RCF F 12XR Helimikser

12-Channel Analog Mixer with PRO DSP FX

The RCF F 12XR pairs a fully balanced audio path with onboard PRO DSP FX and a USB stereo interface. Conceived and engineered in Italy, the desk carries the analog DNA of the company's professional E Series into a portable format. Microphones, instruments, and a laptop can sit on the metal chassis at once, with the stereo mix routed straight to a DAW for project recording.

What Makes This Mixer Different

Most desks in this tier cut corners on EQ or dynamics. The console ships with four real analog compressors on channels 1–4 and full parametric EQ on every mono strip. A 1 MOhm Hi-Z input accepts passive guitar and bass pickups directly, while the internal universal power supply handles any mains voltage from 100 V to 240 V without adapters.

Channel Architecture

Twelve input strips cover vocals, instruments, and stereo playback without repatching.

• Channels: 12 total (6 mic, 4 mono line, 4 stereo line) — covers vocals, instruments, and stereo sources on one surface.
• Mic input impedance: 14 kOhm — clean signal transfer with dynamic and condenser microphones.
• At a Hi-Z input impedance of 1 MOhm, the circuit preserves the full tone of passive guitar and bass pickups.

EQ, Compressors, and Low Cut

The console ships with the analog tools engineers reach for when shaping a vocal or instrument.

• 3-band mono EQ: High ±15 dB @ 10 kHz shelving, Mid ±15 dB @ 1.25 kHz bell, Low ±15 dB @ 100 Hz shelving
• Compressors: 4 single-control analog compressors on channels 1–4 — fast audible vocal smoothing.
• The 80 Hz Low Cut filter clears stage rumble and handling noise before the mix bus.

FX Engine and USB Recording

Combined, the onboard PRO DSP FX engine and USB port deliver ambience, time-based processing, and DAW capture together.

• Onboard FX: 16 PRO DSP presets — Reverbs (Halls, Rooms, Plates, Spring), Delays (Mono, Stereo, Multitap), Chorus, Flangers, Echoes
• USB audio interface: Type-B, 2 playback / 2 record tracks, 44.1 / 48 kHz
• Main / Aux / Group outputs hit 28 dBu on XLR / Jack, delivering enough headroom to drive long cable runs into active speakers.

Who This Mixer Is For

The RCF F 12XR is the right choice for solo performers, duos, podcasters, and small bands who want an all-in-one analog surface with reliable USB recording. Live crews running small venues and houses of worship will lean on the 80 Hz low-cut, dedicated Hi-Z input, and four onboard analog compressors to tighten vocal mixes in seconds. An optional RM-KIT rack-mount kit and a 4.5 kg metal chassis make transport to rehearsal painless.

RCF — Italian Pro Audio Heritage

This console sits inside RCF's next-generation F Series, building on the analog legacy of the professional E Series. Engineered by R&D in Italy, the unit ships ready to record a first session into any DAW at 44.1 or 48 kHz straight out of the box.
