The boom is threaded internally with an XLR cable for a clean appearance and unhindered operation. Offering full 360° rotation and adjustable, spring-stabilized joints, the boom arm repositions quickly for optimal mic placement. The rugged AT2020 side-address studio condenser microphone features a low-mass diaphragm that is custom-engineered for extended frequency response and superior transient response for excellent vocal reproduction.
