INTRODUCTION Congratulations on your decision to purchase the ADCOM GTP-860 tuner-preamplifier. The GTP-860 provides Dolby Digital and DTS decoding with 7.1 output channels, as well as a 5.1 analog bypass and the RDS radio data system. These features and ADCOM’s legendary quality provide the heart of your cutting-edge home theater. You have made a wise choice that will reward you for years to come with exceptionally accurate and musical sound reproduction.

1.1 Interface Overview The GTP-860’s front panel is designed for ease of operation. All controls are logically grouped for easy, intuitive operation. Familiarize yourself with the preceding diagram and read the short explanations of each feature below. When you finish, you will be well on your way to enjoying the GTP-860’s convenience and sound quality. [1] Power Button Depress the Power button to switch the preamplifier to its ‘Stand-By’ mode. The amber LED in the power button will light up.
However, very weak radio station signals may be suppressed by the muting circuit. If such a very weak station is in stereo it will have a high level of background hiss. Switching to Mono Mode and disengaging the muting circuit by depressing the FM Mute/High Blend button will allow the station to be heard and will cancel most or all of this background noise. In normal operation the mute circuit is engaged, and the display indicates “FM MUTE.
search mode. When tuned accurately to a station, “TUNED” will light up in the display. [6] Tune/Preset Button The Tune/Preset button toggles between the Preset and Tune mode. When Preset mode is selected, “PRESET” lights up in the display area. Refer to the Tuner Up/Down button [5] description for more information. [7] Display Window The display area shows all vital information when the unit is operational.

NOTE: No ext 5.1 audio signal is available from the headphones socket, or the Tape, Video 3 or Video 4 outputs.

1.2 Inputs & Outputs System Connectiotns Like the front panel, the GTP-860’s rear panel is carefully arranged to make hookup, configuration, and use as simple as possible. However, the GTP-860’s capabilities take some study to use most effectively. We strongly suggest that you read this section of the manual before beginning to hook up your system.
The video signal available on the S-Video and Video Composite outputs is dependent on the selected video input (Video 1, Video 2, Video 3, Video 4, Video 5). However, when one of the audio-only sources is selected (FM, AM, CD, Tape Monitor or ext 5.1) the last selected video signal from one of the video inputs will be present on these outputs. This way you can watch a DVD player or video while using the 5.1 analog audio inputs from a DVD player, as you might do when listening to a DVD-A or SACD disc.

REMOTE CONTROL 2.1 Overview of the GRC-800 The GRC-800 remote control is a learning remote control that is capable of saving commands for all remote controls in your home theater system. In this way, you may eliminate the confusion of using multiple remotes. Although such power comes with some added complexity, the complexity is minimal and with some repetition will become second nature.
[32] Mute Button [36] Play Button In all modes, this button is preprogrammed to mute outputs of device. Mute does not affect recordings made using the Tape outputs but will affect the signal going to the Preamp Outputs. When the unit is in mute mode, any adjustment of the Volume Control on the front panel [8] will release the muting, i.e. the original volume level will be resumed. In CD mode, it is preprogrammed for play with an ADCOM CD player.
[42] Test Button [49] RDS Button 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 cycles automatically with 3second intervals from Front Left, Center, Front Right, Rear Right, Back Right, Back Left, Rear Left, to Subwoofer in continuous cycles.

2.3 Programming Your ADCOM GRC-800 Remote Controller The ADCOM universal remote controller operates eight different audio/video components. As you’ve already seen, it’s preprogrammed to control ADCOM’s GTP-860 Preamp/ Tuner and the GCD-700/750 CD players. In addition, it has seven “component memory banks” available so you can program the remote to learn commands for your DVD player, satellite box, laser disc player, VCR, etc. This lets you use one remote controller for your entire system.
Repeat Steps 3 through 5 for any other commands you want to teach your ADCOM remote for that source component. Deleting All The Programmed Commands for Every Source Component Save the commands you’ve just programmed into the ADCOM remote by pressing and holding the appropriate source selector and select 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.
For example, if the m1 button is programmed in Group 1 mode to turn on the TV, turn on the audio receiver, turn on the VCR, and then turn on the satellite receiver, it will perform the same series of commands whenever the m1 button is pressed IF main, vid 1, vid 2, or vid 3 sources are selected at the time you select that macro. If you’ve programmed a Group 2 macro, it will send out an identical command sequence whenever vid 4, vid 5, tuner, or CD inputs are selected.

OPERATION & SETUP After connecting your home theater, you may elect to configure the GTP-860 to the specific speaker arrangement and dimensions of your system. The procedures described in this section demonstrate how to use the GTP860’s on screen display to enter this information. Once complete, the GTP-860 stores this information so that these tasks need only be repeated if speakers are changed or substantially repositioned. 3.
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. Highlight SAVE & EXIT and press Select to save the settings and return to the SETUP menu. Press the Test button again to leave or cancel the Test mode; any changes will be memorized automatically. 3.
Scroll through the preset delay time options and select the desired time. When both delays have been entered, choose “SAVE & EXIT” to save the settings and return to the Main Menu. In Dolby Digital surround mode, the rear channel delay time can be set from 0ms to 15ms with 1ms increments. The center channel can also be delayed up to 5ms, in 1ms steps. In Dolby Pro Logic surround mode, the rear channel delay time can be set from 15ms to 30ms and 1ms per step.
ately limited in dynamic range and frequency bandwidth for the surround channel and thus only requires speakers of far lesser capabilities compared to the front channels. Dolby Digital, however, is a full range system with two independent surround channels and with dynamics equal to that of the front channels. For this reason it is advisable to choose loudspeakers which are similar in power handling and performance capability to those of the front channels.
