Auto Level Control equalizes volume level
differences between tracks when playing music
from an iPod or other sources.
Multi-Channel Auto Level Control
Multi-channel Auto Level Control supports surround sound
playback, maintaining a consistent level and clear audio.
The function adjusts low and high frequency sounds, dialogs,
surround effects etc. that are difficult to hear in low volume,
to optimal levels — an ideal feature for listening at night
without disturbing others.
Hi-bit24 Audio Signal Processing
1122
This technology works to create undistorted sound,
bringing out the best in the 24-bit DAC. The 24-bit
DAC hardware alone does not reproduce better
sound. Maximum performance is gained by
applying the Hi-bit24 Audio Signal Processing to
expand signal resolution, creating more detailed,
smooth sound, closer to the original analogue
signal. Hi-bit24 also increases the sound pressure for a tactile
listening experience, and the more channels you have, the more
impressive it becomes. It is effective for multi-channel content
on CD/DVD, PC files less than 24-bit and works with any disc
player.
