1.1 Front Panel Controls The GTP-830’ s front panel is a model of simplicity . 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-830’ s convenience and sound q[...]

[ 03 ] FM Mute/High Blend button: This button combines two functions; it switches the tuner from Stereo to Mono and disengages the muting circuitry at the same time. The muting cir- cuit will mute the tuner in between radio stations when searching or tuning to avoid tuning noise. However , very weak radio station signals may be suppressed by the mu[...]

By briefly tapping the Down or Up buttons you can engage manual tuning respectively down or up the frequency band for precise tuning to a specific fre- quency . With each[...]

[ 11 ] Input Selector buttons: These buttons select the active video and audio input for the GTP-830 and the audio signal sent to the Preamp Outputs, T ape, Aux Outputs, Video 3 & 4 and TV monitor outputs. Video inputs 1, 2 and 3 also select the Digital Inputs 1, 2 and 3, respectively . Video 1: V ideo 1 selects the signal from a TV/Satellite/C[...]

1.3 The Remote Control The GTP-830 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[...]

[ 27 ] Mute button: In all modes , this button is preprogrammed to mute outputs of device. Mute does not affect recordings made using the T ape outputs but will affect the signal going to the Preamp Outputs. When the unit is in mute mode, any adjustment of the V olume Control on the front panel [ 08 ] will release the mut- ing, i.e. the original vo[...]

[ 37 ] T est button: Pressing the test button engages the test signal generator to allow for adjustment of all speaker lev- els, so that each channel can be adjusted for equal loudness at your listening position. The test signal cycles automatically with 3-second intervals from Front Left, Center , Front Right, Rear Right, Back Right, Back Left, Re[...]

NOTES: Direct sunlight or very bright ambient lighting may affect the operating range and angle for the remote control handset. The infrared remote control command receiver , locat- ed to the right of the Power button, receives com- mands from the remote control. There must be a clear line-of-sight path from the remote control to this win- dow; if [...]

Programming your ADCOM GTP-830 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-830 Preamp/T uner and the GCD-700/750 CD players. In addition, it has seven “component memory banks” available so you can program the re[...]

The ADCOM remote’ s 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 wa[...]

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.

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 T est button again to leave or cancel the T est mode; any changes will be memorized automatically . NOTE: There is no output in [...]

Scroll through the preset delay time options and select the desired time. When both delays have been entered, choose “SA VE & 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, i[...]

Installing surround speakers will greatly enhance the surround experience as these add considerably to the overall “ambiance.” Dolby Pro Logic encoded material is deliberately limited in dynamic range and frequency bandwidth for the surround channel and thus only requires speakers of far lesser capa- bilities compared to the front channels.
