190 UNDERSTANDING YOUR INSTRUMENT PANEL Multisession disc formats are supported by the radio. Multisession discs may contain combinations of normal CD audio tracks and computer files (including MP3/ WMA files). Discs created with an option such as keep disc open after writing are most likely multisession discs. The use of multisession for CD audio or MP3/ WMA playback may result in longer disc loading times. If a disc contains multi-formats, such as CD audio and MP3/WMA tracks, the radio will only play the MP3/ WMA tracks on that disc. Supported MP3/WMA File Formats The radio will recognize only files with the MP3/WMA extension as MP3/WMA files. Non-MP3/WMA files named with the MP3/WMA extension may cause playback problems. The radio is designed to recognize the file as an invalid MP3/WMA and will not play the file. When using the MP3/WMA encoder to compress audio data to an MP3/WMA file, the bit rate and sampling frequencies in the following table are supported. In addition, variable bit rates (VBR) are also supported. The majority of MP3/WMA files use a 44.1 kHz sampling rate and a 192, 160, 128, 96 or VBR bit rates.
