3.1 On-Screen Display
The GTP-860
II is equipped with an
elaborate On-Screen Display (OSD)
facility. As the OSD is an essential tool
to set up the various parameters for
surround sound correctly it is recom-
mended that you connect your monitor
or television to the GTP-860
facility. As the OSD is an essential tool

OSD signal is only availble on the S-
Video and composite video outputs,
not on the component video output.

3.2 Speaker Config
In order to optimize the performance
of you system, the GTP-860 II can be
configured specifically for the speak-
ers in your system. Information about
each of your speakers allows the
GTP860 II to tailor the audio output
for best sound. The setup procedure
breaks your speaker system into five
groups: front, center, surrounds, sur-
round backs and subwoofer.
There are a few options for each group.

There are a few options for each group.
Front: small or large

Surrounds: small, large or none
Surr backs: yes or no
Subwoofer: yes or no

The large mode is used when the
speaker is full range and capable of
reproducing the entire audible fre-
quency spectrum from 20Hz to 20kHz.
The small mode is used when the
speaker is not capable of reproduc-
ing the deepest bass portion of the
audio frequency 20Hz to 80Hz. When
a speaker is set to small, the low fre-
quencies intended for that speaker
are redirected either to the front
speakers or the subwoofer. The front
speakers can only be set to small if
you are also using a subwoofer.

For best results, you should consider
using a center speaker. Ideally it
should be the same type as the left
using a center speaker. Ideally it
should be the same type as the left
and right speakers. Using a separate
center channel speaker will allow the
dialogue to cut through even the big-
gest sound effects and musical scores.
Having the sound spread across three
front speakers also stabilizes the ste-
reo image, making the usable listen-
ing area much bigger. If you do not
wish to use a center speaker select
“no” for the center speaker.

Installing surround speakers will
greatly enhance the surround experi-
ence as these speakers add consider-
ably to the overall sense of spacious-
ness in the playback system. It is best
to choose loudspeakers which are
similar in power handling and perfor-
mance capability to those of the front
channels. If you are using only one
pair of surround speakers, make sure
to connect them to the surround rear
outputs. If you choose to install the
surround back speakers, locate them
behind your listening position, and
connect them to the surround back
outputs. Surround back channels add
to the spaciousness and coherence
of the sound field, but the surround
rear channels must be present for the
desired effect. If you are using sur-
round back speakers select the surr
backs option to yes. Note that the
surround back speakers will track the
surround rear speakers with regard to
small/large settings.

Many film sound tracks rely heavily
on very low frequency sound effects
which are difficult for normal or
smaller hi-fi speakers to reproduce.
To faithfully reproduce these low
frequencies you can use a specially
designed low frequency loudspeaker
with its own built-in amplifier (“pow-
ered subwoofer”). Because it is dif-
ficult to hear which direction very
low frequencies come from, you only
normally need one subwoofer and
this can be placed virtually anywhere
in the room. Dolby Digital uses a
dedicated low frequency effects (LFE)
channel. If a subwoofer has been
selected, the LFE channel will be fed
to the subwoofer output.
