for a telephone call. Adjust the voice of caller.

environment without changing the built-in

• 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, 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.
• SUPREME PLUS
Improved version of SUPREME. It compensates
the clarity and transparency of the voice in the
compressed audio files and CD-DA music to
produce highly realistic vocal sound.
• ZONE2 (Dual Zone)
Set the destination (front speaker "FRONT" or rear
speaker "REAR") of the sub source (AUX IN) when
