GTP-870HD Owner’s Manual
Delay Configuration
How far is each speaker from your primary listening
area? The GTP-870HD uses this information to cal-
culate differences in distance and adds milliseconds
of delay if necessary to ensure that all audio signals
reach your ears simultaneously from all speakers.
The following is an overview of the Delay Configura-
tion menu.
To access the Delay Configuration menu:
1 Press the Main button on the remote control.
2 Press the Setup button.
3 Use the / buttons to select DELAY CONFIG,
then press the Select button.
4 Use the / buttons to choose from the follow-
ing menu items:
FRONT
Sets the distance from your front speakers to your
primary listening area in feet or meters (see Delay
Unit below). Measure this distance, then use the

/ buttons to select:
• 0-20 feet (0-6.1 meters)
• The front distance is the benchmark setting for
all other speakers, so measure this distance care-
fully.
CENTER
Sets the distance from your center speaker to your
primary listening area in feet or meters (see Delay
Unit below). Measure this distance, then use the

/ buttons to select:
• 0-20 feet (0-6.1 meters)
• The center speaker is often closer to the primary
listening area than the front speakers. If so, the
GTP-870HD calculates the difference in distance
and adds delay accordingly.
SURROUND
Sets the distance from your surround speakers to
your primary listening area in feet or meters (see
Delay Unit below). Measure this distance, then use
the / buttons to select:
• 0-20 feet (0-6.1 meters)
• The surround speakers are often closer to the
primary listening area than the front speakers.
If so, the GTP-870HD calculates the difference in
distance and adds delay accordingly.
SURR BACK
Sets the distance from your surround speakers to
your primary listening area in feet or meters (see
Delay Unit below). Measure this distance, then use
the / buttons to select:
• 0-20 feet (0-6.1 meters)
• The surround back speakers are often closer to
the primary listening area than the front speak-
ers. If so, the GTP-870HD calculates the differ-
ence in distance and adds delay accordingly.
SUBWOOFER
Sets the distance from your subwoofer to your pri-
mary listening area in feet or meters (see Delay Unit
below). Measure this distance, then use the /
buttons to select:
• 0-20 feet (0-6.1 meters)
• The subwoofer is often closer to the primary lis-
tening area than the front speakers. If so, the
GTP-870HD calculates the difference in distance
and adds delay accordingly.
DELAY UNIT
Sets the unit of measurement for channel delays.
Use the / buttons to select:
• Feet or Meters.
