• We recommend that you first adjust the speaker balance with 

test tones (page 15).

• You can check the volume level in detail with the Status 

indicator (page 18).

• The adjustable range for the volume level of each speaker 

channel is as follows.
– Center: –4 (Min) to + 4 dB (Max)
– Surround: –4 (Min) to +4 dB (Max)
– Subwoofer: –8 (Min) to +8 dB (Max)

• You cannot adjust the left and right surround speakers 

individually with this procedure. To adjust them individually, 
carry out the “Adjusting the speaker balance with test tones” 
procedure (page 15). 

This unit employs the Yamaha Air Surround system that 
enables the surround sound field using six speaker units 
built in two satellite speakers. To create better acoustic 
field, please adjust the orientation of the virtual surround 
speakers suited for your listening environment. You can 
select from five presets for each satellite speaker (L and 
R).

To create better acoustic field, you may need to change the 
arrangement of the satellite speakers or furniture. For example, 
the Air Surround system does not work well (or does not work at 
all) in the following situations.
– The satellite speakers are placed inside the rack.
– The satellite speakers are not placed perpendicular to the side 

walls.

– There is an obstacle at the front (or diagonally in front) of 

satellite speakers.

– A piece of furniture is placed at the reflection points (A, B).
– There are no reflection faces (walls or windows).

• You cannot adjust the orientation of the virtual surround 

speakers while the DVS function is activated. To adjust it, press 
qVS to disable the DVS function.

• When headphones are connected to the 

 SILENT CINEMA 

jack on the unit, the adjustment is not available.

Press TEST.
Each speaker outputs the test tone for about 2.5 
seconds in order.

Press L once to check the current orientation 
of the virtual left surround speaker, or press 
R once to check the current orientation of the 
virtual right surround speaker.
The Status indicator blinks to show the current 
orientation for about 2.5 seconds. By the factory 
setting, “40°” is selected for each speaker.
