User manual ADCOM GTP-600

[. . . ] It is particularly important that you connect your preamplifier to your amplifier and speakers while the amplifier and preamplifier is unplugged and your other equipment is turned off. This will protect your equipment from potential short circuits that may occur during installion. In addition, it is important that you allow for adequate ventilation around your preamplifier and other equipment, since excessive heat buildup can shorten the life of any electronic product, including the preamplifier. Once you have correctly connected your amplifier and speakers to your new preamplifier, you should be able to enjoy many trouble-free years of performance. [. . . ] Extreme caution must be used when changing the voltage of the unit, as an incorrect voltage selection will cause severe damage to the unit. See your dealer or contact ADCOM for more details regarding the operation of this switch.

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. The button description that follows distinguishes the function of each button dependent on the page the remote is in. The remote is shipped from the factory with ADCOM commands saved under the main, tuner, and CD pages, and with important GTP-600 functions such as volume saved under each page. The ADCOM universal remote controller is preset to operate all GTP-600 functions (MAIN and TUNER device mode) and most GCD-700/750 CD functions (CD device mode). Four AAA (R 03) batteries should be fitted in the battery compartment at the rear of the remote control. When replacing batteries, check that they have been put in correctly, as indicated on the base of the battery compartment. Eight Source Select Buttons The single most important aspect to master about the GRC-800 remote control is the function of the eight source select buttons at the top of the remote. These are the buttons labeled [56] and [29] in the figure on the opposite page. Second, THESE KEYS REMAP ALL OF THE OTHER BUTTONS ON THE REMOTE CONTROL. Although we usually prefer to reproduce a source's full dynamic range (the difference between very loud and very soft sounds), it may occasionally be desirable to reduce the dynamic range. For example, when playing a movie late at night, loud explosions might wake sleeping family members. Simply turning the volume control down would probably make a whisper in the next scene inaudible. range button solves this dilemma by progressively lowering the volume of loud peaks while increasing the level of softer sounds. [38] Stop Button In CD mode, it is preprogrammed to stop an ADCOM CD player. [39] Arrow Buttons The arrow buttons allow navigation throughout the GTP860 OSD (On Screen Display) menus (as well as the menus of other devices, once the commands are learned). Left arrow: In main mode, this is preprogrammed to step through the various choices you might wish to select while a menu item is highlighted. In CD mode, it is preprogrammed for audible reverse scan with an ADCOM CD player. Up arrow/Setup: In main mode, this is preprogrammed to enter the OSD menu system, as well as scroll up to the next choice on a menu screen. Right arrow: In main mode, this is preprogrammed to step through the various choices you might wish to select while a menu item is highlighted. In CD mode, it is preprogrammed for audible forward scan with an ADCOM CD player Down arrow: In main mode, this is preprogrammed to scroll down to the next choice on a menu screen. [34] Volume Up/Down Buttons In all modes, these buttons change the master volume setting of the GTP-600. The Volume control does not affect recordings made using the Tape and Video, or Tape, Video 3 and Video 4 outputs but will affect the signal going to the Preamp output. [40] Select Button In main mode, this is preprogrammed to enter a selection chosen via the menu system. [35] Mode Button In main mode, this is preprogrammed to cycle through the surround modes of the GTP-600. Pressing repeatedly will cycle through Pro Logic, Hall, and Stereo, when available. [. . . ] Usually putting another component between them is sufficient to minimize the hum. If this does not reduce the hum, turn the system off and disconnect all Inputs from the amplifier. If the hum still persists, then your Dealer or Service Center must examine the amplifier. Connect one RCA cable at a time to see if one specific cable is responsible. [. . . ]
