The CDA-9884 head unit from Alpine, released early in 2008, has a steering wheel remote control input located in the rear of the unit to use the steering wheel controls to control the unit itself. The CDA-9884 can read WMA, MP3 and AAC file formats and is equipped with a bass engine designed to provide better control over high and low frequencies. To reverse settings back to the defaults a Defeat on/off button is located on the front of the device. A dedicated sub-woofer out allows for the control of the low frequency output from 0db to +15db. An optional auxiliary input can be used for a portable TV or DVD unit and iPod direct connection is available via a supplied cable. The CDA-9884 is also capable of accepting HD signals including multicast signals, as well as XM and Sirius satellite radio.
