DUCKING
The Hybrid has an automatic gain adjustment of the incoming signal from the caller when the
presenter speaks. This feature both improves the side tone reduction and gives the presenter a
level advantage over the caller when he interrupts the caller. When both parties are speaking the
caller’s signal is reduced then.
