You can adjust each speaker’s (front left/right, 
front left/right high, center, surround left/right, 
surround back left/right) size.

Select the speaker on the screen for 
which you want to adjust the size, then 
press .

Select “Size”, then press 

.

• Large: If you connect large speakers that 

will effectively reproduce bass 
frequencies, select “Large”. Normally, 
select “Large”.

• Small: If the sound is distorted, or you 

feel a lack of surround effects when using 
multi channel surround sound, select 
“Small” to activate the bass redirection 
circuitry and output the bass frequencies 
of each channel from the subwoofer or 
other “Large” speakers.

This function does not work when “A. DIRECT” is 
being used.

• The “Large” and “Small” settings for each speaker 

determine whether the internal sound processor 
will cut the bass signal from that channel.

 

When the bass is cut from a channel, the bass 
redirection circuitry sends the corresponding bass 
frequencies to the subwoofer or other “Large” 
speakers.

 

However, since bass sound has a certain amount of 
directionality, it is best not to cut it, if possible. 
Therefore, even when using small speakers, you 
can set them to “Large” if you want to output the 
bass frequencies from that speaker. On the other 
hand, if you are using a large speaker, but prefer 
not to have bass frequencies output from that 
speaker, set it to “Small”.

 

If the overall sound level is lower than you prefer, 
set all speakers to “Large”. If there is not enough 
bass, you can use the equalizer to boost the bass 
levels.

• The surround back speakers will be set to the same 

setting as that of the surround speakers.

• When the front speakers are set to “Small”, the 

center, surround, and surround back/front high 
speakers are also automatically set to “Small”.

• If you do not use the subwoofer, the front speakers 

are automatically set to “Large”.

x Crossover Freq (Speaker 

Lets you set the bass crossover frequency of 
speakers that the speaker size has been set to 
“Small” in the Speaker Settings menu. 
Measured speaker crossover frequency is set 
for each speaker after the Auto Calibration.

Select the speaker on the screen for 
which you want to adjust the crossover 
frequency, then press 

.

Adjust the value, then press 

.

x Test Tone

Lets you select the test tone type on the “Test 
Tone” screen.

• To adjust the level of all speakers at the same time, 

press MASTER VOL +/–. You can also use 
MASTER VOLUME on the receiver.

• The adjusted value is shown on the TV screen 

during adjustment.

You can output test tone from the speakers in 
sequence.

Select “Test Tone”, then press 

 or

* “SB” appears when only one surround back 

speaker is connected.
