EXPLANATION OF AUTOMATIC SOUND VALUE CORRECTION CONTROL
1. Outline
The recent trend is toward rise of SOUND level in the world, for example rock, dancing music, etc. In case of continuous high
level playback and VOL (Volume) are controlled (lowered) automatically after a lapse so as to get the easy-to-listen sound level.
The ALC (Automatic Level Control) of the HT-DD5000 begins to operate immediately after the power is turned on.
2. Explanation of operation

2 The ALC (Automatic Level Control) will begin operation immediately after the power switch is turned on.
If the sound exceeds level X , the ALC will instantaneously cut the volume back to level X , and it will also respond to
3 monophonic signals.
Since this control only effects the VOL level, it does not otherwise change the quality of the sound.
