The AM/FM tuner and the TV tuner have the ability to scan for the strongest stations in the area and memorize them into the current band. There are three bands of six FM stations, one band of six AM stations, and two bands of 12 TV stations. Support is also provided for XM Satellite Radio if you purchase the optional tuner. XM stations can be displayed and selected either by category or station number, and you can store up to six favorites.
Audio adjustments begin with a parametric equalizer with storage for nine curves (four factory presets, four custom, one flat). Each custom curve has three bands at any of 26 ISO 1/3-octave center frequencies and 12dB of cut/boost in 2dB increments. A position selector sets the delay on each speaker for optimum listening in the driver's seat, the passenger seat, or both.
Each speaker output has level and time alignment adjustments, and LPF/HPF (crossover) selections at six different cutoff frequencies. A test tone (pink noise) rotates through all outputs for level adjustments, and holds at the speaker you are adjusting until you are finished and the rotation continues. The time alignment lets you adjust the delay at each output in 1-inch (25.4mm, 73.6Sec) increments up to 200 inches (16.7ft, 14.7Sec). Using the microphone provided, you can run an automatic time alignment, equalizer, and speaker level adjustment for any given location in the vehicle. You can switch between the memorized settings created by this automated procedure and your own custom settings at any time. Equalizer and time alignment functions are disabled when playing a disc with a sampling rate above 96kHz, and playback is only provided through the front speakers. These sacrifices are made to hand over more DSP power to the playback of the audio. The subwoofer output has a polarity switch to invert the signal to subwoofer. Source level adjustment is provided for AM, CD, DVD, AUX, and external units, with 8dB gain. The Direct setting shuts off all audio adjustments except volume level so you can easily compare your adjustments to a flat, no delay condition. Additional processing includes Dolby Pro Logic II, which creates five full-bandwidth channels from two-channel sources, with settings for movies, music, and "matrix" (for weak FM reception). When in Music mode, adjustments are provided for Panorama (on/off), Dimension (front to rear 3), and Center Width (0 to 7). These settings let you control the imaging. Automatic muting/attenuation of the audio - either when your cell phone rings or voice guidance is apparent in the output - from the optional navigation system can be adjusted for Mix (equal level of both sources), or attenuation of the current source by -10dB, -20dB or full mute.
This is a fantastic display of engineering excellence, with so many expansion capabilities that you are not likely to think of an application that is not supported. The audio and video quality is excellent, and learning to use the deck is a piece of cake. If you are looking for the centerpiece for a fully enabled mobile multimedia system, this is it.
