JK Audio RMX4 RemoteMix x4 Broadcast Field Mixer

Four Channel Broadcast Field Mixer with Headphone Amplifier

The JK Audio RemoteMix x4 is a professional four-channel broadcast field mixer combined with a four-channel headphone amplifier, designed to meet the demands of remote broadcasting, live events, interviews, and sports coverage. With flexible power options, rugged construction, and a complete range of input and output connections, it delivers a portable solution that integrates multiple functions into one compact unit.

Microphone Inputs with Phantom Power Options

The mixer features four balanced XLR microphone inputs that provide low-noise, high-headroom performance for professional audio capture. Channels 3 and 4 include mic/line switches for additional flexibility, while individually selectable 48V phantom power allows condenser microphones to be used alongside dynamics. Each input has peak indicators to help users maintain clean levels without distortion.

Independent Headphone Monitoring for Multiple Users

Equipped with four 1/4-inch headphone outputs, each with its own level control and source selector, the RemoteMix x4 allows multiple users to monitor audio simultaneously. This makes it ideal for production crews, on-air talent, or live interview scenarios where clear monitoring is critical. A dedicated headphone cue input further enhances versatility for monitoring external feeds.

Professional Output Options for Broadcast Flexibility

The direct-drive DC-coupled XLR master output delivers a wide 20 Hz to 20 kHz frequency response with excellent resistance to cable noise. Additionally, 3.5mm stereo line inputs and outputs allow seamless connection to portable recorders, codecs, or consumer devices. An integrated soft limiter prevents overdriving on the full-duplex headset interface, ensuring clean communication while preserving broadcast quality.

Built-In Tools for Clean Audio Performance

The RemoteMix x4 includes a switchable 120 Hz low-cut filter that reduces unwanted bass rumble from handling noise or environmental vibrations. This filter helps maintain clear and natural-sounding audio, even in challenging environments. LED VU meters provide accurate visual monitoring of levels, making it easy to manage signals on location.

Connectivity for Phones and IFB Systems

A wired headset interface with a 3.5mm TRRS plug provides two-way IFB audio via smartphones or notebooks. This makes the unit particularly useful in modern broadcast workflows where mobile integration is often required. With its hybrid features, the RemoteMix x4 can serve as both a field mixer and a communication bridge.

Portable Design with Dual Power Options

For field use, the unit operates on hot-swappable 9V batteries, offering flexibility and uninterrupted operation. It can also run on the included external AC power supply, which automatically shifts to battery backup if AC power fails. This redundancy ensures reliable operation during critical live broadcasts. Built in the USA, the RemoteMix x4 is constructed to withstand the rigors of professional use.
