Audio Technica AT831 Cardioid microphone with connector for use with AT unipak wireless transmitters – no cable.

The AT831CW-NC microphone is very small one piece microphone that can be plugged into any Audio Technica unipak transmitter directly with no cable. With this setup, you can almost think of this as a type of wireless ‘shotgun’ microphone as the mic will pick up any sound in the direction you aim it. The wireless transmitter becomes the ‘handle’.

The body of the microphone and connector are covered in black rubber for durability. The microphone is very small measuring about 3″ long and about .4″ wide.

The high quality AT831 microphone element used in this microphone is made by Audio Technica, a leader in the microphone industry. They offer the professional recordist the very best in sound quality at reasonable price, and offer performance unequaled in their price range. A removable premium foam windscreen is included at no extra cost.

This microphone, connected in this manner, is perfect for recording outdoors, sound effects, lectures, business meetings, interviews, etc. It is especially useful in situations where there is background noise that you are trying to reduce in your recording.
