Advanced Setup—Continued

3-1. Tone Control

a. Bass
You can adjust the bass for the front left, right, and center
speakers and subwoofer in 2 dB steps from –12 to
+12 dB. The default setting is 0 dB. The bass cannot be
adjusted while the Direct, Pure Audio, or THX listening
mode is selected.
b. Treble
You can adjust the treble for the front left, right, and cen-
ter speakers in 2 dB steps from –12 to +12 dB. The
default setting is 0 dB. The treble cannot be adjusted
while the Direct, Pure Audio, or THX listening mode is
selected.

3-2. Surround Speakers

a. Surround Speakers
If you are using surround back speakers, you can choose
which surround speakers to use when playing 5.1 mate-
rial. This setting can be used with the following listening
modes: DTS, DTS96/24, Dolby Digital, Dolby Pro
Logic II, THX Cinema (PL II), Mono Movie, Orchestra,
Unplugged, Studio-Mix, and TV Logic.
Surround L/R: Use only the surround left and right
speakers.
Surround Back: Use only the surround back left and
right speakers.
Surr L/R+back: Use the surround left and right and
surround back left and right speakers.

3-3. Sound Effect

a. Re-EQ
This is the same as the Re-EQ function explained on
page 62. This function can be used with the following
listening modes: Mono, Stereo, All Ch St, Dolby Digital,
Dolby Digital EX, Dolby Pro Logic II Movie, DTS,
DTS-ES, and DTS Neo:6 Cinema.
b. Upsampling
With the Upsampling function you can double the sam-
pling rate for more detailed playback. Upsampling can
be used with the following listening modes: Stereo and
Dolby Pro Logic II.
On: Sampling rate doubled. (UPSAMPLING indi-
cator lights up.)
Off: Upsampling function off.
c. Double Bass
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
is set to Yes, and the Front L/R setting is set to Large (see
page 41).
On: Double Bass function on (default).
Off: Double Bass function off.
d. Late Night
This is the same as the Late Night function explained on
page 62. It can be used only when the listening mode is
Dolby Digital.
3-4. Delay
a. A/V Sync
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.
Note:
• 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.
b. Relative Delay
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.

3-5. LFE Level

a. Dolby Digital
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.
b. DTS
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.
