G -------
The following parameters can be edited:
F
Filter center frequency adjustable from 20 Hz to 20 kHz in 3 % steps.
Q
The Q of the filter is adjustable from 0.5 ... 25 in 10 % steps. In
addition, the bandwidth (BW) as a result of the Q is displayed as a
value (2.0 ... 0.04 octaves) in a non-editable field.
G
The parameter "Gain" (G) cannot be edited in "Notch" mode. The
center frequency is fully attenuated (⇒ –∞
dB).

ft
A signal delay is available for each channel independently to allow
delay settings of up to 340 ms. (100 m/328.1 ft).
on/off
Switches the delay on/off without affecting the entered delay value.
[Value]
Delay time adjustable from 0.3 to 340 ms in steps of 0.1 ms or a
corresponding value depending on the unit selected.
[Unit]
Enables selection of the delay unit in either milliseconds [ms]; meters [m];
or feet [ft].

Selecting "Levels" and pushing the encoder enters the submenu.
Turning the encoder one detent to the right and back toggles between
channel A and B.
Pushing the encoder exits the submenu.
In the "Levels screen" the following values are displayed as bar graphs
and/or as numeric values:
Input gain/Temperature of the device
In the first line the input gain setting of the respective channel is
displayed as the numeric value in dB and the temperature of either the
amplifier or the power supply (whichever value is higher).
Input
Input signal level as bar graph and the numeric value is displayed in
dBu. The small vertical mark [A] represents the threshold of input level
where an input overload occurs (red OVL LED). The colon [B] acts as a
peak hold for 1 s.
Headr. (Headroom)
The bar graph shows the relationship between modulation and gain
reduction (GR). The small vertical mark [A] indicates the gain reduction
threshold (0 dB headroom), the colon [B] acts as a peak hold for 1 s. The
gain reduction (GR) LED (yellow) indicates a gain reduction of more than
3 dB.
