Configuring the DCR600 Receiver (Continued)
5. Continue to adjust the individual speakers
until they all have the same volume. Note
that adjustments should be made with the

Buttons yon the remote or the
Selector Buttons 5on the front panel
only, NOT the main volume controls. Then
press the Set Button Ôto memorize
the change. If you are using a sound pressure
(SPL) meter for precise level adjustment, set
the volume so that the meter reads 75dB,
C-Weighting Slow.
NOTE: The subwoofer output level is not
adjustable using the test tone. To change the
subwoofer level, press the Channel Select
Button Ûwhile playing a favorite selection,
and use the

the channel outputs to a desired level, and the
Set Button to memorize the change.
6. When you have adjusted the outputs so that
all channels have the same level, press the
Test Button hon the remote to complete
the adjustment.
NOTE: The output levels may be separately
trimmed for each digital and analog surround
mode. If you wish to have different trim levels
for a specific mode, select that mode and follow
the instructions in the steps shown earlier.
Setting Delay Times
Due to the different distances between the
front-channel speakers and the listening posi-
tion compared to the surround speakers and the
listening position, the amount of time it takes
for sound to reach your ears from the front or
surround speakers is different. You may com-
pensate for this difference through the use of
the delay settings to adjust the timing to match
the specific speaker placement and acoustic
conditions in your listening room or home
theater.
The factory setting is appropriate for most
rooms, but some installations create an uncom-
mon distance between the front and surround
speakers that may cause the arrival of front-
channel sounds to become disconnected from
surround-channel sounds.
To resynchronize the front and surround
channels, follow these steps:
1. Measure the distance from the listening/
viewing position to the front speakers.
2. Measure the distance from the listening/
viewing position to the surround speakers.
3. Subtract the distance to the surround speakers
from the distance to the front speakers.
a. When setting the delay time for the Dolby
Digital surround modes, the optimal delay
time is the result of that subtraction. For
example, if the front speakers are ten feet
away and the surround speakers are five
feet away, the optimal delay time is figured
as 10–5=5. Thus, in this example, the delay
time for Dolby Digital should be set at five
milliseconds.
b. When setting the delay time for the
Pro Logic mode, take the result of the sub-
traction and add 15 to obtain the optimal
delay time. For example, if the front speak-
ers are ten feet away and the surround
speakers are five feet away, the optimal
delay time is figured as 10–5+15=20. Thus,
in this example, the Pro Logic delay should
be set at twenty milliseconds.
NOTE: The Theater and Hall modes use a fixed,
nonadjustable delay time.
The Dolby Digital mode also includes a separate
setting for the center-channel delay mode, since
the discrete nature of these signals makes the
location of the center-channel speaker more
critical. To calculate the delay for the center
channel, measure the distance from the
preferred listening position in the center of
the room to both the center-channel speaker
and either the left or right speaker.
If the distances are equal, no further adjustment
is required and the center delay should be set to
zero. If the distance to the front speakers is
greater than the distance to the center speaker,
you may wish to reposition the speakers by
moving the front-left and front-right speakers
closer to the listening position or the center
speaker further away from the listening
position.
If repositioning of the speakers is not possible,
adjust the center delay time, adding one
millisecond of center-channel delay for every
foot closer to the listening position the center
speaker is than the front speakers. For example,
if the front-left and front-right speakers are each
10 feet from the listening position and the
center-channel speaker is 8 feet away, the delay
is figured as 10–8=2, suggesting an optimal
center delay of 2 milliseconds.
To set the delay times, follow these steps:
1. Put the DCR600 in the Dolby Pro Logic mode
by pressing the Surround Mode Selector 7
on the front panel or by pressing the
Surround Mode Selector ton the
remote, until PRO LOGIC appears in
the Main Information Display Wand the
PRO LOGIC Indicator Flights up.
2. Press the Delay Button Òon the
remote or front panel. The words S DELAY
TIME will appear in the Main Information
Display W.
3. Press the Set Button Ô.
4. Adjust the delay time by pressing the
⁄

¤
Buttons yon the remote or the
Selector Buttons 5on the front panel until
the delay time figure calculated using the
formula entered above appears in the display.
5. If only analog sources will be used, no adjust-
ment is needed for the center-channel delay.
In that case, press the Set Button Ôto
enter the surround delay settings into the
DCR600’s memory. However, if you will be
using digital sources and the calculations out-
lined above indicate that the center-channel
delay requires an adjustment, continue with
the following steps.
6. Before setting the center-channel delay time,
make certain that a digital source such as the
DVD600 has been selected. If a digital source
is playing, COAXIAL Eor OPTICAL Bwill
appear in the Main Information Display
Ú. If a digital source is already connected and
playing, press the Delay Button and
