A Varidirectional Condenser Microphone
This condenser microphone has a self-contained power supply and uses hearing-aid type batteries. Cable connection is by means of a conventional 2-conductor shielded cable. The microphone, already somewhat more directional than a unidirectional microphone, can be made still more directional by applying an 18-in. long tubular attachment weighing only 5 oz. Total weight of unit, including mounting and windscreen, is 1 lb 12 oz. Open-circuit output voltage at 250-ohm tap is 1.6 mv/dyne.
