About JK Audio teMix 4

Discover the unparalleled versatility and convenience of the JK Audio RemoteMix 4, a robust four-channel field mixer and headphone amplifier engineered for the dynamic needs of broadcast professionals. This innovative device is not merely a field mixer; it is a comprehensive communications interface that integrates seamlessly with various audio sources and systems.

Crafted for durability and portability, the RemoteMix 4 is encased in a rugged exterior that belies its compact size, making it an ideal companion for on-the-go broadcasting that is more resilient than a traditional lunch box. Its multifunctional design incorporates a phone line hybrid with a keypad, a PBX handset interface, and a 2.5mm cell phone interface, all optimized to work in unison for swift setup and reliable performance in the field-eliminating the need for an engineer to manage patch cables.

The RemoteMix 4 boasts HD Voice technology, ensuring crystal-clear 7 kHz Wide Band Speech for impeccable audio quality when paired with compatible phones and networks. Designed with live remotes in mind, it serves as an efficient phone line hybrid for studio talk shows or as a front-end mixer for various codecs, including POTS, ISDN, IP, and laptop-based systems.

For television applications, the RemoteMix 4 excels with its ultimate phone connectivity and four IFB feeds, enabling seamless sending and receiving of interview audio and IFB extraction from any business phone system or cell phone. This device is more than just a field mixer; it's a critical tool for ensuring successful shoots.

Enhancing audio quality, the Bass Boost feature adds depth before transmission, while a soft limiter prevents overdriving the phone line interfaces. The mixer's XLR output remains pre-limiter, offering a full-range signal. Additionally, the line-level cue input to the headphones makes the RemoteMix 4 the perfect complement to your codec.

Equipped with Bluetooth technology, the RemoteMix 4 prioritizes hands-free mode for cell phone connections and can also pair with other Bluetooth-enabled devices such as notebooks or tablets, providing a full audio bandwidth stereo connection wirelessly.

The unit includes convenient 3.5mm send and receive jacks for recording or integrating an MP3 player, with separate controls for headphone level and source selection. Users can monitor the pristine mixer output or combine it with the communication return and mix.

Understanding the importance of power management, the RemoteMix 4's phantom power generator activates only when necessary, conserving battery life with low noise, low power ICs throughout the design. The included 100-240 VAC desktop-style power supply takes precedence over battery power when active, with an automatic switch to batteries in case of power loss. The device also allows for hot-swapping batteries with separate compartments, ensuring uninterrupted operation.

In summary, the JK Audio RemoteMix 4 is a high-quality, compact, and multifunctional broadcast mixer that offers unparalleled flexibility and reliability for professional broadcasters seeking a durable and innovative solution for field operations.
