CAP51-IK is a stand-alone harness cable designed for interfacing with an MCR41 receiver. It ends in a DB25 connector to the MCR41, provides an isolated XLR-3M output with an audio transformer and about 30 dB attenuation, and includes a Hirose connector for camera interfacing. The assembly supports analog audio breakout and direct camera connection for broadcast and professional event applications, with compact, field-serviceable construction.
