ABSTRACT A control unit for controlling operation of a plurality of audio teleconference terminals includes a plurality of inputs for connection to respective teleconference terminals to receive speech signals therefrom, and variable impedance devices having high and low impedance conditions connecting each input to a plurality of outputs, each output being associated with a particular input. The arrangement is such that when a variable impedance device is in a low impedance condition signals can be fed from the input associated with that variable impedance device to all outputs other than the one with which it is associated. The control unit responds to speech signals from said inputs to control the variable impedance devices so that at least two of the inputs at which speech signals are received can be coupled to the outputs such that at least two terminals can be connected in open loop teleconference and any remaining terminals can receive the conference.
