With the Double Bass function you can boost the bass 
output by feeding the bass sounds of the front left and 
right channels to the subwoofer. This function can be 
used only if the Speaker Config menu Subwoofer setting

When using progressive scanning, you may find that the 
picture and sound are out of sync. With the A/V Sync 
function you can delay the audio in 0.5 ms steps from 0 
to 74.0 ms to get the picture and audio back in sync. The 
default setting is 0 ms.

 

• If a delay time between 24.5 ms and 74 ms is set, and 

then the Upsampling function is turned on, the delay 
time will be fixed at 24.0 ms, however, the value 
shown on the display will not change.

• This function cannot be used with the multichannel 

input.

 

■

 

With Onkyo’s unique Enhanced Spatial Positioning 
Algorithm you can fine-tune the sound field by delaying 
the signals to all speakers in 0.5 ms steps from –4.0 ms 
to +6.0 ms (default is 0 ms). This 10 ms range equates to 
a physical speaker movement of 10 feet (3 m).
Before adjusting this setting, specify the distance 
between the listening position and each individual 
speaker (see page 43), and adjust the level of each 
speaker individually (see page 44).
By increasing the distance between the speakers (i.e., 
increasing the delay time), the sound field can be broad-
ened, and by reducing the distance (i.e., reducing the 
delay time), the sound field can be narrowed.

 

■

 

With this setting you can adjust the level of the LFE 
(Low Frequency Effects) channel for Dolby Digital 
sources in 1 dB steps from –10 dB to 0 dB (default is 
0 dB).
If you find that the low-frequency effects are too loud 
when playing Dolby Digital sources, lower this setting as 
necessary.

 

■

 

With this setting you can adjust the level of the LFE 
(Low Frequency Effects) channel for DTS sources in 
1 dB steps from –10 dB to 0 dB (default is 0 dB).
If you find that the low-frequency effects are too loud 
when playing DTS sources, lower this setting as neces-
sary.

The procedure for changing these settings is provided 
on page 68.
