The Avalon is the first Toyota to combine JBL Synthesis 7.1 Surround Sound with GreenEdge technologies. Its high-voltage Class-H amplifier is engineered to produce high Sound Pressure Levels (SPL) with reduced current draw, while delivering 12 channels of digitally programmed sound to the system's 15 dedicated speakers.
JBL Synthesis 7.1 Surround Sound uses proprietary software to convert two-channel stereo signals into multichannel formats, providing a very engaging surround-sound experience to all vehicle occupants. Whether the original source is broadcast radio, SIRIUS Satellite Radio, CD or even MP3 files, you'll hear full and engaging surround sound throughout the passenger compartment.
