Polsen RC-77-U User manual

THANK YOU FOR CHOOSING POLSEN.
The Polsen RC-77-U is a large-diaphragm studio condenser USB microphone ideal for singers,
songwriters, and podcasters who want to record high-quality sound directly to their computer.
The stylish, retro look of the RC-77-U makes it an eye-catching addition to any studio.
This retro-styled microphone is Mac and PC compatible and connects directly
to a computer’s USB port. No drivers, power supply, or audio interface are
necessary to begin recording. Launch your recording software, plug in the
microphone, and you’re ready to record. A headphone output provides low-
latency volume adjustment, and a mute button gives you additional control.
In addition to the extreme ease of operation, the large 32 mm diaphragm delivers
clean and natural sound. An integrated dual-stage grille minimizes pops and
vocal plosives while protecting the capsule from corrosive moisture. The cardioid
polar pattern focuses on the source in front of it while minimizing off-axis
sound, and it makes the RC-77-U an excellent choice for recording vocals.
