emphasized too much. In such a case, do not change the setting, or make the setting with the above option 1.

±
Noise can be heard
•
Using cable ties to bundle analog audio cables, power cords, speaker cables, etc. may degrade the audio performance. Do not bundle the cords.
• An audio cable may be picking up interference. Change the position of the cables.
±
The beginning of audio received by an HDMI IN cannot be heard
• Since it takes longer to identify the format of an HDMI signal than it does for other digital audio signals, audio output may not start immediately.
±
Sound suddenly reduces
• When using the unit for extended periods with the temperature inside the unit exceeding a certain temperature, the volume may be reduced
automatically to protect the circuits.
