set the time constant of each of the output filters.
SLOPE 2
The roll-off of the outputs filters can be set, using this control, to either 6 dB or
12 dB per octave (Fast time constant mode) or 6 dB, 12 dB, 18 dB or 24 dB per
octave (Normal time constant mode).
Pressing the Output Filter Menu 1 key selects the Output Filter 1 Menu, while
pressing the Previous Menu key returns control to Main Menu 1.
In dual harmonic mode, when Main Menu 1 is displayed, pressing a key adjacent to
the Output Offset & Expand item accesses the Output Offset Harm 1 menu, which is
shown in figure 5-68.
Figure 5-68, Dual Harmonic Output Offset Harm 1 Menu
The Output Offset Harm 1 menu has three controls affecting the instrument's
X1 channel and Y1 channel outputs and a key to access a further sub-menu which
has corresponding controls for the X2 channel and Y2 channel. Changes to the
setting of these controls can be made by using the adjacent
currently active selection being highlighted.
X1 OFFSET and Y1 OFFSET
These controls, which duplicate the Main Display X1 OFFSET and Y1 OFFSET
controls, allow manual adjustment of the X1 channel and Y1 channel output offsets.
The offset level set by the controls, which can be any value between -300% and
+300% in 0.01% steps, is added to the X1 channel or Y1 channel output when the
X1 channel or Y1 channel offset is switched on. Adjustment is faster using the
Keypad or Active Cursor controls - see section 4.1.04.
The values are set automatically by the Auto-Offset 1 function, which also switches
on both X1 channel and Y1 channel output offsets.
OFFSET 1 STATUS
This control allows the X1 channel and Y1 channel output offsets, set by the above
level controls, to be switched on to either or both outputs, or to be switched off. It
therefore has four settings, as follows:-
keys, with the
