GTP-830 DIGITAL PROCESSING TUNER/PREAMPLIFIER

What this section is all about . . .

After connecting your home theater, you may elect to configure the GTP-830 to the specific speaker arrangement and dimensions of your system. The procedures described in this section demonstrate how to use the GTP-830’s on screen display to enter this information. Once complete, the GTP-830 stores this information so that these tasks need only be repeated if speakers are changed or substantially repositioned.

3.1 On Screen Display (OSD)

The GTP-830 is equipped with an elaborate On Screen Display facility (OSD). As the OSD is an essential tool to set up the various parameters for Surround sound correctly it is recommended that you connect your monitor or television to the GTP-830.

Depending on your source and/or the television sys- tem used you must first select the correct video sys- tem. If the OSD rolls over the screen you must select another system: PAL or NTSC.

While pressing the Memory button [04] on the front panel, press the Video 1 input selector button [11] repeatedly until the desired system is shown in the display area. The OSD can be engaged by pressing one of the four cursor buttons on the remote control. The SETUP Menu will appear as below:

SETUP

Select is used to choose the desired option. Otherwise, highlight EXIT and press Select to leave.

The OSD menus are at maximum two “layers” deep; this means that from the main menu (layer 1) you can select a sub menu (layer 2).

3.2 Channel Balance

The output levels of each of the speakers connected to the GTP-830 may need to be adjusted so that there is an even balance of sound from all the speakers in the system. If, for instance, the relative volume level to the Left and Right speakers and the Center speaker is set too low, most of dialogue may be difficult to follow. If, on the other hand it is set too loud, the overall balance will sound unnatural.

To adjust the channel balance the GTP-830 is equipped with a Test button [37] to help assess the loudness levels of each speaker. Before adjusting the channel balance level make sure the master volume is turned down to a normal listening level.

Pressing the Test button engages the Test signal generator to allow for adjustment of all speaker levels, so that each channel can be adjusted for equal loudness at your listening position. The test signal scrolls automatically with 3 second intervals from Left, Center, Right, Rear Right,Back Right, Back Left, Rear Left, to Subwoofer in continuous cycles. If an adjustment in setting is made for one of the channels, scrolling will stop until 3 seconds after the adjustment was made. Both the display panel and OSD show which speaker is being fed with the test signal. Use the Left and Right arrow buttons to increase or decrease the level for the current speaker.

The Up and Down arrow buttons are used to navigate and select an option (indicated by highlighting the available option). The Left or Right arrow buttons are used to change a setting from the highlighted section, and

The Channel Balance for each speaker can be adjusted in 1dB increments. (The back channels are adjusted in 2 dB increments.) Continue to calibrate the level for each speaker until equal loudness is achieved at your listening position. A more accurate adjustment can be made using a sound level meter, if available. Set the meter to “Slow” and “C-weight- ed” modes and re-check the settings with the meter placed in several different positions in the general listening area.

Select the channel for which you wish to adjust and set the level so that it matches the other channels. For best results, start with the Left channel set at
