Compact Wireless Interface for Beltpacks

The JK Audio BlueSet F4 is a compact Bluetooth-enabled audio interface designed to connect directly to most PL beltpacks used in intercom systems. By plugging into the beltpack’s headset connector, it enables seamless wireless communication between the beltpack and a Bluetooth cellphone or headset. This flexibility allows you to keep the beltpack stationary while maintaining reliable communication up to 33 feet away.

Whether you are managing communication backstage or on location, the device ensures a secure and consistent audio connection without restricting mobility.

Multiple Connectivity Options

The BlueSet F4 is equipped with a 4-pin XLR-F connector for attaching to your beltpack, along with a 3.5mm stereo headset jack that delivers a mic-level output signal. This output is ideal for recording applications, with the left channel providing a clean microphone signal and the right channel carrying the Bluetooth return audio. This dual-channel setup offers flexibility for both monitoring and capturing high-quality audio.

Convenient Switching Between Devices

A built-in switch allows you to toggle between phone mode and headset mode with ease. This makes it simple to adapt to different communication needs on the fly, ensuring that the system integrates smoothly with existing equipment and workflows.

Long-Lasting Rechargeable Battery

The BlueSet operates for up to 10 hours on its internal rechargeable lithium-ion battery, ensuring that it can keep up with the demands of long shifts, rehearsals, or live events. Recharging is straightforward using the included USB connection, allowing for quick and efficient power management.

Durable and Portable Build

Engineered for the rigors of professional use, the BlueSet features a rugged and compact design that can handle repeated use in the field. Its lightweight profile ensures it won’t add unnecessary bulk to your gear, while still delivering reliable wireless connectivity.
