Speaker Setup - Adcom GDV-850 Owner's Manual

Output Mode
Setting the output mode determines
what outputs are active and how the
signals will be dispersed to your pre-
amp. The options are 5.1Ch Surround,
2Ch Stereo (R L ), 2Ch Pro Logic (R
O O
and 2Ch Virtual.
Center
You have the option to turn the center
channel on and off. If you select "Off"
the audio for the center channel will be
processed and dispersed between the
left and right front channels.
Rear
You also have the option to turn the rear
channels on and off. If "off" is selected,
rear channel information will be sent to
the front speakers.
Subwoofer
If you have a subwoofer select "On,"
otherwise select "Off."
Cntr (Center) Delay
L ),
T T
Sometimes your center channel cannot
be placed at a distance that is equal
to that of your left and right speaker.
For every foot of difference apply one
milli-second delay. The options are 5ms
to 1ms and off, in 1ms steps.
Rear Delay
If your rear speakers are closer to your
listening spot than your fronts, adjust
this setting by adding delay to the
rear speakers. Add delay such that the
sound will arrive at the listening spot
from the front speakers and the rear
speakers simultaneously. Sound travels
about 1 foot per msec, so if your rear
speakers are three feet closer to the
listening spot than your fronts, add 3
msec. of delay.
Delays set in the DVD player will not be
duplicated by your preamp when the
signal goes out from your DVD player's
digital output.
Test Tone
Test tones are noise signals with a stan-
dardized level. An audible tone will play
in each of your speakers in a sequential
order, starting with left front. If any
channel has been deactivated in the
speaker setup, the test tone will pass
over this channel, without pausing the
test. If you do not hear a test tone
from a particular speaker, first ensure
the physical connection is correct and
secure. Then check to see if the channel
is active in the setup.
Rear/Cntr Size
The speaker size is important to set in
relation to your setup. The front left and
right speakers are always set to large.
If needed, this setting can usually be
