Rainbow Aircraft Inc. V10 Manuel D’Utilisation
First level menu functions
This chapter describes the various first level menu functions provided in the V10 transceiver.
Ambient noise suppression
Your V10 transceiver provides four different ambient noise suppression systems. These can
be selected using the “Type” selection.
The up and down arrow buttons can be used to select the strength or effectiveness of the
selected system.

VOGAD system
The VOGAD system is a propriety system developed by MGL Avionics. This system
uses gain shaping using digital audio processing. Here the voice strength envelope is
detected and used to modulate the gain of the microphone amplification system. A
level setting of 1 is suitable for most applications. Three further levels are provided with
different characteristics. The system should be selected such that ambient noise is
sufficiently suppressed while voice comes through loud and clear. It is important to set
your microphone gain not too high to allow correct match of the microphone level to the
system. A high level of gain may allow noise to pass the threshold.
A correctly setup VOGAD system will cause your microphone to become very
directional so it needs to be placed directly in front of your mouth.

VOX system
This system simply switches your microphone off if the level of sound received by the
microphone is below a preset level. The switching is done in a digitally controlled “soft”
manner so no clicks are audible.
Adjust the level such that ambient noise is just less than what is needed to open the
microphone. If the level is set too high, you may find that parts of your first syllable are
not sufficient to open the microphone.
