This section explains how to specify 
which speakers are connected and their 
sizes.
For speakers with a cone diameter larger 
than 16 cm, specify Large (full band). 
For those with a smaller diameter, specify 
Small (default crossover 150 Hz).
The crossover frequency can be changed in the

Crossover (Crossover Frequency)
This setting is advantageous for the speakers that you 
specified as “Small” in the “Sp Config (Speaker 
Configuration)” (

page 34). To get the best bass 

performance from your speaker system, you need to set 
the crossover frequency according to the size and 
frequency response of your speakers.

`

40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 
120Hz, 150Hz, 200Hz

Use the diameter of the smallest speaker in your system 
when choosing the crossover frequency.

*

Choose the setting suitable for the speaker.

• For a more accurate setting, look up the frequency response in 

the manuals supplied with your speakers and set accordingly.

• Choose a higher crossover frequency if you want more sound 

from your subwoofer.

■

`

`

Turn this setting on to boost bass output by feeding bass 
sounds from the front left, right, and center channels to the 
subwoofer. 

• This function can be set only if the “Subwoofer” setting is set to 

“Yes”, and the “Front” setting is set to “Large” (

page 34).

Here you can specify the distance from each speaker to the 
listening position so that the sound from each speaker 
arrives at the listener’s ears as the sound designer 
intended.

• These settings are disabled when:

– a pair of headphones is connected, or
– the  “Audio TV Out” setting is set to “On” (
