5.3 Activating analog modulations
► Use one of the following:
● Select "Modulation > Amplitude Modulation/Frequency Modulation/Phase Mod-
ulation > State > ON".
● Select "Modulation > MOD ON".
● Press the [Mod on/off] key.
[Mod on/off]
Activate one or more analog modulations and press the [Mod on/off] key to toggle the
state of them all.
Pressing the key again restores the status that was active before the last switch-off.
Remote command:

5.4 Modulation settings
Access:
► Select "Modulation" > "Modulation Sources".
The "Modulation" dialog contains all functions and settings to configure the analog
modulations, the LF signal sources for performing a modulation, and the LF signal
output.
The remote commands required to define these settings are described in:
