Graphic Motion Analyzer: This unit is equipped with a sensor that measures the forces of gravity on the vehicle. This sensor enables the receiver to calculate G-forces during acceleration, braking, and cornering. The G-Analyzer also has a stop watch that can be automatically started when forward or reverse G-forces are detected. Setup and calibration for acceleration and braking must be performed before using the G-Analyzer. The Graphic Motion Analyzer offers you 5 graphic displays to choose from: G-Graphic, G-Meter, G-Counter and Stop Watch, along with a HorsePower function that measures and records the max horse-power of your car. You can specify what type of vehicle you are driving to calibrate the G-Analyzer by selecting from the following choices - Mid Size, Full Size, SUV, Van, Pickup Truck, Sporty or Compact. The GMA's information can be viewed as numerical data or enhanced graphics on the head unit's display.

Built-In 512MB Memory: The KDC-X991 features an internal 512MB memory which allows you to store audio tracks within the unit recorded from an inserted music CD or copied from a USB device via the unit's USB input a 1x speed. The KDC-X991 feature's 3 recordable time speeds. You can choose from Standard (8 hours of recording time), Long Play (12 hours of recording time) or Super Long Play (16 hours of recording time). Assuming that each track is recorded in a 64 kbps WMA format with a playback time of about 4 minutes, the unit's 512MB flash memory can hold up to approximately 16 hours of music or 240 audio tracks. You can also title your recorded tracks with a 5 character name using the supplied remote control.

Offset Dual Differential System: The KDC-X991's high quality sound is produced by the unit's Offset Dual Differential (ODD) Digital-to-Analog 24 Bit D/A converter system. Dual D/A converters are used, and the digital processing is isolated and controlled separately for the front channels to improve channel separation.

Supreme Setting: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When the Supreme Setting is Off, the unit plays the original sound stored in the audio file.

Digital Audio Platform (DAP): The KDC-X991 CD receiver features in innovative DAP platform that improves dynamic range and noise tolerance. It is further supported by Kenwood's original Supreme technology to restore the high-frequency elements that are often lost in a typical compressed audio file allowing for noise-free yet dynamic playback of digital sources.

Bass Management System (B.M.S.): This unit is equipped with an interface (pink/black wire in the wiring harness) which controls certain special features of B.M.S.-equipped Kenwood eXcelon amplifiers. This unit, when properly connected, can remotely activate and adjust the amount of bass boost in the amplifier. You can choose between +6dB, +12dB, or +18dB bass boost, or flat (no boost). In addition, you can lower the bass boost center frequency by 20%, switching between "Normal" and "Low".

Loudness: The Loudness feature compensates for low and high tones during low volume. You can turn this feature either on or off. Only the low tone is compensated for when the tuner is selected as a source.

Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0.

Clean Reception System Circuit (CRSC): This circuit controls multi-path distortion by reducing stereo separation. As stereo separation is reduced, multi-path has less effect on the radio signal, improving reception in areas with tall buildings and mountains. The CRSC circuit can be turned on or off.

Radio Data System (RDS): The unit's tuner features RDS (Radio Data System). RDS is a service used by some radio stations to transmit data outside of normal radio broadcast signals. When an RDS station is received, you can immediately find out what kind of data is being transmitted by looking at the program service name. RDS features an emergency transmission function that interrupts regular programming to broadcast an emergency announcement (such as a tornado or severe storm).
