RemoteMix x4 – Broadcast Field Mixer

RMx4™ combines a four-channel field mixer with a four-channel headphone amplifier. After all, what good is a field mixer if you do not have a flexible monitoring capability for the whole crew? 3.5 mm send and receive jacks for recording or playing back of recorded material. Separate headphone level and source selection controls for each headphone output. Monitor just the clean mixer output, or the Cue input plus the mix.

Great Sound

Four low noise, high headroom active balanced mic inputs feature extremely high common mode rejection for outstanding cable noise immunity. High-Pass filter removes room rumble and mic handling noise. Direct drive DC coupled XLR output for improved output cable noise immunity. A soft limiter prevents overdriving the full-duplex headset interface, while the master XLR and 3.5 mm outputs are pre-limiter (full range).

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.


RMx4 is designed for news, sports, and live remotes. Use it as a front-end mixer for your POTS, ISDN, IP or smart phone codec. XLR out, ¼” return to headphones.


RMx4 is designed for ENG, Sports, and interviews, with four ¼” headphone outputs. 3.5 mm TRRS provides 2-way IFB audio from your cell phone or notebook.
