Position Modulation
Position Modulation is an effect in which the source video is position-mod-
ulated through an additive process with either a single wave train, or two
wave trains with the second wave at a right angle to the first. Each of the
two wave trains may be selected independently from a set of modulation
patterns. Soft knobs are provided which change wave amplitude, fre-
quency, phase, speed, and angle.
Pos Mod Horiz/Vert Position
Press the second column KURL MODE to highlight to POS MOD menu as shown
below.
Position Modulation menu functions include:
POSITION — provides the following adjustment parameters:
HORIZ POS selects a modulation pattern which displaces the source video
in the direction determined by the ANGLE soft knob.
VERT POS selects a modulation pattern which displaces the source video
at right angles to the direction determined by the ANGLE soft knob.
MODIFY — you can modify the following modes.
MODULATN — amplitude, frequency, speed, and angle control is pro-
vided through the soft knobs (see descriptions below).
PATTERN — choose this mode to be able to select a modulation pattern
from the two columns of POS MOD PATTERN soft buttons.
PHASE MODE — you can set the following modes:
LOCKED — The modulation starts at a fixed location. The wave train can
be moved to different positions with the soft knobs.
