Adcom GTP-740 - Manual (Page 34)

Highlight INPUT if necessary (the Up/Down arrow buttons) and press either the < (left arrow) or > (right
arrow) buttons to scroll to the input you want to modify. (Wait about 2-3 seconds after pressing < or >.
This gives the GTP-740’s microprocessor array time to reset and check all system parameters.)
When you’ve selected the input, the screen displays the currentiy selected defaults associated with that
input. For example, you might see;
INPUT SETTINGS
INPUT: TUNER
VIDEO; COMPOSITE
MODE: 2 CHANNEL
DIALOG ENHANCE: OFF
DYNAMIC RANGE: N/A
LEVELS MENU
UNDO CHANGES
DONE
This tells you that selecting the TUNER input (from the front panel or remote) will automatically “call up” 2
channel operating mode with dialog enhancement Off. Note that dynamic range adjustment is not
possible.
You may change any parameter by highlighting it with the Up/Down buttons and using < or > to scroll
through the available choices. For example, you can elect one of the following modes as the default for
the TUNER input:
2 channel (stereo)
Cinema EQ (with Dolby Pro Logic)
Dolby Pro Logic (no Cinema EQ)
Hall surround
Stadium surround
Jazz surround
5 channel surround (enhanced stereo)
These choices are not consistent from input to input. Dolby Digital, for instance, is not available when
you’ve selected TUNER, because TUNER is an analog input. In this way, the GTP-740 protects you from
making inappropriate choices
Note: If you change video formats, the menu screen will disappear. Do not panic. Just press
either the < or > button to restore the screen.
Once you’ve adjusted the default parameters for all inputs to your satisfaction, highlight DONE and press
the Select button, this memorizes your choices and takes you back to the main SETUP screen.
3.4 CHANNEL DELAY Screen
The term “delay” is often misunderstood. Conventional surround sound systems routinely
delay the sound going to the rear channels for a few thousandths of a second (a few
milliseconds - abbreviated “mS”) to enhance the apparent directionality of various effects.
In addition, the GTP-740 allows you to calibrate center channel delay.
