To resynchronize the front and surround chan-
nels, follow these steps:

1. Measure the distance from the listening/

viewing position to the front speakers in
meters.

2. Measure the distance from the listening/

viewing position to the surround speakers.

3. Subtract the distance to the surround speak-

ers from the distance to the front speakers
and multiply the result by 3.

a. When setting the delay time for the

Dolby Digital surround modes, the opti-
mal delay time is the result of that sub-
traction. For example, if the front speak-
ers are 3 m away and the surround
speakers are 1 m away, the optimal delay
time is figured as (3–1)x3=6. Thus, in this
example, the delay time for Dolby Digital
should be set at six 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
speakers are 3 m away and the surround
speakers are 1 m away, the optimal delay
time is figured as (3–1)x3+15=21. 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 pre-
ferred 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 posi-
tion.

If repositioning of the speakers is not possible,
adjust the center delay time, adding one mil-
lisecond of center-channel delay for every 30 cm
closer to the listening position the center speak-
er is than the front speakers. For example, if the

front-left and front-right speakers are each 3 m
from the listening position and the center-
channel speaker is 2.4 m away, the delay is fig-
ured as 300 cm–240 cm=60 cm, suggesting an
optimal center delay of 2 milliseconds.

To set the delay times, follow these steps:

1. Put the AVR 200RDS in the Dolby Pro Logic

mode by pressing the Dolby Pro Logic
Selector Ô on the front panel or by
pressing the Surround Mode Selectors

on the remote, until PRO LOGIC

appears in the Main Information Display
N and the PRO LOGIC indicator B
lights up.

2. Press the Delay button z ˜ on 

the remote or front panel. The words 
R DELAY TIME

(Rear Delay Time)

will appear in the Main Information 
Display N.

3. Press the Set button t 31 .

4. Adjust the delay time by pressing the 

‹

›

buttons r on the remote or the

Selector buttons 34on the front panel
until the delay time figure calculated using
the formula entered above for the Pro Logic
mode (item b.) appears in the display and
press the Set button t 31 to enter the
surround delay settings into the AVR’s 
memory. .

5. If only analog sources will be used, no

adjustment is needed for the center-channel
delay. However, if you will be using digital
sources with Dolby Digital mode and the cal-
culations outlined above indicate that the
center-channel delay requires an adjustment,
continue with the following steps.

6. Before setting the Dolby Digital delay times,

make certain that a digital input has been
selected, COAX G or OPTICAL F
will appear in the Information display N.

7. Select the Dolby Digital mode either by press-

ing the front panel Dolby Digital Selector
Ó or by pressing the Surround Mode
Selectors 

on the remote on the

remote until DOLBY DIG appears in
the Main Information Display N. Ignore
any “NO DATA” message that may
appear.

8. Press the Delay button z ˜ on the

remote or front panel. The words 
R DELAY TIME

appear in the 

Main Information Display N.

9. Press the Set button t 31 .

10. Press the 

‹

›

buttons r on the remote

or the Selector buttons 34on the front
panel until the desired rear delay time for
the Dolby Digital mode, calculated using the
formula for Dolby Digital above (item a.),
appears in the display.

11. Press the Set button t 31 to enter the

setting into the AVR200’s memory.

12. Press the 

‹

›

buttons r on the remote

once, so that C DELAY TIME
appears in the Main Information Display
N or in the on-screen display.

13. Press the Set button t 31 .

14. Press the 

‹

›

buttons r on the remote

until the desired delay time for the center
channel appears in the display.

15. Press the Set button t 31 to enter

the setting into the AVR 200RDS’s 
memory.

You have now completed the setup, adjustment
and calibration of the AVR 200RDS. You are
now ready to enjoy the finest in music and
home-theater listening.
