[. . . ] 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. [. . . ] 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-860 functions such as volume saved under each page. The ADCOM universal remote controller is preset to operate all GTP-860 functions (MAIN and TUNER device mode) and most GCD-700/750 CD functions (CD device mode). Alkaline batteries are recommended for maximum operating life. 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. Each of these buttons cause two things to happen when used. If you then press the vid 5 device selector, the same play button would send a different command code that might, for example, start your mini-disc player. (Of course, this all depends on how you programmed the remote in the first place. This will be covered shortly. ) [30] Power Button In all modes, this is preprogrammed to turn the GTP-860 on and off. [31] Input Selector (tape, ext 5. 1) In main mode, these are similar to the source selectors described above but they switch only GTP-860 inputs. They DO NOT automatically change the functions of other remote buttons. ADCOM GTP-860 OWNER'S MANUAL | 17 [32] Mute 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. [36] Play Button In CD mode, it is preprogrammed for play with an ADCOM CD player. [37] Pause Button In CD mode, it is preprogrammed to pause an ADCOM CD player. [33] Dynamic Range Button In main mode, this button is preprogrammed to adjust dynamic range of Dolby Digital encoded sources. range button, which can be used only in combination with a Dolby Digital source, incrementally reduces the audio track's dynamic range in four steps (100%, 75%, 50% and 25%) to allow for comfortable listening under a variety of conditions. To adjust the dynamic range, each consecutive press of the d. range button will reduce the value in 25% increments, as shown in the alpha-numeric display section. 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.
