With the SU9920, your audio system achieves a more defined sound with a solid bass foundation. It delivers natural treble by enriching overtones and more precise, punchy bass by phase compensation. The separate "Low Contour" and "Process" controls for each channel allow quick and easy adjustments and ultimate sound enhancement.

Fasten your seat belt and set off on new sound dimensions!

• More clarity, dimension and depth for dramatic sound enhancement
• Natural treble by enriching overtones and more precise, punchy bass by phase compensation
• Improvement of speech intelligibility and higher music presence
• Separate "Low Contour" and "Process" controls per channel for ultimate sound enhancement
• Precise, 5-stage LED level display for optimum performance
