SPD-HR21 is a 4-Pin Push-Power (Hirose-compatible) to 2.1 mm DC barrel jack cable designed for powering devices from Hirose 4-Pin distribution systems. It offers a secure locking connection on the Hirose side while providing a standard 2.1 mm centre-positive DC output.

This cable is ideal for sound mixers and location audio professionals who want to power their DC-based devices directly from a compatible power distro without additional adapters.

Compatible Hirose-based receivers include:

• Lectrosonics UCR411
• Lectrosonics UCR401
• Lectrosonics UCR211
• Lectrosonics UCR201

Because the SPD-HR21 outputs the unregulated voltage of your power distro (typically 9 to 18V), it should only be used with devices that can safely accept this voltage range.

Important: While it can power any 2.1 mm DC barrel jack device, do not use this cable with gear that requires a tightly regulated 12V input or has a narrow voltage tolerance.

Additional features:

• Hirose 4-Pin compatible locking connector
• 2.1 mm DC barrel plug with centre-positive wiring
• Durable and flexible cable designed for field use
• Lightweight design for bag and cart setups

This cable is a simple, reliable solution for powering DC-equipped devices directly from a Hirose-compatible distribution system, making it a useful addition to any professional audio kit.
