results, start with the Left channel set at 0dB and to match the other channels to it. Normally, if the Right speaker is located at the same distance from the listening position to the Left speaker it should be set at the same level as the Left speaker.

Press the Test button again to leave or cancel the Test mode; any changes will be memorized automatically.

NOTE: There is no output in the Subwoofer during noise sequencer operation; therefore it is difficult to adjust the level in test mode. The Subwoofer level can be adjusted in the OSD setup menu with musical input.

After setting the balance with the Test function, you may wish to make further adjustments by ear, depending on the material you are listening to. There are two ways to access the Channel Balance screen, which allows you to adjust levels while monitoring a source.

Highlight CHANNEL BALANCE in the SETUP menu and press Select on the remote. You will see a screen similar to the following:

The GTP-860 allows the volume of each speaker to be individually trimmed so that none of the speakers domi- nates in playback and detracts from the surround illusion.

Highlight the speaker you wish to adjust, using the Up and Down arrow buttons. Use the Left arrow button to lower the output level, and the Right arrow button to raise the output level. Each speaker can be adjusted within a -10 to +10dB range, in steps of 1dB. The back channels can be adjusted within a -60 to +10 dB range, in steps of 2dB.

Highlight SAVE & EXIT and press Select to save the set- tings and return to the SETUP menu.

The Channel Balance menu can also be accessed directly with the bal button [39] on the remote control.

3.3 Channel Delays

For the best surround sound performance it is important that sound from all speakers reach the listener’s ears at the same time. Because the surround/rear speakers are usually closer to the listener than the front speak- ers, there is a tendency for the ear to localize sounds to the rear, because the ear takes most notice of the sounds that arrive at the head first. Similarly, the center speaker is often closer to the listener than the front left and right speakers. To compensate for this, the GTP-860 can slightly delay the audio sent to the center and rear (closer) speakers. In this way, when playing Dolby Digital or Dolby Pro Logic soundtracks, the sound from all speak- ers arrives uniformly at the listening position as intended by the film’s producer.

Each millisecond corresponds approximately with 1 foot or 30.5 centimeters.

To set the center channel delay time:

Call up the SETUP menu of the On Screen Display. Select the Channel Delays menu:

CHANNEL DELAYS

CENTER : 1ms

SURROUNDS : 5ms

DO NOT SAVE AND EXIT

SAVE AND EXIT

Choose CENTER and select the desired delay time (1, 2, 3, 4 or 5ms).

To set the surround channel delay time:

Use the Up or Down arrow buttons [39] to highlight the Surrrounds.
