JK Audio's RMx4 combines a four-channel field mixer with a four-channel headphone amplifier, The RMx4 is perfect for small press, hotel conferences, DNG, sports, interviews, live remote and news, and can be used as a front-end mixer for your POTS, ISDN, IP or smart phone codec.

Great Sound

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

Convenience

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.

Power Smart Design

Phantom power is not always needed, yet it can really drain 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. Separate compartments for hot swapping batteries.

Its rugged design allows for field use, and runs for up to 10 hours on two hot-swappable 9-volt batteries. The unit has XLR out with a ¼” return to headphones and four ¼” headphone outputs, along with 3.5 mm TRRS which provides 2-way IFB audio from your cell phone or notebook.
