Current Marantz products carrying the 'Made for iPod' logo are compatible with the following iPod models: 5th Generation iPod or higher, iPod Classic, iPod Nano (1st, 2nd, 3rd and 4th generation), iPod video and iPod Touch. For 5th Generation iPod, iPod Nano or iPod Touch the audio transmission is digital. 'Made for iPhone' adds the iPhone compatibility to this list.
The use of compressed audio files like MP3, Windows Media™ Audio or AAC is getting more and more popular. The audio quality of these compressed files however is less than the original lossless files that are on a CD, especially lacking the higher frequencies and affecting the lower frequencies which make the audio image less wide and deep. The Marantz Digital Audio Expander 2, also called M-DAX2, recalculates the outputted frequency range. This enables you to get a more detailed and clearer sound.
Analogue video signals feed to the AV Receiver in Composite, S-Video or Component format will be up- or down-converted to the monitor video output of another format. This feature allows you to connect several sources to an AV Receiver and run only one cable to the TV set. Please check specification area for details on conversion direction.
