JK Audio RemoteMix 4 Front

All In One.

RemoteMix 4 is a four channel field mixer and headphone amplifier. More than just a field mixer, this is a communications interface. RemoteMix 4 features a phone line hybrid and keypad, a PBX handset interface, and a cell phone interface. All this in a tough, portable unit that’s smaller than a lunch box. All-in-one is an understatement. These parts were designed to work together and save setup time in the field. No need to send an engineer with patch cables. All the pieces work together in one reliable unit.

RemoteMix 4 gives you the ultimate phone connectivity with four IFB feeds. Imagine being able to send and receive interview audio, and pull IFB out of any business phone system, even your cell phone. More than a field mixer, this is a shoot saver.


RemoteMix 4 was designed for live remotes. Use it as a phone line hybrid, calling into your studio talk show hybrid. Use it as a front end mixer for your POTS, ISDN or IP codec. Use it with your laptop codec.

Great Sound

Bass Boost adds some low end before sending the signal down the phone line. A soft limiter prevents overdriving the phone line interfaces, while the mixer XLR output is pre-limiter (full range). Line level cue input to the headphones make RemoteMix 4 a perfect companion to your CODEC.

Bluetooth Wireless Technology

RemoteMix 4 will first attempt to connect in hands free mode to a cell phone. If this type of connection is not available, it will connect to any other product, such as a notebook or portable that allows a Bluetooth wireless connection. This wireless headphone mode offers a full audio bandwidth stereo connection.

Wireless Phones and Notebooks

Simply plug RemoteMix 4 into the 3.5 mm headset jack of your wireless phone or notebook computer. Your cell phone will recognize RemoteMix 4 as a headset which will disable the internal mic and speaker.

ISDN, PBX, and VoIP Systems

Unplug the handset from any phone and plug the coily cord into RemoteMix 4. You can now send and receive audio through the ISDN, PBX, or VoIP telephone set.


Convenient 3.5 mm send and receive jacks for recording the show, or mixing in your MP3 player. Separate headphone level and source selection controls. Monitor just the clean mixer output, or the communication return plus the mix.

Power Smart Design

Phantom power is not always needed, yet it can be a real drain on batteries. The phantom power generator only runs if any of the rear panel 48 V switches are set to “ON” position. Low noise, low power ICs are used throughout to preserve battery life. The 100-240 VAC desktop style power supply (included) overrides the battery power only when the supply is actually providing power. If the power goes out, the batteries automatically cut in. Use one battery or two. Separate compartments for hot swapping batteries.

*HD Voice: While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD Voice calls offer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives voice a more natural sound, while the additional upper octave dramatically improves speech clarity and intelligibility.

*Wireless HD Calls: To take advantage of this extended bandwidth, both phones on the call must support HD Voice, and both phones must be on the same carrier, in coverage areas that support HD Voice.
