Broadcast Quality USB Microphone Seamless integration was the idea, and it was obtained by creating a studio dynamic microphone with unparalleled A/D converters, so that the microphone can be plugged into any computer with no in/out boxes, no expensive computer pre-amps, just a USB cable. The Podcaster offers an end-address configuration, the clarity of RØDE's tailored-for-voice frequency response, an 'ON' L.E.D, a direct headphone amp, and of course very low self noise. The Podcaster opens up possibilities for anyone who records audio - from podcasters, journalists and students to business people adding audio files to websites and multimedia presentations.
