Adcom GTP-600 - Manual (Page 13)

16) AC LINE CORD: This should be plugged into an unswitched outlet providing the appropriate voltage at either 50
or 60 Hz. If the unit is without AC power for an extended period of time, usually longer than 48 hours, station
memory and remote turn-on features may be affected.
BASIC OPERATION
17) VOLUME DOWN — POWER ON!: Avoid unintentional initial high sound levels by turning the volume control
down (fully counterclockwise) before powering the system.
18) SOURCE SELECTION and RECORDING : The GTP-600 provides extensive recording and “cross dubbing”
capability. Any selected source is available at all audio and video recording outputs. The only exception to this
rule occurs when you are transferring from one recording device to another; The GTP-600 automatically blocks,
for example, the output from
Tape 1 from appearing at the inputs of the same device. This prevents any inadvertent
and possibly destructive feedback loops from developing.
19) THE TUNER: The Tuner section is responsible for processing and amplifying extremely weak signals “pulled in”
by the appropriate antenna. ADCOM’s refined quartz synthesis technology makes this a highly accurate exercise.
However, Using the tuner is a simple process.
A) The Display window O provides an instant status check of the following important items:
1) AM & FM signal strength; Up to five red LEDs on the left hand side of the display will light depending on
signal strength. This display can help you find the best location for your antenna — the more LEDs
showing, the stronger the signal.
2) FM/AM band/frequency indicator: This is displayed at the center of the window.
3) FM “Seek" mode indicator; Appears immediately above the “MHz” indicator. Note that Seek does not
function in AM. (See Section B2 below.)
4) Preset indicator; Located on the far right hand side of the display, this lights when one of the pre­
programmed stations is chosen,
B) After selecting FM or AM (©or ©), tune to the desired station by one of the following methods:
1) Press one of the Tuning up/down arrows O until the Display © shows the proper station frequency.
2) Enter “Seek” mode (FM only) by pressing the Seek/manual button ©. “Seek" appears in the display.
Then press either of the Tuning up/down arrows ©. The GTP-600 will automatically advance to the next
active broadcast frequency. Note: “Seek” is not operative in AM mode.
3) Press any of the Tuner Preset buttons © to recall preprogrammed station frequencies. Of course, this
works only after you’ve programmed your favorite stations. Here's how;
a) Tune to ll ie desired broadcast frequency by using either of the methods outlined in B1 or B2 above.
b) Decide what preset # you want to assign to that frequency.
c) Hold down the corresponding button until the word “preset" and that number appears on the right
hand side of the display.
Note that preset positions 1 through 7 are accessed directly — simply push the button with the
corresponding number.
To access presets 8 through 14, press the Shift button © and then a preset button. For example, if
you want preset number 11, press Shift and then press Preset 4 (7+4=11). If you want preset
number 8, press Shift and Preset 1 in that order (7+1 =8).
Note that the +10 button on the remote is the equivalent of the shift button on the front panel.
All preset numbers are “random” in that you can assign any preset number to any FM or AM signal.
In other words, preset 1 can be AM, presets 2-4 can be FM, preset 5 can be AM, etc.
C) The High blend button © can reduce the background noise sometimes encountered on weaker stereo FM
signals. The “In” position also turns off the FM mute circuit and may make it possible to receive very weak
signals that would otherwise be ignored by the tuner’s circuitry.
