the button illumination is dim at all times.

Angle Mounting: Alpine recommends mounting the CDE-9881 no more that 35? above horizontal.

Power IC Off: When an external amplifier is powering all the speakers in the system, you can turn the internal amp off, which will improve the sound quality.

Wireless Remote Ready: A wireless remote control can be added to control the CDE-9881. Both the RUE-4202 (item number 500RUE4202) and RUE-4190 (item number 500RUE4190) remotes are compatible. The remote control sensor is on the upper right corner of the faceplate.
