If the setting of the front speakers is "Full Band", the low range elements will be output from the front speakers instead of from the subwoofer during

2. Change "Double Bass" to "On".
The low range elements of the front speakers will be output from both the front speakers and the subwoofer. Due to this, the bass sound may be
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.
±
Sound suddenly changes
• When "My Input Volume" is set, the volume is set for each input selector. Check "Source" - "My Input Volume" on the Setup menu.
