Presenting the Conference Microphone DC20
The Conference Microphone DC20 is an advanced microphone offering the
option of setting the size and shape of the sound registering area. It can be
wirelessly connected to two telephones via Bluetooth (mobile/portable, etc.)
as well as to a landline using the original Telelink accessories. The DC20 is

several cordless microphones from the Digisystem series.
