EXC-GT – FM super-compact transmitter series
User’s manual – Page 38 of 98
described in section 8.1.e.
When the limiter begins to intervene, the modulation distortion increases. As such, the modulation sensitivity should be
adjusted (
2
section 10.3.c) so the limiter intervenes sporadically. Using this approach, its operation is generally imperceptible.
10.3.f MODE
setting
Used to define whether the transmitter operates in mono or stereo, and its preemphasis value.
The display shows the following:
Mode
– followed by
Mono
(from the
RIGHT
input (
2
ref. [22] section 5.2),
Stereo
,
Mono L+R
(monophony obtained through the sum of the
stereo channels), or
Mpx
(external multiplex modulation signal originating from the
MPX
input (
2
section 5.2 ref. [17]).
Preemphasis
– followed by the current preemphasis value, expressed in microseconds.
To change the auxiliary modulation:
1)
Ensure that the
EDIT
option is selected; otherwise, turn the knob to select it, then press to confirm. A value will be indicated
after
Mode
.
2)
Turn the knob to change the setting to
Mono
,
Stereo
,
Mono L+R
, or
Mpx
according to your requirements, then press the
knob. A value will be indicated after
Preemphasis
.
3)
Turn the knob to change the setting to
0
,
25
,
50
, or
75
microseconds, according to your requirements (50 microseconds for
Italy), then press the knob to set the value.
4)
Using the knob, select
OK
to save the settings,
EDIT
to make further changes, or
ABORT
to exit without saving the new
settings, then press to confirm (for further details regarding these commands, see
2
9.4.a).
10.3.g DISPLAY
setting
Used to optimize display legibility, based on ambient lighting conditions and the angle of the visual field.
This screen shows:
Backlight
– followed by the current backlighting value (in the example, 3)
Contrast
– followed by the current contrast value (in the example, 4)
To change these parameters:
1)
Ensure that the
EDIT
option is selected; otherwise, turn the knob to select it, then press to confirm. A value will be indicated
after
Backlight
.
2)
Turn the knob to change the backlighting, which will immediately change based on the setting selected (three levels are
available; 3 corresponds to maximum illumination), then press to confirm. A value will be indicated after
Contrast
.
3)
Turn the knob to change the contrast, which will immediately change based on the setting selected (twenty levels are
available; 1 corresponds to maximum contrast), then press the knob to set the value.
4)
Using the knob, select
OK
to save the settings,
EDIT
to make further changes, or
