JK Audio BSETM4 BlueSet Wireless Headset Interface for Intercoms (4-Pin XLR-M)

Wireless Audio Interface for Intercom Communication

The JK Audio BlueSet M4 is a compact wireless interface designed for use with most PL beltpacks in professional intercom systems. By plugging into the beltpack’s headset connector, it introduces Bluetooth technology that allows seamless audio transmission between the intercom and either a cell phone or a Bluetooth headset. This makes it easier for crews, technicians, and production teams to communicate effectively without being restricted by cables.

Bluetooth Connectivity with Extended Range

With its built-in Bluetooth functionality, the BlueSet M4 provides reliable wireless communication up to 33 feet away. This feature is especially useful in live event production, broadcasting, and theater operations, where staff often need to move freely while staying connected to the intercom system. Whether paired with a cell phone for remote coordination or a wireless headset for mobility, the unit ensures strong, stable connections.

Multiple Connection Options for Flexibility

The BlueSet M4 comes equipped with a 4-pin XLR-M connector that attaches securely to the beltpack, while its 3.5mm stereo headset jack adds even more versatility. The audio signal is separated so that the left channel delivers a clean microphone feed, while the right channel handles the Bluetooth return. This configuration provides clear monitoring and ensures accurate audio capture when needed for recording purposes.

Convenient Mode Switching for Different Setups

A built-in switch allows users to quickly toggle between phone mode and headset mode. This feature simplifies the workflow in fast-paced environments where communication needs can change rapidly. With a simple adjustment, operators can adapt their connection type without interrupting their workflow, making the BlueSet M4 a practical choice for stagehands, camera operators, and production managers.

Rechargeable Power for Long Sessions

Powered by an internal lithium-ion battery, the BlueSet M4 offers up to 10 hours of operation on a single charge. The included USB charging capability makes recharging simple and efficient, minimizing downtime during demanding production schedules. This long-lasting battery performance ensures reliability throughout extended events or long workdays.

Compact and Reliable Design for Professionals

Designed with durability and portability in mind, the BlueSet M4 is lightweight yet rugged enough for professional environments. Its compact size makes it easy to carry as part of a production kit, while its high-quality connectors and sturdy build provide confidence in critical communication setups. For production teams looking for a dependable wireless audio solution, this unit delivers both performance and practicality.
