NOISE THRESHOLD
You can mute noise (e.g. from a mixing desk, or keyboards) which might appear during program pauses, by
using the built in NOISE GATE function. As soon as the signal level is lower than the Threshold you will have
set, the ULTRA-CURVE PRO's outputs will be muted. The Threshold may be anywhere from OFF to -44 dB,
the scale again referring to the digital maximum. Additionally, you can deactivate the NOISE GATE by
choosing the setting OFF.
2.2 Real Time Analyzer
Fig. 2.7: Main RTA window
The RTA display shows the 31 1/3-octave frequencies, with the overall level to the right, similar in general to
the equalizer display. To the left is the pictogram containing the softkeys. By moving the horizontal cursor
keys or the one pointing upwards, you can freeze the display, simultaneously displaying a set of crosshairs,
and an information window (see figure on top of next page). Using the cursor key pointing downwards will
make the crosshairs and the information window disappear as well as de-freeze the display. The informa-
tion window displays the precise values pertaining to the selected frequency, along with the number of the
RTA program currently in use. By moving the crosshairs to any given frequency band, or the overall level,
you can display the details of the chosen band in the information window.

the
highest level reached on this frequency up to the point in time when the display was frozen (the maximum
values stored in memory can be replaced). The levels displayed in the RTA refer to the digital maximum.
PROGRAM: Shows the current RTA program number (1-10). In contrast to EQ programs, it is not possible to
name RTA programs. If after approx. 4 seconds, no cursor key is pressed, the information window will disap-
pear. The display, however, remains frozen. By re-pressing the RTA key, you can return the ULTRA-CURVE PRO
to the normal, dynamic display.
