RCF F 10XR Analog Mixer.With high-quality sound in five formats ranging from 6 to 24 channels, RCF's new F Series mixers build on the rich analogue heritage found in the professional E Series. Totally conceptualised and created by the RCF R&D team, this powerful tool is ideal for musicians and sound enthusiasts. Each mixer comes with a full balanced audio path from input to output with the exclusive PRO DSP FX: 16 professional effects like Reverbs (Halls, Rooms, Plates, Spring), Delays (Mono, Stereo, and Multitap), Chorus, Flangers, and Echoes. The mixers are housed in a strong metal chassis. For stereo recording on a computer-based DAW and 2-channel playback, the models F-10XR, F-12XR, F-16XR, and F-24XR all come with a USB audio interface.
