3.6 Delay Configuration
Setting the speaker delay is crucial to the proper perfor-
mance of any surround decoder component like the GTP-
880. Your home theater system will not perform properly if
this process is not completed.
To accomplish this process you will need a tape measure or
other means of determining the distance of each speaker
from the primary listening position.
To set the speaker distance delays for your speakers:
1. Press the menu button to enter the main menu. The
main menu appears the OSD. The cursor on the OSD should
be pointing to the input configuration menu.
2. Press the button until the delay configuration menu is
selected.
3. Press select to enter the delay configuration menu.
The delay configuration menu appears on the front panel
display and the OSD. The selected menu item should be
front L/R delay.
Before setting the speaker distances, you need to choose
what unit of distance you will be using.
4. Press the button repeatedly until the distance unit
menu is selected.
5. Use the and buttons to select between feet and
meters.
6. Press the button repeatedly until you return to the
front distance menu. To set the distance for each group
speakers in your system, you will need to measure, the
distances from your chosen listening/viewing position to
the various loudspeakers in your system.
Set the distance for the front L/R speakers to the nearest
foot/meter. Rounding up is OK. Distances can be set in the
following increments:
Feet 0 to 20 feet in 1 foot increments.
Meters 0 to 6 meters in 0.3 meter increments.
