Setting the Media Xpander (MX) Media Xpander (MX) makes vocals or instruments sound distinct regardless of the music source. The SiriusXM, USB Flash drive and iPhone, will be able to reproduce the music clearly even in cars with a lot of road noise. Setting item: MX 1 Touch [On] of "All MX OFF/ON". 2 Touch any of [Off • To cancel MX mode, set [Off] in step 1. • MP3/WMA/AAC can have its own MX setting. • When the Defeat setting is [On], you cannot perform the set up. • The MX setting can be performed only when a source is currently selected. Setting Defeat If Defeat is [On], the MX and Equalizer setting are turned Off. This disables any settings made for these functions. Setting item: Defeat Setting contents: Off (Initial setting) / On About the Crossover Crossover (X-Over): This unit is equipped with an active crossover. The crossover limits the frequencies delivered to the outputs. Each channel is controlled independently. Thus, each speaker pair can be driven by the frequencies for which they have been optimally designed. The crossover adjusts the HPF (high pass filter) or LPF (low pass filter) of each band, and also the slope (how fast the filter rolls off the highs or lows). Adjustments should be made according to the reproduction characteristics of the speakers. Depending on the speakers, a passive network may not be necessary. If you are unsure about this point, please consult your authorized Alpine dealer.

Determine the recommended crossover frequency of the speakers. Adjusting to a frequency range outside that recommended may cause damage to the speakers. For the recommended crossover frequencies of Alpine speakers, refer to the respective Owner's Manual. We are not responsible for damage or malfunction of speakers caused by using the crossover outside the recommended value. 16-EN
