The DH22 uses digital signal processing (DSP) technology to continually adapt to telephone-line conditions — providing consistent highquality sound and send to caller separation. The DH22 is a dual digital hybrid, allowing the connection of two telephone lines for on-air use. The two internal hybrids contain a common send audio input and the two telephone lines are internally conferenced. This means two callers can be on-air at once. Both callers’ audio can be combined as a single input on your console or as two separate outputs to two console inputs.
