JTS ST-850 Electret Condenser 312mm Gooseneck Microphone with Wireless Base Option



The JTS ST-850 is a great option in situations where you need an easy to install wireless gooseneck microphone. The ST-850 is compatible with JTS transmitters such as PT-900B, PT-850B, PT-920B (G), PT-950B and PT-990B. In these situations the microphone gets power from the wireless transmitter. When used as a straight ahead wired gooseneck microphone simply connect the ST-850 to a microphone cable with phantom power and it will work as a normal gooseneck microphone. It has automatic wired / wireless mode transformation and no switching is needed.
