Blackout Display Mode: When the Blackout mode is activated, the display turns off to reduce power consumption. The additional power made available by turning off the display helps enhance sound quality.

Bass Engine: Bass Engine functions provide control over your system, so you can tailor the sound to your personal tastes. Bass Engine includes the following functions:

• Bass Center Frequency Control: To tailor bass response to your preference, you may select the bass control's center frequency. You may select from the following center frequencies: 60Hz, 80Hz, 100Hz, or 200Hz.
• Bass Width Control: You may choose from four band width (Q-Factor) settings for the bass control; the bass control can be set to affect a wide or narrow band of frequencies.
• Bass Type: You may choose from the following Bass Type settings: Type 1, Type 2, or Type 3. Type 1 will sound best if you have a subwoofer in your system. Use Type 2 or Type 3 if you are using small diameter speakers.
• Treble Center Frequency Control: To tailor treble response to your preference, you may select the treble control's center frequency. You may select from the following center frequencies: 10kHz, 12.5kHz, 15kHz, or 17.5kHz.

MX (MediaXpander): The CDA-9827 features the MediaXpander function, which is offered on Bass Engine Pro, Bass Engine Plus, and some Bass Engine models. The MediaXpander function makes vocals or instruments sound distinct by restoring sound quality typically lost during recording or transmission; this function helps restore audio information that becomes obscured when audio is compressed. The MX function can be applied to all sources, except AM radio. There are three expansion modes for each internal source (CD, FM, MP3/WMA/XM), and each source can have its own setting. There are only one or two expansion modes available for external sources.

MP3/WMA Playback: This unit can play CD-ROM, CD-R, and CD-RW discs containing MP3/WMA files recorded using the ISO 9660 Level 1 or Level 2 formats. MP3 files with constant and variable bit rates from 8 kbps to 320 kbps and WMA files with constant and variable bit rates from 32 kbps to 192 kbps are supported. Discs recorded using Joliet or other ISSO 9660 compliant formats can be played, but file and folder names will not be displayed correctly. CD-ROM XA, Mixed Mode CD, Enhanced CD (CD-Extra) and multi-session recordings are supported, but recordings made using Track At Once or packet writing cannot be correctly played back. Discs containing both standard CD audio and MP3/WMA data can be played; the unit may be set to play only the CD audio tracks or both types of tracks. ID3 tag v1 and v2 are supported; track title, artist name and album name ID3 tag data can be displayed.

Disc and Station Titling: Titles of up to 8 characters in length may be entered for up to 18 radio stations and 18 CDs.

XM Radio Ready: An optional XM Satellite Radio tuner may be connected to, and controlled by, this unit. The optional tuner, along with an antenna and subscription, allows you to receive XM Satellite Radio. XM Satellite Radio programming features up to 100 channels of digital-quality music, news, talk, sports, entertainment, and children's programming.

Auxiliary Input Ready: With the addition of the optional KCA-121B Ai-NET/RCA interface cable, the KCA-801B auxiliary input adapter, or the KCA-410C Versatile-Link Terminal, the audio from an auxiliary source can be played through this unit. When the KCA-121B interface cable is used, a CD changer cannot be connected to the head unit; the KCA-801B auxiliary input adapter allows you to connect an auxiliary source and an Ai-NET changer to the head unit. The KCA-410C Versatile-Link Terminal allows you to feed audio from up to two auxiliary sources and two Ai-NET CD changers to the head unit.

MobileHub Link: Using the MobileHub Link, you can connect an optional Junction Box and a Nokia 6310i tri-band GSM cellular phone, allowing you to control the incoming and outgoing calls from the head unit. 

Power Off: When an external amplifier is connected and the built-in amplifier is not used, removing power from the built-in amplifier will improve the sound quality.
