If the command is accepted, the “ACTIVE” LED goes dark for a moment.
Example 1:
To change the behavior in such a way that all three preamps are on MIDI channel 5, mapped to controller
numbers 64 to 88, we need to adjust the settings in slot 00.
We assume that DIP-Switches 1/2 are OFF/OFF, and the device has its default configuration of MIDI base
channel 0x01.
set the MIDI channel base (parameter 01) to 0x04
(the channel base is the number of the first MIDI channel minus 1)
the controller number base (parameter 05) to 0x40
the number of controllers per channel (parameter 06) to 24 (0x18):
F0 7F 01 04 05 01 01 02 00 00 01 04 00 05 40 00 06 18 00 F7
Note that the MIDI channel where the controller responds to has been altered. The new MIDI channel becomes
effective after power is cycled. Subsequent commands then need to start with F0 F7 05.
Example 2:
We assume that DIP-Switches 1/2 are OFF/OFF, and the device has its default configuration of MIDI base
channel 01.

15.3. Preamp requirements for remote gain control
The controller can be adjusted to function with nearly every microphone preamp, if it meets the following
conditions:
