For tuner functions (changing stations, etc.): 1. Press the tuner source selector button. It will flash red. 2. Press the tuning up (or tuning down) function button to change stations. The tuner source selector will flash red to confirm that the function button youve selected actually triggers a command. (Again, use the table to see which buttons are preprogrammed.) Press the CD source selector first to access preprogrammed commands for ADCOM CD players. NOTE: You can program new commands over the preprogrammed commands in tuner and CD if you wish. However, you cannot program any buttons, even those unprogrammed with GTP-760 command codes, while youre in main mode. This safety feature assures you that you will always be able to fully enjoy the GTP-760s capabilities. Programming Your Own Commands You can supplement preprogrammed commands with commands to operate other components. Before you begin to follow these steps, note the status LED located at the top left corner just above the remotes button panel: It will flash red, orange, or green to signal particular functions as you enter new commands into your ADCOM remote. Begin by deciding which source components commands you will be transferring to the ADCOM remote. Then press the appropriate source selector button. For example, if youre teaching your ADCOM remote commands for your DVD player, press the DVD source selector first. You can teach your remote new commands for any function button ( except backlight) after youve selected DVD, VCR, TUNER, V.AUX, CD, Dig.1 or Dig.2. 1. Place the source components remote head to head with the ADCOM remote. They should be in line with each other about 2 to 3 inches apart. 2. Press the ADCOM remotes appropriate source selector and select/play buttons simultaneously. Hold both buttons until the status LED turns orange and the source selector button glows red. Both indica tors should remain lit. 3. Decide which function button on the ADCOM remote you want to learn a new command. Press it. The orange status LED will begin to flash and the source selector LED will go out. 4. Find the corresponding button on the source components remote. Press and hold it until the status LED on the ADCOM remote flashes green once and remains green until the button on the source remote is released. Once the button on the source remote is released, the status LED will start flashing orange again. 5. Verify that the ADCOM remote has learned the new command by pressing and holding the same button on the source remote. The ADCOM remotes status LED should flash green twice and then go back to steady orange. This indicates successful programming. Release the button on the source remote. Repeat Steps 3 through 5 for any other commands you want to teach your ADCOM remote for that source component. Save the commands youve just programmed into the ADCOM remote by pressing and holding the appropriate source selector and select/play buttons simultaneously. Hold until the status LED and source selector LED flash twice and then go out. Repeat these steps for any other source commands you wish to program. 26

Second, the subwoofer trim appears in the CHANNEL BALANCE menu, but not during the operation of the noise sequencer. Because the subwoofer operates at a limited frequency range and because the sound level measurement is weighted, the noise sequencer method of channel trimming is often unreliable in setting the subwoofer level. Using such an approach can sometimes lead to pegging the subwoofer trim to its highest level on the GTP-760 to compensate. It is better to use the sequencer to set the level of the main, center and rear channels, then use the external volume control on the subwoofer itself to balance it to the system. Fine- tuning of the subwoofer level may still be done in the CHANNEL BALANCE menu while listening to a 5.1 channel soundtrack. 3.5 INPUT SETTINGS Congratulations, your GTP-760 is now fine-tuned and ready for enjoyment. The steps that have been completed in sections 3.2 through 3.4 need only be repeated if you change a component in your system or significantly alter the position of your speakers. In fact, you should consciously avoid using the CHANNEL DELAYS, SPEAKER SIZE or CHANNEL BALANCE menus again during normal operation as you will upset the system dependent parameters carefully entered during this procedure. While the three setup menus should be avoided, you may elect to use the INPUT SETTINGS menu of the OSD during normal operation. Highlight INPUT SETTINGS in the SETUP menu and press select/play on the remote. You will see a screen similar to the following: INPUT SETTINGS INPUT: TUNER VIDEO: COMPOSITE MODE: 2 CHANNEL DIALOG ENHANCE: OFF DYNAMIC RANGE: N/A LEVELS MENU UNDO CHANGES DONE This screen essentially broadcasts the same information displayed on the front panel of the GTP-760 but in a manner that can easily be viewed from the listening position. The available choices in each of the fields can be selected with the < and > buttons on the remote control. INPUT - identifies the selected input MODE - indicates the operating mode of the selected input (stereo, Pro Logic, DTS, Dolby Digital,etc.). DIALOG ENHANCE - indicates whether the dialog enhance function is active. The dialog enhance feature boosts midrange frequencies in the front and center speakers to emphasize dialog intelligibility. DYNAMIC RANGE - indicates the level of compression currently selected. (note: This applies only to digital inputs receiving a Dolby Digital signal). Choices are Full, 75%, 50% and 25%. The field shows N/A for modes when this feature is not available. The other two fields, VIDEO and LEVELS MENU, require further explanation. The VIDEO field displays the video mode of the selected source. As described in the Composite or S-Video box in section 1.2, the GTP-760 can save the video mode for each source. If you have elected to use either all composite or all S-Video connections, then there is no reason to change the settings in this field. (In fact it should be avoided as doing so may prove confusing. If you inadvertently highlight the VIDEO field and use the < or > remote arrow buttons, your screen display and background may disappear from the television. You have changed the video mode of the GTP-760 for the selected source. If this happens, without pressing any other remote buttons, simply press either of the < or > arrows again and the video screen will reappear). 33

Listening to Preset Stations 1) Select tuner and either FM or AM. 2) Press the appropriate preset button (or shift + the preset button for choices higher than preset 7). 4.3 Room 2 Operation Introduction The GTP-760s Room 2 circuitry gives you the ability to simultaneously enjoy two different audio/video sources in two different areas of your home. For instance, you can watch a DVD movie in the main family room while someone else enjoys a satellite broadcast or CD in the bedroom. Operating Room 2 From the Front Panel The room 2 button on the front panel of the GTP-760 performs three separate functions: Room 2 power ON; Room 2 status; and Room 2 power OFF. 1) To turn Room 2 power ON, press the room 2 button once . The LED in the center of the room 2 button will light to tell you that room 2 capability is on. 2) Once Room 2 is active, press the room 2 button again to display Room 2 status. The LEDs in the center of the six front panel analog source selectors will light to show you that you can route any of those sources to the GTP-760s Room 2 outputs. If one of the six source LEDs blinks, that source is already selected for room 2 distribution. (Note: You cannot direct a digital source - DVD, digital 1, or digital 2 - to the Room 2 outputs.) Choose the source you wish to direct to the room 2 outputs by pushing one of the lighted source selectors. The LEDs in the other source selectors will go out and the name of the source youve just chosen for room 2 distribution will briefly appear in the information display window. After five (5) seconds, the display will change to show the room 1 (main) source but the room 2 LED will still glow, indicating that a room 2 source is now active. You can verify the room 2 source selection any time room 2 capability is active (i.e., any time the room 2 LED is illuminated) by simply pressing the room 2 button again. Youll see all six analog source selector LEDs light. The active room 2 source LED will blink and the name of that source will show in the information display. Youll have ten (10) seconds to change the room 2 source by simply pressing any other illuminated source selector. 3) To power Room 2 OFF, press and hold the room 2 button until the red LED at the center of the button goes out (about 5 seconds time). Setting Room 2 Playback Volume You can change room 2 volume only by using the remote control. There is no way to adjust room 2 playback level from the GTP-760s front panel alone. 1) Press the remote controls main source selector once. This makes sure the remote is ready to generate GTP-760 command codes. 2) Press the room 2 button twice to access the room 2 status mode. 3) Use the remote controls volume up/down buttons within ten (10) seconds of pressing room 2. The front panel display will show room 2 level changes as you make them and will then revert to normal display mode ten (10) seconds after the GTP-760 receives the last volume adjust command. 37
