About Supreme
Technology to extrapolate and supplement with proprietary
algorithm, the high-frequency range that is cut off when
encoding at low bit rate (less than 128Kbps, Sampling
frequency is 44.1kHz).
Supplementing is optimized by compression format (MP3
or WMA) and processed according to bit rate.
The effect is negligible with music that is encoded at high
bit rate, variable bit rate or has minimal high frequency
range.
• About Dual Zone System
