3.0 Operation & Setup

After connecting your home theater,

you may elect to configure the GTP-

860II to the specific speaker arrange-

ment and dimensions of your system.

The procedures described in this sec-

tion demonstrate how to use the GTP-

860II’s on-screen display to enter

this information. Once complete,

the GTP-860II stores this informa-

tion so that these tasks need only be

repeated if speakers are changed or

substantially repositioned. In addi-

tion to speaker setup, many other

operations can be configured using

the on-screen display system.

3.1 On-Screen Display

The GTP-860II 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-860II. The

OSD signal is only availble on the S-

Video and composite video outputs,

not on the component video output.

The OSD is engaged by pressing main

and then the setup button on the

remote control. The SETUP Menu will

appear as below:

Use the cursor buttons [36] on the

remote control to navigate between

the available options. The up and

down arrow buttons are used to navi-

gate and select an option. The left

or right arrow buttons are used to

change settings, and select [37] is

used to choose the desired option.

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.

Front: small or large

Center: small, large or none

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.

If you are not using one of the speakers

in a group select “none” and the infor-

mation for that channel will be redi-

rected to the speakers you are using.

For best results, you should consider

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.
