The all round wireless microphone with a built-in receiver

The DM20 is a small, advanced wireless microphone with a built-in receiver and mixer. The sound can be received from another Digisystem microphone and sent to one or more DH10, DE10 and DT10 receivers. 

The DM20 can be attached to the clothes with a clip or be used with an external microphone.
The DM20 is equipped with a special speech function called AGC which keeps the sound level comfortable at any time.
